First Claim
1. A method comprising:
- receiving, at a location tracking device, a request to identify the location tracking device;
transmitting a response identifying the location tracking device;
receiving, via a wireless communication, a silence command at the location tracking device, the silence command instructing the location tracking device to stop all wireless transmissions;
transmitting a message indicating that the location tracking device entered a radio silence mode at a certain time;
stopping all wireless transmissions from the location tracking device for a pre-specified period of time in response to the silence command;
determining at the location tracking device that the pre-specified period of time has elapsed; and
resuming wireless transmissions from the location tracking device in response to the determination that the pre-specified period of time has elapsed.

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.
