Abstract

In a wireless class-based data communications network, a class-switching method includes configuring a wireless two-way RF data communication device, of a wireless class-based data communications network, to adopt a different class designation of another wireless two-way RF data communication device of a proximate wireless class-based data communications network such that the particular wireless two-way RF data communication device joins the proximate wireless class-based data communications network. Another class-switching method includes communicating a command to a wireless two-way RF data communication device of a wireless class-based data communications network to change its class designation to that of another wireless two-way RF data communication device of a proximate wireless class-based data communications network such that the wireless two-way RF data communication device joins the proximate wireless class-based data communications network.
