Customer Requirements

Smart power grids are built on an integrated and high-speed two-way communications network. They involve the electricity production, transmission, distribution and consumption processes and consist of the power generation, transmission, conversion, distribution and consumption equipment as well as auxiliary systems. Smart power grids represent a high integration of the electricity flow, information flow and service flow. Wireless communications are the best choice for quickly building a dedicated electric power communications network, thanks to advanced features, such as flexible networking, rapid deployment, easy addition of new service points and mobile service. The requirements for wireless communications include:
