In the last 3-4 years, the popularity of wireless technologies has increased not by 2-3, but by 20-30 times. Now almost every third apartment of a typical high-rise building has a router and an active WiFi network. As a result, such a house is alive, it can be found in the reach zone of 5-6 networks, and in some cases even more than 10. Of course, this affects the signal quality negatively. No, in your apartment, especially near the router, the antennas on the indicator will show an excellent level. Only here the speed parameters will be desired. In addition, you will notice that speed drops may appear, or in general it will fall to kilobit. The user looks at the box from his router, and it usually says Wireless N150 or even N300, which means a maximum speed of up to 150 or 300 megabits per second, respectively. True, you cannot achieve these values, but of course you would like to get at least half of this.
Novice users immediately bring the router to a service that checks and gives a conclusion on the device’s full performance. More advanced users start reading articles on fine tuning such as “How to increase WiFi speed”, change antennas to more powerful ones, hang foil on them, etc. . For some time it can and will save – the signal will be better and more stable. But this is until a couple more Wi-Fi networks appear nearby and everything will start in a new way.
And the reason for this phenomenon is the bandwidth of 2, 4 GHz, clogged up. Not only do you have a bunch of “neighbors” and there are 13 available channels in our region, but microwave ovens, some models of cordless phones and a number of household appliances also shine in this range. The result will be a bad signal in the neighboring rooms of the apartment, significant speed fluctuations, short-term complete loss of communication, etc.
The only way that more and more users will be accessing in the near future is the use of WiFi devices operating in the 5 GHz band.
Now there are more and more devices available in terms of cost and operating at this frequency in the market. You can now purchase a dual-band router with support for 2, 4 GHz and 5 GHz in the range of 2500-2800 rubles. A vivid example is the D-Link DIR-825 A / D1A or ASUS RT-N53. Of course, you also need to buy a network card that can work in the same range. This is another 1200-1500. Moreover, the phrase “dual-band” implies that the router can work in the usual range of 2, 4 GHz, and in the extended – 5 GHz. Accordingly, those devices for which speed is not so important or which do not support working at the new frequency (tablets, smartphones, etc.) can be left at 2.4 GHz, and laptops and computers should already be connected to a faster network. 5 GHz.
