In 2014, LTE subscribers will reach 303.1 million, compared to 33.4 million for WiMAX.

Driven by widespread mobile network operator (MNO) adoption, the next-generation wireless technology known as long-term evolution (LTE) by 2014 will have more than nine times as many subscribers as its main rival in the 4G market, Wireless interoperability for microwave access (WiMAX), said the research report.

LTE subscribers worldwide are expected to top 14.9 million in 2011, up from 6.8 million last year. In comparison, global subscribers in 2011 on LTE - championed by most tier-one MNOs globally, such as AT&T and Verizon Wireless in the US, as well as Vodafone and TeliaSonera in Europe - are projected to reach 10.4 million.

But while that total is smaller than WiMAX numbers, it reflects an astonishing leap from just 702,000 users in 2010 and virtually zero in 2009.

“With WiMAX enjoying a two- to three-year head start in next-generation network deployments, it presently enjoys a major advantage in market share in the 4G segment,” said Francis Sideco, principal analyst for wireless research at IHS. “However, with LTE supported by most of the leading wireless operators worldwide, it will rise to surpass WiMAX in 2012 and then dominate worldwide during the following years.”

Although the International Telecommunications Union has announced that neither LTE nor WiMAX are officially 4G technologies, industry vernacular has adopted the designation for both.

Regardless of how they are categorized, this set of next-generation mobile wireless standards is characterized by very high data-transmission speeds, flexible width channelization and perhaps, most importantly, low-latency packet transfers.

As is normal for the industry, while older wireless technologies such as 2G and 3G continue to be in use in every part of the world, the transition to higher-speed broadband networks is under way, and the race is on to determine which 4G technology will provide the expected performance and enhancements from day one.

An estimated 10 LTE operators worldwide have launched to date, and more than 30 new operators will start LTE services this year, IHS forecasts.

For WiMAX, the majority of operators can be found in Europe, followed by the Asia-Pacific region, the Middle East and Africa and then the Americas.
