The present disclosure more specifically relates to observing, deciding, selecting and switching among a plurality of transceiving antennas via an intelligent wireless control system in an information handling system.

BACKGROUND

DETAILED DESCRIPTION OF THE DRAWINGS

As mobile computing infrastructure evolves worldwide to enable mobile information handling systems to transmit and receive larger amounts of data more quickly and easily while on the move, the abilities of these mobile information handling systems to receive and transmit various signals simultaneously increase in demand. Information handling systems including those that are mobile in embodiments of the present disclosure address this need by employing a plurality of antenna systems for communication via wireless links operating on a variety of radio access technologies (RAT). For example, a mobile information handling system in an embodiment of the present disclosure may employ separate antenna systems for Wi-Fi signals, wireless wide area network (WWAN) signals, Bluetooth signals, and wireless local area network (WLAN) signals. WWAN signals in embodiments of the present disclosure may include 2G standards such as GSM, 2.5G standards such as GSM EDGE and GPRS, 3G standards such as W-CDMA/UMTS and CDMA 2000, 4G standards such as LTE, LTE-A, LTE-LAA, emerging 5G standards, or WiMAX, small cell WWAN, and the like. Wi-Fi and WLAN signals in embodiments of the present disclosure may include wireless links adhering to standards such as, for example, IEEE 802.11 WiFi, IEEE 802.11ad WiGig, IEEE 802.15 WPAN, and IEEE 802.11ax-2021 (e.g., WiFi 6 and 6E, 6 GHz technologies). In other aspects, several antenna systems may be available for each RAT to enable aggregated data communications such as via plural multiple in, multiple out (MIMO) streams (e.g., Wi-Fi MIMO or cellular MIMO) to enhance data bandwidth or reliability.

Information handling systems also include a number of peripheral devices. Among the number of peripheral devices, one or more may include wireless peripheral devices that communicate with the information handling system wirelessly via an antenna system. For example, a wireless peripheral device may include a wireless mouse. In this example, the wireless mouse may include an antenna such as a Bluetooth antenna that communicates using a Bluetooth protocol or other protocols, for example, a Wi-Fi IEEE 802.11 communication standard. Peripheral devices may operate under yet other wireless protocols and with antennas such as under small cell cellular protocols such as under 5G New Radio protocols as discussed herein. As such, the information handling system may communicate with the wireless mouse or other peripheral devices using one of the antennas within the information handling system whether that antenna is a dedicated antenna used for Bluetooth communications, or a repurposed antenna for use to communicate with the wireless mouse. Similarly, a plurality of other wireless peripheral devices may be used during operation of the information handling system such as a wireless display device, a wireless headset, a wireless virtual reality headset, among others.

In addition to the antennas used to communicate with the wireless peripheral devices, the information handling system may include an antenna to be operatively coupled, wirelessly, to an information handling system management system such as Dell Optimizer®. This remote information handling system management system may operate as a management and operations service provider administrator that is placed between information handling system (e.g., a host device) and a wireless network service provider whether administered and owned by an enterprise or contracted with an outside wireless network provider. This communication may be an out-of-band (OOB) communication established to receive load statistics and network slicing data at the information handling system.

Current configurations involving a plurality of antenna systems operating on a variety of RATs encounter potential problems associated with interference between each of the antennas, compliance with Federal Communications Commission (FCC) standard absorption rate (SAR) requirements across all antennas, a received signal strength indicator (RSSI), base rate over range performance of the plurality of available antennas due to antenna radiation pattern coverage, available of networks to the information handling system to operatively couple to, and incompatibility between radio modems manufactured by different upstream devices, among other system operation and connection metrics. For example, a signal strength (e.g., as a detected RSSI) associated with a WLAN communication access point may be inferior to the signal strength associated with a WWAN communication access point. In another example, operation of one antenna as compared to another antenna within the information handling system may be impeded via a user's body part such that a radio frequency (RF) signal cannot be transmitted or received. Embodiments of the present disclosure address this issue by providing an antenna controller capable of switching from one set and type of antenna device to another based on specific absorption rate (SAR) data from a plurality of SAR sensors, RSSI indicators, system operation and connection metrics including the RSSI data, from the antenna controller executing a sideband serial messaging protocol, and configuration data descriptive of a configuration of the information handling system in order to increase the reliability of signal and transmission and reception of data across any type of network.

Further, current configurations involving a plurality of antenna systems operating on a variety of RATs encounter potential problems associated with dedicated antennas of the various radio frequency (RF) subsystems to support each RAT. The RF subsystems include an oscillator, a radio front end, and other circuitry used to transmit a signal to each antenna. These resources are dedicated and optimized at the host device (e.g., user's information handling system) to operate on those specific RATs. Having dedicated antenna resources to operates under dedicated RATs limits the transception capabilities of the information handling system may also lead to a sub-optimized connectivity for a given technology without consideration of the environment or eco-system the information handling system is operated within. The present specification describes an information handling system that learns about the usage persona of devices in which the information handling system operates in to dynamically change the assignment of the plurality of antennas to be operatively coupled to the or more peripheral devices and plurality of operating wireless links at various RF subsystems thereby creating a connectivity resource mapping. In the present specification and in the appended claims, the term “persona” is to be understood as a state in which an information handling system may operate. For example, a “system configuration persona” describes, at least partially, a detected configuration the information handling system is in. Similarly, “wireless ecosystem persona” describes peripheral telemetry capabilities and/or system operation and connection metrics to one or more networks (e.g., WLAN and WWAN). Additionally, “link persona” may describe the links available to the information handling system for data transmissions such as available Bluetooth, Wi-Fi, and cellular links as well as types of data needs for an information handling system from operating applications. Further, “usage persona” may describe whether any number of sensors have detected the presence of a user near the information handling system (e.g., human proximity) at any given time.

The RF subsystems130-1,130-2,130-3may contain individual subscriber identity module (SIM) profiles for each technology service provider and their available protocols for any operating subscriber-based radio access technologies such as cellular LTE communications.

In an embodiment, the wireless interface adapter120may provide connectivity to a one or more of the peripheral devices that may include a wireless video display device110, a wireless keyboard172, a wireless mouse170, a wireless headset174such as a virtual reality headset and/or a microphone and speaker headset, a wireless stylus176, and a wireless trackpad178among other wireless peripheral devices used as input/output (I/O) devices112.

As described herein, an antenna controller140may execute an antenna selection algorithm164in order to provision one or more of a plurality of antennas for use with the wireless coupling of these wireless peripheral devices to the information handling system100.

The wireless interface adapter120, also known as a wireless interface device, may also include antennas132which may include any number of tunable antennas for use with the system and methods disclosed herein. In the embodiment shown inFIG.1, the antennas132may include a first antenna148, a second antenna150, a third antenna152, a fourth antenna154, a fifth antenna156, and a sixth antenna158. However, the present specification contemplates that the antennas132may include more or less of the number of individual antennas148,150,152,154,156,158shown inFIG.1. Additional antenna system modification circuitry (not shown) may also be included with the wireless interface adapter120to implement coexistence control measures via an antenna controller140as described in various embodiments of the present disclosure.

In some aspects of the present disclosure, the wireless interface adapter120may operate two or more wireless links. In a further aspect, the wireless interface adapter120may operate the two or more wireless links with a single, shared communication frequency band such as with the 5G standard relating to unlicensed wireless spectrum for small cell 5G operation or for unlicensed Wi-Fi WLAN operation in an example aspect. For example, a 2.4 GHz/2.5 GHz or 5 GHz wireless communication frequency bands may be apportioned under the 5G standards for communication on either small cell WWAN wireless link operation or Wi-Fi WLAN operation. In some embodiments, the shared, wireless communication band may be transmitted through one or a plurality of antennas or antennas may be capable of operating at a variety of frequency bands. In a specific embodiment described herein, the shared, wireless communication band may be transmitted through a plurality of antennas used to operate in an N×N MIMO array configuration where multiple antennas148,150,152,154,156,158are used to exploit multipath propagation which may be any variable N. For example, N may equal 2, 3, or 4 to be 2×2, 3×3, or 4×4 MIMO operation in some embodiments. Other communication frequency bands, channels, and transception arrangements are contemplated for use with the embodiments of the present disclosure as well and the present specification contemplates the use of a variety of communication frequency bands.

In other aspects, the information handling system100operating as a mobile information handling system may operate a plurality of wireless interface adapters120for concurrent radio operation in one or more wireless communication bands. The plurality of wireless interface adapters120may further share a wireless communication band or operate in nearby wireless communication bands in some disclosed embodiments. Further, harmonics and other effects may impact wireless link operation when a plurality of wireless links are operating concurrently as in some of the presently described embodiments. The radio transmission or reception operates under the wireless interface adapter120which is made to execute an antenna selection algorithm and potentially make antenna system adjustments according to present disclosure. In an embodiment, any of the antennas148,150,152,154,156,158may operate as dual band antennas that transceive at 2.4 GHz and 5 GHz, 2.4 GHz and 6 GHz, or 5 GHz and 6 GHz for example. Additionally, the dual band antennas may transceive at concurrent dual-band modes allowing transception to occur via at least two different frequencies such as 2.4 GHz and 5 GHz to communicate with a network and a peripheral device.

The wireless interface adapter120may operate in accordance with any wireless data communication standards. To communicate with a wireless local area network, standards including IEEE 802.11 WLAN standards (e.g., IEEE 802.11ax-2021 (Wi-Fi 6E, 6 GHz)), IEEE 802.15 WPAN standards, WWAN such as 3GPP or 3GPP2, Bluetooth standards, or similar wireless standards may be used. Wireless interface adapter120may connect to any combination of macro-cellular wireless connections including 2G, 2.5G, 3G, 4G, 5G or the like from one or more service providers. Utilization of radio frequency communication bands according to several example embodiments of the present disclosure may include bands used with the WLAN standards and WWAN carriers which may operate in both licensed and unlicensed spectrums. For example, both WLAN and WWAN may use the Unlicensed National Information Infrastructure (U-NII) band which typically operates in the ˜5 MHz frequency band such as 802.11 a/h/j/n/ac/ax (e.g., center frequencies between 5.170-7.125 GHz). WLAN, for example, may operate at a 2.4 GHz band, 5 GHz band, and/or a 6 GHz band according to, for example, Wi-Fi, Wi-Fi 6, or Wi-Fi 6E standards. WWAN may operate in a number of bands, some of which are proprietary but may include a wireless communication frequency band. For example, low-band 5G may operate at frequencies similar to 4G standards at 600-850 MHz. Mid-band 5G may operate at frequencies between 2.5 and 3.7 GHz. Additionally, high-band 5G frequencies may operate at 25 to 39 GHz and even higher. In additional examples, WWAN carrier licensed bands may operate at the new radio frequency range 1 (NRFR1), NFRF2, bands, and other known bands. Each of these frequencies used to communicate over the network134may be based on the radio access network (RAN) standards that implement, for example, eNodeB or gNodeB hardware connected to mobile phone networks (e.g., cellular networks) used to communicate with the information handling system100. In the example embodiment, mobile information handling system100may also include both unlicensed wireless RF communication capabilities as well as licensed wireless RF communication capabilities. For example, licensed wireless RF communication capabilities may be available via a subscriber carrier wireless service operating the cellular networks. With the licensed wireless RF communication capability, a WWAN RF front end (e.g., antenna front end125-1,125-2, or125-3circuits) of the information handling system100may operate on a licensed WWAN wireless radio with authorization for subscriber access to a wireless service provider on a carrier licensed frequency band.

