As the wireless telecom market went into consolidation for last 5-7 years, we can see only 4 operators in the market, i.e. Jio, Airtel, Vodafone Idea and BSNL (MTNL-BSNL merger is announced two days back).
Frankly speaking Jio is ahead of all, thanks to its backhaul assests which will also fuel its broadband dream as well as upcoming 5G venture in long run.
Jio's tower arm, as it was spun off from main company as Jio Infratel in March 2019, is announced to be acquired by Canada's Brookfield Infrastructure Partners L.P. and its affiliates in multiphases. With 45000 towers from Reliance Communications, and another 125000 towers made by Jio itself, the total number of Jio towers reaches 1,70,000; which mades Jio Infratel as largest tower company beating Indus Towers. However 25% of them are monopoles. (India's tower companies in detail )
