So far gigabit-class speeds have not been seen. Now AT&T, is moving towards that goal. The provider will be the first US telecom to top 1Gbps on a mobile 5G network, achieving the feat in “multiple cities” using Netgear’s 5G hotspot. However, AT&T’s 5G is only available in certain areas in some cities, and now you need an invitation to buy the Netgear hotspot.
