Abstract
A tire pressure monitoring system where the position and orientation of a receiver antenna associated with the tire pressure monitoring system is at a location that is proximate the tire pressure monitoring system. In one embodiment, the receiver antenna is positioned beneath a vehicle chassis. The location of the receiver antenna can be determined by system performance prediction tools that include mean-time-to-warning verses packet error rate curves for a desired packet error rate and packet error rate verses signal-to-noise ratio curves for various operational scenarios and different classes of vehicle that provides a necessary signal-to-noise ratio for a wireless link, and operational scenarios that established desired levels of performance and reliability.
