Abstract
A transceiver system for RF communications in a wireless network includes a transceiver having first and second receivers and a transmitter. The first receiver and transmitter are connected to first antenna section. The second receiver is switchable between connection to a second antenna section and connection to the first antenna section. In a dual diversity mode, the second receiver is connected to the second antenna section, and the two receivers are tuned to the same RF channel set. Thus, multi-path faded signals in the RF channel set are received at the two antenna sections. In a cross-connected mode, two of the transceivers are used together, with the second receiver in each being connected to the first antenna section. Each transceiver supports one antenna, and the receivers in each transceiver (as well as the transmitters) are respectively tuned to different RF channel sets. Thus, system capacity is doubled in conjunction with diversity reception.
