Internetization of the private sector

by admin

Some years ago there was a joke: "Muscovites are so stoked that they turn off their computers at night.
Those days are gone. Now, for $15 a month, everyone can get an unlimited, where you can download a movie in 15 minutes.
But, with one caveat.
If you live in a high-rise.
This does not apply to residents of the private sector. Many who live in cottages are forced to use 3G whistles. Which, although in some places promises unlimited, but either expensive, or slow, or not unlimited.
Maybe the arrival of LTE will fix the situation, but our government is too "smart". Frequencies on which this equipment could work are given to the monopoly use of the "close" companies, and they are not interested in the new technology.
Again. If I want to become a WISP. I mean a wireless internet provider. I have to buy a frequency, I have to buy a license, I have to rent towers, I have to buy equipment. All in all, I’d have to invest about $50K.
To make such an investment without a guaranteed subscriber base is not interesting to anyone.
Further, this same investment has to pay off. Meaning either in the cost of services, or in the cost of connection.
With a connection cost of $1000, you can’t get a large subscriber base.
It turns out that we have a niche that is not occupied by providers, and in which it is not at all interesting to work with licenses.
But, the solution was found. It all started with ordinary wi-fi on d-links. And, even serious companies tried to organize services on this consumer stuff.
But, for many reasons which I will not describe yet this technology is dead.
Now there was a company called ubiquiti that sold compact all-weather stations with integrated antennas for cheap.
It’s simple enough. One station hangs on a high-rise, the other on a mast at home. And we get 10-15-20 mbps in a private home. The cost of connecting to the equipment $ 200 for a single … And you can also connect the wires and the neighbors, and divide by all.
This thirst for easy profits spawned hundreds of "pioneers" who put the stations on the roof at maximum power. And riddle the airwaves with each other.
Fortunately the system turned out to be self-regulating. Noisy air forced the use of narrowly directional antennas, which collect less noise, and make less noise to others.
ubiquiti is cool, they made some good devices, but they went overboard with the advertising. They said they were selling carrier grade equipment, with TDMA protocol.
In fact, they’re still a long way from carrier-grade… and no real TDMA as in fixed wi-max…
Airmax allows you to conquer some childhood wi-fi ills and work where wi-fi would die.
ubiquiti has a major competitor. Mikrotik.
But, microtik only recently started making compact all-weather stations. And before that, it was making mostly designer elements. Separate radio card, separate, board, antenna, pigtails, housing.
Such a construction set turns out to be a little bit more expensive in some places, and in some places twice as expensive as ubiquiti analogue.
How is it attractive? Because microtic implemented their Nstreem polling protocol and the newer NV2. They didn’t shout the coveted word TDMA, but oddly enough, polling from microtic works better than polling from ubiquiti.
So, again, we have a self-regulating system. Pioneer starts with UBNT, eventually realizes that he can’t connect more people than X to one house, so he switches to microtik (or hangs a dozen stations on the neighboring house).
Eventually, he’ll probably grow to WISP level and think about buying licenses, or maybe his subscriber base will be bought out by whoever grows up first.
Who benefits from this? Ordinary people who get cheap, if not very good in some places, but for the most part, fast Internet.
Who’s on the downside? The providers who bought the 2.4 GHz frequencies. There is only one way out for them now. It’s not even just the pioneers that are the problem, it’s the frequency features and home routers.
2.4 goes through walls quite a bit, and although it’s hard to connect to a point through a wall, the millions of routers in users’ homes make a very persistent noise.
A lot more interesting is the 5 gigahertz range. At 5 gHz, the absorption is much higher. Where the interference appeared, there it dies. As a result, the ether is much cleaner and the coverage area is smaller. So you can work on less power. In addition, half the smaller wavelength leads to a reduction in the physical size of the antenna, which means that the antenna of the same size will have more gain, a smaller operating sector. More gain in the antenna means less power to the transmitter. Less noise we create.
The combination of these factors makes it almost unrealistic to corrupt the 5 gigahertz with any kind of competent approach.
