Claim Text:
1. A wireless vehicle detection system comprising: one or more spaced-apart sensor pods positioned in close proximity to a plane of a surface of a road and to detect received communication signal strength, and operated to adjust transmitting power based upon the communication signal strength to thereby conserve power usage, each sensor pod including: (1) one or more vehicle detector controllers adapted to determine presence of one or more vehicles, (2) one or more communication controllers in communication with the vehicle detector controllers and adapted to communicate data relating to the presence of one or more vehicles, the one or more vehicle detector controllers and the one or more communication controllers each collectively having separate clock cycles and separately controlled sleep cycles for drawing power, (3) one or more batteries, (4) one or more circuits electrically connected to the one or more batteries to enhance protection of the one or more batteries from degradation at transmit power levels and enhance the life extension of the one or more batteries; and (5) one or more low profile antennas positioned within an enclosure of the sensor pod and adjacent an end portion of the enclosure, the one or more antennas being positioned to support one or more communication frequencies within a preselected radio frequency band; and a base station in communication with the one or more sensor pods to provide data processing and storage for the wireless vehicle detection system.
