Look at the Wi-Fi antenna in the distance. Robimo WiFi antenna bi-square long-range for a router with your own hands What is the required antenna in a USB wifi adapter

A WiFi antenna is a perfect solution for anyone who is trying to organize drone-free distribution of the Internet at home or on a robot, but is faced with the problem that the router’s signal does not reach, so that they can use it without problems in a remote room. However, it is not your router that is to blame, but the antenna - it was an external one, which was included before the package. One of the best solutions to improve dartless signal- The external wifi antenna has been straightened. There are several types and types of stinks that can be selected depending on your needs. And we are also able to sort out the different aspects of it.

External passive antenna for WiFi router

We first need to note that a passive antenna for a wifi router, so that it does not interfere with power supply, does not amplify the signal, but rather reduces the direct spectrum for greater reception. The intensity of this “intensity,” which is called the direct action coefficient, varies in decibels (dBi). Small external antennas are already available on many models of routers and adapters, but their thickness does not exceed 3-5 dBi, which does not allow a significant increase in the range of the drone-free signal.

That's why you need external wifi antennas. There are two types of stench below - for external and internal vikoristan, as well as all-direct and narrow-direct.

External and internal vicor antennas

  • External antennas are those that are suitable for outdoor work. The stench is protected from the influx of litter and sunny light and special fastenings for installation on the wall. You need it if you want to create a special reception area on the underside or for communication between the courthouses.
  • Internal antennas – for the vicinity of the premises. For example, if your router is installed in a remote or closed place, then such an antenna can be connected with a cable to the antenna connector of the router and led to the center of the room.

Straightened wifi antenna

This is the most livable type. The antenna that directs the wifi signal from the living room, for example, from the cabin to the garden plot, or to the balcony of the neighbor's cabin, which is directly connected to the outside dartless antenna. The range of its action can be from one to many kilometers. Golovne, so that the bait was in direct line of sight.

Internal direct wifi antennas for the router will be brown, like, for example, hanging on the wall. To prevent the transfer from going through the wall, you can connect it to the router and send it to your desktop where the laptop is placed. Or, instead, direct the antenna to the partition so that the signal passes through it, ensuring a stable connection in the courtroom. The design of such an antenna has already been made - a panel rectangular antenna, which transmits the radio signal in one direction.


Please note that the connection to the router is not provided by USB, but instead of the attached antenna that came with the router. Apparently, since she was unknown, there was no way to replace her.

There are also compact models that are suitable both for a room stand and for mounting a bell.

An all-directional wifi antenna is designed so that it evenly distributes the signal around itself. There is little reason that the signal may be interfered with by interference from other electronic devices, which is located near the apartment, or the external radios that are installed on the street. These antennas appear near the vertical line. External poles can be installed on a booth or on a vertical pole dug into the ground. Internal ones - on the table or the police, as close as possible to the center of the receiving area.

The external wifi antenna for the router is simply mounted in place of the standard socket.


Another popular type of internal all-directional wifi antennas is for mounting on a wall. You are calling to tell the fortune of the lamp. Its peculiarity is that there is a dead zone right under the antenna, and it is necessary to hang it in the place where the signal is not needed, and the signal reception will only occur over a short distance.

WiFi antenna installation

When installing any type of antenna, it is necessary to ensure that the signal is correct. In the minds of the modern world, wines can greatly reduce their effectiveness, both through the thickness of the bottles and through materials that create stench. I’ll create a table where you can understand how much access point robots consume other materials. The most important parameter here will be “ Effective stand"(EP). You need to be protected in this way. For example, the characteristics of the router indicate that it operates at 400 meters. swears in a manner that is out of sight. You are now supported by an interior wall, which has an EP of 15%. Covered: 400 m multiplied by 15% and subtracted 60 meters. Then, through a 15-20 cm wall, the router can be “shot” at least 60 meters. If you add 15-20 decibels to the new antenna, then this loss is neutralized.

DIY wifi antenna

You can build a direct-to-air Wi-Fi antenna with your own hands. Watch the video about how to create a self-made structure from an ordinary beer can.

I can’t say for sure whether this is true or nonsense - I think it’s partly reasonable. By analogy with this popular practice, you can also build a direct antenna from an all-direct one. To do this, it is enough to attach a screen behind it, which reflects, for example, the same sheet of foil. Below I will list a number of options on how to build an antenna with your own hands, which can be taken for sale.

That's all for today. You can read about ways to strengthen the signal to a 3G modem in another article on the blog.

Droneless technologies are increasingly becoming part of our everyday life. Until recently, the optimal way to connect a personal computer local measures In addition to the Internet, it was important to connect in pairs to ensure a speed of 100 Mbit/s (or whatever) and excellent stability of the work. However, progress does not stand still and the market still needs a lot of dartless devices that will ensure a smooth and reliable connection.

If you already have a droneless router (aka router) installed in your home or office, which allows you to organize dartless measure, then to connect to it personal computer Or a smart TV will require a Wi-Fi adapter. This will be a great alternative to a dart connection, which requires the labor of a robot to lay a cable.

There are hundreds of models of wi-fi adapters on the market. How do I select the model I need?

Standard Wi-Fi

We first need to comply with the required standards dartless link. Current devices can support the following standards (in order from advanced to standard): 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac.

