Informa Telecoms & Media senior analyst Kristin Paulin said the rapid adoption of LTE, with worldwide connections more than doubling year-over-year to 1Q 2014, has been driven by smartphones.
"It takes an efficient network like LTE to handle the increase in mobile data traffic from smartphones," Paulin said.

LTE subscriber numbers grew 50% in Latin American countries, from two million to thee million in the first quarter with the expansion of LTE networks and availability of LTE devices.
4G Americas president Chris Pearson said Latin America realised tremendous growth of LTE in the first quarter of this year.
"Brazil is leading the acquisition of LTE connections in the region, speared by the World Cup and Olympic events that have progressed the deployment of LTE network coverage," Pearson said.
"The demand for mobile broadband services across the region continues to positively affect the increase in LTE subscriptions."
