At launch, the service 5G AT & T could only make use of the lone carrier 100MHz to connect, speed limits, which were often not much better (or potentially worse) than LTE. The new approach is aggregated four of these carriers, giving it that much more headroom even in the real world. He should get faster, more later in the year, when AT & T combines LTE and 5G in one compound.
The problem, as with almost any carrier 5G (including Engadget parent company Verizon), is currently in a position to take advantage of this rate. AT & T in the 5G only available in some areas in several cities, and you'll need an invitation to purchase a Netgear access point. Even then, Wi-Fi router is not fast enough to ensure that the peak rate. You'll have to wait and 5G WiFi smartphones 6-equipped access points before the technology can live up to the potential. This clearly illustrates the 5G work – it just will be a long time before we can expect to achieve this performance is ideal conditions.
