Abstract: The present mobile social networking assembly establishes new connections between users within the network of proximity created by the assembly and while the users mutually match the each others' data. The assembly implements a broadcast-based efficient/fast data exchange using minimal power via Dynamic Human Mobile Broadcast Networking without infrastructure demands. Implemented within a mobile telephone or as a stand-alone unit (10) for use with a mobile telephone (18), the assembly efficiently exchanges user data with other social networking assemblies and notifies users of data matches via existing mobile telephone networks (30). Power saving mechanisms include minimizing redundant data transfer and synchronizing the data exchange between users to allow broadcast sleep mode usage.
