Further, various technical terms are used throughout this description. An illustrative resource that fleshes out various aspects of these terms can be found in Newton's Telecom Dictionary, 31st Edition (2018).
Embodiments of the technology described herein may be embodied as, among other things, a method, system, or computer-program product. Accordingly, the embodiments may take the form of a hardware embodiment, or an embodiment combining software and hardware. An embodiment takes the form of a computer-program product that includes computer-useable instructions embodied on one or more computer-readable media.
Computer-readable media include both volatile and nonvolatile media, removable and nonremovable media, and contemplate media readable by a database, a switch, and various other network devices. Network switches, routers, and related components are conventional in nature, as are means of communicating with the same. By way of example, and not limitation, computer-readable media comprise computer-storage media and communications media.
Computer-storage media, or machine-readable media, include media implemented in any method or technology for storing information. Examples of stored information include computer-useable instructions, data structures, program modules, and other data representations. Computer-storage media include, but are not limited to RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile discs (DVD), holographic media or other optical disc storage, magnetic cassettes, magnetic tape, magnetic disk storage, and other magnetic storage devices. These memory components can store data momentarily, temporarily, or permanently.
Communications media typically store computer-useable instructions—including data structures and program modules—in a modulated data signal. The term “modulated data signal” refers to a propagated signal that has one or more of its characteristics set or changed to encode information in the signal. Communications media include any information-delivery media. By way of example but not limitation, communications media include wired media, such as a wired network or direct-wired connection, and wireless media such as acoustic, infrared, radio, microwave, spread-spectrum, optical, and other wireless media technologies. Combinations of the above are included within the scope of computer-readable media.
By way of background, certain conventional wireless communications systems rely on radio frequency (RF) communications to send and receive data to one or more devices. However, certain current conventional implementations of RF communications systems may not propagate through certain materials, e.g., certain building materials, such as low emissivity glass, leading to reduced quality user experience. Certain conventional implementations of RF communications systems, in various scenarios, also may not have the capacity to handle all data needs of devices connected to the cell site. Thus, there is a need for alternative systems and methods for providing wireless communications to a device.
The systems and methods disclosed herein can alleviate one or more of the aforementioned problems. For example, in aspects, the systems disclosed herein can utilize both optical and RF communications. In such aspects, the systems and methods disclosed herein can leverage the use of both optical and RF transmission to provide increased bandwidth and reliability of communications or data to a device. In certain aspects, the systems and methods disclosed herein may utilize optical transmission for non-critical communications, e.g., video downloads, web browsing, etc., which may reduce capacity on a cell site's RF resources, freeing up RF resources for critical communications, such as voice calls, live video streaming, or text messaging. Further, in certain aspects, the systems and methods described herein can use optical and RF transmission to complement one another e.g., utilize optical transmission when there is reduced RF signal strength, and/or utilize RF transmission when optical transmission is not available. In such aspects, as discussed below, this complementary use of RF and optical transmission can provide enhanced coverage in certain areas that may pose a challenge using current conventional RF systems.
Accordingly, in one aspect, a system for providing wireless communications for a device is provided. The system includes at least one antenna array comprising a plurality of antenna elements; at least one optical array comprising a plurality of optical transmitters; and a processor. The processor is configured to execute operations that can include receiving a first indication, at a first time, that a device is capable of receiving data via optical transmission. The operations can further include utilizing an optical transmitter of the plurality of optical transmitters to transmit one or more first packets of data to the device via optical transmission; and utilizing an antenna element of the plurality of antenna elements to transmit one or more second packets of data to the device via radio frequency (RF) transmission.
In another aspect, a method for providing wireless communications for a device is provided. The method can include receiving a first indication, at a first time, that a device is capable of receiving data via optical transmission.

In the same or alternative aspects, the information from the database 210 may include any information associated with prior optical transmissions to a specific location where the user device is, e.g., GPS coordinates, optical beam direction, and/or orientation.
