Light has a greater frequency than 15 terahertz. tongue.gif

15 terahertz is right around where microwave radiation becomes infrared radiation, neither are harmful unless they're high power.

Well on my dual band router 5GHz can't get through the walls to my living room while 2.4GHz can.

transmission speed has little to do with the frequency or size of the wavelength... Im not sure how utilizing Thz freq's is equal to "transmitting data thousand times faster".. its just a thousand times higher frequency that is all.

 

**IMO- such high wavelengths are of little use to use for communications in hand-held devices, unless for very short paths. Obstacles like free-air loss, noise rise and thermal shift are big issues for tighter wavelengths like this... and make NO sense for reliable use with current technology. Higher wavelengths are MORE easily blocked or disturbed by obstructions like walls, and buildings... even articles like fiberglass which lower freq's shoot through just fine.

Studies are always good, but lets not go crazy because of, "omg so many hertz!"

completely harmless and relatively harmless aren't the same thing, i do agree they are relatively harmless, but those early cell phones that were putting out tons of em radiation did cause tumors, to say otherwise is just as bad as saying cigarettes don't cause cancer. . .

i'd like to know what possible side effect can be had from long term low level expose, even if it turns out the same as with newer cell phones, meaning low risk, i'll support it fully, but not before that

There has been no proof of cell phones causing cancer.

Also I would rather want to see this attention being paid to providing faster / more accessible internet for everyone in the world. Of course it won't happen, because capitalism.

The higher the frequency is, the harder it will be for the signal to pass through walls/buildings. That's why you can get a signal better from 2.4GHz routers if you're in the next room over 5GHz routers. 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.

It is actually impossible for microwave radiation to cause cancer as it is not powerful to break a chemical bond in the body (non ionising). When you increase the frequency, the wave has more energy due to E=hf, so this new super high frequency radiation will have more energy. But from its position in the EM spectrum its non ionising as well so I don't see what the fuss is about?

But limited to 500 MB download a month by carriers.
