The Global Mobile Suppliers Association (GSA) has provided a snapshot of 5G spectrum activity around the world as of the end of December 2017. “Activity” can include plans, trials, and regulatory consideration. The bands range from 600 MHz to 86 GHz. There’s some inaccuracy as GSA depends on incomplete information from some regulators, operators, and vendors, but it’s the best collection of public domain information.