The wireless interface adapter120can represent an add-in card, wireless network interface module that is integrated with a main board of the information handling system or integrated with another wireless network interface capability, or any combination thereof. In an embodiment the wireless interface adapter120may include one or more radio frequency subsystems130including transmitters and wireless controllers for connecting via a multitude of wireless links. In an example embodiment, an information handling system100may have an antenna system transmitter for 5G small cell WWAN, Wi-Fi WLAN or WiGig connectivity and one or more additional antenna system transmitters for macro-cellular communication. The RF subsystems130-1,130-2,130-3include wireless controllers to manage authentication, connectivity, communications, power levels for transmission, buffering, error correction, baseband processing, and other functions of the wireless interface adapter120.

The information handling system100may also, via the RF subsystems130-1,130-2,130-3of the wireless interface adapters120, measure various metrics such as system operation and connection metrics that relate to wireless communication by the information handling system100and provide that data as input data for an antenna selection algorithm164as described in the present disclosure. For example, the antenna controller140and RF subsystems130-1,130-2,130-3may manage detecting and measuring received signal strength levels, bit error rates (BER), signal to noise ratios, latencies, jitter, application telemetry data, specific absorption rate (SAR) data, and other metrics relating to signal quality and strength of any of a plurality of communication networks made available to the information handling system100. Some metrics relating to signal quality and strength of a wireless connection to a communication network may include a received signal strength indicator (RSSI). Additionally, the antenna controller140and radio frequency subsystem130may manage detecting which communication networks are available to the information handling system100to be operatively coupled to. In an embodiment, the detecting of communication networks available to the information handling system100may be accomplished using an out-of-band (OOB) communication to each of these networks. The antenna controller140may operate a sideband communication to each of the RF subsystems130-1,130-2,130-3to discover any potential network status and telemetry data from those radio systems. In another example embodiment, the information handling system100may communicate with a backend server or other server via this sideband communication establishing an OOB communication on at least one network (e.g., Wi-Fi) to obtain this data from one of an information handling system management system such as Dell Optimizer® for enterprise-administered wireless networks or a third-party service provider organization contracted to provide additional network-based data. For example, OOB communication with an information handling system management system may also discover telemetry data on one or more radio access networks for network data such as bandwidth, data congestion, channel availability, number of devices accessing access points or basestations, among others, as well as any other data related to the potential communication of the information handling system100with these radio access networks. Again, this remote information handling system management system may operate as a management and operations service provider administrator that is placed between information handling system (e.g., a host device) and a wireless network service provider that is the enterprise-owner of the wireless networks or third-party subscriber or available wireless networks.

During operation, the antenna controller140may also request and receive configuration data from, for example, an integrated sensor hub or individual device orientation and configuration sensors146, that describes the configuration and/or orientation of the information handling system100. In an example embodiment and in the context of the information handling system100being a 360-degree-type laptop, any number of sensors may be used to determine if the orientation the information handling system100is placed in is one of a tablet configuration, a dual tablet configuration, a laptop configuration, a tent mode configuration, a book configuration, as well as several other configurations described herein. The variety of sensors used to determine the configuration and/or orientation of the information handling system100may include, for example, a Hall effect sensor, a magnetometer, a proximity sensor, a hinge sensor, a light sensor, and a camera, among other sensors. In an embodiment, these variety of sensors may also include an accelerometer, a gyroscope, an orientation sensor in addition to these other sensors. In the embodiment, where an orientation sensor is used, a plurality of orientation sensors may be used to reference direction such as “up” or “north” in order to determine the orientation of the information handling system100. In an embodiment, this configuration data may form at least a part of the system configuration persona.

In an embodiment, the information handling system100may also gather peripheral telemetry data from an RF subsystem130-1,130-2,130-3operatively coupling one or more peripheral devices to the information handling system. In an embodiment, the RF subsystems130-1,130-2,130-3may be operatively coupled to peripheral telemetry data sensors166that describe which and what type of peripheral devices are operatively coupled to or couplable to the information handling system100. In an embodiment, the peripheral telemetry data is also descriptive of the connectivity requirements for the one or more peripheral devices such as which wireless communication protocol the peripheral device may communicate with the information handling system100. As described herein, the peripheral devices may include any one of the keyboard172, mouse170, video/graphic display110, stylus176, headset174, trackpad178among other peripheral devices that may be wirelessly couplable to the information handling system100. In an embodiment, this wireless peripheral status and telemetry data may form at least a part of the wireless ecosystem persona.

In an embodiment, the antenna controller140of the wireless interface adapter120may manage one or more RF subsystems130-1,130-2,130-3to manage transmission power levels which directly affect RF subsystems130-1,130-2,130-3power consumption as well as transmission power levels from the plurality of antennas148,150,152,154,156,158. The transmission power levels from the antennas148,150,152,154,156,158may be relevant to specific absorption rate (SAR) safety limitations for transmitting mobile information handling systems. To control and measure power consumption by the antennas148,150,152,154,156,158, the RF subsystems130-1,130-2,130-3may control and measure current and voltage power that is directed to operate one or more antennas148,150,152,154,156,158. Additional SAR data may be received via operation of a number of proximity sensors144located at or near each of the antennas148,150,152,154,156,158which may include SAR sensors. In this embodiment, the power levels provided to the antennas148,150,152,154,156,158may be compared to the data received by the proximity sensors144to determine, for example, these SAR safety limitations as well as determine whether, for example, a user's body part is absorbing this RF electromagnetic radiation. In an embodiment, this SAR data may form at least a part of the usage persona. This data associated with the usage persona may be provided to the antenna controller140executing the antenna selection algorithm164to determine the assignment of the plurality of antennas148,150,152,154,156,158to the or more peripheral devices and plurality of operating wireless links initiated by the RF subsystems130-1,130-2,130-3.

In an embodiment, the antenna controller140may also include device orientation and configuration sensors146. The device orientation and configuration sensors146may, upon execution by the processor102, receive input from any number of sensors and organize the data from that input in order to track the orientation, configuration, and/or location of the information handling system100. These sensors may include, for example, a temperature sensor, a pressure sensor, a Hall effect sensor, a magnetic sensor, an accelerometer, a magnetometer, a hinge sensor, a light sensor (e.g., ultraviolet light sensor, ambient light sensor), a camera, and a color sensor, among others. Each of these sensors may provide data to an integrated sensor hub which provides that data to the antenna controller140to be used as input to the antenna selection algorithm164. In an embodiment, this data related to the orientation, configuration, and/or location of the information handling system100forms part of the system configuration persona. In an embodiment, these sensors may be actively operating in order to describe the orientation, configuration, and location of the information handling system100at any given time and update the system configuration persona periodically.

The antenna controller140may also include a sideband serial messaging protocol142that, when executed by the antenna controller140, initiates the sideband communication with any of the RF subsystems130-1,130-2,130-3to establish an out-of-band (OOB) communication with at least one of the plurality of networks described herein. In an embodiment, the sideband communication may be initiated to establish any OOB wireless communication link with any wireless network apart from a concurrently initiated communication link. In an embodiment, the sideband communication link achieved via execution of the sideband serial messaging protocol142may allow the antenna controller140to determine which wireless networks are available to operatively couple the information handling system100to a wireless network as well as any system operation and connection metrics associated with those wireless networks. Again, because the system operation and connection metrics include wireless quality of service (QoS) data descriptive of a measured received signal strength level (RSSI), bit error rate (BER), signal to noise ratio (SNR), network beacon and enclosed information, latency, jitter, and other metrics relating to signal quality and strength of any of each of a plurality of communication networks, the data obtained by the antenna controller140may be used during execution of the antenna selection algorithm164to determine which wireless network to operatively couple the information handling system to. In an embodiment, this link status data and telemetry data may form at least a part of the link persona detected for the information handling system.

The information handling system100may further include a power management unit (PMU)118(a.k.a. a power supply unit (PSU)). The PMU118may manage the power provided to the components of the information handling system100such as the processor102, a cooling system, one or more drive units116, a graphical processing unit (GPU), a video/graphic display device or other input/output devices112, and other components that may require power when a power button has been actuated by a user. In an embodiment, the PMU118may monitor power levels and be electrically coupled to the information handling system100to provide this power and coupled to bus108to provide or receive data or instructions. The PMU118may regulate power from a power source such as a battery126or A/C power adapter128. In an embodiment, the battery126may be charged via the A/C power adapter128and provide power to the components of the information handling system100when A/C power from the A/C power adapter128is removed.

Information handling system100includes one or more of an operating system (OS)138, and basic input/output system (BIOS) firmware/software136or application programs that may be executable instructions124executed at any processor102and stored at one or more memory devices104,106, or116. BIOS firmware/software136functions to initialize information handling system100on power up, to launch an OS138, and to manage input and output interactions between the OS138and the other elements of information handling system100. In a particular embodiment, BIOS firmware/software136resides in memory104, and include machine-executable code that is executed by processor102to perform various functions of information handling system100as described herein. In another embodiment (not illustrated), application programs and BIOS firmware/software136reside in another storage medium of information handling system100. For example, application programs and BIOS firmware/software136can reside in drive116, in a ROM (not illustrated) associated with information handling system100, in an option-ROM (not illustrated) associated with various devices of information handling system100, in a storage system (not illustrated) associated with network channel of a wireless interface adapter120, in another storage medium of information handling system100, or a combination thereof. Executable code instructions124for application programs and BIOS firmware/software136can each be implemented as single programs, or as separate programs carrying out the various features as described herein.

During operation of the information handling system100, the processor102may cause the antenna controller140, via the RF subsystems130-1,130-2,130-3, to initiate a sideband communication link by executing the sideband serial messaging protocol142. In this embodiment, the sideband serial messaging protocol142may include any instructions executable by an embedded controller (EC), the processor102, or a combination thereof to establish an OOB communication link with a network to identify any potential communication link available to the information handling system100that operatively couples the information handling system100to any type of network described herein. In an embodiment, the antenna controller140may execute the sideband serial messaging protocol140to operatively couple the information handling system100to a Wi-Fi access point for OOB communications in order to harvest operating band data, channel data, along with other system operation and connection metrics associated with that Wi-Fi network and other available RAT networks from the information handling system management system such as Dell Optimizer® operating as a management and operations service provider administrator placed between the information handling system100and a wireless network service provider such as for an enterprise owned or third party provided wireless network. Additionally, or alternatively, the antenna controller140may execute the sideband serial messaging protocol140to operatively couple the information handling system100to another WLAN or WWAN access point such as the wireless access point160or base stations162within any network as described herein to establish these OOB communications in some other embodiments. In these embodiments, by operatively coupling the information handling system100to these wireless access points160and base stations162, the information handling system100may harvest system operation and connection metrics via OOB communications that define a link persona. This may be done for plural, available RAT networks and may be received by the information handling system from the information handling system management system such as Dell Optimizer®. Examples of these system operation and connection metrics used to define the link persona of the information handling system may include frequencies of the communication bands, bands used, channels used, concurrent WWAN and WLAN channels or other protocol channels, non-concurrent WWAN and WLAN channels or other protocol channels, idle metrics, disconnected states, signal strength metrics, and identification of radio access technology used to communicate with the network, networks may include those such as 4G, licensed-assisted access (LAA), 5G, Wi-Fi6, Wi-Fi6e, and may implement wire links utilizing Wi-Fi dual-band simultaneous (DBS) operation, uplink or downlink MIMO (e.g., 4×4 Wi-Fi MIMO or 4×4 cellular MIMO), a number of spatial streams, among other wireless link types for which metrics and operating characteristics may be measured. In this way, the antenna controller140may help to determine which wireless protocol (e.g., Bluetooth, Wi-Fi, other WLAN, or WWAN) is actively operating by the information handling system100along with what wireless protocols of the available wireless networks are available for the information handling system100. In an embodiment, these system operation and connection metrics defining the link persona may also include the wireless QoS data. As described herein, this data associated with the link persona of the information handling system may form part of the input the antenna controller140is provided during the execution of the antenna selection algorithm164described herein. The antenna controller140may then, based at least partially on this data associated with the link persona and other data described herein, switch an RF switch168-1,168-2,168-3associated with the antenna front end125-1,125-2,125-3circuits to engage an antenna element with an RF subsystem130-1,130-2,130-3operating a wireless protocol that increases data transmissions based on the system operation and connection metrics defined within the link persona. This may manage resources at the information handling system100using the on-board wireless resources in order to optimize the operation of the information handling system100operating within a wireless connectivity context while maintaining OOB communication used to dynamically distribute and optimize those resources should changes in, at least, that link persona be identified.

