Abstract
A repeater for re-transmitting an incoming RF signal comprising: a first antenna array for receiving the incoming RF signal; a second antenna array for transmitting an outgoing RF signal; and a transceiver for down-converting the incoming RF signal to a down-converted signal, processing the down-converted signal, and up-converting the processed signal to produce the outgoing RF signal. The first antenna array is cross-polarized with respect to the second antenna array. The repeater also comprises an echo processor for attenuating in the down-converted signal an echo signal associated with the outgoing RF signal. The echo processor delays transmission of the outgoing RF signal in order to minimize the echo signal.
Claims20
A repeater for re-transmitting an incoming RF signal comprising:
- a first antenna array for receiving said incoming RF signal;
- a second antenna array for transmitting an outgoing RF signal;
- and
- a transceiver chain capable of down-converting said incoming RF signal to a down-converted signal, processing said down-converted signal, and up-converting said processed signal to thereby produce said outgoing RF signal, wherein said first antenna array comprises a first antenna element and said second antenna array comprises a second antenna element that is cross-polarized with respect to said first antenna element.
A wireless network comprising:
- a plurality of base stations capable of communicating with a plurality of mobile stations in a coverage area of said wireless network;
- and
- a repeater capable of re-transmitting forward channel signals from a first base station to a first mobile station and re-transmitting reverse channel signals from said first mobile station to said first base station, said repeater comprising:
- a first antenna array for receiving an incoming RF signal;
- a second antenna array for transmitting an outgoing RF signal;
- and
- a transceiver chain capable of down-converting said incoming RF signal to a down-converted signal, processing said down-converted signal, and up-converting said processed signal to thereby produce said outgoing RF signal, wherein said first antenna array comprises a first antenna element and said second antenna array comprises a second antenna element that is cross-polarized with respect to said first antenna element.
