1. A wireless active suspension system comprising:
at least one sensor mounted to an unsprung mass of a vehicle, said at least one sensor comprising a low-power wireless communication capability,
said at least one sensor to send a sensor data transmission, wherein said at least one sensor utilizes an enhanced shockburst (ESB) protocol for said sensor data transmission, said at least one sensor having a receiver, said at least one sensor having a dormant state, said at least one sensor periodically exiting said dormant state to determine if there is movement of said vehicle; and
a controller in wireless communication with said at least one sensor, wherein said controller receives said sensor data from said at least one sensor, and communicates an adjustment command to modify at least one damping characteristic of at least one damper coupled to said vehicle, said at least one sensor configured to only activate said receiver after said at least one sensor has sent said sensor data transmission to said controller.
