It is not a question of if LTE will be the dominant 4G mobile technology, the question is when LTE networks will proliferate, according to a new report from Visant Strategies. In many cases wireless mobile operators across the globe will implement HSPA+ before transitioning fully to LTE the second half of this decade.
"HSPA+ is expected to be the dominant form of mobile broadband internet for the next five to ten years especially since LTE-oriented spectrum is being slowly released throughout the world," said Andy Fuertes of Visant Strategies. "Carriers will need to deploy LTE to remain competitive in many cases, but today HSPA+ is an attractive choice to solve the smart phone capacity crunch many operators face due to its relatively cheaper investment."
According to "3.5G and 4G 2010: The Move to Worldwide Mobile Broadband," LTE deployments will gain momentum in 2014, although some major carriers will have deployed the consensus 4G winner by then.
"By 2015 the 3.5G/4G subscriber distribution will consist of HSPA+ with over half of all 3.5G and 4G subs, LTE with about one-third and mobile WiMAX accounting for close to one-tenth of all 3.5G and 4G subs worldwide," said Larry Swasey of Visant Strategies. "Backhaul in all of the advanced wireless networks needs to be beefed up as well in order to take real advantage of 3.5G and 4G."
WiMAX remains strong as a 3.5 GHz fixed/portable platform but a lack of support from major carriers is resulting in a minimal role in the mobile wireless market, the report finds. HSPA+ and LTE may be used in traditional 3.5 GHz bands over the long term.
