Abstract

A gateway adapted to receive data from a device of a local area network is described herein. In some embodiments, the gateway may be adapted to multiplex received data to another device among multiple wide area networks, wherein at least one of the wide area networks is a wireless wide area network. The gateway may have a wireless wide area networking interface and at least one of one or more other wireless wide area networking interfaces and/or one or more wired wide area networking interfaces, the wired and/or wireless networking interfaces each adapted to transmit data to at least one of the multiple wide area networks. In other embodiments, the gateway may be adapted to transmit the received data to the other device through a preferred wide area network, and, if that network is unavailable or operating conditions determine otherwise, transmit the received data to the other device through a back-up wide area network.
