Optimal Scheduling of 5G Base Station Energy Storage
This article aims to reduce the electricity cost of 5G base stations, and optimizes the energy storage of 5G base stations connected to wind turbines and photov
But the analyst firm says a typical 5G base station consumes up to twice or more the power of a 4G base station; it notes that the industry consensus is that 5G will double to triple energy consumption for mobile operators, once networks scale.
Model of Base Station Power System The key equipment in 5G base stations are the baseband unit (BBU) and active antenna unit (AAU), both of which are direct current loads. The power of AAU contributes to roughly 80% of the overall communication system power and is highly dependent on the communication volume .
Huawei data from FierceWireless suggest the typical 5G site has power needs of over 11.5kW, up nearly 70 percent from a base station deploying a mix of 2G, 3G, and 4G radios.
5G hardware is currently a small part of the overall traffic managed by operators, but as roll-out continues, it will soon become the main source of the mobile landscape's energy requirements. Not only will the hardware potentially require more energy, but there will be more sites, compounding the energy demand.