In aspects, the determiner 218 can determine whether or not the cell site 214 will send data via optical transmission to the user device. In such aspects, the determiner 218 can determine that the user device is capable of receiving data via optical transmission, e.g., based on the receipt via the first receiver 216 of an indication to that effect from the user device. In the same or alternative aspects, the determiner 218 can determine that the cell site 214 is capable of sending data via optical transmission to the user device. In such aspects, the determiner 218 can determine that one or more optical transmitters are capable of transmitting data to the user device, e.g., that such transmitters are functioning and available, and are capable of orienting to the user device.
In various aspects, the determiner 218 can determine if all or a portion of the requested data should be transmitted to the user device via optical transmission, RF transmission, or both. For example, the determiner 218 can determine whether or not the requested data is associated with non-critical communications. In aspects, non-critical communications can include data associated with video downloads, picture downloads, audio downloads, website browsing, or a combination thereof. In aspects, when the data requested by the user device is associated with non-critical communications, the determiner 218 can determine that such data will be communicated to the user device via optical transmission. In the same or alternative aspects, the determiner 218 can determine whether or not the requested data is associated with critical communications. In aspects, critical communications can include data associated with a voice call, text messaging, live video download and/or streaming, or a combination thereof. In aspects, when the data requested by the user device is associated with critical communications, the determiner 218 can determine that such information is to be communicated to the user device via RF transmission.
In aspects, the assigner 220 can assign a specified mode of data transmission for all or a portion of the data requested by the device. In aspects, the assigner 220 can assign a mode of data transmission, e.g., optical transmission or RF transmission, that was determined by the determiner 218 for all or a portion of the data requested by the device. For instance, when the determiner 218 determines that requested data to be sent to the device will be communicated via optical transmission, the assigner 220 can assign the mode of optical transmission for communicating that requested data to the device. In the same or alternative aspects, when the determiner 218 determines that requested data to be sent to the device will be communicated via RF transmission, the assigner 220 will assign the mode of RF transmission for communicating that requested data to the device. In aspects, the assigner 220 may also cause the transmission of the requested data using the assigned mode of transmission.
In various aspects, the second receiver 222 can receive information from a device in communication or initiation of communication with the cell site 214. In aspects, the second receiver 222 can receive data uploads from the device, e.g., to the network 208. In certain aspects, the second receiver 223 can receive data from the device via optical transmission from the device. In various aspects, a user device may utilize optical transmission to upload video, images, music, or the like, to the network 208.

In certain aspects, the user device 400 can optionally include an optical transmitter, e.g., for uploading data to the cell site and/or network. As can be seen in the aspect depicted in FIGS. 4A and 4B, the user device 400 is depicted as having an optional optical transmitter 402 positioned on a side 407 of the user device 400. In aspects, the optical transmitter 402 can be any convenient type of optical transmitter, and can include an infrared transmitter, visible light transmitter, or UV transmitter, including but not limited to a laser and/or an LED.
FIG. 5 schematically depicts one example method 500 for providing wireless communications for a device. The method starts at the step 502, where a user device attempts to communicate with a network, e.g., the network 208 depicted in FIG. 2. At the step 504, it is determined if the device can receive data via optical transmission. In aspects, the step 504 can be performed by the communicator 212 and/or the determiner 218 of the network environment 200 depicted in FIG. 2. In one aspect, the step 504 can include confirming that the device has communicated to the network and/or to the cell site that the device is capable of receiving data via optical transmission. In aspects, such a confirmation can include the first receiver 216 of the communicator 212 of the network environment 200 depicted in FIG. 2 receiving an indication or communication from the device regarding the ability of the device to receive data via optical transmission. In the same or alternative aspects, the step 504 can include receiving the desired wavelength and other information for successfully communicating data via optical transmission to the device. When it is determined that the device cannot receive data via optical transmission and/or it is determined that the cell site does not have the current available resources to provide data via optical transmission to the device, the requested data is transmitted to the device via RF transmission at the step 506. In aspects, once the device receives the requested data in the step 506, the device may return to the step 502 to request further data and/or to transmit data to the network.