For example, output is provided by the execution of the antenna selection algorithm, a wireless connectivity context may be created. This wireless connectivity context may define which of the antennas132are to be operatively coupled to which RF subsystem130-1,30-2,130-3in order to optimize those antenna resources. This wireless connectivity context may have identified that Wi-Fi is not always be available for a mobile information handling system such as a laptop. If Wi-Fi is not available, an antenna controller140is directed, per the wireless connectivity context, to execute an RF switch168-1,168-2,168-3to enable one or more antenna elements to operate with a cellular wireless subsystem in an embodiment to enhance data bandwidth and wireless coverage as well as be operatively coupled to a Bluetooth device, in some embodiments, concurrently. For example, four antenna elements may be available to the cellular subsystem and provide for 4×4 MIMO connectivity. In this embodiment, at least one of the antenna elements may operate in a concurrent mode by communicating with a Bluetooth device using, for example a 2.4 GHz frequency band, as well as with a cellular network (or a WLAN network) using a 5 GHz frequency band. This allows the information handling system100to accommodate for, at least, the link persona the information handling system100is operating under and, along with a wireless ecosystem persona, a usage persona, and a system configuration persona, provide communications to one or more wireless network as well as with one or more peripheral devices used to allow the user to provide input to and receive output from the information handling system100.

In another embodiment, if Wi-Fi is detected as available or operational, the antenna controller may allocate one or more shared antennas via an RF switch168-1,168-2,168-3to the Wi-Fi wireless subsystem to enable Wi-Fi communications (e.g., 2×2 MIMO Wi-Fi communications). Remaining antennas may still provide for some portion of a cellular wireless subsystem communication (e.g., 2×2 MIMO cellular communications). The antenna elements (e.g., antennas148,150,152,154,156,158) may then effectively transmit communications signals depending on the wireless conditions detected and described in the link persona.

In an embodiment, the system operation and connection metrics that are defined in, at least, the link persona and wireless ecosystem persona, such as for coupled wireless peripherals, may be obtained by the antenna controller140via execution of a sideband serial messaging protocol140to the RF subsystems130-1,130-2,130-3. This system and operation and connection metrics described in the link persona and wireless ecosystem persona may be used as input to the antenna selection algorithm164along with the system configuration persona and usage persona. As input, these system operation and connection metrics may help to determine which of a plurality of antennas148,150,152,154,156,158to use in order to be used to operate the RF subsystems130-1,130-2,130-3at an optimizable wireless protocol to accommodate the detected personas of the information handling system100wireless connectivity context detected.

In addition to retrieving the system operation and connection metrics defined in the link persona, the antenna controller140may also obtain any proximity data (e.g., presence of humans or any detected SAR data) from a plurality of proximity sensors144. The proximity data obtained may form part of the usage persona described herein. In an embodiment, the retrieval of this proximity data may be done concurrently along with the retrieval of the other system operation and connection metrics described herein such as the link persona, the wireless ecosystem persona, and the system configuration persona. The proximity data is gathered using, in an embodiment, a SAR proximity sensor144associated with each antenna148,150,152,154,156,158formed within the information handling system100. Additionally, the transmission power levels (e.g., current and voltage) from the antennas132may be relevant to specific absorption rate (SAR) safety limitations for transmitting mobile information handling systems and may be used to develop the SAR data provided to the antenna controller140. This SAR data may also be used by the antenna controller140executing the antenna selection algorithm164as input to the antenna selection algorithm164in order to help determine which of a plurality of antennas148,150,152,154,156,158to use in order to operate the information handling system100under a wireless protocol for the detected information handling system100wireless connectivity context.

In addition to retrieving the proximity data, the antenna controller140may also obtain any RSSI data or other wireless signal quality metrics used to form part of the usage persona. In one embodiment, RSSI data may be retrieved from, for example, an intermediate-frequency (IF) amplifier used by the wireless interface adapter120to raise or lower signal levels at the RF subsystems130-1,130-2,130-3by increasing or decreasing the power applied to each of the antennas148,150,152,154,156,158. If and when the RSSI drops, for example, the proximity data may also be cross-referenced to determine whether the drop in transmission is due to the presence of a human body or a drop in power otherwise provided to or received by any given antenna148,150,152,154,156,158. This RSSI data or other wireless signal quality metrics may form part of the usage persona as described herein.

In an embodiment, the antenna controller140may also obtain configuration data descriptive of a configuration of the information handling system100. In an embodiment, this configuration data may form part of the system configuration persona as described herein. In order to do this, the information handling system100may include a number of additional sensors include, for example, a Hall effect sensor. The Hall effect sensor may be placed at any location within the chassis of the information handling system100to detect the position of the individual parts of the information handling system100relative to each other. In a specific embodiment where the information handling system100is a laptop-type information handling system100, the Hall effect sensor may be placed in one or more of a display portion or base portions of the information handling system100. In this embodiment, the Hall effect sensor, in combination with any orientation sensor, gyroscope, and/or accelerometer, may detect when the display portion is moved away from a top surface of a based portion, a relative position of the display portion to the base portion, and/or when a back side of the display portion is placed against a bottom portion of the base portion of the information handling system100. As described herein, this allows the Hall effect sensor and other sensors to detect whether the laptop-type information handling system100is placed in an open configuration, a closed configuration, a tablet configuration, a dual tablet configuration, a laptop configuration, a tent mode configuration, a book configuration, as well as several other configurations described herein. The Hall effect sensor and other sensors may be similarly used in a dual screen-type information handling system100in order to detect the relative positions of each of the screens. Again, any data obtained by the Hall effect sensor and other sensors is presented to the antenna controller140for the antenna controller140to interpret and provide that orientation data as input to the antenna selection algorithm164as described herein.

In an embodiment, a magnetometer may operate as an orientation sensor and may be used to measure the earth's magnetic field at any location in order to detect an orientation of the information handling system100relative to that magnetic field in order to further define the system persona. In a specific embodiment, the magnetometer may be a three-axis magnetometer that eliminates the sensitivity to the way in which the information handling system100is held or positioned. Similarly, a gyroscope sensor may be used to measure any changes in direction along an x-axis, a y-axis, and a z-axis according to a Cartesian coordinate system. Again, any data obtained by the magnetometer is presented to the antenna controller140for the antenna controller140to interpret and provide as input to the antenna selection algorithm164as described herein.

When the peripheral telemetry data, system operation and connection metrics, and configuration data are received by the antenna controller140, the antenna controller140may execute the antenna selection algorithm164in order to identify which among a plurality of transceiving antennas148,150,152,154,156,158are to be associated with any given RF subsystem130-1,130-2,130-3in order to communicate with a network using one or more determined wireless protocols. As such, the information handling system100may periodically monitor for changes in the peripheral telemetry data, system operation and connection metrics, and configuration data in order to determine if and when to switch any number of antennas148,150,152,154,156,158form being operatively coupled to an initial RF subsystem130-1,130-2,130-3to a different RF subsystem130-1,130-2,130-3for the information handling system100to transceive data across any type of network to accommodate the above persona for the information handling system100connectivity context for the antenna selection algorithm.

In an embodiment, the antenna selection algorithm164may include an artificial neural network, Bayesian network, decision trees, regression analysis, among other machine learning service algorithms that may be used to model the persona within which the information handling system100operates and provide a closed loop system that can dynamically distribute and optimize resources (e.g., RF subsystems130-1,130-2,130-3and antennas148,150,152,154,156,158) by providing feedback or output that optimizes the connectivity of the information handling system100to the various wireless networks based on the detected data of the usage persona, the system configuration persona, the wireless ecosystem persona, the link persona, and other aspects of the information handling system100wireless connectivity context for antenna control. In this embodiment, the antenna selection algorithm164applies a machine learning methodology to determine correlations of the influencing factors including peripheral telemetry data, system operation and connection metrics, configuration data, operating software applications, and other metrics from personas in embodiments described herein and detect changes to any of these influencing factors to suggest or automatically apply changes to the assignment of any of the antennas148,150,152,154,156,158to any of the RF subsystems130-1,130-2,130-3. In some aspects, suggested predictive adjustments or notice of automatic predictive adjustments may be confirmed or declined by the user. In an embodiment, the antenna selection algorithm164is executed on a processor102. Additionally, or alternatively, the antenna selection algorithm164is executed remotely on an information handling system management system such as Dell Optimizer® and antenna control may be provided remotely to the information handling system100via an OOB communication or on other processing logic (e.g., an embedded controller) in whole or in part available at or accessible to the information handling system100. In an embodiment, the suggested adjustments may be provided to the antenna controller140. Based on these selected adjustments, the antenna controller140may send signals to the RF switches168-1,168-2,168-3to cause the suggested assignments of the antennas148,150,152,154,156,158to the suggested RF subsystems130-1,130-2,130-3in order to increase the optimized use of the transceiving antennas148,150,152,154,156,158while the information handling system100operates within the detected persona.

In an embodiment, the antenna selection algorithm164may include a look-up table. This look-up table may include a number of triggers that may be used to define the peripheral telemetry data, the system operation and connection metrics, and configuration data defined by the usage persona, the system persona, the wireless ecosystem persona, the link persona, and other aspects of the information handling system100wireless connectivity context for antenna control. The look-up table may also include a connectivity resource mapping defining an antenna assignment as output based on the peripheral telemetry data, the system operation and connection metrics, and configuration data as described. This output may be referred to herein as a wireless connectivity context. The look up table includes, as inputs, the usage persona, the system persona, the wireless ecosystem persona, the link persona, and other aspects of the information handling system100wireless connectivity context. These inputs may be treated as data points that are correlated with a wireless connectivity context of the information handling system100at that point in time. The output of the look-up table includes the correlation of this context into an assignment and operative coupling of the various antennas132to specific RF subsystems130-1,130-2,130-3and the operating frequencies of each of those antennas132. Multiple sets out of outputs defining the wireless connectivity contexts may be presented in the table as “scenarios.” Where the antenna selection algorithm164is a machine learning service algorithm, these inputs may be used to correlate the various inputs and provide, as output to dynamically distribute and optimize resources (e.g., RF subsystems130-1,130-2,130-3and antennas148,150,152,154,156,158,FIG.1) by providing feedback or output that optimizes the connectivity of the information handling system to the various wireless networks and peripheral devices (e.g., Bluetooth devices). In an embodiment, both the machine learning service algorithm and look-up table may be used with different scenarios being added to the look-up table based on the classifier of the machine learning algorithm adjusting the table based on its past output performance feedback.

