A wireless communication device may receive with one of N antennas a signal processing message indicating a number up to N signals to process. Each of the N antennas may used to receive a communication. The indicated number of up to N signals may be processed and data from the indicated number of up to N signals recovered.

Multi-antenna communication in a wireless network

A wireless communication device may include processing modules and determine a hardware arrangement to facilitate performance for communication with a network. The hardware arrangement may include a first antenna or the first antenna and the second antenna, a first processing module and a second processing module, the first processing module including a single processing technique, the second processing module including first and second processing techniques. The first processing technique of the second processing module may be selected for the communication and adaptively selected to the second processing technique during the communication based on a cost.

Selecting modules for a wireless communication device

A method and apparatus for modifying functions in a wireless communication device are described herein. The wireless communication device may receive a selection that indicates a power or a signal processing functionality. The wireless communication device may then modify functions associated with a plurality of smart antennas based on the power or signal processing functionality and in relation to a reference design. The wireless communication device may then determine performance associated with the modified functions. The modified functions may, for example, include adjusting power of the smart antenna of the transmitter or receiver associated with the wireless communication device, adjusting power of the radio frequency (RF) chain of the transmitter or receiver associated with the wireless communication device, varying the number of antenna elements for transmissions or receptions, selecting a signal processing technique, or varying the power control algorithm.

Techniques for adapting a wireless communication device or system to support a desired functionality of the wireless communication system at an optimized performance and economic benefit are discussed. The desired functionality can be determined by defined criteria such as a maximum range of communication with the wireless communication system, quality of a transmission link in the wireless communication system, capacity of the wireless communication system, power consumption of the wireless communication system, protocols supported in the wireless communication system, modulation techniques used in the wireless communication system and processing techniques for combining signals in the wireless communication system. The system can be adapted by varying one or more of modules (e.g., components or processing techniques) used in the wireless communication system.

A method and system for inventorying wireless transponders, specifically referred to as RFID transceiver devices. To provide higher functionality, a microcontroller is used in the RFID, along with a battery, but the clock frequency of the microcontroller is adjusted, based on external input, to minimize battery requirements. The RFID transceiver device includes at least one sensor coupled to the microcontroller. Data from the at least one sensor is stored in non-volatile memory of the microcontroller if the battery is at a predetermined low level, and is read later when the battery is at a higher level.

The present invention relates to a system and method for providing security in an RFID system and provides a secure active RFID architecture that uses a combination of passive and active RFID circuitry and employs authentication and encryption techniques in the processing of data, at rest and over the air. In the method of communicating securely in an RFID system of the present invention, a random number is generated with the passive RFID circuitry. The random number is forwarded to a reader. The reader is authenticated by comparing a first hash value determined from a hash function of the random number generated at the RFID tag and an Authenticated Facility Group ID stored on the RFID tag with a second hash value determined from the hash function of the forwarded random number and an Authenticated Facility Group ID stored in the reader such that if the first hash value matches the second hash value the reader is authenticated. After the reader is authenticated, the tag ID stored at the RFID tag can be revealed. After authentication of the reader, a second layer of security using encryption is provided with the active RFID circuitry.

Method and system for an adaptive wireless communication system optimized for economic benefit

The present invention provides one or more powered wireless transponders and/or one or more passive wireless transponder devices communicating with a reader/interrogator and the method of efficiently inventorying these devices without the risk of eavesdropping. A reader transmits a random number and transponders generate their own random number. The transponders whose random number matches all or a part of the random number responds. If a collision occurs, the reader's random number can be changed and retransmitted until almost one transponder response is verified in a tree search algorithm. Specifically, the invention concerns a method for inventorying wireless transponders providing anti-eavesdropping anti-collision.

The present invention provides a method and system for establishing a highly mobile, long range secure wireless network with dynamic topologies and near full connectivity with acceptable latency using low cost, low power, compact and lightweight devices. One aspect of the system deals with a highly mobile network with dynamic network topologies and a time varying wireless medium that has neither absolute nor readily observable boundaries outside of which radio nodes are known to be unable to receive network frames, although the desirable open field boundary is 1 mile in radius from a base station node. A synchronous frequency hopping technique is used with mobile nodes that can become slave base station nodes to a master base station node to increase the effective range of the master base station without increasing the transmit power. Furthermore, the use of adjustable sleep times for the mobile nodes, as well as a novel clock calibration method, provides a substantial range increase with acceptable battery size and system latency.

The RFID system of the present invention provides activation of a subscription based device wirelessly using a RFID system. The system for activating of a user for a subscription service comprises a first secure RFID sensor associated with a subscription-based device and a second secure RFID sensor associated with a user device. The first and second secure RFID sensors communicate with one another to establish activation of the user device. For example, the first sensor can receive an authentication value associated with the subscription service from the second RFID sensor. After activation, the subscription-based device can broadcast the subscription service to the user device. Alternatively, the user device can also have a capability to verify its separate or related subscription such as WiFi, WiMAX, GSM, CDMA or other wireless-based connectivity service. Also, the user device associated with the subscription-based service can be activated only when a secure RFID sensor is within a predetermined range of the user device.
