Trai has been conducting drive by tests in various telecom circles around the country, to transparently report quality of call information by various operators across different technologies. A specific point of interest is to measure if telecom service providers meet the call drop rate benchmark, which has been a bone of contention between Trai and TSPs. Most operators met the call drop benchmarks in Kanpur, Lucknow and Ahmedabad. However, most operators did not pass the test in Mumbai. Here is how the operators performed in Ranchi, as well as Darjeeling and Sikkim.

Ranchi
In Ranchi, the drive tests were conducted over 320 kilometers. Except for Telenor 2G, all the operators failed the call drop test. Most operators passed the call setup success test in Ranchi. Aircel 2G, Telenor 2G, Airtel and BSNL did not meet the call setup success benchmark. Only MTS CDMA failed the blocked call rate benchmark. Only Airtel 3G and BSNL 3G passed the call quality test, all other operators failed. The entire table of results are below.

Darjeeling and Sikkim
The drive tests were conducted over 302 kilometers in Darjeeling and Sikkim. The most important finding here is that all operators, without exception, failed to meet the call drop rate benchmark of less than 2 percent. Only Aircel 2G/3G, MTS CDMA and Vodafone 3G passed the call setup success rate benchmark. MTS CDMA was the only operator to pass the blocked call rate test. Except for Vodafone 3G and BSNL 3G, all operators did not meet the requirements for call quality. The results are tabulated below.
