Installation and configuration of the repeater. Installing the repeater. Measurement of the GSM signal and definition of the frequencies of base stations of cellular operators

This device is a special device that allows users of Wi-Fi modems to significantly increase the area of \u200b\u200bthe territory on which the corresponding signal is distributed.

Alternative name - signal repeater. Most often, its use is relevant in large rooms, if the modem does not transmit a high-quality signal to distant rooms.

Advantages and disadvantages

Recently, such equipment is becoming increasingly popular, it is connected with the widespread wireless networks that people unfold both at home and in office space.

Among the advantages of these devices, the following positive points can be distinguished:

Installing the device in a multi-storey country house allows you to post computers in any convenient location. Regardless of the location of the modem. This advantage has already been appreciated by people who used to have computers in uncomfortable places, since a good signal was only there.
The ability to have a stable and high-quality signal in any rooms, even with thick walls and an abundance of various designs, which used to be suppressed before.
Modern design and small size allow you to harmoniously enter the device into any room, and it will be actually inconspicuous.

Certain disadvantages can occur in specific models, in general, problems or negative points during the operation of such devices was not detected, except for the reduction of the speed of the network, which is always occurring when adding additional equipment.

However, some users have experienced difficulties with the configuration of the device, so it is highly recommended to purchase only high-quality devices from official manufacturers in order to be able to support or update the firmware and software through the official website of the manufacturer.

To install, connect, and the operation of this equipment does not require any additional software or special drivers.

How to choose

The modern market offers a wide range of models that are fundamentally different from each other according to the characteristics, although it is not always visible.

For this reason, in the implementation of choice, it was best consulted with a specialist who will give advice on acquiring a specific model to meet certain requirements for the instrument, or get advice from a company manager that sells repeaters.

The following selection criteria can be distinguished from which the acquisition of a specific repeater will depend on:

Device power It depends on the conditions in which the equipment will be operated. For use in the urban apartment there is no need to overpay for heavy duty instruments, since the most common variety is also suitable. However, if you plan to install a repeater in an office space or a country house, it is recommended to make a choice in favor of more powerful devices that have a significant coverage area and maintaining a strong signal.
Availability or absence of external antennas It also depends on the place where the repeater will be installed. There are no special meaning in them, but devices with the antennas have proven their effectiveness in large areas on the area with a poor signal level.
Antennas and other repeater elements can be removable or cast type. It is recommended to choose the instruments of the first variety: the more it will be removable parts, the better because the element of the device can be replaced with a new one. This not only allows you to save funds, but also makes it possible to upgrade the signal repeater.

How to connect

Connecting the repeater is carried out in two steps:

This equipment is connected to a personal computer or laptop with a standard twisted pair.
Connecting the power supply is carried out through the PoE injector.

After it is implemented, you can proceed to the execution of the procedure below. Connecting the repeater is seen by the example of a computer with an installed Windows operating system:

Through the Start menu, you must go to the "Control Panel", where you will need to find and select a center that is responsible for networks and provide access to them.
After moving to the controls of the networks, select "Changing the Adapter Parameters" on the left side.
By selecting a string with the name "Connection on the LAN" you need to press the mouse button to call the context menu and select the "Properties" tab.
In the resulting menu, refer to the "Internet Protocol 4 (TCP / IPv4)" and by pressing the appropriate button, go to the change of its properties and parameters.
In the new menu, you must refuse to automatically get an IP address and enter all the necessary data manually. Such information as the IP address and mask is specified by the manufacturer for each individual model.

This is completed on this connection, and you can go to the process of setting up this device.

How to setup

The standard process of setting this equipment is usually as follows:

In the settings of the used browser, you must disable the use of proxy servers. After that, an IP address is entered into the address string that corresponds to the connected repeater.
In the emerging window, you need to enter the ADMIN login and password.
After executing the listed actions, the user will have access to the settings and control menu, in which you want to select the Wireless tab located on the left pane. After that, a few more new lines appear, you need to select the first one, called "Wireless Settings" to configure the repeater.
After switching to the title tab, you must find a string with the name "Operation Mode" and select the "Universal Repeater" value for it.
After confirming the change and save this parameter, a list of all networks that are in the availability of equipment will appear. It will be necessary to detect and select the desired network, then press the "Connect" key opposite it.
After saving all network settings that are automatically defined, the device must be restarted. This is done by pressing the "Reboot" button in the same menu. After rebooting the repeater, all the changes made will take effect.
After that, you will need to go to the tab with the name "Wireless Security" and set the encryption parameters and the router password. In order for the signal to appear between devices, the values \u200b\u200bof all parameters specified by the repeater must correspond to the router settings.
On this setting this equipment completed. To make sure how true it was produced, you can go to the "Status" tab in the menu. If there appears the name of the router, and there are constantly changing numbers, the repeater is configured correctly and a connection is established between it and the router.

