Abstract
This paper presents a new means of communication for remote meter reading system which uses CDMA data service. The system has made good use of CDMA features like permanent being online, timely transmitting, and charging based on traffic rather than time. Using CDMA technology for remote meter reading system will not only greatly improve stability, reliability and timeliness of the system, but also significantly reduce the costs of the system operating. To ensure the safety and integrity of the energy consumption data, we proposed a new protocol that composed by dynamic authorization component and encryption component. The system uses a CDMA module named MSP430F149 to login into the CDMA network, which enable the system to transmit data wirelessly..
