TPMS(Tire Pressure Monitoring System) using the wireless communication technique is defined as the safety aid system to efficiently realize and manage the condition of tires in the vehicle. The wireless communication system of TPMS should suffers from various noise and interferences such as signals of each tire sensor or outside electrical equipments. In order to retain the data reliability of TPMS, we propose an assessment method of the data reliability based on signal-to-interference and noise ratio (SINR) of the received signal. The proposed technique can be widely applied to wireless duplex communication systems based on various sensors. We verify critical SINR values to satisfy data reliabilities of 95%, 97%, and 99% through computer simulation.
