Telecom equipment vendor VNL has come up with GSM or "Global System for Mobile" equipment that can be powered by solar. The motivation was difficulty in getting base stations in rural areas where little or no electricity exists as well as few skilled workers to install and operate the systems.
Their new "WorldGSM" systems include base stations that only need 50W and 120W of power to operate (compared to 3000 W for a typical GSM base station). The new base stations are completely solar powered and they include 72 hour back-up batteries also powered by solar.
Because they are now able to power this technology up with solar the mobile operators will be able to cut their operating expenses to a large degree. As well as having a positive effect on each area's environment.
