Radius of the signal g by the protocol in the room. How to determine the range of wi-fi? How to increase the range of a wi-fi router using a repeater

You bought a WiFi router, installed it and used it for a while. As a result, you were not completely satisfied with his work. wireless network: low speed data transfer, poor Wi-Fi reception in the apartment, unstable signal and constant disconnections. What to do? Is it really only a replacement for a more powerful one that will help and you will have to spend a lot of money again ?!
Do not rush to run to the store for a new one. In most cases, this problem can be solved independently! Moreover, the tips and tricks below will help to strengthen the WiFi router signal even for beginners.

The first step is firmware updates.

Despite the fact that manufacturers of network gadgets are improving and trying to ensure the good quality of their products, out of the box, most routers come with semi-working software, on which some of the functions work crookedly. For example, Wi-Fi may be unstable. That is why updating the software is the first thing to start setting up a network device. Fortunately, this is done very quickly and simply. We go to the official website of the manufacturer, in the "Support" section, download latest version firmware for your device model.
After that, open the web interface of the router and find the menu section Software Update(Firmware update).

Everything is simple here: first you need to click on the "Browse" button and select the file with the firmware. And then click the "Update" button and wait until the process is completed. Usually this takes a few minutes.

Note: on the latest models routers from Zyxel, D-Link and a number of other manufacturers have already integrated the function automatic update firmware.

The user only needs to click on one button to check for updates on the site, and then another to install the update on the device.

The second step is to properly configure the WiFi hotspot.

Most users, after buying a Wi-Fi router, do not really think about the settings and leave most of the parameters at the default value.
In some cases this is sufficient. But if you want the highest speed and the largest area WiFi coverage- then you need to correctly set some parameters.

The first is the mode being used. The highest speed and best quality in the usual 2.4 GHz band can only be provided by the 802.11n. We force it.

The second is the channel width. On most Wi-Fi access points, the default width is set to 20 MHz. High speed will be only at 40 MHz.

The third is WiFi Multi-Media - WMM. This parameter is responsible for quality control for different types of traffic, and without enabling it, it will not be possible to develop top speed data transmission in a WiFi network.

The fourth is responsible for the strength of the signal emitted by the router important parameter Transmit Power.

On some models, the power is initially underestimated by up to 40%. This is enough for one room, but not enough for the whole apartment. To maximize the Wi-Fi signal of the router, set the parameter value to 100%.

Not on all devices, the power of the router is explicitly regulated. For example, on TP-Link routers this is done in the advanced settings of the WiFi network, the "Operating mode" parameter:

There are three settings available - high, medium and low power. First, set the average value and check the result. Wi-Fi coverage area is not enough - put high power and check again.

The third step is the correct location of the access point

Yes, yes, the quality of the Wi-Fi network directly depends on where the router is located. There are several common mistakes that allow when installing an access point.

The first mistake is when wireless device put under the table system unit. There are even two mistakes here - it should be placed on the contrary higher and a little further from the PC or laptop. If the client is too close to the access point, the quality of the WiFi signal will be poor.

The second common mistake is to install a router in the outermost rooms of the apartment, while it should be done as close to the center as possible. It's all about spherical wave propagation.

The Wi-Fi coverage area extends in all directions in a circle due to the fact that omnidirectional antennas are installed (narrow-directional antennas are not installed on ordinary home routers). That is why if the device is placed at the neighbor's wall, then a significant part of the coverage area will be wasted on the neighbor's apartment. We don't need this!

The fourth step is the use of additional equipment

In some cases, it is impossible to improve and strengthen the WiFi signal in an apartment without the use of additional equipment and devices.
In a private house, you can strengthen the Wi-Fi signal by replacing the antennas of the router with more powerful ones, since they are on sale.

These are special devices that connect to your wireless network and enhance the Wi-Fi coverage area, expanding it with their radio module.

P.S.: I almost forgot to consider one more case - when there are a lot of WiFi routers and neighboring access points in your neighbor's house in the usual 2.4 GHz band. The fact is that the number of free channels in this case is only 13 pieces, of which only 3 do not affect the operation of each other - 1, 6 and 11. All the rest affect the operation of devices in neighboring channels. In large cities and metropolitan areas, when searching for a wireless network, you can observe something like this:

Here already good quality you should not wait for work from a wireless network - the signal will be unstable and the connection will often break. Yes, and the speed will be low and change abruptly. On many Internet forums and blogs, they begin to advise you to play with the radio channels of the access point, change antennas, etc.
Unfortunately, all this will be in vain. The only way out of the situation is to replace the Wi-Fi router with a dual-band one that supports 5 GHz, and then switches to other frequencies. There will be no such problem here - neither you nor the neighbors will influence you!

