The present application is at least directed to a beacon device including a non-transitory memory with instructions stored thereon for communicating with an endpoint device in an environment. The apparatus also includes a processor, operably coupled to the non-transitory memory, configured to execute the instructions of determining, via global positioning system (GPS), coordinates of the beacon device in the environment. The processor is also configured to execute the instructions of storing the coordinates in the non-transitory memory. The processor is further configured to execute the instructions of disabling the GPS. The processor is even further configured to execute the instructions of broadcasting, to the endpoint device, information including a beacon ID and the stored coordinates via an encrypted message.
