20080287071 | EXPANDABLE WIRELESS TRANSCEIVER - An expandable wireless transceiver is provided. The expandable wireless transceiver includes an antenna, a receiver, a transmitter and a switch connector. The antenna detects an electromagnetic signal in surrounding space and receives a signal with a first central frequency according to the detection result.
