A automatic meter reading system with OFDM--Based Power Line Communication Modem MAX2990 is presented. The system can collect data of water, electricity, gas and air-conditioning power consumption remotely from large-scale public buildings by using the CMS00A based on CDMA, and can supervise Real--timely environmental variables, such as temperature, humidity, wind speed and water flow rates and implement the corresponding control. Experimental data shows that the system has stronger anti--interference capabi...
