Abstract

An integrated wireless transceiver is described. The integrated wireless transceiver may include a radio, a frequency converter coupled to the radio, a switch coupled to the frequency converter, and at least one antenna coupled to the frequency converter. The radio may be configured to convert a first signal from a baseband to a first band of frequencies and to convert the first signal into a first transmit signal in accordance with a wireless local area network (LAN) communications protocol. The frequency converter may be configured to convert the first transmit signal from the first band of frequencies to a second band of frequencies. The second band of frequencies may correspond to a band of frequencies that is different than one or more bands of frequencies associated with the wireless LAN communications protocol.
