potential buyers need to know that not all 5G networks are equal. There's the super fast mmWave (millimeter wave) 5G and the slower but more widespread Sub-6GHz 5G.






Warning long read

mmWave is kind of a pipe dream for most people on this board at this point

mmWave will never happen outside of big cities economies of scale. And that will only be certain parts of cities. Honestly it is more of a sells gimmick.

Sub 6hz and further improvements is really what helps the majority of people.

if you dont want to read you can go watch MKBHD's video on this several months back. He made it pretty clear for the layman.

Sub-6GHz networks fall somewhere in between mmWave and LTE speeds. Sprint's Sub-6GHz network (which is now T-Mobile's), for example, has seen maximum speeds of about 200Mb/s. A good LTE connection can hit those speeds, but realistically, Sub-6GHz 5G is faster than most people will see with LTE, though not reaching those incredible speeds possible with mmWave.

OpenSignal in August 2020 analyzed real-world 5G speeds in multiple countries (using smartphones that currently support 5G), and the speed results for the United States might be surprising to those who are expecting major speed gains from 5G. Average download speeds on 5GHz networks were around 50.9Mb/s, compared to 28.9 Mb/s on LTE, and that's because most of the coverage in the U.S. is Sub-6GHz at this time.


This is factually incorrect.

We are seeing speeds significantly higher than the so called 200Mbps.

How do I know this?

Ive only overseen n41 rollouts for TMO for the last year and a half.

We have seen at 4x2 MIMO 40Mhz n41 (2.5Ghz) ENDC with b66 real speeds up to 900Mbps (only limited due to back haul currently).

60 and 100Mhz carriers are currently being tested now.

We havent even begun to talk about n71 Macro sites being rolled out or future mmWave projects on tap.

In fact the big discussion across all carriers at the moment is Spectrum farming as LTE becomes the way of WCDMA. Obviously this is still very far away in terms of total removal, but as the competition heats up for 5G total coverage, these bands will become more lucrative.

5G will be irrelevant once Starlink is running globally.

Right under tower I've only seen speeds of up to 200Mbps on band 41. I hate that T Mobile is taking that away from Sprint though.

B41 is TDD.

Depending on the MIMO config and QAM.

Max actual on one carrier of 20Mhz b41 4x4 256QAM is roughly around 291Mbps with 0% BLER.

For example a similar FDD band 2 with similar config will see around 391Mbps

Current n41 40Mhz application with 4x2 MIMO 256QAM should get you 535Mbps + 391Mbps (LTE ANCHOR) ENDC. Which we have seen in Miami, Minnesota, and Chicago.

These tests were done using OOKLA (Speedtest TCP) and iperf directly (UDP)
