The TRAI has criticised the telecom companies for the continued call drops since it is mainly due to the lack of infrastructure like towers. The telecom companies are providing connections much more than their capacity to serve. While there has been increase of 12% in GSM calls and 106% in data usage, the number of base stations have gone up only by 8%. The telecom operators have been asked to provide the details of the infrastructure, number of towers etc. by the TRAI.
