The Ericsson Mobility Report released today says mobile subscriptions through 2013 are now 6.7 billion, although the actual number of subscribers is around 4.5 billion, since many have several subscriptions.
LTE subscriptions reached 200 million in Q4 2013. Some 40 million new LTE subscriptions were added during Q4 2013. Close to 60% of all mobile phones sold in Q4 2013 were smartphones, compared to around 45 percent in Q4 2012.
The report also shows that data traffic grew 70% between Q4 2012 and Q4 2013. Voice traffic, meanwhile, was practically flat, and an increasingly tiny percentage of the bandwidth used.
A recent GSMA report suggests that China will be a significant player in the field of 4G with up to 900 million 4G users by 2020.
4G Americas predicts that by the end of 2018, some 1.3 Billion connected devices would use LTE while HSPA/HSPA+ subs would number 4.2 billion.
