–  Sub $50 smartphones: CEOs of telecom operators like Bharti Airtel, VimpelCom and Telefónica Latin America have lamented on the lack of cheap smartphones and asked for hardware manufacturers to create sub-$50 smartphones in emerging markets. Bharti Airtel MD, Sunil Mittal claimed that the smartphone penetration in India is only 5%.

– Content needs to be paid for: They also said that operators may have spoiled consumers by giving mobile content away too fast, thus making them “bad gatekeepers” when services don’t meet expectations. “The fact is that nobody really sees it from the other way – that YouTube is consuming massive amounts of bandwidth on the network. And somebody has got to pay for that. If Google, Facebook and others are not going to pay for it, it will be transferred entirely onto customers,” Mittal said.

Samsung: Samsung announced its intentions to be among the top three LTE network vendors by 2013 and among the top three players in the entire mobile infrastructure market by 2015.