Weak WiFi signal - actual problem for residents of apartments, country houses and office workers. Dead zones in the WiFi network are typical of both large rooms and small apartments, the area of \u200b\u200bwhich is theoretically capable of covering even a budget access point.

The range of a WiFi router is a characteristic that manufacturers cannot clearly indicate on the box: the WiFi range is affected by many factors that depend not only on the technical specifications of the device.

This article presents 10 practical advice that will help eliminate physical causes poor coverage and optimize the range of the WiFi router, it's easy to do it yourself.

The radiation of an access point in space is not a sphere, but a toroidal field resembling a donut in shape. In order for WiFi coverage within one floor to be optimal, radio waves must propagate in a horizontal plane - parallel to the floor. For this, the possibility of tilting the antennas is provided.

Antenna - the axis of the "donut". The angle of signal propagation depends on its slope.

When the antenna is tilted relative to the horizon, part of the radiation is directed outdoors: dead zones form under the “donut” plane.

A vertically mounted antenna radiates in a horizontal plane: indoors, maximum coverage is achieved.

On practice: Mounting the antenna vertically is the easiest way to optimize indoor WiFi coverage.

Place the router closer to the center of the room

Another reason for the appearance of dead zones is the poor location of the access point. An antenna radiates radio waves in all directions. In this case, the radiation intensity is maximum near the router and decreases as you approach the edge of the coverage area. If you install an access point in the center of the house, then the signal will be distributed across the rooms more efficiently.

The router, installed in the corner, gives some of the power outside the house, and the far rooms are on the edge of the coverage area.

Installation in the center of the house allows you to achieve a uniform distribution of the signal in all rooms and minimize dead zones.

In practice: Installing an access point in the “center” of the house is far from always feasible due to the complex layout, the lack of outlets in the right place, or the need to lay a cable.

Provide line of sight between router and clients

WiFi signal frequency - 2.4 GHz. These are decimeter radio waves that do not go around obstacles well and have low penetrating power. Therefore, the range and stability of the signal directly depend on the number and structure of obstacles between the access point and clients.

Passing through a wall or ceiling, an electromagnetic wave loses some of its energy.

The amount of signal attenuation depends on the material that the radio waves pass through.

* Effective distance is a value that determines how the radius of a wireless network changes in comparison with open space when a wave passes through an obstacle.

Calculation example : WiFi 802.11n signal extends in line of sight to 400 meters. After overcoming a non-permanent wall between rooms, the signal strength drops to 400 m * 15% = 60 m. The second wall will make the signal even weaker: 60 m * 15% = 9 m. The third wall makes signal reception almost impossible: 9 m * 15 % = 1.35 m.

Such calculations will help to calculate the dead zones that occur due to the absorption of radio waves by walls.

The next problem in the path of radio waves: mirrors and metal structures. Unlike walls, they do not weaken, but reflect the signal, scattering it in arbitrary directions.

Mirrors and metal structures reflect and scatter the signal, forming dead zones behind them.

If you move interior elements that reflect the signal, you can eliminate dead zones.

In practice: It is extremely rare to achieve ideal conditions when all gadgets are in direct line of sight with the router. Therefore, in a real home, each dead zone will have to be eliminated separately:

find out what interferes with the signal (absorption or reflection);
think about where to move the router (or piece of furniture).

Place the router away from sources of interference

The 2.4 GHz band does not require a license and is therefore used for the operation of household radio standards: WiFi and Bluetooth. Despite the low bandwidth, Bluetooth is still able to interfere with the router.

Green areas - stream from WiFi router. Red dots are Bluetooth data. The proximity of two radio standards in the same range causes interference that reduces the range of the wireless network.

The magnetron emits in the same frequency range. microwave oven. The radiation intensity of this device is so great that even through protective screen oven radiation of the magnetron is able to “light up” the radio beam of the WiFi router.

The radiation of the magnetron of the microwave oven causes interference interference on almost all WiFi channels.

On practice :

When using Bluetooth accessories near the router, enable the AFH parameter in the latest settings.
The microwave is a powerful source of interference, but it is not used as often. Therefore, if it is not possible to move the router, then just while preparing breakfast, you will not be able to make a Skype call.

Disable support for 802.11 b/g modes

In the 2.4 GHz band, WiFi devices of three specifications work: 802.11 b / g / n. N is latest standard and provides greater speed and range compared to B and G.