In an embodiment, where the information handling includes six antennas, such a look-up table may look like the following table (Table 1):

Although, Table 1 shows two scenarios, also referred to as wireless connectivity contexts that may be determined for detected persona inputs according to embodiments herein, it is appreciated that more than two scenarios may be presented or maintained on such a look-up table. As such, it is appreciated that more rows may be added to Table 1 as additional and different inputs (e.g., usage persona, system configuration persona, wireless ecosystem persona, the link persona, and other aspects of the information handling system100wireless connectivity context for antenna control) are presented to the antenna selection algorithm164and used to determine how to assign the antennas132to the RF subsystems130-1,130-2,130-3.

In this example look-up table, two scenarios are presented. However, these scenarios are meant to be only two examples of several potential embodiments describing a persona under which the information handling system100may operate and is not meant to limit the present disclosure to these specific scenarios. In scenario #1 (third row, Table 1), system and usage persona data include a first column that describes system configuration persona data descriptive of, at least, some of the data associated with the configuration data described herein. In scenario #1, this system configuration persona data includes an indication that the lid of the information handling system100is open indicating its configuration. In this context, the information handling system100is a laptop-type information handling system with the lid or a part of the chassis that includes a video display device110in an open state relative to a base chassis. As described, this specific orientation data of the system configuration data may be detected using any number of sensors including a Hall effect sensor as described herein. In embodiments herein, when the lid or display chassis is in an open state on a laptop-type information handling system for example, the user can view the display while interacting with the keyboard placed within the base chassis. When the lid or display is in a closed state on a laptop-type information handling system, the display is not viewable due to the display chassis being closed against the base chassis. It is appreciated that in the closed position, the user may still interact with operation of the information handling system when, for example, the information handling system100is docked at a docking station and an external monitor is used as an I/O device. Further, in other embodiments, the information handling system100may operate in a closed orientation to conduct various wireless activity such as background functions, OOB communications, or Bluetooth/Wi-Fi/5G communications with other peripherals such as virtual reality headsets or the like. It is further appreciated that other configurations of the information handling system100apart from a closed and open position are anticipated in the present specification. As described, these other configurations include tablet configuration where the information handling system is in a tablet form or where the base portion of the information handling system is made to flip behind the display portion. In a dual tablet configuration, the information handling system100may be made of a base portion that includes a separate base chassis display device along with the display device of the display portion of the information handling system or a single foldable display may span both chassis of a dual-display information handling system100. In this dual tablet configuration, the base portion and display portion are laid open to reveal both display devices or an entire foldable display to the user. In a laptop configuration, the information handling system may have the base portion on a table or on the user's lap with the display portion upright and viewable to the user. In a tent mode configuration, the display portion may be viewable to the user with the base portion in an orientation to prop up the display portion on a table, for example. In a book configuration, the base portion and display portion of the information handling system may be opened up to the user and the system rotated like the user has a book open. Several other configurations described herein may also be used. It is appreciated that these individual configurations may affect the transmission and reception capabilities of any of the antennas148,150,152,154,156,158within the information handling system100due to their placement within the chassis of the information handling system100. For example, where some of the antennas148,150,152,154,156,158are placed in the base portion of a laptop-type information handling system100, placing the laptop on a user's lap may affect the ability of those antennas148,150,152,154,156,158to transmit or receive data. This may be evidenced by the resulting SAR data or RSSI data as indicated in the second column of Table 1.

Scenario #1 also has a third column describing the usage persona of the information handling system100. This usage persona column may include data related to system operation and connection metrics and specifically whether, in this example, human presence is detected near the information handling system100. Again, this data may be obtained from a number of sensors including a proximity sensor and/or a SAR detector.

Scenario #1 also has a fourth column describing the wireless ecosystem persona that includes, among other potential data, the peripheral telemetry data. Peripheral devices are used by a user to interact with the information handling system100and to provide output to the user or that the user implements to provide input to the information handling system100. These peripheral devices may include the I/O devices112described herein including a keyboard172, a mouse170, a video/graphic display110, a stylus176, a headset174(audio or virtual reality (VR)), and a trackpad178. In the first scenario, a headset174operating under a Wi-Fi wireless protocol and a mouse170operating under a Bluetooth® (“BT”) wireless protocol is indicated as being present within the persona context. Because a user may interact with, for example, an online gaming application being executed on the information handling system100, the headset174may be used by the user to interact verbally with other online users and hear gameplay sounds or may be a VR headset. The mouse170may also be used by a user during the execution of a gaming application to make selections during gameplay.

Scenario #1 also has a fifth column describing the link persona describing the data transmission requirements to be used under which the RF subsystems130-1,130-2,130-3currently operating. In the example presented in scenario #1, the link persona indicates that the host Wi-Fi or the Wi-Fi RF subsystem (e.g.,130-1,130-2, or130-3) is operating under very high data throughput (VHT) and a concurrent dual-band (CDB) mode. The VHT mode may be a result of the type of application being executed on the information handling system100such as the audio-visual streaming application or online gaming application described herein both of which have a relatively higher transception of data across a network than, for example, an email application. The CDB (aka: simultaneous dual band), in relation to the operation of any antenna132, may be the operation of those antennas at two separate networks or devices simultaneously using both 2.4- and 5-GHz frequency bands, for example. This, along with potentially doubling the available bandwidth, allows for more reliable network connections to be established. The link persona column may also include other system operation and connection metrics that include application telemetry data descriptive of an application being executed on the information handling system100. For example, the system operation and connection metrics may include data describing that an audio/video streaming application is being executed that indicates that a relatively higher data transmission bandwidth low latency (avoid stalls) is necessary to properly execute that application in comparison to, for example, the execution of an email application. Similarly, an online gaming application may also be an example application that indicates that data transmissions may be high during execution and the system operation and connection metrics presented in the third column describing this usage context. It is therefore appreciated that the data presented in any of the columns under the “System and Usage Personas” column shown in Table 1 may include more or less data used as input to the antenna selection algorithm164as described herein. Still further, in an embodiment, the link persona may also include data describing latency, packet loss, network congestion, and prediction error either detectable at the radios of the information handling system or via the sideband communications establishing the OOB communication with an information handling system management system such as Dell Optimizer®. Still further, the link persona may also include data describing total available bandwidth on any given network. Again, this data may be provided via the sideband communications establishing the OOB communication with an information handling system management system and may describe what network slices are provided for the various data transmission (e.g., audio data, video data, web traffic, email data, and file transfer data).

As a result of the inputs into the antenna selection algorithm164such as the system configuration persona, the usage persona, the wireless ecosystem persona, and the link persona (e.g., examples shown in columns 2-5 of Table 1), the antennas148,150,152,154,156,158may be assigned to specific RF subsystems130-1,130-2,130-3according to Table 1 thereby mapping the antenna resources of the information handling system100. Continuing with scenario #1 in Table 1, a WWAN radio (e.g., second RF subsystem130-2with its second RF front end125-2) may have four antennas, a first antenna148, a second antenna150, a third antenna152, and fourth antenna154, to transceive data using a specific wireless protocol. Although these four antennas148,150,152,154may be operatively coupled to a WWAN radio such as a cellular RF subsystem, one of these antennas (e.g., a second antenna150) may be switched from being operatively coupled to the cellular RF subsystem to an out-of-band (OOB) Wi-Fi RF subsystem (e.g., the third RF subsystem130-3with its third RF front end125-3) controlled by an embedded controller (EC). Moreover, one or more antennas132may be designated for concurrent Bluetooth operation depending on the detected wireless connectivity context of the plural personas for the information handling system100. This may be done according to the output presented to the antenna controller140after executing the antenna selection algorithm164. According to this output, the first antenna148may be operatively coupled to the second RF subsystem130-2via the second RF front end125-2to scan for cellular network connectivity. The second antenna150(as indicated in the 7thcolumn, Scenario #1, Table 1) may not be connected to the second RF subsystem130-2and, instead operatively coupled to the third RF subsystem130-3to scan for the OOB provisioning and receiving of the system operation and connection metrics as described herein. The third antenna152may be operatively coupled to the first RF subsystem130-1via the first RF front end125-1to operate under a 5 GHz frequency. The fourth antenna154is also operatively coupled to the first RF subsystem130-1via the first RF front end125-1and used to operate under a 5 GHz frequency. This is done in order to optimize the Wi-Fi connectivity per the radio context presented in this scenario (column 5, scenario #1, Table 1) that indicates that a very high throughput (VHT) is necessary to transceive the data to and from the information handling system100. The antenna controller140may assign these antennas148,150,152,154to these RF subsystems via use of one or more switches168-1,168-2, and168-3as described in more detail in connection withFIG.3herein.

Table 1 also shows two antennas (e.g., a fifth antenna156and a sixth antenna158) may be associated with a host (e.g., information handling system100) Wi-Fi Radio such as a Wi-F-RF subsystem (e.g., first RF subsystem130-1with its first RF front end125-1). In scenario #1, the fifth antenna156is switched from the first RF subsystem130-1to be used by the second RF subsystem130-2via a first switch168-1. This allows the second RF subsystem130-2to operate under a concurrent dual band (e.g., column 5, scenario #1, Table 1) at, for example, 5 GHz and 2.4 GHz. This allows the fifth antenna156to be concurrently, operatively coupled to a Wi-Fi protocol network as well as, in this example scenario #1, a peripheral device such as a mouse (column 12, scenario #1, Table 1) under Bluetooth. In an embodiment, the sixth antenna158may be operatively coupled, at 2.4 GHz, to another peripheral device such as a headset via Bluetooth communication.

The arrangement of the antennas148,150,152,154,156,158to be operatively coupled to a specific RF subsystem130-1,130-2,130-3via manipulation of one or more switches168-1,168-2,168-3allows for the antenna controller140to prioritize for specific wireless protocols based on the received peripheral telemetry data, system operation and connection metrics, and configuration data. By using this data to assign the antennas148,150,152,154,156,158in this manner the information handling system100may intelligently manage resources, in a closed loop fashion, to distribute wireless resources based on the persona in which the information handling system100is currently working under. This allows for the selection of the best antennas148,150,152,154,156,158to use for connection to a network and any peripheral device at any given time. In this manner the information handling system100can dynamically distribute and optimize these wireless resources by defining a usage persona, system configuration persona, wireless ecosystem persona, and link persona. Through continual closed loop feedback, this data may be used to optimize those wireless resources accordingly. Table 1 also shows a second scenario where the switches168-1,168-2, and168-3may be accessed by the antenna controller140to optimize the use of those wireless resources based on the input (e.g., columns 2-5, scenario #2, Table 1) according to a new persona the information handling system100has detected to be within.

Table 1 also shows a second scenario, Scenario #2. Like the first scenario, scenario #2 includes system configuration persona data indicating that the information handling system100is currently in a tablet configuration. The usage persona data indicates that there is human proximity next to at least one antenna132. The wireless ecosystem persona data indicates that no peripheral device is currently couplable to the information handling system100. Additionally, the link persona data indicates that the host Wi-Fi or the Wi-Fi RF subsystem (e.g.,130-1,130-2, or130-3) is operating under very high data throughput (VHT) and a concurrent dual-band (CDB) mode with some of the antennas operating under a 4×4 MIMO LTE protocol. Again, as output, the first antenna148is connected to the second RF subsystem130-2. The second antenna150is also operatively coupled to the second RF subsystem130-2under a MIMO configuration. The third antenna152is indicated as not being connected but instead is used by the third RF subsystem130-3to scan for a wireless connection. The fourth antenna154is connected to a Wi-Fi network using a 5 GHz frequency. The fifth antenna156and sixth antenna158are also connected to a Wi-Fi network at using a 5 GHz frequency.

