AT&T Starts Rolling Out DSS
AT&T has begun deploying Dynamic Spectrum Sharing (DSS), starting in north Texas. DSS is an optional feature of the 5G NR standard that allows 5G and 4G technology to share the same frequency band, allowing greater and more efficient deployment of 5G in existing frequency bands. DSS can dynamically re-assign radio spectrum in real time based on demand. So as more 5G-capable devices are active in a given area, more frequencies are automatically re-assigned from 4G to 5G. Without DSS, only relatively large chunks of radio spectrum are re-assigned from 4G to 5G, and not in real-time, based on demand. AT&T was among the first to present and champion this technology, eventually driving it into 5G standards. Verizon also plans to deploy DSS.

Verizon, AT&T, and T-Mobile have officially launched ZenKey, a new way quickly log in to apps that leverages the authentication that happens automatically every time your phone connects to the cellular network. Apps must be updated to support ZenKey, and developers have the option of enabling ZenKey as the primary login, or as the second token in two-factor logins, replacing PIN codes sent my text message, for example.
