摘要： 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.

摘要： This invention provides a method and system for inventorying wireless transponders, specifically referred to as RFID transceiver devices. The RFID transceiver devices are certifiable by a recognized standards body, such as EPCglobal, or are compatible with recognized standards but have higher functionality than typical passive RFIDs, and yet are implemented with techniques that lower cost and battery requirements. Backscatter techniques of standard passive RFIDs are used to keep cost and battery requirements low. 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. In one embodiment, the microcontroller initially has a zero or near zero clock frequency. A comparator compares the received RF energy to a threshold, and when the threshold is exceeded, indicating the presence of a probe signal from an RFID reader, the microcontroller clock frequency is immediately increased, and further adjusted based on the received data. In an alternate embodiment, the clock frequency of the microcontroller is adjusted based on data from sensors, to keep the clock speed at the proper speed to adequately process the data while minimizing the power requirement of the microcontroller, and then create an input to modulate the backscattered signal to be transmitted by the RFID. The received data can also cause the microcontroller to request the sensors to generate sensing data at a faster rate, which in turn requires the microcontroller clock to increase to handle the increased sensor data. In an additional embodiment, multiple sensors are multiplexed to provide a single input stream to the microcontroller, reducing the microcontroller clock speed required, along with the overall cost of the microcontroller and sensors.

摘要： The present invention relates to use of a smart antenna for a RF reader on a Radio Frequency Identification (RFID) system to significantly increase the operating range of the RFID system. The smart antenna can be an adaptive antenna array. The smart antenna comprises a plurality of antenna elements and, by combining the signals from multiple antenna elements, significantly increases the received signal-to-noise ratio. In a noise limited environment, combining the signals to maximize the received signal-to-noise ratio can be based on the maximal ratio combining (MRC) principle. To achieve the best signal quality, the received signal from each antenna can be phase-shifted such that the resultant signals from all antennas are in phase. In addition, the signal from each antenna can be scaled in amplitude based on the square root of its received signal-to-noise ratio.

摘要： A smart external antenna module is proposed for wireless systems. The module allows the advantages of smart antennas to be easily added to existing wireless systems without any modification to the transceiver. Specifically, the smart antenna module weights and combines the signals received by multiple antennas to improve the received signal quality, and then when it detects that there is a signal to be transmitted by the transceiver, it turns off the receiver, turns on the transmitter and uses the receive weights to transmit the signal out of the multiple antennas to improve signal reception at the desired user. Such a module can be added to the external antenna port of an existing transceiver with no change to that transceiver.

摘要： The present invention provides a method and system for operating a wireless communication system in which received signals from a plurality of antennas are weighted and combined with a beam forming operation to form an output signal. The beam forming operation determines weights adjusted to increase a desired signal power in the output signal while reducing the power in the output signal of out-of-band components. In an embodiment of the present invention, beam forming operations are performed with maximal ratio combining (MRC). Alternatively, a constant modulus algorithm (CMA) can be used for beam forming operations. In an alternate embodiment, improved interference suppression is performed with a novel algorithm referred to as an interference nulling algorithm (INA). The INA receives an error signal which is 180° out of phase with a combination of the channels for individual antennas, referred to as the SUM channel. The error signal is determined by complex conjugate multiplication of the individual signals and a reference complex signal. It is desirable to simultaneously achieve diversity and combining gain and suppress the adjacent channel by combining the weight generation for MRC and that for INA, as described above, to generate antenna weights similar to those of MMSE combining.
