AT&T has previously discussed its plans to use Dynamic Spectrum Sharing to add 5G network coverage by using software to dynamically share the same spectrum between 4G and 5G transmissions, side-stepping the massive exercise of re-farming spectrum. And today, according to a blog from AT&T’s Igal Elbaz, DSS “is live in portions of our network.”
To date, AT&T has been deploying 5G using both millimeter wave and low-band spectrum with the former branded as 5G+. The millimeter wave service is available in more than 30 markets and the 850 MHz flavor of 5G is available in nearly 200 markets.
