Abstract

The present invention is directed to a system and method for sending and receiving Voice-over-Internet-Protocol over a wireless computer network utilizing a hybrid wireless voice-over-Internet-Protocol telephone. The invention utilizes a phone controller (302), a wireless handset (100), a base station (310) and at least one access point (304). The wireless handset is equipped with both a wireless personal area network transceiver and a wireless local area network transceiver. The base station (310) is equipped with a wireless personal area network transceiver and a network interface card. Voice-over-Internet-Protocol packets are routed to the phone controller (302) which forwards the packets to either the access point (304) for transmission to the wireless handset (100) over the wireless local area network (306,304,316), to the base station (310) for transmission to the wireless handset (100) over the personal area network (314), or to a server for transmission out of the local area network. The wireless personal area network can be based upon Bluetooth or IrDA

25. The method of claim 24 wherein the second transceiver is a higher powered transceiver than the first transceiver.
26. The method of claim 24 wherein the first transceiver is a Bluetooth compatible transceiver.
27. The method of claim 26 wherein the second transceiver is an 802.11 compatible transceiver.
28. The method of claim 27 further comprising re-establishing the connection with the base station via a first transceiver when the wireless handset returns to being within range of the base station.
29. The method of claim 28 further comprising switching power off to the second transceiver after re-establishing the connection with the base station.
30. A method for a base station to facilitate communications between an associated wireless handset and a local area network, the steps comprising:
