Abstract

An apparatus has first and second wireless communication modules with respective first and second wireless communication signaling terminals. An arbiter is coupled to receive a request for access to an antenna from one of the first and second wireless communication modules. The arbiter is operable to cause the antenna to be coupled to one of the first and second wireless communication signaling terminals in response to the request, and a coexistence module is operable to prevent the arbiter from receiving a request from the second wireless communication module to thereby allow a communication of the first wireless communication module.
