Abstract

A wireless communication device includes conventional components to permit a network communication link to be established with a wireless communication network. In addition, the wireless communication device includes a non-network short-range transceiver that detects the presence of other similarly equipped devices. When two such equipped devices come within proximity of each other, a direct non-network wireless communication link is established.
