An arrangement of logically distinct wireless data communication networks share a gateway for communicating with external networks. Each logically distinct network preferably is a class-based network, the nodes of which include a wireless two-way radio frequency data communication device. Each device filter wireless communications received by it for an identification within the communication of its class designation, or for a class, abstract class, or subclass corresponding to its class designation; and process the communication if found and do not process the communication if not found. The gateway wirelessly communicates with each logically distinct network by including the respective class designation for the network with which the communications are desired. The other class based networks do not process messages that are communicated to the desired class-based network, thereby avoiding unnecessary power consumption by the wireless devices.
