TRAI Releases Mobile Network Drive Test Findings for Sonitpur

The correct answer is Reliance Jio, whose average download speed on the tested routes was 221.18 Mbps, the highest of the four operators. Option A, Airtel, came second at 116.11 Mbps, roughly half of that figure, though Airtel did lead on uploads with 21.09 Mbps against Reliance Jio’s 15.98 Mbps. Option D, Vodafone Idea, averaged 20.04 Mbps on downloads and 6.69 Mbps on uploads. Option B, BSNL, was last at 11.72 Mbps for downloads and 4.32 Mbps for uploads, and it also showed the weakest voice performance, dropping 301 of 476 established calls. The lesson for the examination is to separate the download leader from the upload leader, because the drive test put two different operators at the top of those two columns.

The correct answer is the Telecom Regulatory Authority of India, the sector regulator, which conducts Independent Drive Tests through an appointed agency and publishes the findings for the information of telecom consumers. The purpose is to verify in real time the quality of voice and data services supplied by the telecom service providers, and to push those providers to improve. Option B, the Bureau of Indian Standards, is the national standards body and does not test mobile networks. Option C, the Department of Posts, runs postal services. Option D, the Centre for Development of Telematics, is a telecom research and development organisation that designs technology rather than auditing operators. Under TRAI the tests cover coverage, call setup success, dropped calls, call silence, speech quality and data throughput on live networks.

The correct answer is Assam. The drive test was carried out across parts of Sonitpur district, which falls in the Assam Licensed Service Area, and it was supervised by the TRAI Regional Office at Kolkata. Licensed Service Areas are the units into which telecom licensing is organised in India, and they usually follow state boundaries, which is why the report refers to the Assam LSA throughout. Options A, C and D name Meghalaya, Tripura and Manipur, which are other north-eastern states with their own service areas and were not part of this exercise. Remember the pairing of the district with its state and with the supervising regional office, since drive test questions are usually set on the place, the period and the operator that came out on top.
