These transceivers may include a first transceiver to communicate wirelessly across cellular links, and a second transceiver to communicate wirelessly across wireless data networking links. The apparatus may also include controllers, each controlling wireless communications of a corresponding transceiver. Information may be exchanged with each other regarding operation of the transceivers. Through the exchange of such information, activity (e.g., transmission and reception of wireless signals) may be coordinated among the transceivers.
