Joint study on renewable energy application in base transceiver stations

Vodafone, China Mobile and Huawei have started a joint green technology programme to advance renewable energy application in wireless networks to reduce diesel consumption and to contribute substantially to CO₂ emission reduction. Three experimental BTS sites, an NFB PV site, a macro BTS PV-diesel site and a distributed BTS PV-wind site, were set up to verify and optimize system design and implementation. By computation and real operation, the power reliabilities of the three sites are 100% with fewer costs in terms of 3-year TCO in comparison to dual D.G. systems respectively. The CO₂ emission can be reduced greatly.
