If every object had a label indicating the greenhouse gases it emitted, the label on your mobile phone would be much larger than that of your fixed-line phone.
This week China Mobile has received the first batch of the smallest and most energy-efficient GSM base station on the market. According to the industry, in a large metropolitan city with 5,000 base stations, the technology can reduce as much as 73,000 tons of CO2 emissions per year, equivalent to the amount emitted by 21,000 cars – the plan is to save up to 70% of mobile networks’ energy consumption.
The solution includes minimizing the number of base station sites by using software features to increase coverage, as well as minimizing the need for air conditioning to cool the sites. Utilizing software features to optimize the use of radio access for wireless communications is another element of the solution (as night base-station traffic is much lower than peak daytime hours, part of the base station can be closed or set on power save mode).
China Mobile is to collaborate with 15 equipment vendors to deliver on its “Green Act” which in the end aims to establish an electronic supply chain management system that improves energy efficiency in the provision of mobile services.
P.S.: Ericsson base stations have been awarded a prize from the Chinese government for a 30% reduction in carbon dioxide emissions associated with construction and a 40% reduction in energy consumption.
