Abstract
A method and system for adaptively allocating bandwidth in an electronic toll collection system. The system includes a reader that adapts the scanning time allocated to specific antennas based upon the traffic conditions. Those antennas that process a higher volume of traffic receive a greater allocation of the scanning time. In some embodiments, the determination as to when to allocate additional time to an antenna may be based upon whether or not a transponder is currently in the coverage zone for the antenna.
