Abstract
A method includes receiving a silence command at a location tracking device, where the silence command instructs the location tracking device to stop wireless transmissions. The method also includes stopping wireless transmissions from the location tracking device for a specified period of time in response to the silence command. The method further includes automatically resuming wireless transmissions from the location tracking device after the specified period of time has elapsed. A length of the specified period of time can be defined by the silence command. A request to identify the location tracking device can be received at the location tracking device, and a response identifying the location tracking device can be transmitted prior to receiving the silence command.
