I would like a device that looks and works like a walkie-talkie except\nit communicates with a wireless 802.11g Access Point and uses voice\nover IP to transmit voice communications over a WAN. I believe that\nthis would have several benefits over a conventional cell phone, i.e.\nno monthly charges, in some cases clearer communications, improved\nsecurity. To make a call to another walkie-talkie on the WAN you could\ntype in the IP address for that device. The device should be\nlightweight, small, and can easily be carried on a person. Does a\nproduct like this exist?
