## Background
PRIORITY APPLICATION
This application is a U.S. National Stage Application under 35 U.S.C. 371 from International Application No. PCT/US2011/067913, filed Dec. 29, 2011, which is hereby incorporated by reference in its entirety.
TECHNICAL FIELD
The present technology relates generally to the field of wireless communications, and more particularly to antennas used in wireless communications.
BACKGROUND
Regulatory compliance for a wireless device is procured with a certain antenna paired to the device. In theory, it is difficult for a user to replace the original antenna with an aftermarket antenna which offers increased performance. However, it is increasingly easy to find aftermarket antennas for both desktop PCs and notebooks PCs with (SubMiniature version A) SMA, Reverse SMA or Micro-coax connectors. Care must be taken when matching antennas with certain devices as the devices may not meet regulatory standards when paired with certain antennas. Also, antenna tuners and matching networks are being integrated into wireless modules (or antennas) to enable ‘per device’ optimization (e.g., optimizing wireless transmission characteristics per specific device) and ‘in use’ optimization (e.g., optimizing wireless transmission characteristics based upon sensed usages that would result in VSWR (voltage standing wave ratio) changes) of VSWR and efficiency for notebooks, tablets and phones. Typically a single radio module may be integrated with several different antennas based on the device form factor.

DESCRIPTION
The following description and the drawings sufficiently illustrate specific embodiments to enable those skilled in the art to practice them. Other embodiments may incorporate structural, logical, electrical, process, and other changes. Portions and features of some embodiments may be included in, or substituted for, those of other embodiments.
Disclosed in some examples are methods, devices, and machine-readable media which allow a wireless module to identify the antenna to which it is connected. Based on the connected antenna the wireless module may modify one or more parameters.
According to one embodiment, illustrated in FIGS. 1A and 1B, there is provided an antenna module 100 and a wireless module 110, wherein the antenna module 100 includes a built-in self-identification device, such as an integrated circuit (IC) device or chip 105 that stores a unique identifier 107, for example a 64-bit serial number for an antenna on which it is attached, mounted, fastened together, glued together, contained together, or otherwise physically paired, for example in a plastic module. More generally, the unique identifier 107 is alternatively referred to herein as machine-readable identification data. The wireless module 110 may contain radio frequency (RF) processing circuits or components, such as an RF chip 115 and a baseband chip 120. The wireless module 110 may query the device 105 and acquire the unique identifier 107, for example the serial number, for the antenna. This query may be done one-time at initialization of the wireless module 110, periodically upon detection of a change in the antenna or antenna module, or at other times.
FIG. 2 illustrates one example method 200 of verifying antenna compliance. The wireless module 110 may receive the connected antenna's identification (205). The reception of the identification, e.g., the unique identifier, may be the result of a request sent by the wireless module 110, or may be received without a request from the wireless module from the antenna module (e.g., upon power up, or at a predetermined interval, or the like). The wireless module 110 can use the unique identifier for any number of purposes, for example to verify that the antenna connected is an appropriate antenna (210) that will operate within the range, within the limits, and/or with the performance specified for the radio circuits within the wireless module 110. This may be accomplished, for instance, by ensuring that the unique identifier matches an expected number or is within a predefined or approved range of unique identifiers, for example a range of serial numbers. The unique number of set of unique numbers that are expected or approved may be pre-determined based upon earlier testing and may be programmed into the wireless module 110. In some examples, the set of unique numbers that are expected or approved may be updated by an external computing device. Thus for example, if additional antennae are tested and found to operate within the range, limits, or performance required, the serial numbers (or range of serial numbers) for that antennae may be added to the approved list of devices.
Additionally, in another example embodiment, the unique identifier can be categorized in various ways (even or odd, modulo (n) (the remainder when divided by a number ‘n’), and the like), and be used to distinguish between one or many types of compliant antennas. Example antennas may include dipole, slot, monopole, loop, patch, and PIFA (planar inverted F) antenna types. These antennas may have applications in tablet computers, notebook computers, cellular telephones, smart phones, Frequency Modulation (FM) radios, Amplitude Modulation (AM) radios, televisions, or any other application in which an antenna is used to receive electromagnetic waves. The techniques presently disclosed allows for regulatory compliance of these antennas to be ensured and/or for changes to various parameters to be made so as to ensure compliance or optimal performance. If the antenna is a compliant antenna 225, then no further action may need to be taken.
According to another example embodiment, also illustrated in FIG. 2, if (215) the antenna module 110 does not respond with the correct unique identifier, however determined by the wireless module 110, the module 110 will react with appropriate action (220), for example as may be programmed in the wireless module. For example, the wireless module may throttle its power or disable itself in order to minimize the risk of functioning outside of its approved parameters (e.g., in violation of United States FCC Regulation Part 15). For instance, transmission power can be reduced, when a high gain antenna is indicated by the identification, while the transmission power can be enhanced when a weaker omni antenna is indicated by the identification.
In another embodiment illustrated in FIG. 3, the wireless module 110 may receive the identification of the connected antenna (305), identify the antenna (310), and use the acquired identity of the antenna to optimize various wireless configuration parameters (315). In some examples, each antenna identification number or a range of identification numbers may be associated with a parameter profile. The parameter profile may include one or more parameter changes to the wireless module. Example parameter changes may include: the power level, frequency, or firmware configuration. Each target device in which the antenna is to be integrated may have a different unique identifier programmed into the connected antenna 100. Each different device may require different tuning based upon the different impedance characteristics of the device. Identifying the unique identifier of the antenna will allow the wireless module 110 to optimize the wireless configuration parameters to best suit the particular device in which it is installed. In some examples, to accomplish this, the wireless module may load a specific configuration of firmware or tunable/switchable matching components. This allows for operation at a desired efficiency, such as a defined optimum or maximum efficiency. Various example end products may include laptops, mobile devices, other consumer products, industrial devices, household appliances, control system components, or the like.