If it is determined at the step 504 that the device is capable of receiving data via optical transmission, and/or that the cell site has the current available resources to provide data via optical transmission, the method 500 proceeds to the step 508. In the step 508, it is determined if the data to be transmitted to the device is associated with critical communications. For instance, as discussed above, in aspects, the cell site and/or network may prioritize sending critical communications to devices via RF transmission. In aspects, as discussed above, certain example critical communications include voice calls, text messages, live video, or a combination thereof. In the method 500 depicted in FIG. 5, when the requested data is considered to be critical communications, the method proceeds to the step 506, where such data is transmitted to the device via RF transmission. When the requested data is non-critical communications, e.g., data associated with a video download, picture download, audio download, website browsing, or a combination thereof, the method 500 proceeds to the step 510. In aspects, the determiner 218 of the communicator 212 of the network environment 200 depicted in FIG. 2 can be utilized to perform at least a portion of the determinations made in the step 508. In aspects, once it is determined what transmission mode is to be utilized, the requested data can be assigned such a transmission mode by the assigner 220 of the communicator 212 of the network environment 200 depicted in FIG. 2.
In the step 510, the requested data is transmitted via optical transmission. In aspects, the optical array 306 of the base station 300 depicted in FIG. 3 can be utilized to provide data to the device via optical transmission. In aspects, once the device receives the requested data in the step 508, the device may return to the start 502 to request further data and/or to transmit data to the network.
In aspects, by transmitting non-critical data or any data via optical transmission, there is enhanced user experience, as optical transmission has increased bandwidth and download speeds compared to current RF technologies, e.g., 5G. Further, in aspects, utilizing optical transmission for non-critical data transmission frees up bandwidth and/or capacity on the RF side of the network and/or cell site.
It should be understood that the method 500 depicted in FIG. 5 is just one example method and that variations on this method are also contemplated by the disclosure herein. For instance, in one variation of an example method, the step 508 is not included, in certain aspects. In such a variation on an example method, any requested data, both critical and non-critical communications, can be provided to the device via optical transmission.
FIG. 6 depicts an example network environment 600, where various non-limiting example scenarios are depicted, for the use of the systems and methods for providing wireless communications for a device disclosed herein. In the aspect depicted in FIG. 6, a network environment 600, a base station 610, a building 612, and user devices 614 and 616 are depicted. In one aspect, the base station 610 can include any or all of the properties of the base station 300 discussed above with reference to FIG. 3. Further, the network environment 600 can include any or all of the properties of the network environment 200 discussed above with reference to FIG. 2.
In the aspect depicted in FIG. 6, the user device 614 is positioned within a line of sight of the base station 610. In such aspects, when a user device is positioned within a line of sight of the base station 610, the user device 614 is positioned within a line of sight of one or more antenna arrays 611 and/or one or more optical arrays 613 of the base station 610. In aspects, a user device can be considered positioned within a line a line of sight of a base station when there is no physical objects in-between the user device and the base station that may disrupt the optical transmission of data between the user device and the base station, e.g., no trees, no buildings, and/or no or other structures. In the aspect depicted in FIG. 6, since the user device 614 is positioned within a line of sight of the base station 610, the user device can receive data via optical transmission from the base station 610, and/or transmit via optical transmission data from the user device 614 to the base station 610.
In the aspect depicted in FIG. 6, the user device 616 is depicted as not being in line of sight with the base station 610. In this aspect, a building 612 is depicted as blocking or disrupting the line of sight between the user device 616 and the base station 610. In aspects, since the user device 616 is not in line of sight with the base station 610, the user device 616 can communicate with the base station 610 via RF communication. In the same or alternative aspects, the user device may move from behind the building 612 and then be in line of sight with the base station 610 where the user device 616 may then receive and/or transmit data via optical transmission with the base station 610.
In certain aspects, a user device may be able to receive data via optical transmission while in a structure, such as a building. For instance, in certain aspects, when a user device is positioned at or near a window, e.g., at the position identified by the arrow 618, when inside the building 612, such a user device may have a line of sight to the base station 610 and can be capable of receiving and/or sending data via optical transmission. In such aspects, the methods and systems disclosed herein can provide increased connectivity to users in various circumstances. For example, in various aspects, certain RF wireless communication protocols, e.g., 5G, may have reduced signal strength when a low emissivity (Low-E) window is in between a user device and a base station. In the scenario where the window by the position identified by the arrow 618 in the building 612 is a Low-E window, a user may have reduced RF communication capabilities, yet the user's device may be able to utilize optical transmission to receive and/or send data. In such an aspect, the network environment 600 is capable of utilizing optical transmission to reduce a potential deficiency in the RF transmission capabilities.
