This shouldn’t be surprising, right? In an analysis done by TRAI, Airtel has emerged as the most congested GSM network for the period of Oct-Dec. During this period, Airtel had 14 POIs (Point of Intersection) with congestion followed by Vodafone who had 12 and Reliance Communications and Idea with 11 each.
Note: POI signifies the ease with which a customer of one network is able to communicate with a customer of another network. This parameter also reflects as to how effective is the interconnection between two networks. TRAI has set a benchmark of less than 0.5 percent, which means out of 200 calls between two operators, there should be a single call facing a congestion problem.
