An apparatus for cooperating with a mobile device having an embedded transceiver is disclosed. The apparatus includes a housing and a mechanical connector on the housing, the mechanical connector being configured to mechanically retain the mobile device. At least one port within the housing conveys energy to at least one auxiliary wireless transceiver associable with the apparatus. The apparatus is configured to cooperate with the mobile device when the mobile device is retained on the housing by the mechanical connector, to enable transmission of a first portion of a data stream over the at least one auxiliary transceiver while a second portion of the data stream is simultaneously transmitted over the embedded transceiver.
