Abstract
A system and method for selecting a best transmit antenna for a transceiver using antenna diversity that caches the identity of the best transmit antenna for each remote node from which a message has been received. The best transmit antenna is then selected for each message sent to a remote node having a cache entry.
Claims8
A method for selecting a transmitter in a diversity antenna transceiver, with the transceiver including a receive antenna selection feature that selects a receive antenna based on best signal quality of a signal received from a remote node, said method comprising:
- storing an indication of a best antenna for each remote node from which a message has been received;
- examining a message to be transmitted to determine the target remote node which is the destination of the message;
- and
- utilizing the best antenna indicated for the remote node if an indication of the best antenna for the remote node has been previously stored.