The 802.11n (2.4 GHz) specification provides longer range than the legacy B and G standards.

802.11n routers support previous WiFi standards, but the mechanics backward compatibility is such that when a B / G device appears in the coverage area of the N-router, for example, old phone or a neighbor's router - the entire network is switched to B / G mode. Physically, there is a change in the modulation algorithm, which leads to a drop in the speed and range of the router.

In practice: Switching the router to “pure 802.11n” mode will definitely have a positive effect on the quality of coverage and bandwidth of the wireless network.

However, B/G devices will not be able to connect via WiFi. If it is a laptop or TV, they can be easily connected to a router via Ethernet.

Choose the optimal WiFi channel in the settings

Almost every apartment today has a WiFi router, so the density of networks in the city is very high. The signals of neighboring access points overlap each other, taking energy from the radio path and greatly reducing its efficiency.

Neighboring networks operating on the same frequency create mutual interference interference, like circles on the water.

Wireless networks operate within range on different channels. There are 13 such channels (in Russia) and the router switches between them automatically.

To minimize interference, you need to understand which channels neighboring networks operate on and switch to a less loaded one.
Detailed instructions for setting up the channel are presented.

In practice: Choosing the least loaded channel is an effective way to expand the coverage area that is relevant for residents of an apartment building.

But in some cases, there are so many networks on the air that not a single channel gives a tangible increase in WiFi speed and range. Then it makes sense to turn to method number 2 and place the router away from the walls bordering neighboring apartments. If this does not bring results, then you should think about switching to the 5 GHz band (method No. 10).

Adjust the transmitter power of the router

The transmitter power determines the energy of the radio path and directly affects the range of the access point: the more powerful the beam, the farther it hits. But this principle is useless in the case of omnidirectional antennas of household routers: in wireless transmission, data is exchanged two-way and not only clients must “hear” the router, but vice versa.

Asymmetry: the router “reaches out” to mobile device in the back room, but does not receive a response from him due to the low power of the smartphone's WiFi module. The connection is not established.

In practice: The recommended transmitter power is 75%. It should be increased only in extreme cases: the power turned out by 100% not only does not improve the signal quality in distant rooms, but even worsens the reception stability near the router, because its powerful radio stream "clogs" the weak response signal from the smartphone.

Replace the standard antenna with a more powerful one

Most routers are equipped with standard antennas with a gain of 2 - 3 dBi. The antenna is a passive element of the radio system and is not capable of increasing the power of the stream. However, increasing the gain allows you to refocus the radio signal by changing the radiation pattern.

The higher the antenna gain, the farther the radio signal travels. At the same time, a narrower flow becomes not like a “donut”, but like a flat disk.

There is a large selection of antennas for routers with a universal SMA connector on the market.

In practice: Using a high-gain antenna is an effective way to expand the coverage area, because along with signal amplification, the antenna sensitivity increases, which means the router begins to “hear” remote devices. But due to the narrowing of the radio beam from the antenna, dead zones appear near the floor and ceiling.

Use signal repeaters

In rooms with a complex layout and multi-storey buildings, it is effective to use repeaters - devices that repeat the signal of the main router.

The simplest solution is to use an old router as a repeater. The downside of this scheme is that the throughput of the child network is half as much, because along with client data, the WDS access point aggregates the upstream from the upstream router.

Detailed setup instructions WDS bridge presented.

Dedicated repeaters are free from the problem of bandwidth cuts and are equipped with additional functionality. For example, some Asus repeater models support roaming.

In practice: No matter how complex the layout is, repeaters will help deploy a WiFi network. But any repeater is a source of interference interference. With free air, repeaters do their job well, but at high density neighboring networks the use of relay equipment in the 2.4 GHz band is impractical.

Use the 5 GHz band

Budget WiFi devices operate at 2.4 GHz, so the 5 GHz band is relatively free and has little interference.

5 GHz is a promising range. Works with gigabit streams and has an increased capacity compared to 2.4 GHz.

In practice: “Moving” to a new frequency is a radical option, requiring the purchase of an expensive dual-band router and imposing restrictions on client devices: only latest models gadgets.

The problem with WiFi signal quality is not always related to the actual range of the access point, and its solution generally comes down to two scenarios:

In a country house, it is most often required in free air conditions to cover an area that exceeds the effective range of the router.
For a city apartment, the range of a router is usually sufficient, and the main difficulty is to eliminate dead zones and interference.

