Inclusion of a Tire Pressure Monitoring System (TPMS) in a vehicle presents a new design challenge in terms of automotive electrical system integration. This paper examines the dynamic RF signal path characteristics of a TPMS data link operating at 315MHz as a short-range device Electromagnetic modeling results and anechoic chamber measurements provide signal path loss estimates for various system configurations. A qualitative link budget formulation is proposed that accounts for observed dynamic and quasi-static variation of the TPMS signal.
