The research says that solar-powered mobile phone base stations will turn mobile communications into the greenest high industry.
According to an estimate, more than 335,000 base stations all around the world will be using sun power by the end of 2013 and around 40,000 among them would be completely autonomous and off-grid.
Most of these base stations will either use mains electricity or diesel to boost their solar panels and particularly in those Northern countries where it is needed because of population density and cloud cover.
In this connection, the developing countries of the world may become the biggest winners as remote communities will receive phone coverage and internet connections for the first time. Some UN figures suggest that half of the world is still not able to make a phone call.
Some other technologies that networks may consider improving coverage are wind power, compressed air and fuel cells.
