An end point (EP) device may communicate with multiple gateways via wireless signals, e.g. wireless broadcast signals. An EP device is controlled, under the direction of a control server, e.g., an application server, to communicate via a single gateway. The control server associates the EP device with a single target gateway and/or uses EP transmission power control training iterations to reduce the EP transmission power level until the EP device is only able to successfully communicate its wireless signals to a single gateway.
