Google initially partner with BSNL for testing this technology by using broadband spectrum in 2.6 Ghz band. It replaces mobile towers and provides 4G services directly to 4G mobile phone. It can transmit signal for area about 40 km in diameter using LTE or 4G communication technology. Google uses solar panels and wind to power electronic equipment in balloon throughout the day. The location of the pilot is expected to be in Andhra Pradesh or Maharashtra.
