With a developing economy, China prioritizes low carbon emission and clean energy; smart grids are an important part of China's policy to develop and use energy in a way that is responsible, secure, and reliable. Accordingly, China Southern Power Grid, which provides electricity to 230 million people, piloted a smart grid empowered by wireless broadband.
Huawei was called on to build a wireless broadband smart grid solution, which enabled China Southern Power Grid to deploy the world's first wireless distribution communication network at a frequency of 1.8GHz. As the first 4G TD-LTE enabled smart distribution network, it features automatic distribution and measurement, as well as video surveillance of the distribution network etc. This makes the grid smarter. Furthermore, it can provide China Southern Power Grid with higher wireless bandwidth for distribution automation data collection, control and video surveillance, as well as emergency communication, distribution network online monitoring, BYOD and other value-added services.
The smart grid can not only save energy and reduce emissions, but also increases power supply reliability, and lays the foundation for smart homes. The success of the smart grid proves the feasibility and superiority of eLTE in power distribution automation.
