Utility Communications Wireless Solutions for Distribution Networks

Wireless networks can be implemented as an investment or fee based solution Utilities are investing in distribution automation (e.g. SCADA/DMS, RTU, communications) driven by the growing demand for electrical power and guided by cost saving potential and liberalization of the electricity market. Distribution automation allows remote monitoring and control of distribution substations and is based on a robust communication infrastructure. In these networks wired media (e.g. optical fibers) are often not available. Wireless solutions are therefore being used to enable communication with grid substations....

Fee based solutions Fee based solutions use existing communication networks. Capital investment is limited to the cost of remote radio terminals. They allow fast implementation and are of limited technical complexity. These solutions can be based on cellular networks, satellite or third party Point to Multipoint radio systems. The utility has to be aware of the limited control over the network which results in lower availability. This is often not acceptable for operational applications. Cellular based network An existing cellular network, GSM (with its technical improvements GPRS or EDGE) and...
