Abstract
A wireless system includes at least one network computing system, a proxy server, a controller, and wireless devices. When a wireless device is already a member of a first group but moves into range of a second group, that device may initiate a request to join the second group, thereby ensuring that the wireless device can send and receive information through the second group. The proxy server maintains a list of authorized wireless devices and their primary controller, thereby routing information from one or more network computing systems to the proper controller, so that the wireless device may receive information from one of those network computing systems as necessary. When the wireless device becomes joined to a new controller, the proxy updates its list, thus ensuring continuity between the wireless device and the one or more network computing systems.
