Abstract: A system and method perform wireless networking that allows a cellular phone user to invite and share conversations with other cellphones or wireless communication devices in local spatial proximity by means of a wireless mesh or infrastructure or an ad-hoc network. In the system and method, there is no per-minute cost by using wireless local area networks in the unlicensed spectrum, such as a 802.11 network. Conversations are shared with only the intended persons. To join a conversation using the method, users only require any wireless device, and not necessarily a cellphone, such as a laptop with wireless capability.
