Abstract
An apparatus and method is provided for transparent communication between a wireless remote or mobile device and a fixed wired communication host network. The apparatus and method may include a remote network controller that logically resides between the host network and the existing radio infrastructure(s) that are used to provide wireless contact with one or more remote devices. The remote network controller is connected to the host communication network as a protocol-appropriate communications controller so that remote devices are indistinguishable to the host network from the locally-attached devices. Each remote device may be provided with an asynchronous serial data interface to communicate with a mobile data controller. The mobile data controller, in combination with the remote network controller, provides end-to-end data communication such that incompatible protocols are transparent to the remote device and host communication network.
