Worldwide LTE-Advanced (LTE-A) subscriptions will post a compound annual growth rate (CAGR) of 295 percent between 2013 and 2018 to reach 500 million, according to ABI Research.
North America will be the most aggressive LTE-A market, followed by Asia-Pacific and Western Europe, said ABI Research analysts.
North America will commercially launch LTE-A by the end of 2013 and mobile subscriptions will approach 220 million by 2018, contributing 44 percent of the global LTE-A market.
In Asia Pacific, the LTE-A subscriptions will clock 159 million by 2018, while in Western Europe, the adoption rates should reach the figure of 55 million.
Confronted with an explosion in mobile data traffic and a need for greater bandwidth, Carrier Aggregation, an essential feature of LTE-A, can help operators to build greater transmission capacity, relieving stress on legacy spectrum assets.
"SK Telecom is aggregating two frequency bands in the 850 MHz and 1800 MHz bands to commercially launch its LTE-A services in September 2013. All the signs indicate it is on schedule to do so," said Marina Lu, research associate at ABI Research.