FIG.1also shows that the information handling system100may be operatively coupled to a wireless network134. In an embodiment, the wireless network134may have a wireless mesh architecture in accordance with mesh networks described by the wireless data communications standards or similar standards in some embodiments but not necessarily in all embodiments. The wireless interface adapter120may also connect to the external network via a WPAN, WLAN, WWAN or similar wireless switched Ethernet connection in some embodiments. The wireless data communication standards set forth protocols for communications and routing via access points, as well as protocols for a variety of other operations. Other operations may include handoff of client devices moving between nodes, self-organizing of routing operations, or self-healing architectures in case of interruption.

In an embodiment, the information handling system100may be operatively coupled to a network using one or more of the antennas148,150,152,154,156,158using a wireless protocol based on the following example table, Table 2:

FIG.2illustrates a network200that can include one or more information handling systems210,220,230. The information handling systems210,220,230shown inFIG.2may be similar to the information handling system100described in connection withFIG.1. In a particular embodiment, network200includes networked mobile information handling systems210,220, and230, wireless network access points, and multiple wireless connection link options. A variety of additional computing resources of network200may include client mobile information handling systems, data processing servers, network storage devices, local and wide area networks, or other resources as needed or desired. As partially depicted, information handling systems210,220,230may be a laptop computer, tablet computer, 360-degree convertible systems, wearable computing devices, or a smart phone device. These mobile information handling systems210,220, and230, may access a wireless local network240, or they may access a macro-cellular network250. For example, the wireless local network240may be the wireless local area network (WLAN), a wireless personal area network (WPAN), or a wireless wide area network (WWAN). In an example embodiment, LTE-LAA WWAN may operate with a small-cell WWAN wireless access point option.

Since WPAN or Wi-Fi Direct Connection248and WWAN networks can functionally operate similar to WLANs, they may be considered as wireless local area networks (WLANs) for purposes herein. Components of a WLAN may be connected by wireline or Ethernet connections to a wider external network such as a voice and packet core280. For example, wireless network access points (e.g.,160FIG.1) or base stations (e.g.,162,FIG.1) may be connected to a wireless network controller and an Ethernet switch. Wireless communications across wireless local network240may be via standard protocols such as IEEE 802.11 Wi-Fi, IEEE 802.11ad WiGig, IEEE 802.15 WPAN, IEEE 802.11ax-2021, (e.g., Wi-Fi 6 and 6E, 6 GHz technologies), or emerging 5G small cell WWAN communications such as gNodeB, eNodeB, or similar wireless network protocols and access points. Alternatively, other available wireless links within network200may include macro-cellular connections250via one or more service providers260and270. As described herein, a plurality of antennas may be operatively coupled to any of the macro-cellular connections250via one or more service providers260and270or to the wireless local area networks (WLANs) selectively based on the SAR data, RSSI data, configuration data, system operation and connection metrics, peripheral telemetry data, and antenna mounting locations (e.g., spatial locations of antennas within the information handling system) associated with each information handling systems210,220,230as described herein. Service provider macro-cellular connections may include 2G standards such as GSM, 2.5G standards such as GSM EDGE and GPRS, 3G standards such as W-CDMA/UMTS and CDMA 2000, 4G standards, or emerging 5G standards including WiMAX, LTE, and LTE Advanced, LTE-LAA, small cell WWAN, and the like.

Wireless local network240and macro-cellular network250may include a variety of licensed, unlicensed or shared communication frequency bands as well as a variety of wireless protocol technologies ranging from those operating in macrocells, small cells, picocells, or femtocells. As described herein, utilization of RF communication bands according to several example embodiments of the present disclosure may include bands used with the WLAN standards and WWAN carriers which may operate in both licensed and unlicensed spectrums. For example, both WLAN and WWAN may use the Unlicensed National Information Infrastructure (U-NII) band which typically operates in the ˜5 MHz frequency band such as 802.11 a/h/j/n/ac/ax (e.g., center frequencies between 5.170-7.125 GHz). WLAN, for example, may operate at a 2.4 GHz band, 5 GHz band, and/or a 6 GHz band according to, for example, Wi-Fi, Wi-Fi 6, or Wi-Fi 6E standards. WWAN may operate in a number of bands, some of which are proprietary but may include a wireless communication frequency band. For example, low-band 5G may operate at frequencies similar to 4G standards at 600-850 MHz. Mid-band 5G may operate at frequencies between 2.5 and 3.7 GHz. Additionally, high-band 5G frequencies may operate at 25 to 39 GHz and even higher. In additional examples, WWAN carrier licensed bands may operate at the new radio frequency range 1 (NRFR1), NFRF2, bands, and other known bands. Each of these frequencies used to communicate over the network134may be based on the radio access network (RAN) standards that implement, for example, eNodeB or gNodeB hardware connected to mobile phone networks (e.g., cellular networks) used to communicate with the information handling system100. In the example embodiment, mobile information handling system100may also include both unlicensed wireless RF communication capabilities as well as licensed wireless RF communication capabilities. For example, licensed wireless RF communication capabilities may be available via a subscriber carrier wireless service operating the cellular networks. With the licensed wireless RF communication capability, an WWAN RF front end of the information handling system100may operate on a licensed WWAN wireless radio with authorization for subscriber access to a wireless service provider on a carrier licensed frequency band. WLAN such as Wi-Fi (e.g., Wi-Fi 6) may be unlicensed.

In some embodiments according to the present disclosure, a networked mobile information handling system210,220, or230may have a plurality of wireless network interface systems capable of transmitting simultaneously within a shared communication frequency band. That communication within a shared communication frequency band may be sourced from different protocols on parallel wireless network interface systems or from a single wireless network interface system capable of transmitting and receiving from multiple protocols. Similarly, a single antenna or the plurality of antennas in each information handling system210,220,230may be used on each of the wireless communication devices such as according to embodiments herein and may be suited to plural RF bands. Example competing protocols may be local wireless network access protocols such as Wi-Fi/WLAN, WiGig, and small cell WWAN in an unlicensed, shared communication frequency band. Example communication frequency bands may include unlicensed 5 GHz frequency bands or 3.5 GHz conditional shared communication frequency bands under FCC Part96. Wi-Fi ISM frequency bands may be subject to sharing include 2.4 GHz, 60 GHz, 900 MHz or similar bands as understood by those of skill in the art. Within local portion of wireless network250access points for Wi-Fi or WiGig as well as small cell WWAN connectivity may be available in emerging 5G technology. This may create situations where a plurality of antenna systems are operating on a mobile information handling system210,220or230via concurrent communication wireless links on both WLAN and WWAN radios and antenna systems. In some embodiments, concurrent wireless links may operate within the same, adjacent, or otherwise interfering communication frequency bands and may be required to utilize spaced antennas. The antenna may be a transmitting antenna that includes high-band, medium-band, low-band, and unlicensed band transmitting antennas in embodiments herein. The antenna may cooperate with other antennas in a N×N MIMO array configuration according to the embodiments described herein. Alternatively, embodiments may include a single transceiving antennas capable of receiving and transmitting, and/or more than one transceiving antennas. Each of the antennas included in the information handling system100in an embodiment may be subject to the FCC regulations on specific absorption rate (SAR).

The voice and packet core network280shown inFIG.2may contain externally accessible computing resources and connect to a remote data center286. The voice and packet core network280may contain multiple intermediate web servers or other locations with accessible data (not shown). The voice and packet core network280may also connect to other wireless networks similar to240or250and additional mobile information handling systems such as210,220,230or similar connected to those additional wireless networks. Connection282between the wireless network240and remote data center286or connection to other additional wireless networks may be via Ethernet or another similar connection to the world-wide-web, a WAN, a LAN, another WLAN, or other network structure. Such a connection282may be made via a WLAN access point/Ethernet switch to the external network and be a backhaul connection. The access point may be connected to one or more wireless access points in the WLAN before connecting directly to a mobile information handling system or may connect directly to one or more mobile information handling systems210,220, and230. Alternatively, mobile information handling systems210,220, and230may connect to the external network via base station locations at service providers such as260and270. These service provider locations may be network connected via backhaul connectivity through the voice and packet core network280.

Remote data centers286may include web servers or resources within a cloud environment that operate via the voice and packet core280or other wider internet connectivity. For example, remote data centers can include additional information handling systems, data processing servers, network storage devices, local and wide area networks, or other resources as needed or desired. Having such remote capabilities may permit fewer resources to be maintained at the mobile information handling systems210,220, and230allowing streamlining and efficiency within those devices. Similarly, remote data center permits fewer resources to be maintained in other parts of network200. In an example embodiment, the mobile information handling systems210,220, and230may communicate with a backend server such as the remote data center286or other server via OOB on at least one network (e.g., Wi-Fi) to obtain this data from one of an information handling system management system such as Dell Optimizer® or a third-party service provider organization contracted to provide this data. Again, this remote information handling system management system may operate as a management and operations service provider administrator that is placed between information handling system (e.g., a host device) and a wireless network service provider such as for an enterprise owned or third party provided wireless network. The data requested by the mobile information handling systems210,220, and230from the remote data center286may include any data associated with the usage persona, the system configuration persona, the wireless ecosystem persona, the link persona described herein and specifically network data for all wireless networks managed by the remote data center286.

Although215,225, and235are shown connecting wireless adapters of mobile information handling systems210,220, and230to wireless networks240or250, a variety of wireless links are contemplated. Wireless communication may link through a wireless access point (Wi-Fi or WiGig), through unlicensed WWAN small cell base stations such as in network240or through a service provider tower and base stations such as that shown with service provider A260or service provider B270and in network250. In other aspects, mobile information handling systems210,220, and230may communicate intra-device via248when one or more of the mobile information handling systems210,220, and230are set to act as an access point or even potentially an WWAN connection via small cell communication on licensed or unlicensed WWAN connections. For example, one of mobile information handling systems210,220, and230may serve as a Wi-Fi hotspot in an embodiment. Concurrent wireless links to information handling systems210,220, and230may be connected via any access points including other mobile information handling systems as illustrated inFIG.2.

FIG.3is a block diagram illustrating an information handling system300for increasing transceiving coverage based on the switched antennas348,350,352,354,356,358among a plurality of radio frequency (RF) subsystems330-1,330-2,330-3described herein according to an embodiment of the present disclosure. In this embodiment, the information handling system300may include similar components as those described in connection withFIG.1such as a processor, a PMU, a BIOS, an OS, various input/output devices, among other components.

The information handling system300may include an antenna controller340operatively coupled to, in this embodiment, six different antennas348,350,352,354,356,358. In the embodiments, a first antenna348, a second antenna350, a third antenna352, a fourth antenna354, a fifth antenna356, and a sixth antenna358may each be associated with its own proximity sensor344-1,344-2,344-3,344-4,344-5,344-6. The proximity sensors344-1,344-2,344-3,344-4,344-5,344-6associated with each of these antennas348,350,352,354,356,358are used to determine a proximity of a user or other human by the information handling system100and, more particularly, by one of the antennas348,350,352,354,356,358. In an embodiment, the proximity sensors344-1,344-2,344-3,344-4,344-5,344-6may be or include a specific absorption rate (SAR) sensor. A SAR sensor may be used to provide to a proximity sensor hub394data describing the location of a user's body near an antenna348,350,352,354,356,358. The SAR sensor may determine proximity data used to extrapolate if and to what level the user's body is absorbing RF electromagnetic radiation emitted from or directed to any of the antennas348,350,352,354,356,358for safety considerations and, also, affecting the ability of the antennas348,350,352,354,356,358to transmit or receive data.

