Re: 240-Gbit/s sub-THz wireless communications using ultra-low phase noise receiver
#32When incorporated into Wifi 18 in the year 2046, it will prove to realistically get around 500 MB/s, and have a hard time getting through most walls.

#33I'm curious about the use cases for 275 ghz wireless communication, are microwave links still common? it's almost far infrared
By far most communication is in the microwave bands, such as WiFi, cell phones, Bluetooth
sure, but wifi doesn't go over 6ghz for plenty of reasons
edit: forgot about 60ghz wifi

#34275 GHz. Getting close to terahertz. Nice.

60GHz wifi products are pretty common now. With the notable quirk of having difficulty passing through paper.

#36They make a big point of using HD-FEC rather than SD-FEC.
To me, that makes no sense - the extra power usage of SD-FEC can be tiny, even at high data rates. The FEC problem can be parallelized (if the protocol is designed for this) so it doesn't need to run at line rate too.
(SD-FEC lets you get substantially more data throughput in a given channel).

I mean I get that series like Star Trek rely on technobabble and suspension of disbelief, but surely an enemy can just... detect the frequency, or rapidly adjust their own like tuning in until it matches?
That would work, but modern starships use a rotating phased tachyon field to prevent that.
With an inversed polarity!

Jokes aside, I get a consistent 1600mbps over wifi 6E which is good enough for me. Of course you need an AP in every room to get consistent performance, but wifi has always been like that. And unless your applications use forward error correction wifi will always have latency spikes from L2 retransmission if there's even one wall between the AP and device

Why incorporated into the light fixture?
I paid ~$280 for each U6 Enterprise and that's the only thing that limits how many I have. I'm sure it's the same for anyone that cares about wifi performance. How much of a premium would you pay for better aesthetics?

#40Does 20-m here stand for 20 meters or something else? "We also demonstrate successful 20-m transmission at a data rate of over-200 Gbit/s data rate."
Yes, it's referring to transmitting with 20 meters between transmitter/receiver. Their highest speed transfer was done at 30 centimeters between transmitter/receiver.