Testing speed through repeater

After the introduction of repeaters to the modern computer market, users had an actual question about the effect of these instruments on the Internet speed. To give the most complete and reliable response to this topic, many experts conducted a whole set of testing using the AIDA 32 Network Benchmark program, which included the following activities:

Speed \u200b\u200bchecking in normal operation, the computer is connected to the router, the signal repeater is missing. The velocity was 17 Mbps.
Connecting the computer is left in the same form as the first testing, but a laptop has been added to the network that has a connection to the signal repeater. The speed decreased to a level of 12.5 Mbps.
The laptop was connected directly to the router, and the computer through the repeater, the devices were connected to each other using Patch Cord. The signal is characterized by its stability, but the speed fell to 8.5 Mbps.
Last testing consisted in the simultaneous connection of the computer and the laptop to the signal repeater, while the experimental purity was used both a wired and wireless connection method. The signal is good, but the speed fluctuates very much, constantly changing its meanings, the highest indicator reached 37 Mbps.

Subject to testing tests and, comparing them with each other, it can be concluded that the presence of a repeater in the network slightly reduces the speed, but in some cases such a measure is justified, since this device enhances the signal.

Also, as can be seen from test results, the best speed of speed saving was recorded when the computer and the laptop is connected to each other using the signal repeater and when excluding this router schema.

Probably, the situation is all familiar when the apartment does not manage to connect to the home network - so weak signal. Or when several people are sitting in the home network, because of what the download speed drops significantly. The wifi signal repeater is a wonderful way to cope with similar small neural. What it is and how it works, you will learn from this article.

What is the repeater?

Repeater Wi-Fi, also known as an amplifier, repeater or repeater, is a device that helps to a significant increase in the coating area of \u200b\u200bthe network signal. It takes a signal from the router and provides its further transmission. You just need to allocate an excess socket under it and understand the network settings. Please note that the Wi-Fi repeater is needed in the place where the main signal is still enough. At the very least, make an initial installation and setting in the active coating area, and then you can move from the outlet to the outlet to try all the relay options and find the best for your room.

The principle of work repeater

Why do you need a repeater Wi-Fi? The fact is that if you decide to go withdraw and just increase the power of the router signal, so that "caught everywhere," then there will be no good for anything good. The consumption of electricity will increase, the device will overheat, and as a result, everything will end the breakdown.

Another single remark: As we noticed above, the repeater is often called an amplifier, but it is not quite true. WiFi-REPEATER does not enhance the available signal. He only spreads it to a large area. Purchase of the repeater will not strengthen anything and will not make your Internet super-fast, but rather, on the contrary, slightly reduce the speed due to the creation of another point of distribution of the signal. But this should not be alarming - we will consider the effect of the repeater to the speed below and explain in what cases it will be insignificant.

Do you need a repeater?

Before you go on the purchase of a repeater, think: and maybe there is another solution to the problem. It is not even about mentioned above increasing the signal power, and it is rapally about what the apartment is located in the apartment. The closer to the geometric center of the space will be your device, the even the signal is broadcast in all directions. Also check which direction the router antenna is directed. For horizontal signal distribution, it must be directed upwards.

What does the repeater Wi-Fi look like?

There are different models of amplifiers. Some dimensions and shapes are somehow reminded by a mobile phone charger, only without wire. For example, the model in the figure below looks like a compact curved plate with a plug for a socket, LED indicators, a port for an Ethernet cable and a reboot button.

There are models that differ little from the router in their form.

Typically, the delivery also includes instructions, an Ethernet cable and drive drivers.

Easier simple: WPS button

On most modern devices there is a magic WPS button (or QSS on some models), which ideally is designed to significantly simplify life, but in real life, on the contrary, sometimes it creates interference in the use of the network.

If on the router, and on the repeater there is this button, then everything you need to do is first press it on one device, and then on the other. A few minutes of waiting until the Wi-Fi repeater and the router will find each other, and voila - you can work. But there are recommendations where they advise you to configure the repeater manually by selecting a specific WiFi-network to, first, reduce the number of failures in relaying, and secondly, to protect yourself. WPS technology is easily leaving. Therefore, it is often advised to disable this mode in general if you do not have to connect new devices often.

