(Telecompaper) Verizon announced a major expansion of its mmWave 5G network in the US, coinciding with the release of the first iPhones to support the spectrum. The service is available in 19 additional US cities, 19 stadiums and six airports, with peak speeds of up to 4 Gbps in some places. Verizon is also turning on nationwide 5G service thanks to dynamic spectrum sharing with its other frequencies, with availability for more than 200 million people.
