New Delhi, Sep 6 : As 4G penetration increases in India, Kolkata has emerged as the top city with a 4G availability score of an impressive over 90 per cent, London-based wireless coverage mapping company OpenSignal said on Thursday.
Kolkata topped the list of 22 telecom circles in the country.
However, the other 21 circles saw 4G (LTE) reach scores over 80 per cent, including top circles like Punjab with 89.8 per cent, Bihar on 89.2 per cent, Madhya Pradesh with 89.1 per cent, and Orissa on 89 per cent.
According to OpenSignal's latest 4G availability metrics, the results reflect the outstanding availability growth in India -- quite remarkable for a country which has only had 4G since 2012.
"We analysed our data for 4G availability across all of India's 22 telecoms circles in the 90 days from the start of May 2018, and found Kolkata came top with a hugely impressive score of 90.7 per cent," OpenSignal said in a statement.
Many of the top telecoms circles for 4G availability were in the East and North of the country, reflecting a similar trend in OpenSignal's analysis of LTE reach in India's cities six months ago.
In its April survey, Patna had beaten Bengaluru, Delhi and Mumbai to top the 4G availability metric that measures where users get access to an LTE connection most of the time.
Mumbai had ranked 15th while Delhi grabbed the 17th spot in 4G availability in India's 20 largest cities.
This time, Delhi was 12th while Mumbai 13th on the 4G availability list.
"The Indian government has just kicked off the process for a major spectrum auction in the country, which should allow the operators to make further improvements in these highly impressive 4G availability scores," said OpenSignal.
Reliance Jio has played a key role in increasing 4G penetration in India, helping the rural population get 83 million 4G subscriptions out of the total 238 million 4G subscribers by December 2017, said market research firm CyberMedia Research (CMR).
According to the CMR, 35 per cent of the 4G subscribers in India will use a 4G-enabled feature phone by 2020, taking the total 4G subscribers to 432 million.
