There is, by the way, if you look on the far left side, there’s a channel that is part of U-NII-4, but it’s not going to be contiguous. U-NII-6 is in green, U-NII-7 is in yellow, and then kind of a burnt orange or something for U-NII-8. So we have our U-NII-5, that’s the ones in blue. What I’ve done is I’ve broken this big long 1200 MHz into two chunks so they fit on the screen a little better, but they go together. So let’s zoom in and look at these differently.įirst up, we’re going to look at just the US alone. And even on this screen, even if you have a high def screen, that’s a lot of information to squeeze. In between these two, there’s one that says Standard Power. They haven’t codified those yet, so I haven’t added them to the chart. A couple of other kinds countries have already jumped on board and coming fairly quickly. Those are the only two that we have data now. And so this is just showing us in this graph, the difference between FCC and ETSI, the EU. All the little numbers inside are just formulas, and so it’s a repeatable thing. This graphic is… By the way, this is done… Sorry, I’m an Excel guy, this is done in Excel. Depending on the country you’re in, you may or may not get all of this, and depending on the usage that you want for yours, you may or may not get the same amount, in the same number. Now, we can also look and see that 6 GHz has 1200 wonderful megahertz of us to play with. You can offset that by just increasing 6 dB on the transmit power of the 5 gig or taking the 2.4 down by 6 dB. The radio waves go the same, but there’s a less distance because of the receive aperture. So what you should be saying is the 5 GHz receives 6 dB less at a given distance than 2.4. If I have a 5 GHz receive aperture that’s smaller, it receives 6 dB less energy than the 2.4. The difference is all about receive aperture. If I have a radio that transmits to the same power, the energy goes the same way, all the way to the moon, all the way to Jupiter, all the way to Alpha Centauri. 2.4 and 5 gig go the exact same distance. So a lot of times people say something that’s totally wrong, like 5 gig doesn’t go as far as 2.4, and that’s a total lie. There’s a slight difference between there, not nearly as much as the difference between 2.4 and 5 gig. So when they are listening, those antennas hear more RSSI, a lot more, around 6 dB differential, just because I have a bigger aperture. The 2.4 waves have a big circle and they collect 4.9 inches, 12 centimeters or so worth of data. The size of the radio wave they’re tuned to get will collect more or less RF energy. One are antennas to have them tune properly, are tuned to the frequency, which also means that the antennas receive aperture. Like we’ve done in the other videos on the other bands, we can look and compare the difference between 2.4, bigger waves, 5 gig, smaller, and then 6 gig, slightly smaller than that. It’s more than double of what we had before. In today’s video, we’re talking about 6 GHz spectrum, 1200 MHz of new channels for us. In today’s training video, we’re going to be talking about the new 6 GHz spectrum, 1200 MHz of new channels for us. 12000 megahertz of new channels for us, this is going to be the future of Wi-Fi. In today’s training video, we were talking about the new 6GHz spectrum.
