Abstract: A portable transreceiver system transmitting voice communications over a data network is described. The system has a portable transreceiver (WT) mode where multiple users are connected using semi duplex communications, and a private mode in which pairs of users are connected using full duplex communications. Wireless voice enabled terminals are used by the users, and are interconnected via a network such as the Internet.

Abstract: Described below is a system to provide voice communication over a data network. The system is described as an access point connected to the data network adapted to exchange network messages over the data network and a wireless terminal including a transmitter component and a software module, the transmitter component adapted to exchange wireless messages with the access point over a wireless network, and the software module configured to provide a plurality of virtual channels. Each of the virtual channels being carried over the wireless network and the data network, the software module being configured to enable reception of the voice communication and to enable transmission of the voice communication over selected virtual channels.
