Abstract

A charging device includes an integrated broadband transceiver that is operable to communicate wireless signals at a power level that is below a spurious emissions mask. The wireless signals are communicated over a designated frequency spectrum band via one or more antennas. The wireless signals convey data between the charging device and a communication device via one or more usable channels within the frequency spectrum band utilized by the integrated broadband transceiver. Concurrent with the communicating, charging of the communication device occurs. One or more usable channels within the frequency spectrum band utilized by the integrated broadband transceiver may be detected. The charging and the communication of the wireless signals occurs currently on the same ones or different ones of the one or more antennas. The detected one or more usable channels may be aggregated and utilized for the communication by the integrated broadband transceiver.
