Abstract

A modular cellular wireless communication base station includes a plurality of active radiator modules located at a desired antenna location. Each module includes at least one antenna, a transmitter, and a receiver. A beam forming network controls relative amplitudes and phases of each of the modules. An RF front end transmits over a low power link with the active radiator modules via the beam forming network and receives over the low power link via a low noise amplifier. A delay diversity module provides a transmission CDMA delay diversity.

Claims

1. A repeating device comprising:

a donor antenna for linking to a transmitting antenna of a base station;

two orthogonally polarized donor antennas for linking to two orthogonally polarized receive antennas of said base station;

a subscriber-side antenna for linking to at least one mobile transceiver;

two orthogonally polarized subscriber-side antennas for linking to said at least one mobile transceiver;

a first amplifier, connected between said donor antenna and said subscriber-side antenna, for amplifying a signal received by said donor antenna prior to transmitting said signal via said subscriber-side antenna;

a second amplifier, connected between one of said orthogonally polarized donor antenna and one of said orthogonally polarized subscriber-side antenna, for amplifying a signal received by said one orthogonally polarized subscriber-side antenna prior to transmitting said signal via said one orthogonally polarized donor antenna; and

a third amplifier, connected between the other of said orthogonally polarized donor antenna and the other of said orthogonally polarized subscriber-side antenna, for amplifying a signal received by said other orthogonally polarized subscriber-side antenna prior to transmitting said signal via said other orthogonally polarized donor antenna.

2. A repeating device comprising:

two orthogonally polarized donor transmit antennas, for linking to two orthogonally polarized receive antennas of a base station;

two orthogonally polarized donor receive antennas, for linking to two orthogonally polarized transmit antennas of said base station;

two orthogonally polarized subscriber-side transmit antennas, for linking to at least one mobile transceiver;

two orthogonally polarized subscriber-side receive antennas, for linking to said at least one mobile transceiver;

a first amplifier, connected between one of said orthogonally polarized donor transmit antenna and one of said orthogonally polarized subscriber-side receive antennas, for amplifying a signal received by said one orthogonally polarized subscriber-side receive antenna prior to transmitting said signal via said one orthogonally polarized donor transmit antenna;

a second amplifier, connected between the other of said orthogonally polarized donor transmit antenna and the other of said orthogonally polarized subscriber-side receive antennas, for amplifying a signal received by said other orthogonally polarized subscriber-side receive antenna prior to transmitting said signal via said other orthogonally polarized donor transmit antenna;

a third amplifier, connected between one of said orthogonally polarized donor receive antenna and one of said orthogonally polarized subscriber-side transmit antennas, for amplifying a signal received by said one orthogonally polarized donor receive antenna prior to transmitting said signal via said one orthogonally polarized subscriber-side transmit antenna; and

a fourth amplifier, connected between the other of said orthogonally polarized donor receive antenna and the other of said orthogonally polarized subscriber-side transmit antennas, for amplifying a signal received by said other orthogonally polarized donor receive antenna prior to transmitting said signal via said other orthogonally polarized subscriber-side transmit antenna.
