The India appendix of the Ericsson Mobility Report, released today, shows key trends and forecasts on mobile traffic, subscriptions, consumer behaviour and technology uptake in the country.
GSM/EDGE subscriber base is expected to peak in 2015 and likely to decline thereafter as subscribers migrate to 3G services, the report said.
LTE subscriptions are likely to top 230 million, forming around 17 per cent of the total subscription base by 2020, it said.
The WCDMA/HSPA subscriptions are anticipated to grow from over 120 million in 2014 to around 620 million by 2020, and will account for 45 per cent of the total subscription base by that time, it added.
GSM/EDGE technology has the widest reach in India with 95 per cent population coverage while WCDMA/HSPA is expected to cover approximately 90 per cent by the end of 2020. Additionally, around 40 per cent of the population will be covered by LTE networks by 2020.
The number of smartphone subscriptions is expected to reach over 750 million by 2020, up from 130 million in 2014.
Video streaming accounts for the most used mobile data service among Indians, followed by social networking, the report noted.
