1 Hilariously, I know who Keysight is, have heard of their PNA-X, have heard of digital predistortion, and actually know a guy who will be at IMS.  I'm opposed to 6G, still.  I think Obama was probably working for the PRC military when he opened up those bands to handsets, and the PRC is probably gonna use the 6G standard to harm US aviation interests the way that 5G was so used.  (Albeit that it is genuinely a problem that certain parts of US aviation were never actually complying with the standards they purported to meet.) 

But, I also sorta want to go back to analog TV. 

Anyway, these speed tests probably require special attention to the transceivers and antennas, it is not clear to me that it makes sense to have those design choices in a retail device. 

Anyway, there is a lot that we legitimately do not know about RF bioeffects, and I think it is reasonably clear that we cannot trust researchers at universities to give us honest information about the public health consequences of 5G and 6G.  Because we know that the universities seem to be effective at collaborating with governments to suppress honest speech about biological research. 

The naive way to get a fast speed on a wireless connect is to have an extremely wide frequency range that it can use, and to do your connection measurement with the transmitter and receiver isolated inside a faraday cage. 

We have a lot better technology these days for doing very wide frequency frequency hopping in noisy environments.  So, a) 6G could maybe interfere more with older technology still in use b) handsets in an area would definitely limit effective rates c) I'm not really interested in what better hardware can do for smartphones (1), because Apple and Google can still mess up the software side enough to limit gains.  d) I think the antenna design problem for wideband, etc., is interesting.

(1) Caveat, I am not really a smartphone guy.

2 Given that if you tune a radio to a non-station part of the dial you get static.  That static is the constant background flux of EM radiation that is bombarding us all the time for all of history.  Now, I know you've read "His Master's Voice" by Stanislaw Lem, so I won't bore you by repeating the joke.

3 Also, Pixy, your blooging software rejects the Polish Dark-L when I type it.  :^P

4 Hell, half the time it rejects my carriage returns.
There should be a blank line above.

5 "Developers working on next-generation 6G wireless have achieved speeds of 280 Gbps."
Meanwhile if you're on Verizon's prepaid service, you are capped at approximately 2Mbps.