The methods presented in this material will help to identify the causes of poor reception and optimize the wireless network without resorting to replacing the router or the services of paid specialists.

What a pity that wi-fi coverage cannot be ubiquitous. It’s a pity that you can’t connect to your home Wi-Fi at work - the signal doesn’t “finish off”. But what is the range (coverage) of Wi-Fi routers and what does this radius depend on? Today we will deal with this issue and learn everything about the coverage of wi-fi networks.

Radius of action wifi router- the phrase does not make sense. if we need a range, let's say to connect a network of devices spaced ten kilometers apart, this is one thing, but in this case the antenna is directed and there is no question of any radius. Or we don’t catch in the gazebo behind the bathhouse, here we are talking about the radius, but the range has nothing to do with it. because it can not catch as because of that. that the signal does not finish, and from the fact that the signal is too strong and the device “chokes” and, perhaps, to solve the problem, it will be necessary to reduce the power and range.

Since the value is spherical, the documentation usually indicates the rounded average range for two identical devices with a typical antenna. This parameter depends on the power, which cannot exceed 100 milliwatts (20 dBm) for a household router, which approximately corresponds to a range of 150 m in an open field or 50 m indoors. All these figures, as usual, are taken for an absolutely elastic spherical horse in vacuum packing. Actually, by itself - the range is a complex parameter, which includes many characteristics of both points (both the transmitter and the receiver - the reception quality is different). It is not in vain that there are Wi-Fi detectors, with which specially trained people measure the real signal level on different distances, precisely because it is easier to measure than to calculate.
We often hear from fans of one or another manufacturer that “everything is rubbish, but asus” is lying. They are shamelessly lying, all manufacturers are limited by the same top power parameter and it doesn’t matter who exactly produced Asus, Zyxel, D-link, tp-link, tenda or others. Except when both the transmitter and receiver are from the same manufacturer.

Communication on related machines will be more stable and better, all due to the fact that every eminent Chinese has his own protocol for his devices. In general, if you plan to use several connected points. it is worth choosing iron from one manufacturer, thanks to its additives to the communication standard, such a choice will make life easier in order. In all other cases, you should pay attention to the support of modes, technical parameters, the possibility of changing the firmware and other "little things" up to the possibility of connecting an external antenna (the most for range), and not to the sticker on the case, in the end, everything is done if not in one, but in neighboring factories.

However, the world of routers also has its own excellent students, for example, the same professional tool Mikrotik or ubiquiti nanostation are incomparable as a router and bypass the power limit due to their professional orientation (they have a higher ceiling).

What affects the range of a Wi-fi router

Everything affects the range of wi-fi, well, or almost everything. The main culprits are:

Frequency - the higher, the worse it spreads and is more dependent on the environment.
Protocol version 802.11 - without MIMO, an adaptive antenna is not feasible. Must be 802.11n or higher.
Power, far from always, "the more the better." Legally limited from above.
Antenna. There are a lot of things in this word - gain power, radiation pattern, matching quality. Right choice Antennas are the first thing when providing stable long-range wi-fi.
The terrain, the presence of walls, floors, flat surfaces.
Air noise.
Air humidity.

I probably forgot to mention a few factors, since the propagation of radio waves is indeed affected by most environmental parameters.

3 wi-fi routers with a long range

Let's look at wi-fi routers, the radius and range of a stable connection with which is higher than that of competitors.

MikroTik hAP AC or any other Mikrotik (preferably with a plug-in external antenna). Here and intelligent control of the antenna parameters, and transmitter power up to 1 W for some models, just remember that this is a professional tool - sometimes you have to google. The device is out of competition in terms of capabilities, hardware, flexibility, range, etc.
ASUS RT-AC3200 or any other with support for ASUS AiRadar (long-range communication stability is achieved by individually adjusting the signal to the client and emulating a directional signal).
Any three (or more) horny router with the ability to connect an external antenna instead of the standard ones.

Since the microwave is very close in physical properties, it is logical that the radius (of illumination) of the coating can be increased by raising the lamp (router). However, no one is interested in the radius, well, maybe, except for people with an absolutely round plot, the coverage area of apartments, plots that are very far from the circle, is interesting. And that is why, by limiting the radiation to the "unnecessary" side, it is possible to radically improve the situation. Even a primitive screen made from improvised materials, such as foil, can improve the reception situation. From an ordinary basin, for example, comes out a wonderful screen with the function of a focusing lens.

