The findings of the IDT have already been intimated to all the TSPs concerned. Key parameters assessed: a) Voice services: call setup success rate (CSSR), drop call rate (DCR), call setup time, call silence rate, speech quality (MOS), Coverage. b) Data services: Download/upload throughput, latency, jitter, packet drop rate, and video streaming delay.
As per TRAI, Bharti Airtel (Airtel), Bharat Sanchar Nigam Limited (BSNL), Reliance Jio (Jio) and Vodafone Idea Limited (Vi) had call setup success rate of 96.34 per cent, 73.63 per cent, 99.12 per cent and 80.20 per cent respectively while a call setup time of 2.53, 2.81, 0.97 and 2.08 seconds respectively in auto- selection mode (5G/4G/3G/2G).
