Airtel launches 4G in India on this april in Collabaration with LTE. It seems to be quite funny that most of the part in India has not been recieving 3G network still 4G launched in India but this network will give an unbelievable downloading speed about 40 MBPS and uploading speed upto  MBPS. And most of you would be thinking thatif it hives this high speed is it affordable? my answer would be yes it is affordable because rates are quite cheap in comparision to this service. This service is available in Kolkata and  will reach in other parts of India very soon.
