Abstract
A system and method switches a mobile device from a first wireless communication signal, to a second, different wireless communication signal to maintain or reestablish communication between the mobile device and a communication network. Switching occurs when the signal strength of the first wireless communication signal falls below a predefined threshold and a second communication signal is present.
