Service revenues from LTE subscriber acquisitions will hit US$530.5 billion by 2018, a huge jump from US$73.8 billion in 2013, according to ABI Research.

The analyst firm made the prediction after observing LTE commitments and support from the handset vendors. ABI Research also said that 2013 could prove to be a year that delivers a strong adoption profile for LTE carriers, with anticipated 183 million subscriptions by the end of 2013.

LTE coverage is set to cover huge areas in five years' time, said ABI Research analysts. "By 2018, LTE deployments should deliver population coverage of 57 percent (4.2 billion) and 31 percent (2.3 billion) in legacy WCDMA and CDMA2000 markets respectively. Significantly, LTE-TDD coverage should achieve 49 percent population coverage by the end of the five year period," said Jake Saunders, VP -- core forecasting, ABI Research.

Among the LTE operators, Korea's SK Telecom will be the first to launch commercial LTE-Advanced service. The LTE-Advanced roadmap will introduce a series of innovations that not only offer potential data download speeds that of 1 Gbps, but also advanced video streaming services such as eMBMS (Evolved Multimedia Broadcast Multicast Service) that offers a cheaper method of content delivery for providers.
