Things asked in class

[c4757p]

Communication Systems to be specific.

"So, is it local governments that regulate the spectrum? So different places could have different regulations?"
"Yes."
"So if you needed a certain... uh, band? ... could you go to a different country where it isn't restricted and, like, run a landline?"

Er... what... I don't.......... what??

[mrflibble]

Just smile and nod.

[c4757p]

That's pretty much what the somewhat stunned professor did

[con-f-use]

"Are these positive or negative going through the conductor?"

Yeeeeeees, of course, you're right, exactly, good idea!

[KedasProbe]

"Yes, you can run on a landmine."

[Vgkid]

"Mrs. , are you single?"

[echen1024]

What's a soll-derr? And these Rreez-isturz? Are there like, forums and example code? Is it open source?

Must be a new thing, wired wireless...

What exactly was the student asking? Not exactly understanding the question, myself...

Theoretically, you COULD use a cross-border wired connection to exploit differences in radio regulations between 2 countries.  This actually happened here in the US back in the early days of AM broadcasting, before international telecommunications treaties had been hammered out.

The US Federal Radio Commission (precursor to the FCC) capped broadcast stations at 50kW output. A few quack doctors and bible thumping preachers set up studios in Texas, right along the Mexican border, and sent their program via phone lines to huge "Border Blaster" transmitters located on the Mexican side, running 500 kW or more, and covering huge areas of the US and even into Canada or Europe when atmospheric conditions were good.

Eventually laws were passed to prevent such arrangements, as part of the "Brinkley Act", named after an early radio medical quack it targeted, Dr. John Romulus Brinkley, who broadcast long "infomercials" for goat testicle implants and the like. He eventually had to move the entire studio to Mexico to keep the money rolling in.

Yeah, that's the point. I don't think anyone did.

Interesting bit about the Border Blasters. I'd never heard that

Never heard of Wolfman Jack?
Never watched the American Graffiti movie?

"Technically all wireless systems involve wires, e.g. the antennae."

On that one growing up I was an avid listener to Capital Radio. Only after dark though, as I was out of the ground wave coverage and had to wait for night.

Yes  It's a revolution in signal transmission, here in Italy we use it for wired WiFi and for wireless coax cables!

[XOIIO]

All the range for audiophiles will be the ability to take the convenience, easy of use and quality of sound from wireless signals, and find a way to instead transport those through wires so that the earth's magnetic field can't interfere with the waves. It will be tough to do so, but the price will surely be worth it.

Just imagine the convenience of wireless on a spool of wire.
