This review starts by providing a horizontal overview of Ubiquitous power Internet of Things(UPIoT). In particular, the review highlights the importance of the communication technology for power transmission and distribution system. Wireless access technology is a key technology at UPIoT network layer. By introducing low power wide area network(LPWAN) technologies combined with traditional wireless communication technologies, UPIoT are able to achieve exquisite energy management by reliable communications and extensive connections. In this review, the wireless access technologies applicable to UPIoT are divided into two categories: long-range wireless communication technology, which is suitable for communication scenarios of power equipment such as mass “transmit-transmit-transform-deploy-use” terminals, “factory-station-line-transform-house” distributed sensing terminals and short-range wireless communication technology, which is suitable for short-distance intelligent interactive terminal communication services. Finally, novel communication technologies and the application of 5G in power transmission and distribution scenarios are also discussed.
