1. City-Level Performance
City-Level Details Operator Performance against Key Performance Indicators :
. • The observation shows that poor quality and poor mobility in 2G network is a clear indication of high Call drop
rate. • Another reasons for High drop is coverage holes which is common to all operators due to hilly terrain.
All 3G networks
• All 3G networks in drive area have limited coverage which allowed to maximum number of calls attempted on 2G networks which again results to drop call due to poor quality and poor Mobility on 2G networks.
MTS CDMA (CDR : 11.56%, BCR : 0.34%)
• Rx quality of MTS CDMA is poor and not meeting benchmark criteria of >=95%.
• Coverage holes in drive test area is another reasons for high call drop Rate.
• Poor signal quality is the clear indication of high call drop in network.
All operators failed to meet the Call Drop Rate Benchmark of <=2%
Key Highlights
• All operators failed to meet the Call Drop Rate benchmark of <=2% on 2G and 3G networks.
• All other operators fail to meet the benchmark by a wide margin. Other than Idea 2G, all operators have a Call Drop
rate of >10%. A high call drop rate, clearly indicate urgent need for improvement in order to deliver reasonable levels
of service

1. Methodology & Other Details
Overview:
Telecom Regulatory Authority of India has been entrusted with the task of laying down the standards of quality of service to be provided
by the service providers and ensuring that the quality of service is provided as per norms; and also TRAI is responsible for conducting
the periodical audit of such services provided by the service providers so as to protect the interest of the consumers of
telecommunications service
TRAI is regularly monitoring the performance of Telecom Service Providers (TSP) against the benchmarks for the various Quality of
Service (QoS) parameters laid down by the Authority. TSPs submit Performance Monitoring Reports to TRAI every quarter. TRAI also
undertakes audit and assessment of Quality of Service through independent agencies to verify the Quality of Service claimed. The Audit
agencies conduct sample ‘Drive tests’ across various cities all over the country as part of audit and assessment of the TSPs’
performance
In view of complaints on call drops and other network issues, on behalf of TRAI, an Independent Drive Test (IDT) was conducted from
25th May 2016 to 27h May 2016 covering various locations in Darjeeling, South Darjeeling, Gangtok. The performance of Aircel, Airtel,
BSNL, Idea, Vodafone, MTS was monitored across various technologies (2G, 3G and CDMA). The drive test route was defined on the
basis of several factors that include - areas from where call drop complaints are commonly received; areas of heavy usage; residential
areas away from arterial roads; office areas; areas where previous Drive tests showed network issues; etc.
For the purpose of these tests, 2G + 3G Mode (Auto) was used. The test results obtained from these drive tests were conducted to
assess the network condition more specifically in terms of Radio Frequency (RF) Coverage; Rx Quality; Call Setup Success Rate; Call
Drop Rate; Blocked Calls and Carrier to Interference ratio
Drive Route Details For Darjeeling Area:
Independent Drive test was conducted in Darjeeling area from 9:00 AM to 9:PM from 25th to 27th of May 2016. The total drive test
covered in Darjeeling area was approximately 302 km over a period of 3 days. Total of 3008 calls were made for five 2G networks,
four 3G networks and one CDMA networks covering Six operators. Roads and Areas covered in Darjeeling & Sikkim is shown in the
