Huawei has partnered with telecoms tower operator China Tower to conduct a joint innovation test on 5G energy solutions
According to the telecoms equipment provider, the test showed that by using technologies such as intelligent peak shaving, intelligent voltage boosting and intelligent energy storage, it is possible to achieve site deployment without changing the mains, power distribution and cabinets in the evolution to 5G.
With network capacity set to increase rapidly when 5G connectivity is rolled out, the power consumption required for a single 5G site is much higher than a 4G site. In addition, a large number of end sites will be deployed, causing the power consumption of the entire network to increase exponentially, Huawei said.
China Tower and Huawei agreed to work together last year, and set up a joint working team to lower investment, reduce OPEX, and achieve intelligent operation & management (O&M).
Huawei’s 5G Power Solution is designed to intelligently control batteries and air conditioners based on a site’s power consumption and mains capacity to achieve “no mains change”, reducing the capital investment when sites evolve to 5G.
The company gave the example of Hefeng Village, where the average load is 1.4 kW, the peak load is 2.7 kW and the AC power limit is 1.6 kW. When 5G services are simulated, the peak load exceeds the power limit and lithium batteries start to power the load to achieve intelligent peak shaving. When the load is light, lithium batteries immediately switch to equalised charging mode.
The team also tested various intelligent features such as intelligent solar access, hybrid use of lead-acid and lithium batteries (battery pooling), and mixed use of old and new power supplies (power pooling) to verify the on-demand battery and power supply configuration and modular evolution.
5G technology will launch in the UK this year. To read about how businesses are preparing for the arrival of next-generation internet connectivity, download our Next-generation connectivity report today!
