ABI Research estimates that there will be nearly 1.37 billion 4G LTE subscribers worldwide by year-end 2015, up from nearly 650 million in 2014.
ABI Research forecasts that the LTE subscriber base will exceed 3.5 billion by 2020, demonstrating a 5 year CAGR of 20.8%.
The exponential rise in LTE points-of-presence covered justifies the need for sustained investment in LTE infrastructure, which is expected to grow nearly 10% year-on-year.
Major carriers in the United States are still investing heavily in LTE technology to consolidate their networks. Verizon Wireless is partnering with Ericsson to deploy small cells or micro-basestations to densify its network capabilities, with nearly US$500 million allocated for small cells deployment.