Turn the antennas, communication is not possible on a direct signal, it can perfectly exist on a reflected one, in addition, the antennas can simply clog each other in some positions. In the simplest case, if the device has one antenna, the antenna axis should be perpendicular to the direction of the area with the weakest reception. If the antennas are built into the router, the result may be a shift or rotation of the router. So move and measure and move again.

Buy and connect a remote antenna. In addition to the obvious function of receiving and transmitting, the antenna is also a signal amplifier. The quality of communication strongly depends on the matching of the antenna and the router, the matching also depends on the length of the connecting cable. Therefore, the calculation of the antenna should be carried out by a specialist, taking into account your personal parameters (shape of directivity, state of the air, etc.). By the way, since we are talking about antennas, here we take two beer cans, I think it’s clear that you shouldn’t expect miracles from intricate beer can designs, making and configuring such a thing is a very good auto-training and this is their main purpose.

Set the router to work in the cleanest channel. There are analyzer programs for analyzing wi-fi, they will help you choose the least noisy frequency, which will not only have a beneficial effect on the range, but also increase the speed and stability of reception.
Connect the old router as a repeater, however, more on that later.

When setting up, a sensor is desirable; a smartphone or laptop placed at the point with the weakest reception is suitable for this role. You need to download and install one of wifi programs analyzers, the task of the smartphone will be to display changes in the power of the received signal. For these purposes, the analyzer program has a network power measurement mode.

Focusing on the power readings at the point of interest, it is worth trying (if possible):

different ranges (relevant for dual-band) - the situation with the passage of the wave may be different for the 5 GHz and 2.4 GHz bands.
find a free channel in the selected range. The channel must be free, both at the point of installation of the router, and at the point of interest (it is often a situation when a remote point, where we have a tester, falls into the zone of another network at an adjacent frequency, and interference is not visible on the router, since the interfering network fails) free channels the same wifi analyzer program will show.
turning off or vice versa turning on automation, for example, selecting the “Network mode” transfer mode - sometimes the intelligence of the device is useful, but often “N Only” is more long-range.
power, the word “play” is most suitable here. The fact is that power directly affects the range. But a) it must be large enough to reach the far point, b) small enough not to interfere with the normal operation of devices near, c) a signal of different power can pass through the section in different ways.
Power control (Transmit Power) has a different logic, some manufacturers allow you to adjust the reception gain, some consider the radiation strength more important, some consider the maximum to be the norm and adjust the attenuation. Usually, in this parameter there is the word power and a scale or designation of dBm units. In any case, you need to read the documentation (for example, mikrotik has a field for specifying the range to the client in point-to-point Cell Radius mode, which cannot be lowered below 10 km, and the Tx Power Mode field, where the card rates parameter sets the maximum power to the household level of 20 dbm, precisely, so as not to jam nearby customers).
The same situation is from the category of “must try” when tuning antennas. A simple adjustment of the position of the antennas or even the location of the router can improve the quality and range of transmission by changing the environment (reducing the reflected signal, reducing distortion, avoiding obstacles). And it can only make it worse, there is no universal answer and you have to try and look at the signal changes on the test device.
Visible from afar wifi with a speed of 1kb / s is not needed by anyone. Since in general the issue of range will be raised to build a stable and fast network, it is useful not to forget about the functions that improve the stability and quality of communication. Each device has its own set, and many of these options are enabled by default. Channel width, channel extension (do not forget to make sure that the main + extension pair falls on free channels), proprietary protocols and functions - Mikrotik nv2 as an example, if, of course, the equipment allows, in general, all those goodies that the manufacturer usually boasts on the packaging .

How to increase the range of a wi-fi router using a repeater

A repeater, also known as a repeater or repeater, exists as a separate device, however, the power, and therefore the coverage of its network, leaves much to be desired. It is much more rational to use an additional router for this role. Even a very budget piece of iron will quite cope with the role of a repeater. In case of purchase, it is advisable to make sure that the selected model has this option, with hardware support, the setup comes down to pressing a couple of buttons (there are options when the hardware does not support it, but alternative firmware with this option is available). And do not forget about your protocol nuances from manufacturers, they especially like to bother with buns “for their own” Zyxel and Asus (a pair of Zyxels will work significantly better than a pair of Zyxels - Asus).

It makes no sense to describe the setting in the wizard, the repeater working as a client actually copies wifi network the main point and relays its devices connected to wi-fi automatically switch to a stronger signal.

In general, using a repeater is the most correct way to solve problems with the coverage radius, with its help you can drag the network even into a bunker with lead walls, unless of course you have one.