According to one example embodiment, the antenna management functions described with respect to the figures described above and below herein, are performed by the baseband chip 120, which, in one embodiment, includes microprocessor system components 121 capable of executing one or more computer programs configured to carry out the described methodologies, and/or other programmable circuit components that are configured to acquire the unique identifier 107, and perform any of the management functions herein described, including applying control signals or configuration parameters to other internal circuits of the baseband chip 120 or to the RF chip 115. In other examples, the antenna management functions may be performed by the RF chip 115, or other microprocessors or control logic present on the wireless module 110. In still other examples, the antenna module 100 may contain a microprocessor which may receive an expected identification number, range, or other indicator and make the necessary adjustments at the antenna side or communicate the necessary adjustment to the wireless module 110. Alternatively, the antenna ID can be forwarded to a computing platform separate from the wireless module 110, such as the microprocessor board and associated components of a computing system in the device on which the wireless module 110 is deployed. The management functions are then performed on the separate computing system and control and configuration signals applied back to the wireless module 110.
In one embodiment, for example, the device 105 may be a Maxim DS2401 one wire protocol chip, available from Maxim Integrated Products, Inc., of Sunnyvale, Calif. The DS2401 is an enhanced “silicon serial number” providing a low-cost, electronic registration number that provides an absolutely unique identity that can be determined with a minimal electronic interface, typically, a single port pin of a microcontroller. The DS2401 includes a factory-lasered, 64-bit ROM that includes a unique 48-bit serial number, an 8-bit CRC, and an 8-bit Family Code (01h). Data is transferred serially via a 1-Wire®-type protocol that requires only a single data lead and a ground return. Power for reading and writing the device is derived from the data line itself with no need for an external power source. The DS2401 is fully reverse-compatible with the DS2400 but provides an additional multi-drop capability that enables many devices to reside on a single data line. In other embodiments, any device or chip providing serial number identification capabilities may be used, such as other wireline chips, radio frequency identification (RFID) chips, bar coded chips, or any other devices having similar or different serial number identification capabilities.
According to another example embodiment illustrated in FIG. 4, the antenna module 100 and wireless module 110 are used on a desktop computer 400 having a chassis 402. In this embodiment, the serial number device 105, for example the DS2401, is supplied with a power signal 405 and shares the ground 410 with the antenna 415. The control signal 430 for the serial number device 105 may be sent from the wireless module 110 over the center conductor 435 of a coax cable 440 connecting the antenna to the module through the use of a Bias-T 445. In the antenna module 110, another Bias-T 450 is used to separate the low frequency control signal from the RF signal 455, which is routed to the antenna feed 460. Additional cables to supply the identification device are thus kept to a minimum.
According to another example embodiment illustrated in FIG. 5, the antenna module 100 and wireless module 110 are used on a laptop, notebook, tablet PC or another other computing device or computer 500 having case 502. In this embodiment, the antenna module(s) 100 is embedded inside the case of the laptop, in this example on a hinged cover 503 of the device. Otherwise, the configuration of FIG. 5 is similar to the configuration of FIG. 4.
According to another example embodiment illustrated in FIG. 6, a single baseband chip 120 and intermediate frequency chip may interface with one or more remote RF chips 615. In these examples, the antenna array is part of, or connected to, the RF chip. In some examples, these antenna modules 600 may operate at 60 GHz, and utilize phased antenna arrays. These antenna modules 600 require detailed calibration parameters pertaining to the calibration and operation of the antenna array 620 to be employed based upon the exact RF remote chip 615 and the particular influence of the chassis that hosts the RF chip. In some examples, the same SKU (Stock Keeping Unit) of the base band chip 120 may be configured to control multiple different RF remote chips 615. By utilizing the remote RF chip 615 to store a unique identifier identifying the exact antenna array and the particular host chassis, the base band chip may configure the remote RF module embedded in the chassis accordingly. In addition, the cost is reduced as an additional chip to store the unique identifier is not required as the RF chip 615 may be utilized.
Accordingly, with use of the antenna identification and management system herein described, it is not necessary to use obscure or difficult to procure connectors to make it harder to connect aftermarket antennas that may make the wireless solution non-compliant. These connectors can be many times more expensive compared to a generic, easy to find connector. Additionally, for embedded antennas connected to tuner modules, the ready ability to load predefined profiles based on different antenna types is advantageous. The tuning profiles are typically developed for one specific antenna model, and the ability to match the profiles automatically assures good performance and in some cases greater ease or lesser risk of mismatch of antenna to the module during assembly.
Thus, as described above, the present solution uses a serial number chip to associate each antenna with a unique identifier that can be queried by either the module or the host. With the knowledge of the exact antenna connected to it, the module 110 can determine its behavior, transmission and matching settings to optimize performance while maintaining regulatory compliance. Also, non-compliant antennas may result in the module lowering the output power delivered or disabling itself to minimize the risk of operating in a non-compliant state. When used with embedded antennas for laptops, the invention allows for the optimized matching between a module and any one of several types of antennas by allowing the module to alter its configuration to match a particular antenna type without requiring the maintenance of several custom SKUs for each antenna type.
According to one example embodiment, any of the above or below described software or hardware elements and functionality, may be implemented as a combination of one or more modules, as defined further herein below. Further, various methods or techniques, or certain aspects or portions thereof, may take the form of program code (i.e., instructions) embodied in tangible media, such as floppy diskettes, CD-ROMs, hard drives, or any other machine-readable storage medium wherein, when the program code is loaded into and executed by a machine, such as a computer, the machine becomes an apparatus for practicing the various techniques. In the case of program code execution on programmable computers, the computing device may include a processor, a storage medium readable by the processor (including volatile and non-volatile memory and/or storage elements), at least one input device, and at least one output device. One or more programs that may implement or utilize the various techniques described herein may use an application programming interface (API), reusable controls, and the like. Such programs may be implemented in a high level procedural or object oriented programming language to communicate with a computer system. However, the program(s) may be implemented in assembly or machine language, if desired. In any case, the language may be a compiled or interpreted language, and combined with hardware implementations.