Already pay attention to that sometimes the WPS button is aligned with the reload function (Reset). It all depends on the duration of the press: if you hold your finger on the button longer, then instead of turning on the WPS, restart the repeater, and all the settings you set are reset.

How to configure wi-fi repeater manually

For a more stable signal, it is better not to rely on WPS, but to register the entire configuration manually. Connecting Wi-Fi-Repiiter is actually even easier than setting up the router. First of all, turn on the Wi-Fi repeater into the socket and connect to it through the computer using the cable or wi-fi. Then open the browser and enter the IP address in the address bar, you will find it on the reverse side of the repeater. The screen will be updated, and the form of authorization will appear. There you enter a login and password: if you have not changed anything in the router settings, then the default is admin / admin. A page with settings will open.

Here you can somehow call your repeater Wi-Fi or leave it with the factory name. Final stage - We enter a password from your Wi-fi in the required field.

What happens with the speed of the Internet?

Sometimes there are doubts about the feasibility of buying a repeater. The main argument is the signal propagation range increases, but the total speed of the Internet falls. The practice of using repeaters shows that speed fluctuations occur: any additional link in the "distribution" chain of the Internet will reduce the flow. However, the decrease is usually not so much so much to reflect on the signal power, and is largely determined by the technical characteristics of the devices in the chain. In other words, the "bug" and "brake" the Internet will not be if your devices initially catch the signal.

Router as an alternative to the reference

There is a commodity opinion that if at your home there is an unnecessary, but working router, then it is not necessary to acquire a wifi signal repeater. Many models are created so that they can perform the repeater functions, the main thing is to configure them correctly. This is a longer process than setting up a conventional repeater, but quite fulfilled on its own. Note that it is easiest to establish a connection between two devices of one manufacturer - more chances that routers will notice each other and will work smoothly. The brand also depends on the process of configuration.

First, the router you are going to use as a repeater Wi-Fi will need to be connected to a computer using a wire. Then it will be necessary to check the adapter parameters (through the "Network and Shared Access Center", in which you can get from the "Control Panel"). An IP address of 192.168.1.21 should be displayed for the device from the subnet mask 255.255.255.0.

Then, as when setting up the repeater, you will need to drive the IP address from the bottom of the device to the address bar. Use Standard Login and Password again - Admin / Admin. On the page that opens, you will need to find the "Wireless Mode" tab and go to the settings. We are interested in the "Enable WDS" option - so we will create a network that will unite two router. You will also need to change the IP address of the router, which will act as a repeater, so that you have the opportunity to enter the setup mode. You can just change the last digit or add zero after it.

After that, you need to open a list of available networks, find the necessary, select it and enter the password. By the way, do not forget to protect the network on the second router so that the connection to it is also carried out using the password. To do this, we go to the "Security Settings" and in the column "PSK encryption key" we enter our password and persist.

Now the router works as a wifi-repeater. You can disconnect from the computer and install in the right place.

Check the connection status

After you configured the repeater or router in the repeater mode, you need to check how Wi-Fi-repeater works and how well it captures the signal. It is advisable to check on all your devices - laptops, tablets, phones - whether they see the network that repeater distributes, or continue to connect to the main router (for this you can register different names in the settings). Also check whether you installed the Wi-Fi-Signal repeater for the router, if you achieve your goal to improve the quality of communication.

To do this, you can not just walk with a smartphone around the apartment and read the number of sticks in the connection, as everyone is usually done. Download one of the special applications to your device, which is able to check the signal power.

Note that if you need to expand the coverage of the network to a sufficiently large area, and even in different directions (for example, the floor is lower and in the neighboring room), then, most likely, you will have to buy two repeators.

Good day! I want to tell about the installation of a set of repeaters in the mirror at Lada Priora 2. After buying, the priors stood ordinary black mirrors, not noticeable, without repeaters. I wanted to remake on SE, but I did not want to change the mirrors yourself, since there are already heating and the electroreglining and the price of new mirrors bite. Remembering the online store site on which he constantly order parts, immediately climbed to search and found what is needed, namely the set for alterations at a rather reasonable price. After reading the reviews, I decided to take. I ordered immediately into color and with plugs on the wing, the wiring is also included.

Delivery was a transport company, the quality of the linings themselves is excellent, the packaging, too, came in the best form as a gift was a sticker. I took and rushed!