In the embodiment shown inFIG.3, the antenna controller340is associated with a number of RF subsystems330-1,330-2,330-3. A Wi-Fi/Bluetooth RF subsystem330-1may include any circuitry such as front ends, modems, protocol modules, amplifiers, filters, and tuners, among others that interfaces with antenna systems including each of the third antenna253, fourth antenna354, fifth antenna356, and sixth antenna358and the antenna controller340. The Wi-Fi/Bluetooth RF subsystem330-1may also include a number of ports used to dynamically and operatively couple the third antenna253, fourth antenna354, fifth antenna356, and/or sixth antenna358to the Wi-Fi/Bluetooth RF subsystem330-1in a wireless front end with switching capabilities. The Wi-Fi/Bluetooth RF subsystem330-1may be part of the antenna controller340or may be separate circuits, such as integrated circuits on a wireless adapter in various embodiments.

The antenna controller340may also be associated with and operatively coupled to a cellular RF subsystem330-2. A cellular RF subsystem330-2may include any circuitry such as front ends, modems, protocol modules, amplifiers, filters, and tuners, among others that interfaces with antenna systems including each of the first antenna348, second antenna350, third antenna253, and fourth antenna354along with the antenna controller340. The cellular RF subsystem330-2may also include a number of ports used to dynamically and operatively couple the first antenna348, second antenna350, third antenna253, and fourth antenna354to the cellular RF subsystem330-2via a switchable wireless front end. The cellular RF subsystem330-2may be part of the antenna controller340or may be separate circuits, such as integrated circuits on a wireless adapter in various embodiments.

The antenna controller340may also be associated with and operatively coupled to a OOB W-F RF subsystem and embedded controller (EC)330-3. A OOB W-F RF subsystem and EC330-3may include any circuitry such as front ends, modems, protocol modules, amplifiers, filters, and tuners, among others that interfaces with antenna systems including each of the first antenna348and fourth antenna354along with the antenna controller340. The OOB W-F RF subsystem and EC330-3may also include a number of ports used to dynamically and operatively couple the first antenna348and fourth antenna354to the OOB W-F RF subsystem and EC330-3via a switchable wireless front end. The OOB W-F RF subsystem and EC330-3may be part of the antenna controller340or may be separate circuits, such as integrated circuits on a wireless adapter in various embodiments.

In the embodiments described herein, the Wi-Fi/Bluetooth RF subsystem330-1along with the cellular RF subsystem330-2and OOB Wi-Fi RF subsystem330-3may help to provide an oscillation current to be passed to these antennas to propagate a signal from the antennas at a specific frequency and under a particular wireless protocol (e.g., Bluetooth, Wi-Fi, other WLAN protocol, or WWAN protocol). The RF subsystems330-1,330-2,330-3and the antenna controller340are operatively coupled to one or more switches368-1,368-2,368-3and the antennas348,350,352,354,356,358. In this embodiment, the switches368-1,368-2,368-3are one of a double pole, double throw (DPDT) switch or triple pole, double throw (TPDT) switches. In an embodiment, the first switch368-1is a DPDT switch while the second switch368-2and third switch368-3may be TPDT switch. These switches368-1,368-2,368-3, and specifically the first switch368-1and second switch368-2in this exemplary embodiment, may be multiple port switches that allow the Wi-Fi/Bluetooth RF subsystem330-1to be operatively coupled to any of the third antenna253, fourth antenna354, fifth antenna356, and sixth antenna358. These switches368-1,368-2,368-3also allow the cellular RF subsystem330-2to be operatively coupled to the first antenna348, second antenna350, third antenna253, fourth antenna354, fifth antenna356, or sixth antenna358. In an embodiment, the switches368-1,368-2,368-3may operatively couple the RF subsystems330-1,330-2,330-3and antenna controller340to the antennas348,350,352,354,356,358in order to allow the antennas to be operatively and dynamically coupled to any given RF subsystems330-1,330-2,330-3based on the output from the execution of the antenna selection algorithm by the antenna controller340as described herein.

Again, in order to make a decision regarding which of the antennas348,350,352,354,356,358are to be operatively coupled to an RF subsystem330-1,330-2,330-3, the antenna controller340may receive usage persona, the system configuration persona, the wireless ecosystem persona, the link persona data (e.g., peripheral telemetry data, system operation and connection metrics, and configuration data) from a plurality of sources within the information handling system300. One source may include an integrated sensor hub396. The integrated sensor hub396may include any single source location that provides data from, for example, a temperature sensor380, a pressure sensor381, a Hall effect sensor382, a magnetic sensor383, an accelerometer384, a magnetometer385, a gyroscopic sensor386, an ultraviolet sensor387, an ambient light sensor388, and a color sensor389among other sensors. The data provided by these sensors may be classified as being included with any of the peripheral telemetry data of the wireless ecosystem persona data, the system operation and connection metrics of the link persona data, and the configuration data of the system configuration persona data. For example, the Hall effect sensor382may be placed at any location within the chassis of the information handling system300to detect the position of the individual parts of the information handling system300relative to each other. In a specific embodiment where the information handling system300is a laptop-type information handling system100, the Hall effect sensor382may be placed in one or more of a display portion or base portions of the information handling system300. In this embodiment, the Hall effect sensor382, in combination with any orientation sensor, a gyroscopic sensor386, and/or accelerometer384, may detect when the display portion is moved away from a top surface of a based portion, a relative position of the display portion to the base portion, and/or when a back side of the display portion is placed against a bottom portion of the base portion of the information handling system300. As described herein, this allows the Hall effect sensor382and other sensors to detect whether the laptop-type information handling system300is placed in an open configuration, a closed configuration, a tablet configuration, a dual tablet configuration, a laptop configuration, a tent mode configuration, a book configuration, as well as several other configurations described herein. This data may be used as part of the system configuration persona data (e.g., configuration data) and/or the link persona data (e.g., system operation and connection metrics) described herein that is later provided to the antenna controller340. The Hall effect sensor382and other sensors may be similarly used in a dual screen-type information handling system300in order to detect the relative positions of each of the screens. Again, any data obtained by the Hall effect sensor and other sensors is presented to the antenna controller340for the antenna controller340to interpret and provide that system configuration persona data as input to the antenna selection algorithm as described herein.

As part of the sensor data provided to the antenna controller340, the information handling system300may include a proximity sensor hub394that is operatively coupled to a proximity sensor344-1,344-2,344-3,344-4,344-5,344-6situated near each of the antennas348,350,352,354,356,358. In an embodiment, each proximity sensor344-1,344-2,344-3,344-4,344-5,344-6may detect the presence of a user's body part such as a hand or a lap. The detection of a user's body part may inhibit the transception of any of the antennas348,350,352,354,356,358and the antenna controller340, while executing the antenna selection algorithm, and this data may be provided as part of the input data under a category of the system operation and connection metrics. In an embodiment, the proximity sensor344-1,344-2,344-3,344-4,344-5,344-6may include a SAR detector that detects the specific absorption rate of any transmitted or received data signals. This data may also be provided to the antenna controller340for to be used as input.

The antenna controller340is also operatively coupled to the OOB Wi-Fi RF subsystem and EC330-3in order to receive system operation and connection metrics and network conditions (e.g., link delay, congestion, retries, etc.) descriptive of the available networks for the information handling system300to be coupled to, the signal QoS to any given access point or base station such as, RSSI data, BER data, SAR data, application telemetry data, among other data. This data may be obtained by the antenna controller340directing the OOB Wi-Fi RF subsystem and EC330-3to be operatively coupled to, in the embodiment shown inFIG.3, one of the second antenna350or fourth antenna354to determine what networks are available for the information handling system300to be coupled to. In order to access the second antenna350or fourth antenna354, the OOB Wi-Fi RF subsystem and EC330-3may be operatively coupled to a toggle switch368-4operated by one of the antenna controller340or the EC of the OOB Wi-Fi RF subsystem and EC330-3. In an embodiment, this scanning by the OOB Wi-Fi RF subsystem and EC330-3may be carried out continuously in order to provide the antenna controller340updated system operation and connection metrics for input into the antenna selection algorithm described herein.

During operation, the antenna controller340also receives wireless ecosystem persona data that includes peripheral device telemetry data from any peripheral device wirelessly and operatively coupled to the information handling system300or available to be wirelessly coupled to the information handling system300. This may include, for example, a wireless keyboard, a stylus, a mouse, a camera, displays, headsets, and the like. Because these peripheral devices are coupled to the information handling system300wirelessly, one of the antennas348,350,352,354,356,358may be used to communicate with these peripheral devices. The presence of these peripheral devices may indicate the information handling system300is operating under a specific persona. For example, the information handling system300may be executing an online gaming system that requires VHT for its data requirements. In this example, a mouse or VR headset is often used to allow the user to interact with the game play. As described in connection with scenario #1, this persona may prioritize for 5 GHz Wi-Fi transmissions that allows for high data through put to accommodate for the requirements of the gaming application being executed. With the data descriptive of the peripheral telemetry data, the system operation and connection metrics, and the configuration data, the antenna controller340may assign the individual antennas348,350,352,354,356,358to specific RF subsystems330-1,330-2,330-3that facilitate the best wireless connections with the access points or base stations as well as for the peripheral devices that may operate via Bluetooth, Wi-Fi, 5G, or other protocols in some embodiments. This optimizes the data transmission resources within the information handling system300based on the persona the information handling system300has detected to be operating within. By dynamically changing the assignment of the antennas348,350,352,354,356,358to the RF subsystems330-1,330-2,330-3the antenna controller340achieves this optimization on a closed loop and continual basis.

FIG.4is a block diagram illustrating two scenarios410,412under which antennas432within the information handling system400are switched among a plurality of RF subsystems according to an embodiment of the present disclosure. In this embodiment, the information handling system400may include those sensors, RF subsystems, proximity sensors, switches, and embedded controllers as those described in connection withFIG.3andFIG.1to detect one or more information handling system400personas of operation describing the information handling system wireless connectivity context for an antenna selection algorithm.

FIG.4shows that the proximity sensors receive a usage persona402that describes, at least partially, whether any number of sensors have detected the presence of a user near the information handling system (e.g., human proximity). For example, the usage persona402may include data describing the proximity of a user's body next to the information handling system400or the antennas432. This data may be RSSI data or other wireless signal quality metrics, in an embodiment. This usage data may be presented to the antenna controller of the information handling system400as described herein. In the examples described in connection withFIG.1, the usage persona402and the associated data may be used as input to the antenna selection algorithm and form part of the system and usage persona data presented as input as described in connection with Table 1.