The storage device 816 includes a machine-readable medium 822 on which is stored one or more sets of data structures and instructions 824 (e.g., software) embodying or utilized by any one or more of the methodologies or functions described herein. The instructions 824 can also reside, completely or at least partially, within the main memory 804, static memory 806, and/or within the processor 802 during execution thereof by the computer system 800, with the main memory 804, static memory 806, and the processor 802 also constituting machine-readable media.
While the machine-readable medium 822 is illustrated in an example embodiment to be a single medium, the term “machine-readable medium” can include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) that store the one or more instructions 824. The term “machine-readable medium” shall also be taken to include any tangible medium that is capable of storing, encoding or carrying instructions for execution by the machine and that cause the machine to perform any one or more of the methodologies of the present disclosure or that is capable of storing, encoding or carrying data structures utilized by or associated with such instructions.

The instructions 824 can further be transmitted or received over a communications network 826 using a transmission medium via the network interface device 820 utilizing any one of a number of well-known transfer protocols (e.g., HTTP). Examples of communication networks include a LAN, WAN, the Internet, mobile telephone networks, Plain Old Telephone (POTS) networks, and wireless data networks (e.g., Wi-Fi, 3G, and 7G LTE/LTE-A or WiMAX networks).

The embodiments described above may be implemented in one or a combination of hardware, firmware, and software. Embodiments may also be implemented as instructions stored on a computer-readable storage device, which may be read and executed by at least one processor to perform the operations described herein.

For example, a computer-readable storage device may include read-only memory (ROM), random-access memory (RAM), magnetic disk storage media, optical storage media, flash-memory devices, and other storage devices and media. In some embodiments, the base station or the UE may include one or more processors and may be configured with instructions stored on a computer-readable storage device.
It should be understood that the functional units or capabilities described in this specification may have been referred to or labeled as modules, in order to more particularly emphasize their implementation independence. For example, a module may be implemented as a hardware circuit comprising custom VLSI circuits or gate arrays, off-the-shelf semiconductors such as logic chips, transistors, or other discrete components. A module may also be implemented in programmable hardware devices such as field programmable gate arrays, programmable array logic, programmable logic devices, or the like. Modules may also be implemented in software for execution by various types of processors. An identified module of executable code may, for instance, comprise one or more physical or logical blocks of computer instructions, which may, for instance, be organized as an object, procedure, or function. Nevertheless, the executables of an identified module need not be physically located together, but may comprise disparate instructions stored in different locations which, when joined logically together, comprise the module and achieve the stated purpose for the module.
Indeed, a module of executable code may be a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs, and across several memory devices. Similarly, operational data may be identified and illustrated herein within modules, and may be embodied in any suitable form and organized within any suitable type of data structure. The operational data may be collected as a single data set, or may be distributed over different locations including over different storage devices, and may exist, at least partially, merely as electronic signals on a system or network. The modules may be passive or active, including agents operable to perform desired functions.
Additional examples of the presently described method, system, and device embodiments include the following, non-limiting configurations. Each of the following non-limiting examples can stand on its own, or can be combined in any permutation or combination with any one or more of the other examples provided below or throughout the present disclosure.
