Abstract
A method and system for multi-stage media communications a means for transmitting and receiving media messages via a two-stage communications protocol and a means for relaying the media messages via the two-stage communications protocol to one or more additional means for transmitting and receiving. The two-stage communications protocol includes a first RF-based stage and a second IP-based stage. The second IP-based stage uses SIP for establishing media communications between the means for transmitting and receiving media messages. Preferably, the system includes one or more wireless handheld devices for sending and receiving media and a base station device for relaying such media. Additional base stations can be added (via an IP network) to increase communications range without complex networking infrastructure.
