A wireless telecommunications system base station architecture is disclosed that supports receive diversity, sectorization, and radio pooling without the need for a sniffer radio or a switching matrix between the radios and the receive antennas. An illustrative embodiment of the present invention comprises: a first receive antenna for receiving a first incoming signal; a second receive antenna for receiving a second incoming signal; a first transmit antenna for transmitting into a first sector; a second transmit antenna for transmitting into a second sector; a first switch for receiving a first outgoing signal and a first control signal, and for routing the first outgoing signal to at least one of the first transmit antenna and the second transmit antenna based on the first control signal; and a first radio for receiving the first incoming signal from the first receive antenna and the second incoming signal from the second receive antenna, and for providing the first outgoing signal and the first control signal to the first switch.
