The number of LTE-Advanced networks in commercial service has reached 100 worldwide, up from 33 at the end of 2014, according to 4G Americas.
Figures published by the trade organisation late on Tuesday reveal that 49 countries boast at least one LTE-A network, while 34 have at least two up and running. By comparison, when it comes to ‘standard’ LTE, there are 430 live networks in 145 countries.
"We expect almost all operators to deploy LTE-Advanced which has a vigorous roadmap of technological innovation," said 4G Americas president Chris Pearson, in a statement.
Citing figures from Ovum, 4G Americas noted that the number of LTE subscribers now stands at 907 million worldwide, up from 635 million at the end of the first quarter. It predicts there will be 3.6 billion by 2020.
By 2020 LTE will account for 42% of all mobile connections, inching just ahead of HSPA with 41%.
Meanwhile, 4G Americas said it expects the next version of LTE-A, officially known as 3GPP Release 13 but dubbed LTE-Advanced Pro, will be an important stepping stone to 5G.
"5G development is the focus of much of the industry; however, LTE-Advanced will continue to evolve with creative new features to serve customers for many years before 5G networks are commercially deployed," said Vicki Livingston, head of communications at 4G Americas.
