A new IHS iSuppli Wireless Communications Special Report predicts that the global LTE subscriber total should surpass 100 million users sometime this year. According to the firm, that number is then expected to skyrocket to 198.1 million in 2013, which would be a 115 percent jump from the 92.3 million subscribers seen last year. The lion's share of that growth is courtesy of Verizon here in the States, with AT&T steadily gaining ground. Both Sprint and T-Mobile should significantly add to that total this year with LTE builds of their own.
