LTE 230MHz Wireless Private Network-Based Edge-Cloud Collaboration Architecture for Ubiquitous Power Internet of Things

LTE 230MHz wireless private network designed to provide services of long-range data transfer for power system, plays an important role especially in ubiquitous power Internet of Things (IoT). In recent years, there has been a highlight in interest in LTE (Long Term Evolution) technologies based on their advantages to meet the requirements of high speed, low communication latency and better coverage. Nevertheless, how to make full of these advantages for power applications has considerable challenges, such as the reliable operation of power system, the adequacy and security issues and cost-performance-reliability trade-off. This paper first synthesizes the evolution of LTE 230MHz, and describes current approaches, benefits, and barriers to its application for pratical life, while identifying their merits and weaknesses. It then discusses two of typical case studies applied in ubiquitous power IoT with regard to its issues, and if the community of ubiquitous power IoT is to be successful in doing so, alerts researchers to opportunities for conducting advanced research in reducing the rising tide of time consumption and cost, particularly in edge devices that are the target of ubiquitous power IoT which will determine the level of energy internet. We propose a solution to implementation of ubiquitous power IoT through the typical application scenarios, and discuss how to construct an edge-cloud collaboration architecture that can gain lower latency, less energy consumption, better reliability and maximum efficiency in operations. Through the architecture can make an accurate and convenient prediction and analysis combined with the architecture when applied to the area of ubiquitous power IoT for energy internet.
