Airtel has maintained its quality of service in broadband. Its highest speed in January was 8.42 mbps as per latest report by Telecom Regulatory Authority of India (TRAI), while, Reliance Jio’s speed has fallen drastically. Jio's speed reduced by more than half to 8.34 mbps from 18.14 mbps peak speed it registered in December.

The monthly average mobile data speed published by the Telecom Regulatory Authority of India showed that the download speed on Airtel network has almost doubled in January to 8.42 mbps from 4.68 mbps.

This is the third time when Airtel network has shown highest download speed since September.

Trai collects and computes speed of mobile data from subscribers across the country with the help of MySpeed application on real time basis.

A Credit Suisse report published in February said Airtel 4G offers the best download speeds in general at around 12Mbps based on its study conducted across over 30 cities.

“Jio, Vodafone and Idea are close to each other (7-8Mbps). We suspect Jio’s speeds are impacted by the high load on the network in the free offer period. Jio carries over 90 per cent of all data traffic in the country currently while we believe their network capacity share is closer to 35 per cent,” the report said.

Among other networks, download speed on Vodafone and Idea network also increased in January over previous month.

Average download speed on Vodafone increased to 6.8 mbps from 6.7 mbps and on Idea Network it increased to 6.62 mbps from 5 mbps.

Mobile broadband speed on state-run telecom firm BSNL declined to 3.16 mbps in January from 3.42 mbps in December.
