An application of CDMA technique to a dedicated data collection system for monitoring and control of city lifelines is considered. This paper describes the system configuration of a 2.4 GHz experimental system in which CDMA is combined with polling technique to access 256 household terminals. Results of preliminary experiments are also presented.