In one or more aspects, a user device positioned inside the building 612 but away from a window, e.g., at the position identified by the arrow 620, may not have line of sight to the base station 610. In such an aspect, the user device may transmit and/or receive data from the base station 610 via RF transmission, which is capable of effective communication even in the absence of line of sight between the base station 610 and a user device. In one scenario, a user device may move around within the building 612, e.g., between the positions represented by the arrows 618 and 620, and may rely on optical transmission, e.g., when at the position represented by the arrow 618, and may rely on RF transmission, e.g., when at the position represented by the arrow 620, for communication with the base station 610.
FIG. 7 is a flow chart of a method 700 for providing wireless communications for a device. In the step 710 of the method 700, a first indication is received, at a first time, that a device is capable of receiving data via optical transmission. In various aspects, at the first time, the device can have a direct line of sight to an optical array and/or to a base station. In aspects, the first indication can be received by the first receiver 216 of the communicator 212 of the network environment 200 discussed above with reference to FIG. 2. In aspects, the first indication can be communicated from the device using RF transmission. In one or more aspects, the first indication can include a specified wavelength for optical transmission.
In the step 720 of the method 700, an optical transmitter is utilized to transmit one or more first packets of data to the device. In aspects, the optical transmitter can include a laser, LED, or a combination thereof. In various aspects, the one or more first packets of data can be associated with non-critical communications. In aspects, the non-critical communications can include data associated with a video download, picture download, audio download, website browsing, or a combination thereof. In aspects, the assigner 220 of the network environment 200 discussed above with reference to FIG. 2 may assign the one or more first packets of data to be transmitted by optical transmission and/or may cause the optical transmission of the one or more first packets of data.
In various aspects, prior to the step 720, the method 700 can include a step of determining whether or not the cell site will send data via optical transmission to the user device and/or determining if all or a portion of the requested data should be transmitted to the device via optical transmission. In such aspects, such an additional step may be performed by the determiner 218 of the communicator 212 of the network environment 200 discussed above with reference to FIG. 2. For example in certain aspects, such an additional step can include determining if the requested data is associated with non-critical communications and that such data should be provided via optical transmission.
In the step 730 of the method 700, an antenna element is utilized to transmit one or more second packets of data to the device via RF transmission. In one aspect, the RF transmission can include one or more RF wireless communication protocols, such as a 3G, 4G, 5G, LTE, CDMA, 6G, or a combination thereof. In aspects, the one or more second packets of data can be associated with critical communications, including but not limited to a voice call, text messaging, live video, or a combination thereof. In certain aspects, the step 730 and the step 720 can occur at the same time or the step 730 can occur before the step 720 (or even before the step 710), or at substantially the same time, or within 10 seconds, or 5 seconds, or 1 second of one another. In the same or alternative aspects, the step 720 and the step 730 can occur while the user device is in substantially the same location, e.g., within a 3 or 5 meter radius. It should be understood that the terms first packets of data and second packets of data do not imply an order to which such packets of data are transmitted. For instance, as discussed above, in certain aspects, the step 730 where an antenna element may be utilized to transmit one or more second packets of data via RF transmission, may occur prior to (or at the same time as) the step 720, where an optical array is utilized to transmit one or more first packets of data.
In aspects, prior to the step 730 of the method 700, a second indication can be received, at a second time, that the device is not capable of receiving data via optical transmission. In such aspects, the second indication can be received by the first receiver 216 of the communicator 212 of the network environment 200 discussed above with reference to FIG. 2. In various aspects, at the second time, the device may not have a direct line of sight to an optical array and/or to a base station. In certain aspects, at the second time, the device may be at a location that is different from the location the device is at, at the first time. In one or more aspects, the second indication can be communicated from the device using RF transmission. In aspects, the step 730 can be performed in response to receiving such a second indication that the device is not capable of receiving data via optical transmission.