Installing a set of repeaters in Lada Lada Mirrors 2:

we remove the standard lining on the mirrors, pushing them with a screwdriver or something sharp;
how not to twist, you have to remove the door lining and the plugs of the mirrors;
we first put the repeaters themselves with diodes so that the white cable from the repeater will look up the mirror, and then the lining, applied to the mirror simply snap the hands with force;
putting on standard places next to the heating wires everything goes well;
i remember plus and minus so as not to confuse: plus a brown color, a mass of naturally black (not confused), then the wiring through the corrugation in the door is stretched into the cabin under the legs. From two sides, the wire is quite enough.
it's not so easy to drag the wires through the gum between the door and the body, but if you try everything;
it is still necessary to remove the inner plastic threshold. I repeat: since the plugs of repeaters are included in the kit, I removed the standard repeaters, but here you can already leave them and just crash into wiring, I decided not to leave them (and then a lot of things flashing - like a Christmas tree), and installed on their places plug;
scotch great grabs quickly and tightly holds, although he worked on the street;
previously heated the place of installation by the construction hairdryer, so that the metal on the wing was warm: after all, winter on the street, well, and in the summer there will be no problems;
do not forget to degrease the surface;
the wiring on the repeaters was submitted from the standard one that went into the wing, simply stretching it back to the salon and putting a twist in the shoe shrink (or on the isolent - to someone how to like);
we collect, check and enjoy mirrors with repeaters.

Installing, connecting and configuring the GSM repeater is performed using the "native" instruction attached to the product. This article provides general principles and recommendations for all products of this type that will help you save on installing the repeater.

Examples of cellular signal amplifiers are as follows.

Please note that it is impossible to include the repeater before its full installation, remember that the external and internal antennas must be separated by an obstacle shielding signal. Failure to comply with the installation order can lead to equipment breakdown.

1. The first and most important action - setting the communication standard in which your phone works at the site of the planned installation of the cellular signal amplifier. To do this, you can make a call (from your phone, from the place where you are going to install a repeater), and fix the call time. Next, you need to write a letter to your operator's service, with the number of your phone number, the number of the caller and the call time, asking for the GSM communication standard.

The method is simple, but has several minuses. Not all cellular operators respond to such requests. Request and response will take a lot of time. Well, the most important thing is in the same place, in the same operator several base stations can work, with the equipment of a different standard. You need to choose the most preferred.

The most common standard is GSM-900. He has undeniable advantages - the coverage area can reach 30-40 km from the operator's base station, which means that a standard 900 is used in the area distant from the urban trail.

DCS-1800 has a large capacity, which means the number of subscribers of the circumscribed by one base station are higher than that of GSM-900. However, with the coverage area up to 15-20 km from the operator's antenna.

The 3G standard is easily calculated by the appearance of the corresponding icon on the phone screen, in this standard not only the telephone connection, but also provides high-grade access to the Internet (in the theory, the speed can be up to 14 Mbps).

Now let's talk about how to distinguish the GSM-900 standard from DCS-1800. To do this, you need to use a phone or a special application for mobile devices that allow you to scan the cellular network for the communication standard. In this review, scan the communication standard will be using the iPhone.

Conditions: It is required to determine what kind of repeater in the country in the Leningrad region. The 3G icon appears in places, but the Internet is not needed, and the phones are planned to be used without 3G, so the data transfer and the 3G standard itself is disabled in the phone menu (settings-main cell data). Next include built-in iPhone service menu. To do this in the number set mode, we enter *3001#12345#*

and click the challenge.
Opens the service menu Field Test.

In the window that opens, we obtain data about the cell, in the area of \u200b\u200bwhich the phone is located. In the upper left corner - the signal power. Where -62 dB is a strong signal, and -105 is very weak. That is, the smaller the numeric value (minus dropped), the stronger the signal.

ARFCN (Absolute Radio Frequency Channel Number - This is the conditional number of frequency radio channel in the UMTS system, which determines the value of the carrier frequency of the radio channel).

Rooms from 1 to 124 are GSM-900 frequencies. Rooms from 975 to 1023 Neighboring frequencies used by add-ons over GSM-900 (in MHz is a range from 925 to 935), it is important to know that not all repeaters capture these frequencies.

Finally, the numbers from 512 to 885 are the frequencies of GSM-1800.

2. Installing the Outdoor Antenna of the GSM repeater. As a rule, the antenna is installed on the roof bracket, the facade of the house. It is possible to use mast or existing buildings. The direction of the antenna - towards the intended source of the signal (with the ability to adjust the direction during the testing process).

Note. Internal and external repeater antennas ideally should be separated by an obstacle that does not pass the communication signal (reinforced concrete wall, flooding of floors, etc.), it is also important to separate the horizontal planes of the antennas (outer on the roof, internal - inside the house, in its lower part of it ). Otherwise, an undesirable "echo or self-excitation effect" is possible when the repeater will enhance its own signal (a similar effect when the microphone is raised to the dynamics).

