TRAI is conducting tests to check call drops, voice quality on Airtel, Vodafone, Idea, Jio networks

Indian telecom regulator, TRAI, has begun operator-assisted drive tests to check call drops and voice quality of mobile services.

The operator-assisted drive test will assess the real-time data to monitor the level of call drops and voice quality across multiple cities.

The operator-assisted tests have already taken place in Mathura (UP-West circle), Jaisalmer, (Rajasthan), Ujjain (Madhya Pradesh) and Mangalore (Karnataka) among others.

"The operator-assisted drive tests have started in all the five regions of TRAI, and a number of cities have been covered," its Chairman RS Sharma told PTI.

The tests are different from independent drive tests conducted by the regulator as it also involves telecom firms' equipment and costs.

Typically, drive tests -- whether TRAI's independent tests or operator-assisted tests -- assess the performance of networks on various quality benchmarks, including call set-up success rate, call drop, blocked calls and Radio Frequency (RF) coverage.
