AT&T today shared an update on the expansion of its 5G network, and shared plans for its 5G network going forward. The company's sub-6 GHz 5G network now covers 250 million people nationwide. AT&T "5G+" — its brand for mmWave 5G — now covers parts of 38 cities and 20 venues (stadiums and arenas). The company plans to expand that mmWave network to 40 cities + 40 venues by the end of this year. mmWave offers much faster data speeds than sub-6 GHz 5G, but with very limited coverage. Finally, the company plans to start deploying C-Band 5G before the end of this year, expanding to cover 70–75 million people by the end of 2022, and 200 million by the end of 2023. C-Band is a new frequency band recently auctioned off by the FCC that allows a better balance of data speeds and coverage compared to existing bands. AT&T purchased licenses for 80 MHz of this spectrum, and will start deploying the first 40 MHz this year.
