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 its enforcement; 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 in the country as part of audit and assessment of the TSPs’ performance.
In view of complaints on call drops and other network quality issues, on behalf of TRAI, an Independent Drive Test (IDT) was conducted by
PhiMetrics Technologies Pvt. Ltd. From 8th January to 11th January 2019 covering various locations in Agra City & surrounding region.
The performance of Airtel, BSNL, Idea, Tata, Vodafone and Jio were monitored across various technologies (2G, 3G, and 4G). 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.
The test results obtained from these drive tests were utilized to assess the network quality for Voice and Data services in terms of
Voice: Coverage, Quality, Handover Success Rate, Call Setup Success Rate, Drop Call Rate and Block Call Rate.
Data: Download and Upload Throughputs, Web Browsing Delay, Video Streaming Delay and Latency
Drive Test Details For Agra:
Independent Drive test was conducted for a period of 4 days from 8th January to 11th January 2019 in Agra city & surrounding areas from
9:00 AM to 9:00 PM. Calls were made for 90 sec duration with wait time of 10 sec between calls in all technologies.
Voice Tests: The drive test covered a drive route of approximately 447 KMs over a period of 3 days from 8th January to 10th January 2019 .
Approximately 788 calls were made for each of the 12 networks: five 2G (Lock Mode) networks, five 3G (Free mode) networks and two
VoLTE network covering 6 unique TSPs.* In case of multiple call failure in similar geo location in given period of 60secs has been counted as one call failure
Data Tests: Data Tests were performed at 6 static locations for 1 days on 11th January 2019 ; five 2G (Lock mode) networks, five 3G (Dual
mode) networks and Four 4G (Free mode) networks covering 6 unique TSPs were tested.* For Voice and Data KPI’s, 2G measurement is done with UE locked on 2G, 3G measurement is done with UE in Dual mode (2G & 3G) and 4G measurement is done with
UE in Free Mode.
* 3G KPI’s which are calculated from UE in Dual Mode (2G & 3G) includes samples and events of 2G.
* 4G KPI’s which are calculated from the UE in Free Mode included samples and events of 2G & 3G.

RF Coverage relates to the geographical footprint within the system that has sufficient RF signal strength to provide for a call/data session. The
Coverage rate of an TSP is calculated on the basis of % of samples in which the Rx level ≥ -85 dBm, RSCP is ≥ -90 dBm & RSRP ≥ -110dBm.
The details are as follows.

Rx Quality Distribution
RxQual ≤5, EcNo ≥-14 dBm, FER≤ 4%, SINR >0 RxQual >5, EcNo <-14 dBm, FER > 4%, SINR ≤0
For measuring voice quality, as per the QoS norms, RxQual <=5 for GSM TSPs, EcNo >= -14 dBm for 3G TSP sand SINR >0 in case of VoLTE is
considered to be good, where as quality beyond this benchmark is considered to be bad. The benchmark should usually be ≥ 95%.
