Patent ID: 8508341

Claim:
An adaptive communication system for communicating with a transponder located in a moving vehicle travelling on a roadway, the transponder having a transponder memory to store configuration type data, the system comprising: at least one antenna having a coverage area that includes at least a portion of the roadway, the at least one antenna to receive an RF signal modulated by the configuration type data from the transponder memory; a system memory having a database stored thereon, the database listing at least one predetermined communication parameter for each of at least two types of configurations; and a control device connected to the at least one antenna and the system memory, the control device to demodulate the RF signal to obtain the configuration type data, to identify, based on the configuration type data, the predetermined communication parameters corresponding to the configuration type data, and to subsequently adjust at least one variable communication parameter based on the predetermined communication parameters identified based on the received configuration type data.
