Abstract

Described is a device and method for optimizing communications in a wireless network. The device comprises a first wireless transceiver communicating using a first channel of a first frequency band, a second wireless transceiver communicating using a second channel of a second frequency band, and a processor selecting one of the first and second transceivers for transmission of a wireless signal to a further device as a function of destination data of the further device. The further device includes a third transceiver communicating using one of the first and second frequency bands.

Claims
