Environmental Strategy Energy Management System Given our energy consumption mainly occurred at numerous but scattered communication facilities such as base stations, we chose to take advantage of our existing system resources such as the Wireless Network Management System (WNMS) and the Power Environment Monitoring System to form a centralised Energy Management Platform, and use the Platform to intelligently gather power usage data, irregularities in power consumption, and power usage effectiveness (PUE) data of all facilities including base stations and equipment rooms.
