Et donc que dit ton lien très clair sur la 5G NSA ?
5G NSA phase: It is foreseeable that most operators will start by launching 5G services in NSA mode. Before launching 5G services, these operators will provide voice services for 4G subscribers through CSFB or VoLTE, while still maintaining voice services for 2G or 3G subscribers through the CS network. When 5G services are launched, operators should, by default, enable VoLTE services for 5G NSA subscribers. Otherwise, users will need to fall back to the 3G network when making and answering calls. This fallback would decrease the bandwidth from 5G to 3G speeds (up to a 100x decrease), and it would also mean an increased time to establish a call. In this case, users wouldn't really be able to fully experience the outstanding experience that can be provided by 5G, and instead would see a degraded version. This would be despite their willingness to pay for better 5G, and despite them switching to a 5G capable terminal and mobile plan.
Xavier Niel ignorait-il ceci ?
Le papier date de mars 2019, il sera plus difficile cette fois ci de tenter de jouer sur la date.