The antenna controller of the information handling system400may also receive data that describes the wireless ecosystem persona404. This wireless ecosystem persona404may be part of the peripheral telemetry data and/or system operation and connection metrics used by the antenna controller as input to the antenna selection algorithm as described in connection withFIG.1and Table 1. In this embodiment show inFIG.4, the wireless ecosystem persona404may include data describing which of a mouse, a wireless speaker, a wireless headset, VR headset, wireless keyboard, and/or a wireless display device are wirelessly, operatively coupled to or operatively couplable to the RF subsystems such as the Wi-Fi/Bluetooth RF subsystem described herein. In an embodiment, the wireless ecosystem persona404may also include peripheral telemetry data descriptive of the connectivity requirements for the one or more peripheral devices such as which wireless communication protocol the peripheral device may communicate with the information handling system400, QoS, throughput, latency, congestion, dropped connection, among other metrics for the peripherals. In an embodiment, throughput specifications related to each of the peripheral devices may also be determined in order to determine whether a change with the combinations of peripherals operatively coupled wirelessly to the information handling system400changes the data throughput. For example, where a wireless display device and a VR headset are used as peripheral devices, the data throughput may be high thereby decreasing latency. In another embodiment where a wireless mouse and a VR headset the data throughput may be relatively low and the latency may be relatively low as well. Again, this data may be provided to the antenna controller as additional input to the antenna selection algorithm executed by the antenna controller to determine which of the antennas432should be coupled or not to specific RF subsystems. Again, in the examples described in connection withFIG.1, the wireless ecosystem persona404and the associated data may be used as input to the antenna selection algorithm and forms part of the system and usage persona data presented as input as described in connection with Table 1.

The antenna controller may also receive link persona406data describing the links available to the information handling system400for data transmissions. The link persona406may include, for example system operation and connection metrics that is received locally or also from an external information handling system management system such as Dell Optimizer® via an OOB communication to determine the available wireless networks the information handling system400may be operatively coupled to. Additional data among the link persona406may include data transception telemetry data such as latency, packet loss congestion within the network among other network telemetry data. The link persona406may also include data describing the types of data transmissions provided for audio, video, web, email, and file transferring and which priority queue these types of data are transmitted under. Additionally, the link persona406may include, for example, the type of application being executed on the information handling system400. In the examples presented herein, the amount of data transception required for a gaming or streaming application may be considered to be VHT while the data transception for an email application may be relatively lower throughput. This may include certain networking slicing data that each wireless network operates to prioritize data transception. Again, this data may be provided to the antenna controller for input into the antenna selection algorithm as described herein.

The antenna controller of the information handling system400may also receive system configuration persona data408that describes, in an example, the configuration data and/or system operation and connection metrics. In the example provided inFIG.4, the system configuration persona data408may be descriptive of the orientation and configuration of the information handling system400during use. These configurations may include one of a tablet configuration, a dual tablet configuration, a laptop configuration, a tent mode configuration, a book configuration, as well as several other configurations described herein in connection withFIG.1. Again, a variety of sensors may be used to determine the configuration and/or orientation of the information handling system400that includes, for example, a Hall effect sensor, a magnetometer, a proximity sensor, a hinge sensor, a light sensor, and a camera, among other sensors. The antenna controller of the information handling system400may also receive this additional system configuration persona data408as input to the antenna selection algorithm. As described in connection withFIG.1and Table 1, this system configuration persona data408may form part of the system and usage persona data used as input to the antenna selection algorithm in order to receive output in the form of a selection of which antennas are assigned to one of a plurality of RF radio subsystems.

With the usage persona402, the wireless ecosystem persona404and any peripheral telemetry data, link persona406system operation and connection metrics, the system configuration persona408, and usage persona402, the antenna controller may input this data into an antenna selection algorithm to receive as output a determination as to how the antenna controller to switch between operating transceiving antennas by accessing one or more RF switches to dynamically change the assignment of the plurality of antennas432to the or more peripheral devices and plurality of operating wireless links. In an embodiment, the antenna selection algorithm may access a table such as Table 1, or be fed as inputs to a machine learning classifier to determine correlations to wireless contexts or to antenna assignments.

In one example embodiment, the embedded controller or processor executing code instructions of an antenna selection algorithm may access a Table and associated detected data from the personas402,404,406, and408and other data inputs with a wireless context of scenario #1 of Table 1. Scenario #1410shows a graphical depiction of scenario #1 in Table 1 described herein. In scenario #1 (as described in the third row, Table 1 and inFIG.1), system and usage persona data includes a first column that describes system configuration persona data descriptive of, at least, the configuration of the information handling system as described herein. In scenario #1, this system configuration persona includes an indication that the lid of the information handling system400is open. Scenario #1 also indicates that the usage context of the information handling system400. This usage persona may include data related to system operation and connection metrics and specifically whether, in this example, human presence is detected near the information handling system400. Again, this data may be obtained from a number of sensors. Scenario #1 also describes the wireless ecosystem persona that includes, among other potential data, peripheral device connection status (e.g., connected, not connected, sleep state, available, etc.) and the peripheral telemetry data. Peripheral devices are used by a user to interact with the information handling system400and to provide output to the user or that the user implements to provide input to the information handling system400. These peripheral devices may include the wireless I/O devices described herein that includes a mouse and a headset. In the first scenario, an audio headset operating under a Wi-Fi wireless protocol and a mouse operating under a Bluetooth® (“BT”) wireless protocol are indicated as being present within the persona context. Because a user may interact with, for example, an online gaming application being executed on the information handling system400, the headset may be used by the user to interact verbally with other online users and hear gameplay sounds. The mouse may also be used by a user during the execution of a gaming application to make selections during gameplay. The information handling system400may have one or more antennas432to operatively couple these peripheral devices to the information handling system400.

Scenario #1 also indicates that the link persona under which the RF subsystems are currently operating under indicates that the host Wi-Fi or the Wi-Fi RF is operating under very high data throughput (VHT) and a concurrent dual-band (CDB) mode. The VHT mode may also be a result of the type of application being executed on the information handling system400from usage persona data such as the audio-visual streaming application or online gaming application described herein both of which have a relatively higher transception of data across a network than, for example, an email application.

As such, in scenario #1, with the inputs into the antenna selection algorithm such as the usage persona402, the wireless ecosystem persona404, link persona406, and system configuration persona data408as provided as the peripheral telemetry data, the system operation and connection metrics, and the configuration data (e.g., examples shown in columns 2-5 of Table 1), the antennas432may be assigned to specific RF subsystem accordingly.

Continuing with scenario #1 in Table 1 with reference toFIG.4, a WWAN radio (e.g., second RF subsystem130-2with its second RF front end125-2,FIG.1) may have four antennas, a first antenna, a second antenna, a third antenna, and fourth antenna, to transceive data using a specific wireless protocol. Although these four antennas may be operatively coupled to a WWAN radio such as a cellular RF subsystem, one of these antennas (e.g., a second antenna) may be switched from being operatively coupled to the cellular RF subsystem to an out-of-band (OOB) Wi-Fi RF subsystem (e.g., the third RF subsystem130-3with its third RF front end125-3,FIG.1) controlled by an embedded controller (EC). Moreover, one or more antennas may be designated for concurrent Bluetooth operation depending on the detected wireless connectivity context of the plural personas for the information handling system400. This may be done according to the output presented to the antenna controller after executing the antenna selection algorithm. According to this output, the first antenna may be operatively coupled to the second RF subsystem via the second RF front end to scan for cellular network connectivity. The second antenna (as indicated in the 7thcolumn, Scenario #1, Table 1) may not be connected to the second RF subsystem and, instead operatively coupled to the third RF subsystem to scan for the OOB provisioning and receiving of the system operation and connection metrics as described herein. The third antenna may be operatively coupled to the first RF subsystem via the first RF front end to operate under a 5 GHz frequency. The fourth antenna is also operatively coupled to the first RF subsystem via the first RF front end and used to operate under a 5 GHz frequency. This is done in order to optimize the Wi-Fi connectivity per the radio context presented in this scenario (column 5, scenario #1, Table 1) that indicates that a very high throughput (VHT) is necessary to transceive the data to and from the information handling system400. The antenna controller may assign these antennas to these RF subsystems via use of one or more switches (e.g.,168-1,168-2, and168-3,FIG.1) as described in more detail in connection withFIG.3herein.

Table 1 also shows two antennas (e.g., a fifth antenna156and a sixth antenna158,FIG.1) may be associated with a host (e.g., information handling system400) Wi-Fi Radio such as a Wi-F-RF subsystem (e.g., first RF subsystem130-1with its first RF front end125-1,FIG.1). In scenario #1, the fifth antenna is switched from the first RF subsystem to be used by the second RF subsystem via a first switch. This allows the second RF subsystem to operate under a concurrent dual band (e.g., column 5, scenario #1, Table 1) at, for example, 5 GHz and 2.4 GHz. This allows the fifth antenna to be concurrently, operatively coupled to a Wi-Fi protocol network as well as, in this example scenario #1, a peripheral device such as a mouse (column 12, scenario #1, Table 1) under Bluetooth. In an embodiment, the sixth antenna may be operatively coupled, at 2.4 GHz, to another peripheral device such as a headset via Bluetooth communication.

The arrangement of the antennas432to be operatively coupled to a specific RF subsystem via manipulation of one or more switches allows for the antenna controller to prioritize for specific wireless protocols (in scenario #1 a Wi-Fi wireless protocol) based on the received peripheral telemetry data, system operation and connection metrics, and configuration data and the persona data described herein. By using this data to assign the antennas432in this manner the information handling system400may intelligently manage resources, in a closed loop fashion, to distribute wireless resources based on the persona in which the information handling system400is currently working under. This allows for the selection of the best antennas432to use for connection to a network and any peripheral device at any given time. In this manner the information handling system400can dynamically distribute and optimize these wireless resources by defining a usage persona402, wireless ecosystem persona404, link persona406, and system configuration persona data408and, through continual closed loop feedback, optimize those wireless resources accordingly. Scenario #2 (e.g., also described in Table 1 as scenario #2) also shows a second scenario where the switches may be accessed by the antenna controller to optimize the use of those wireless resources based on the input (e.g., columns 2-5, scenario #2, Table 1) according to a new persona the information handling system400has detected to be within. Like the first scenario, scenario #2 includes system configuration persona408data indicating that the information handling system400is currently in a tablet configuration. The usage persona data indicates that there is human proximity next to at least one antenna432. The wireless ecosystem persona data indicates that no peripheral device is currently couplable to the information handling system400as indicated in Table 1. Additionally, the link persona data indicates that the host Wi-Fi or the Wi-Fi RF subsystem is operating under very high data throughput (VHT) and a concurrent dual-band (CDB) mode with some of the antennas operating under a 4×4 MIMO LTE protocol. Again, as output, a first antenna is connected to the second RF subsystem. A second antenna is also operatively coupled to the second RF subsystem under a MIMO configuration. A third antenna is indicated as not being connected but instead is used by the third RF subsystem to scan for a wireless connection. A fourth antenna is connected to a Wi-Fi network using a 5 GHz frequency. A fifth antenna and sixth antenna are also connected to a Wi-Fi network at using a 5 GHz frequency.

Although, Table 1 shows two scenarios, it is appreciated that more than two scenarios may be presented or maintained on such a look-up table. As such, it is appreciated that more rows may be added to Table 1 as additional and different inputs (e.g., usage persona, system persona, wireless ecosystem persona, the link persona, and other aspects of the information handling system400wireless connectivity context for antenna control) are presented to the antenna selection algorithm and used to determine how to assign the antennas to the RF subsystems.

