Abstract
The present invention addresses a problem that switching antennas along with an unexpected variation of a received electrical field strength brings about a loss over a long period of data transmission. According to a wireless LAN transceiver in which the present invention is implemented, when a data throughput attained by an application layer poses no problem, switching antennas is disabled. Consequently, the data throughput can be kept satisfactory. Namely, since whether the antennas are switched is not determined with an unexpected variation of an RSSI signal or an error rate in a lower layer, unnecessary switching of the antennas can be prevented. A loss derived from the switching of the antennas can be minimized over a long period of time.
