Abstract

A wireless communication device detects presence of a peer wireless communication device within operating range and pairs with the detected peer wireless communication device. The wireless communication device and the peer wireless communication device are operable to communicate wireless broadband signals at a power level that is below a spurious emissions mask using broadband near field communication with full spectrum capture. The pairing may be controlled based on the determined distance between the wireless communication device and the peer wireless communication device. A determination is made whether to utilize security to enable the pairing based on the determined distance. A range of the communicated wireless broadband signals may be limited to provide secure communication between a plurality of wireless communication devices that communicate utilizing the wireless broadband signals. Content is shared among the plurality of wireless communication devices based on the limiting.
