Ericsson has been active for a number of years in creating renewable energy solutions for radio base stations, especially in remote areas. The first solar charged site was installed in 2000 and there are over 200 sites today. Ericsson’s most recent development is the solar powered main-remote radio base station, RBS 2111, recently deployed in Sumatra, Indonesia (in partnership with Telkomsel).

The main remote radio base station uses up to 60 percent less energy than a traditional radio base station and is ideal for rural areas with limited electricity supply.

The Village solar charger
With Sony Ericsson, Ericsson has developed a mobile-phone solar charger for the Millennium villages project. This innovation, intended for use in villages almost anywhere in the world, is capable of recharging at least 30 mobile-phone batteries per day and eight phones simultaneously.

India
In 2007, Ericsson worked with local operator Idea Cellular and the GSM Association’s Development Fund to launch 23 radio base stations powered by biofuels, extending the network in rural India. The bio-diesel is produced locally, with used cooking oil from restaurants. The 23 commercial site locations are in areas that have not previously had access  to a mobile network due, in large part, to an unreliable power supply.
