Abstract
A dual-mode router for conveying process communication packets across a plurality of distinct wireless process communication networks is provided. The router includes wireless communication circuitry and a controller coupled to the wireless communication circuitry. The wireless communication circuitry is configured to interact with signals from each of the plurality of distinct wireless process communication networks. The controller is configured to adapt process communication packets from a first distinct wireless process communication network for transmission over a second distinct wireless process communication network. Methods for configuring the distinct wireless process communication networks and relaying process packets over the distinct wireless process communication networks are also provided.
