ABSTRACT:
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.
