Tire pressure monitoring system using wireless network

A tire pressure monitoring system comprising:

• a valve-stem mountable tire pressure gauge comprising:
• a pressure sensor adapted for detecting a pressure of a fluid in a tire, said pressure sensor providing an output signal indicative of the detected fluid pressure in the tire;
• and
• a first radio frequency module for transmitting data indicative of said detected fluid pressure based on said output signal of said pressure sensor;
• and
• a remote command device comprising:
• a second radio frequency module adapted for wirelessly receiving the data transmitted by said first radio-frequency module;
• a wireless communication module adapted for communicating, via a wireless network, information based at least on the data received by said second radio frequency module;
• and
• a display for displaying at least the fluid pressure detected by said pressure sensor,
• wherein the remote command device is configured to wirelessly receive a communication from a telecommunication device via the wireless network, said communication indicative of the identity of said telecommunication device, and to register the telecommunication device as a master telecommunication device, wherein said remote command device is responsive to a control signal transmitted by only said master telecommunication device.