FIG.5is a flow diagram illustrating a method500of executing an antenna selection algorithm executed by an information handling system according to an embodiment of the present disclosure. The method500may include, at block502, initiating, via a wireless interface adapter of the information handling system, a sideband communication via a wireless link such as Wi-Fi to obtain data about a plurality of operating wireless links for a plurality of transceiving antennas on the information handling system from a remote information handling system management system such as Dell Optimizer®. As described herein, this sideband communication, when executed by an antenna controller and embedded controller, for example, initiates a sideband communication with at least one of the plurality of radios described herein and may establish a wireless connection via a OOB Wi-Fi RF subsystem to one or more networks. In an embodiment, the sideband communication may provide any wireless communication link with any wireless network. In an embodiment, a sideband communication link achieved via execution of the sideband serial messaging protocol may also allow the antenna controller to determine locally from RF subsystems which wireless networks and protocols are available to operatively couple the information handling system to a wireless network as well as any system operation and connection metrics associated with those wireless networks. Again, because the system operation and connection metrics include data descriptive of measured RSSI values and other metrics relating to signal quality and strength of any of each of a plurality of communication networks, the data obtained by the antenna controller may be used during execution of the antenna selection algorithm by an antenna selection controller or processor to determine which wireless network to operatively couple the information handling system to for various applications executing depending on the wireless connectivity context of the information handling system. In an embodiment, the antenna selection algorithm may include computer executable program code that, when executed by the antenna controller, receives these inputs and provides output describing which antennas to use to operatively couple an RF subsystem to one or more wireless networks and for wireless peripheral device operations.

The method500further includes receiving, at the antenna controller, a system configuration persona describing system operation and connection metrics at block504. In an embodiment, the system configuration persona may describe whether human presence is detected near the information handling system. This data associated with the system configuration persona may be obtained from a number of sensors including a proximity sensor and/or a SAR detector. The system configuration persona may also include other system operation and connection metrics that include application telemetry data descriptive of an application being executed on the information handling system. The configuration of the information handling system may be determined by the antenna controller using a number of additional types of sensors. In the context of the information handling system being a 360-degree-type laptop, these sensors may be used to determine if the orientation the information handling system is placed in is one of a tablet configuration, a dual tablet configuration, a laptop configuration, a tent mode configuration, a book configuration, as well as several other configurations described herein. These variety of sensors may include, for example, a Hall effect sensor, a magnetometer, a proximity sensor, a hinge sensor, a light sensor, and a camera, among other sensors. Referring toFIG.1, the antenna controller140may receive data from an integrated sensor hub data relating to orientation of the information handling system as described herein.

In an example embodiment, the Hall effect sensor, orientation sensors, or other sensors may be placed at any location within the chassis of the information handling system to detect the position of the individual parts of the information handling system relative to each other. In a specific embodiment where the information handling system is a laptop-type information handling system, the Hall effect sensor, orientation sensors, or other sensors may be placed in one or more of a display portion or base portions of the information handling system. In this embodiment, these sensors may detect when the display portion is moved away from a top surface of a based portion, a relative position of the display portion to the base portion, and/or when a back side of the display portion is placed against a bottom portion of the base portion of the information handling system. As described herein, this allows the sensor hub to detect whether the laptop-type information handling system is placed in a tablet configuration, a dual tablet configuration, a laptop configuration, a tent mode configuration, a book configuration, as well as several other configurations described herein. The sensor hub may be similarly used in a dual screen-type information handling system in order to detect the relative positions of each of the screens. Again, any data obtained by the sensor hub is presented to the antenna controller for the antenna controller to interpret and provide that orientation data as input to the antenna selection algorithm as described herein.

In an example embodiment, a magnetometer may be used to measure the earth's magnetic field at any location in order to detect an orientation of the information handling system relative to that magnetic field. In a specific embodiment, the magnetometer may be a three-axis magnetometer that eliminates the sensitivity to the way in which the information handling system is held or positioned. Again, any data obtained by the magnetometer, such as via a sensor hub, is presented to the antenna controller for the antenna controller to interpret and provide as input to the antenna selection algorithm as described herein.

As this configuration data is provided to the antenna controller at block508, the antenna controller may determine, for example, whether the lid (e.g., display chassis) is closed or not. Again, because higher frequencies transmit and receive data at a relatively higher throughput, these higher frequencies may be more susceptible to physical barriers blocking the signal and metallic objects interfering with the signals. Because the lid of the information handling system may be made of metal and because it is placed at a relatively closer distance to the antennas when it is closed, this may affect the transmission capabilities of the antennas especially as the transmission and reception frequencies are higher.

The method500may further include receiving, at an antenna controller, a wireless ecosystem persona from a RF subsystem operatively coupling one or more peripheral devices to the information handling system, the wireless ecosystem persona data being descriptive of the connectivity requirements for the one or more peripheral devices at block506. In an embodiment such as that described in connection withFIG.3, the information handling system may include four WLAN antennas and two WWAN antennas. The locations of these antennas within the information handling system (e.g., along a right side of the base chassis, left side of the base chassis, in a hinge of the information handling system, etc.) and their positions relative to a peripheral device may influence their transception capabilities relative to a peripheral device. Additionally, the type of peripheral device and the frequency at which they communicate with the information handling system may be provided as part of this peripheral telemetry data. The method500may continue at block508with receiving, at the antenna controller, a usage persona descriptive of system operation and connection metrics from one or more wireless networks via the sideband serial messaging protocol and out-of-band (OOB) communications related to the plurality of operating wireless links. In an embodiment, this data may be obtained from a number of sensors including a proximity sensor and/or SAR detectors. In this embodiment, the power levels provided to the antennas of the information handling system may be compared to the data received by the proximity sensors to determine, for example, these SAR safety limitations as well as determine whether, for example, a user's body part or a peripheral device such as a stylus is absorbing this RF electromagnetic radiation. In an embodiment, this proximity data (e.g., SAR data) may be received via operation of a number of proximity sensors located at or near each of the antennas of the antenna systems described herein. Because the presence of a user's body part (e.g., a user's hand) may interfere with the transmission and reception of data, the antenna controller may use this data to determine which of the plurality of antennas should be operatively coupled to a RF subsystem operating under a prioritized wireless protocol. In reference toFIG.3, for example, the antenna controller340may receive data from the proximity sensor hub394relating to the proximity of a user to antennas at relative locations on the information handling system.

The method500also includes, at block510, receiving, at the antenna controller, a link persona from one or more wireless networks via the sideband serial messaging protocol and out-of-band (OOB) communications to the plurality of operating wireless links. The link persona indicates that the host Wi-Fi or the Wi-Fi RF subsystem is operating under very high data throughput (VHT) and a concurrent dual-band (CDB) mode. The VHT mode may be a result of the type of application being executed on the information handling system such as the audio-visual streaming application or online gaming application described herein both of which have a relatively higher transception of data across a network than, for example, an email application. The CDB (aka: simultaneous dual band), in relation to the operation of any antenna, may be the operation of those antennas at two separate networks or devices simultaneously using both 2.4- and 5-GHz frequency bands, for example. This, along with potentially doubling the available bandwidth, allows for more reliable network connections to be established. In an example embodiment, the link persona may include data describing that an audio/video streaming application is being executed that indicates that a relatively higher data transmission bandwidth low latency (avoid stalls) is necessary to properly execute that application in comparison to, for example, the execution of an email application. Similarly, an online gaming application may also be an example application that indicates that data transmissions may be high during execution and the system operation and connection metrics presented in the third column describing this usage context. Still further, in an embodiment, the link persona data may also include data describing latency, packet loss, network congestion, and prediction error either detectable at the radios of the information handling system or via the sideband communications establishing the OOB communication with an information handling system management system such as Dell Optimizer®. Still further, the link persona may also include data describing total available bandwidth on any given network. Again, this data may be provided via the sideband communications establishing the OOB communication with an information handling system management system and may describe what network slices are provided for the various data transmission (e.g., audio data, video data, web traffic, email data, and file transfer data).

The method also includes, at block512, executing, with a processor, an antenna selection algorithm to use, as input, the peripheral telemetry data, the system operation and connection metrics, and the configuration data to output a connectivity resource mapping (e.g., Table 1) used to assign the plurality of antennas to be communicatively coupled to the one or more peripheral devices and plurality of operating wireless links. In one embodiment, the antenna selection algorithm may input detected link persona, wireless ecosystem persona, system configuration persona, and usage persona and other data into an artificial neural network, Bayesian network, decision trees, regression analysis, or other machine learning service algorithms that may be used to model the output within which the information handling system operates via classifiers to correlate antenna assignments (or setup) as an output and provide a closed loop system that can dynamically distribute and optimize resources (e.g., RF subsystems130-1,130-2,130-3and antennas148,150,152,154,156,158,FIG.1) by providing feedback or output to optimize the connectivity of the information handling system and its plural antennas and RF subsystems to the various wireless networks. In an embodiment, the antenna selection algorithm applies a machine learning methodology to determine correlations of the influencing factors including the link persona, the wireless ecosystem persona, the system configuration persona, usage persona, and other persona metrics in embodiments described herein and detect changes to any of these influencing factors to suggest or automatically apply changes to a mapping and the assignment of any of the antennas to any of the RF subsystems. In some aspects, suggested predictive adjustments or notice of automatic predictive adjustments may be confirmed or declined by the user. In an embodiment, the suggested adjustments may be provided to the antenna controller. Based on these selected adjustments, the antenna controller may send signals to the RF to cause the suggested assignments of the antennas to the suggested RF subsystems in order to increase the optimized use of the transceiving antennas while the information handling system operates within the detected persona.

In some embodiments, the antenna selection algorithm may include or use, in whole or in part, a look-up table. This look-up table may include a number of triggers that may be used to define the peripheral telemetry data, the system operation and connection metrics, and configuration data. The look-up table may also include an antenna assignment as output based on the peripheral telemetry data, the system operation and connection metrics, and configuration data as described. In an embodiment, where the information handling includes six antennas, such a look-up table may look like Table 1 as described in connection withFIG.1. The embedded controller or microcontroller unit (e.g., antenna controller) executing the antenna selection algorithm may correlate detected data of link persona, the wireless ecosystem persona, the system configuration persona, usage persona with a scenario from the table (e.g., Table 1) to determine antenna assignments. In some embodiments, the antenna selection algorithm may use a machine learning classifier to assist with correlation to table entries for scenario identification.

Based on the outputs due to the execution of the antenna selection algorithm by the antenna controller, the antenna controller may, at block514, switch between operating transceiving antennas by accessing one or more RF switches to dynamically change the assignment of the plurality of antennas to the or more peripheral devices and plurality of operating wireless links. The operations of this switching, in some examples, is depicted in Table 1. For table 1, the antenna controller may select among four WLAN antennas and two WWAN antennas in order to dynamically change the assignment of the plurality of antennas to the or more peripheral devices and plurality of operating wireless links.

The method500may continue at block516with determining whether the link persona, the wireless ecosystem persona, the system configuration persona, usage persona have changed. Because this data is provided to the antenna controller in a closed-loop fashion, the antenna controller may periodically poll this data. Changes to this data may be detected when the antenna controller detects a change in any of the usage persona data, the wireless ecosystem persona data, the link persona data, or system configuration persona data described inFIG.4. This may cause the antenna controller to again pull the link persona, the wireless ecosystem persona, the system configuration persona, usage persona at blocks504through510, executing the antenna selection algorithm at block510, and, when necessary, changing the assignment of the plurality of antennas to the or more peripheral devices and plurality of operating wireless links. Where this data is stable at block516and where it is determined at block518that either wireless functions or the information handling system is turned off, the method500may end. Otherwise, the information handling system may continue to monitor for selection among switched antennas depending on changes in the link persona, the wireless ecosystem persona, the system configuration persona, usage persona, or other factors as discussed in some embodiments.