3. Installing the internal antenna. Installing in the part of your building where you will most often use a mobile phone, and the clarity repeater itself, as close as possible to this zone. Do not forget that the GSM repeater provides the most strong reception on the same floor where the GSM repeater is installed. Attenuation by 50 dB (and this is almost complete attenuation in the 900 MHz range occurs at a distance of 10 meters from the inner antenna, i.e. when using a circular oriental antenna or an omnidirectional antenna, maximum coating and a confident signal you get a circle coating zone with a radius 10 meters and an area of \u200b\u200babout 300 square meters (neglecting the characteristics of the building and radio interference).

5. Finally, turn on the power supply of the amplifier to the corresponding jack on the rear panel of the unit, and then to the source of the electric current.

6. The repeater is set. It remains to check the level of the signal in the room, try to change the direction of the outer antenna (step 15-30 degrees), the location of the internal antenna. The speed of updating data is 15-30 seconds, so turning the antenna - wait for all data updates.

Helpful information:

1. The external antenna automatically selects a stronger signal, the repeater while sets up its work in such a way that weaker signals are processed, but not in priority, the repeater does not work at full power. You may have to change the position and direction of the external antenna several times, in search of the operator and standard you need. If it does not help, try to test the operation of the repeater with the SIM card or the phone of another operator.

2. Due to the fact that both antennas (external and internal) are receiving-transmitters are very important when installing them on the recommended distance, divide them by shielding obstacle (reinforced concrete floors and walls, metal lid and so on; wood and glass - are not a serious obstacle to the spread of the radio signal). If self-excitation effect occurs, a greater separation of antennas is required, the removal of the external antenna on the mast, change the position of the internal antenna.

3. Modern cell phones work in such a way that when the 3G network signal appears (2100 MHz) of your operator, the phone automatically switches to them, leaving the signal gain zone that the repeater provides. In this case, the quality of the communication signal can be significantly worse. To avoid such unwanted switches, disconnect the 3G networks in your phone when they are not required.

4. The speed of the Internet in the frequency range is 900 MHz is determined by the technical capabilities of the operator, specify this information from its operator.

Step-by-step photo report how to install LED repeaters in mirrors on Chevrolet Lacetti. The article will be focused on the owners of Chevrolet Lacetti and partly on those who plan to establish such repeaters to their car, the principle will be the same, the differences will be only in the process of disassembly.

From which it all started ... Not so long ago, looking through a variety of chips for cars on eBay, I came across this.

LED rotor repeaters in the mirror in the form of arrows.

So the idea of \u200b\u200binstalling them in the car appeared, after which I began to go for the process itself. I will describe it in general terms. Take the basis of the analysis with the driver's mirror.

First of all, we need to separate the mirror fastening frame from the body (fixed on 4 latches), after it is required to separate the mirror itself from the frame, for which the latter heated with a hair dryer (in order to make plastic elastic).

Our mirrors are heated, and therefore they have a heating element (in the form of a film with stripes) on the back side, and the arrow itself must be installed under it. In this case, for the separation of the film, we also resort to heating with her hair dryer. And neatly, upholding the film with any sharp object, we spare it. Rock up the arrow in the required place, and the contacts of the arrow, as they are open, insulated with the help of the tape.

After we finish the film (heating element) on top of the arrow. At this moment it is worth checking the installation process by simply by connecting the arrow to the battery.

The following is the assembly process. To do this, again should be put on the mirror frame. After that, it is necessary to stretch the wires in the mirror, removing the mirror in the body from the door (remove the lining from the cabin, disconnecting the chips and unscrewing three bolts), after separating the mirror holder from the housing (unscrew the three screws) and then stretch the wire through the mirror itself.

Power is better to carry out the rotation repeater on the wing. To do this, you need to remove the turning and power our wires.

It also follows with a rigid wire through the wing (inside it) to stretch the wires to the door.

So that the wire does not hang where it fell, it is better to spend through the door through the rubber corrugation.

After reading the trim from the door in advance, stretch the wire into the door to the outer mirror.

Connect our wires and get the result!

The process itself takes about 3 hours of operation, but it is very simple for independent execution.

The light is more than good, it does not blind in the dark, but it distracts unusual. Heated at the installation site of the shooter will be slightly weakened, but it is not critical. Despite the fact that I myself understand that all this is a balobiness, but still looks cool.
