• One hundred and eighty operators in forty-five countries/
territories are investing in mmWave (in the form of tests/trials,
acquisition of licences, planning deployments or engaging in
deployments).
• One hundred and thirty-two operators in 22 countries/territories
have been assigned mmWave spectrum (often on a regional
basis) enabling operation of 5G networks.
• Twenty-eight operators in 16 countries/territories are known to
be already deploying 5G networks using mmWave spectrum.
• Nineteen countries/territories have announced formal (datespecified)
plans for assigning frequencies above 24 GHz between
now and end-2022.
• One hundred and twelve announced 5G devices explicitly
support one or more of the 5G spectrum bands above 24 GHz
(though note that details of spectrum support are patchy for precommercial
devices). Seventy of those devices are understood to
be commercially available.
