To resolve the complexity in network capacities, we have evolved a simple framework to study capacity movements (growth, market shares) over time.
Network capacity = Number of base stations x Spectrum holding x Technology factor
Base stations: The listed players report number of base stations across technologies ? at an aggregate national level.
Spectrum holding: Taking the circle-wise spectrum data for various operators (from TRAI, DOT), we arrive at a single countrywide number (MHz) which is an average weighted by the circlewise revenues for the operator (industry revenues for Jio). Basically, this method of weighting has the effect of assuming that the total base station network of operators is distributed across circles in proportion of circle revenues. We ensure that spectrum gets counted only when operators have launched the relevant network in each circle
Technology: For a given amount of spectrum, the total capacity at a base station site is higher for 4G than 3G, while 2G has the least. With our technology factor we try to capture the relative efficiencies of various technologies in pushing through data in a given amount
of spectrum (i.e., the spectral efficiency). Discussions with industry experts, we believe 3G spectral efficiency should be anywhere from 1.5x to 3x of 2G (depending on which technology variants we choose) and in turn LTE should be anywhere from 2x to 9x
of 3G in spectral efficiency.
Based on the basis of above calculation here is breakup of distribution of Wireless Network Capacity,
Reliance Jio = 32%
Airtel India = 22%
Vodafone = 13%
BSNL = 11%
MTNL = 11%
Tata = 4%
Aircel = 3%
Reliance Communications = 4%
