With its download speed peaking at 25.6Mbps, Reliance Jio led the mobile broadband speed test for November 2017, according to the latest data published by Telecom Regulator Authority of India (Trai).
Airtel, which is third in the rankings, trailed Jio by a huge margin as download speed recorded by the operator was 9.8Mbps.
As per the data published by telecom regulator , Vodafone was at the top with download speed of 10Mbps followed by Bharti Airtel 9.8 Mbps and Idea Cellular 7 Mbps in November 2017.
A top speed of 21.8 Mbps was registered by Jio in October.
Trai collects and computes data download speed with the help of its 'MySpeed' application on a real-time basis.
In terms of upload speed, Vodafone overtook Idea Cellular in November with a speed of 6.9 mbps. Idea registered a peak upload speed of 6.6 Mbps, followed by Jio with a speed of 4.9 Mbps. Airtel hit an upload speed of 4 Mbps. Idea topped the chart in October registering the highest upload speed of 7.1 Mbps.
Meanwhile, the Telecom Disputes Settlement and Appellate Tribunal (TDSAT) has reportedly asked the TRAI to initiate action against Reliance Jio for failing to adhere to the seven-day limit of reporting ''the Welcome Offer'', which the telco introduced when it started commercial operations on 5 September 2016. The telco had offered free voice, data and messages for three months, under the plan.
The Economic Times reported that the order issued Thursday, could lead to a penalty of up to Rs2 lakh on Jio, which now counts more than 160 million 4G subscribers with an average revenue per user (ARPU) of over Rs150 highest among telcos in India.
