A Wireless Extended Coverage Scheme for Electric Power Communication Network

With rapid construction and development of the distribution network, the hybrid network, composed of optical fiber and wireless private network, has become the major communication method for medium and low-voltage power distribution electric power business. In order to reduce the blind spot and extend coverage of current electric power communication networks, this article designs wireless communication network scheme and data acquisition equipment for power communication networks, based on low power wide area network technology. The scheme can realize the many kinds of equipment accessing to electric power communication networks, and satisfy the access control demands of electric power system. The communication capability experiments show that the wireless scheme has the advantages of long transmission distance, strong signal penetration and high scalability.
