900 Mhz Vs 2 4ghz Wifi Speed

By increasing the channel width, we can increase the speed and throughput of a wireless broadcast. By default, the 2.4 GHz frequency uses a 20 MHz channel width. A 20MHz channel width is wide enough to span one channel. Nov 6, 2012 - The 900 MHz frequency is better than 2.4 GHz frequency when. When too much overcrowding occurs, your WiFi network signal may be weak.

Before we charge too far ahead here, let's run over the basics. Your house or apartment, or the coffee shop you're sitting in now, is saturated with. Inconceivable numbers of them, in fact, vibrating forth from radio stations, TV stations, cellular towers, and the universe itself, into the space you inhabit. You're being bombarded, constantly, with of all kind of frequencies, many of which have been encoded with specific information, whether it be a voice, a tone, or digital data. Hell, maybe even these very words. On top of that, you're surrounded by waves of your own creation.

Inside your home are a dozen tiny little radio stations: your router, your cordless phone, your garage door opener. Anything you own that's wireless, more or less. Friggin' radio waves: they're everywhere.

Really, it's odd that your cordless phone even has that 2.4-GHz sticker. To your average, not-so-technically-inclined shopper, it's a number that means A) nothing, or B) something, but the wrong thing. That's faster than my computer!' ) What that number actually signifies is broadcast frequency, or the frequency of the waves that the phone's base station sends to its handset. In fact, the hertz itself just just a unit for frequency in any context: it's the number of times that something happens over the course of a second. In wireless communications, it refers to wave oscillation. Isadora core crack keygen autocad 2018. In computers, it refers to processor clock rates.

For TVs, the rate at which the screen refreshes; for me, clapping in front of my computer right now, it's the rate at which I'm doing so. One hertz, slow clap. The question, then, is why so many of your gadgets operate at 2.4 GHz, instead of the ~2,399,999,999 whole number frequencies below it, or any number above it. It seems almost controlled, or guided. It seems, maybe, a bit arbitrary.

It seems, well, regulated. A glance at FCC regulations confirms any suspicions. A band of frequencies clustered around 2.4 GHz has been designated, along with a handful of others, as the Industrial, Scientific, and Medical radio bands. 'A lot of the unlicensed stuff — for example, Wi-Fi — is on the 2.4-GHz or the 900-Mhz frequencies, the ISM bands. You don't need a license to operate on them.'

That's Ira Kelpz, Deputy Chief, Office of Engineering and Technology at the Federal Communications Commission, explaining precisely why these ISM bands are attractive to gadget makers: They're free to use. If routers and cordless phones and whatever else are relegated to a small band 2.4 GHz, then their radio waves won't interfere with, say, cellphones operating at 1.9 GHz, or AM radio, which broadcasts between 535 kHz and 1.7 MHz. The ISM is, in effect, a ghetto for unlicensed wireless transmission, recommended first by a quiet little agency in a Swiss office of the UN, called the ITU, then formalized, modified and codified for practical use by the governments of the world, including, of course, our own FCC.
