"The United States, meanwhile, enjoyed a 5G maximum speed of 1815Mbps – about three times as fast as 4G users’ maximum speed." This report seems to be lacking a reality check. (Is it practically possible to get ~600 Mbps from LTE? Exotic bundles like LTE MIMO don't really count unless they're actually offered as part of regular plans.)

At the 30.72 MS/s rate, 2k FFT size, 1201 subcarriers occupied per FFT, QAM256 on each subcarrier, 4x4 MIMO, you get ~576Mbps max throughput (pure number of bits transferred per second). This ignores encoding, cyclic prefix, and all the other overheads associated with the LTE protocol.

there's also carrier aggregation, you could multiply that throughput by the number of carrier components provided by the telco (rarely more than 2 or 3).

Well I don't know about faster than 5G, but for my rural location it's a lifesaver. I get a steady 60Mbps down, 12-15 up, which is just a tad better than my previous 0.3Mbps ADSL. It's kind of amazing and is literally what enables me to live where I do (ie. for remote work). 4g here is also far better than the shithouse fake NBN foisted on us by our far-right government, which loathes and fears any technology more re…

Good post until the last sentence! NBN history is far more interesting than that! https://en.wikipedia.org/wiki/National_Broadband_Network

It was a bit of snark not to be taken too seriously, though with regard to the trogs' fear of technology, it has more than a grain of truth ;)

Are you affected by weather? Do you use a directional antenna?

That video had so much bullshit I had to stop. 1ms ping? Get a clue dumbass. Physics.

Can you explain why 1ms ping is not possible because of physics? Otherwise this comment comes off as rather rude and unhelpful.

I bet he doesn't understand that 5G in the millimeter wave bands will have an effective coverage radius of about that of a street light. At those tiny distances 1ms is possible.

But not implemented. ALL current "5G" networks are 5G non-standalone in which 4G does all registiration with the basestation and most of the work. 5G is just a bit of extra data channel on top.

Agreed. As per the HN guidelines:

NBN ?

My residence now has NBN as an option. I have decided to wait a year or two. Going for NBN is a bit of a gamble. My OK-ish ADSL connection is finally working without interruptions, and on forums people with NBN are talking about resetting their modem several times a day, coaxial cable connections need to be perfect otherwise it doesn't work etc. Sad really to miss out, but I am prioritizing uptime over speed. The UK got this right in the late 90's by connecting cable to almost every residence (IIRC).

Fair point.

Network latency is limited by the speed of light.

Related question: what exactly is the LT in LTE supposed to mean? What's considered "long-term" here? Been confused to see 5G coming out already when 4G was supposed to be long-term.

The 5G protocol is literally named "New Radio"; if they aren't going to put much thought in to the names I'm not going to put any thought into analyzing them.

Sorry - I did not attempt to come off as rude or unhelpful.

My point is his comparison of 14ms against his expectation of 1ms. That is not realistic, given the use-case being a speed test to [semi-random] provider.

There is a physical limit in play in these scenarios - being the speed of light in a vacuum and light refraction index (fiber). Simply assuming that due to the fact that 4G is "becoming" 5G you should see an order of magnitude less latency (1ms vs 14ms) is in my view, from a physics perspective, silly.

Even including the RAN (Radio Access Network), the majority of said latency to and from the throughput server endpoint is most likely NOT the result of delay on the RAN, but rather the physical distance (proximity) from the mobile station (MS, smartphone/handset).
