BhartiCEO of world #3 Bharti, says, "You build one massive network from which everyone is served." Billionaire Sunil Bharti Mittal has 340M million customers across Asia and Africa. "The current system of building networks for each operator needs to be completely dismantled," he tells Economic Times. "Far too much wastage is happening. Netcos and mobile companies should separate themselves. Spectrum should be pooled in a netco. Your spectrum efficiency rises significantly. The need for base stations is halved immediately. The time for a license and 500,000 base stations creating a value is over."

With wireless no longer growing explosively, most countries can't afford to build so many networks. “The density of expenses in terms of capex, spectrum is going up, whereas revenue is tapering off." Vodafone's Vittorio Colao and Stéphane Richard of France Telecom/Orange both are demanding the EU get rid of some competitors - preferably all of them. Colao thinks all but one or two mobile companies can't survive. Every executive at U.S. telcos believes either Sprint or T-Mobile need to disappear. 

One network is much cheaper than two; two cheaper than the four to seven usually needed for strong competition.
