[pcmag] Cell Phone Terahertz Frequency - Page 3

post #21 of 29
Is it faster than using visible light? Seems like this would only work with unobstructed line-of-site.

*edit*
I guess a visible light data link would have to deal with a lot of interference. I wonder how many THz signals are bouncing around already, from the sun for example?

There are about a thousand different studies showing radio frequencies harming things. Everything from causing cancer in trees, to being responsible for the massive decline of honey bee's.

Same reason why 3G/4G (Verizon 4G is 700MHz for reference) technologies can be used miles away from the cell towers inside dense builds, whereas Wi-Fi only has a range of a few dozen feet and has trouble going outside your house. This frequency could probably be disrupted by morning fog.

yeah, this is probably going to be meant for short-range communication like transfering files wirelessly from a PC to a phone.

there's small chance of cell phones being hazardous to health because phone calls and text messages don't consume much bandwidth so the amplitudes are low. having a higher frequency means more information can be sent at the same amplitude, but as quentin pointed out there are limitations.

Warning: Spoiler! (Click to show)
What if it was a phone-sex call and he masturbated?

By this logic, people who live Mexico should be dead by now as their heads are probably hot all the time.

Holding a piece of plastic against your skin will do that, EM or no.

Wireless already operates at the same frequency as many microwave ovens. My wifi connection tanks every time someone uses the microwave biggrin.gif
