Distribution automation using CDMA

Distribution automation technology using code division multiple access (CDMA) wireless communication network had been developed and proved its cost effectiveness and durability through the field test. Several system components for CDMA such as gateway, packet assembly disassembly (PAD) and modem had been newly developed and their interfaces are standardized. Establishing a separate control channel for Inter-Working function (IWF) from central station, system reliability is significantly improved in the case of event processing. CDMA network would be applied to a small-scale DAS which has a difficulty to construct a communication network in an economic way, while fiber optic cable would be applied to a large- scale DAS which needs high speed and reliability in a big city
