Yeah. So 5G is complicated because it actually operates in three different frequency bands. So it still uses the low frequency, similar bands as 3G and 4G. It's called like the low band, like 800, 900 megahertz to two gigahertz. Then there's the sub six gigahertz band, which is kind of in between two and a half gigahertz to six gigahertz. which is new, also new, but kind of the in-between.

And then there's the millimeter waves, which everyone was really concerned about because millimeter waves are like 30, 40, maybe even up to 50 gigahertz. So we're talking about like a 10x increase in frequency. Millimeter waves. And that's referring to the wavelength. So frequency and wavelength are inversely related. Okay.

So the higher frequency you go, you get higher energy of the wavelength and then you get a shorter, sorry, you get higher energy of the wave and then you get a shorter wavelength. Okay. So that's just like when you get to 30, 40 gigahertz, it's in the millimeter wave territory as opposed to the centimeter wave territory. Got it. So it's just, yeah, different characteristics of EM waves.

And that's a big jump. It's like 10x increase all of a sudden. We've never done this. They're higher energy, so potentially higher energy is a concern. And that's fair. But the problem is, as you alluded to, it's more local. It's really more challenging because the range on the millimeter waves is terrible.

They can only go like a few hundred yards before they get eaten up by the water vapor in the air. And they get blocked by trees. They get blocked by buildings because of the characteristics of the wave at that frequency. So that's why they have to build these repeater towers everywhere. What's a repeater?

Oh, those are the 5G towers.
Oh, those are the 5G towers.
Oh, those are the 5G towers.
Yeah, the 5G towers. You know how like before you would have like one massive tower. It's like over town, over there. That's working like almost omnidirectionally where it's just spewing out like โ 3G, 4G signals in all angles, just like your Wi-Fi router is. 5G is different.
