AT & T's first 5G speed tester is here and they are not good



While 5G has great potential, the only major effect it has achieved so far in the United States is confusing the public. This is largely due to poor advice on market strategies and questionable 5G "launches" of the four major wireless operators. In the latest addition to this frustrating saga, we finally see speed tests on the AT&T fledgling 5G network, and the results are far from impressive.

The results were posted on Reddit and reported by PCMag PCMag sascha victory Redditoren, mwb6d, posted a screen showing a 194.88 Mbps download speed, 17.08 Mbps upload speed and 77 ms latency . It's not a bad result in itself, but it's also about the same as the gigabit LTE speeds we've seen these days. In fact, when the redditor uploaded a 4G test from the same site, it returned with a very similar result: 1

87.44Mbps download speed, 8.14 Mbps upload speed and 77ms latency. How can this be?

Well, that's an explanation, though not quite satisfactory. AT & Ts 5G networks (now only accessible via a Netgear Nighthawk 5G hotspot) are in their infancy and while it is slightly more efficient than LTE when used in the same channels and with the same channel sizes as LTE, there are top speeds. is largely dependent on broad spectrum channels, especially millimeter wave spectrum. Finally, operators will distribute more, but currently AT & T uses 100MHz millimeter wave spectrum with 2×2 MIMO antennas, giving a maximum of 625 Mbps speeds on pure 5G (although the carrier has also thrown out a 979 Mbps number for its top 5G speed) . Both of these speeds are lower than LTE's peak, which is 1.2 Gbps under ideal conditions. So the explanation is finally – AT & Ts 5G is just not fully developed yet.

But that's promise. As mentioned above, the 5G's real strengths are to give a larger spectrum of frequencies more often than LTE. As PCMag s Segan points out in December explains, has a great potential for AT & Ts 5G and all 5G to offer higher floor than LTE – speeds cannot be shockingly high, but hopefully they will prove much more consistently high results. Take a look at Segan's piece for a more thorough explanation.

Nevertheless, the 5G hype machine has promised much more than marginally better performance, higher floors, and slightly lower latencies, so it is reasonable to be slightly disturbed by these early results, which are worth pointing out, are the only reports We have seen so far, due to AT & Ts's refusal to issue auditing units. In addition, it is the entire 5G E-mess.

As anyone might have expected, operators are so busy beating each other to 5G milestones, constantly becoming (at least temporarily) a farce. It is so bad really, because there is some very cool engineer at work. Over time, we see all the impressive things that 5G has in store, but there is nothing that makes us have to go through a lot of discomfort to get there.
