Global 5G status update from GSA – January 2019.
By mid-January 2019 GSA had identified 2010 operators, in 83 countries, investing in 5G mobile and 5G FWA networks, in the form of tests, trials, planned and pilot deployments, and launches. (The numbers at the end of April 2018 were 154 operators in 66 countries.)
Operators have announced 524 separate demonstrations, tests or trials that we have been able to identify (by end-November 2018)
At least 87 projects have involved testing Massive MIMO in the context of 5G (i.e., MIMO trials involving 64 or more transmitters, or lower order MIMO used on new high frequency spectrum bands, or involving some other 5G aspect such as New Radio characteristics).
At least 26 projects explicitly featuring network slicing.