Standards 802.11n and 802.11ac are the most current and widespread. In general, the 802.11n standard has been adopted since 2009. Narazi it's past time dartless devices encourages herself. The 802.11ac standard was adopted in 2014. devices to support Danish standard, Less stench is released and the cost of stench is, as a rule, more expensive. Other standards are respected by the old ones, and all modern devices are also supported to ensure consistency.

Below is a table that highlights the main features of various standards.

Speed ​​of a dartless connection

Shvidkistost dartless connection comply with the standard that is being maintained, as well as with the number of receiving antennas. For the 802.11n standard, the maximum transmission speed per antenna is 150 Mbit/s, for the 802.11ac standard – 433 Mbit/s.

Please note that the theoretical transmission speed for all standards is very different from the real one. According to the first wi-fi device It takes half an hour to send tributes, and half an hour to receive gifts to a friend. Therefore, the theoretical liquidity must be immediately divided by 2 (which is shown in the table). In a different way, at the same time basic information a lot of service traffic is transmitted, including that necessary to ensure portability.

This means that, in ideal minds, the speed of data transfer from one device to another will be 2-3 times lower than the theoretical one (the one indicated on the box), depending on the class of the device. Budget models, as a rule, show noticeably modest results, lower-end adapters. For obvious reasons, there may be a defect in the appearance of the walls or household appliances, and fluidity may drop a number of times.

Frequency range

Drone-free devices can currently operate in two frequency bands – 2.4 and 5 GHz.

Number of antennas

The 802.11n and 802.11ac wireless communication standards include the ability to connect multiple antennas (MIMO, meaning Multiple Input Multiple Output), which greatly increases the connection speed. The 802.11n standard allows up to 4 antennas, 802.11ac – up to eight.

To achieve maximum performance and reliability, you must choose a drone-free system with multiple antennas. As a rule, adapters and routers with multiple antennas are more expensive.

Supported OS and other equipment

Wi-Fi adapter vendors usually release drivers for their devices for the most part. operating systems. Older versions of operating systems (for example, Windows XP) may not be supported. There may also be problems with the support of devices in new operating systems.

Therefore, when choosing an adapter, you must carefully look at the list of supported “operations”.

If you buy an adapter to connect to your TV, you will not need to read the list of supported adapters on the manufacturer’s website (for its own sake).

Smart price ranges wi-fi adapters(Be warned that the price policy of the distributors may change further):

    adapters cost up to 1200 rubles. As a rule, inexpensive adapters to the 802.11n standard are available, which include either an internal antenna or 1-2 external antennas. The stated transmission speed is 150 to 300 Mbit/s. Ensure a pleasant, sweet binding at an affordable price.

    adapters range from 1200 to 2500 rubles.  These adapters are based on the 802.11ac standard, which can accommodate 1 - 2 internal or external antennas

    (depending on the type of connection). They will provide theoretical transmission speeds of 300 to 867 Mbit/s (in the 2.4 GHz and 5 GHz bands), especially faster than cheaper models.

Adapters available for over 2500 rubles support speeds up to 1300 Mbit/s and higher, 2-3 external or internal antennas can be installed. They offer maximum benefits at maximum prices. I hope this guide will help you understand the nuances dartless technologies

Please be aware of the selection of dartless devices.

  1. Principles of distant wi-fi antennas: Stagnation of reflectors. These beaters are similar to plates for satellite TV station
  2. . The stench concentrates the signal to the singer directly and, in such a manner, enhances him; to strengthen the signal wifi antenna
  3. long-range actions are effective, such as, when singing, direct the signal to the required direction;

There is no need to confirm the designation of the combined reflector and grille. Then you can strengthen the signal with an even larger world. This is the most radical way of strengthening. From the list of options, it became clear that by strengthening the signal on far away

it is necessary to concentrate it in the required direction, and in this case it is possible to select antennas of industrial production that correspond to similar benefits.

The developers of equipment for long-distance galusa are also talking about making long-distance wi-fi antennas available to companions. Next, let's look at the applications of devices and their main features.

The Wi-Fi TL-ANT5830B contains a reflector designed to direct the signal in the required direction, thus strengthening it significantly. Attach the connections yourself for a clear connection at distant destinations.

We need:
CD box.
Copper drill with a diameter of 2.5-3 mm.
CD (plays the role of a booster). You can also check it yourself from the middle.
Antenna cable.



We select the antenna itself, adjusting the dimensions.



Then we drill a hole in the center of the box with a diameter under the TV cable.


And we cut two slits, one to one at 90 degrees (the slits are required for fixing the antenna).




The head should be positioned between the extension and the antenna, approximately 15 mm.
Also, carefully open the boxes (we will put clamps in them for further fastening to the pin).





Now we glue the sticker to the bottom of the box.


We sell the cable at the back and solder the antenna (it makes no difference where to solder the central or screen wire).



We insert the antenna at the slot and fix it with hot glue on both sides.






Now we can accept the WI-FI adapter.

We clean the cable in such a way that the braiding of the screen is even below the central wire.
Approximately 5 mm is removed from the central cable. wire in insulation.

Using an awl or a sewing needle in the center of the central braid (handle with wire), carefully pierce the central wire of the adapter antenna.

Screw the antenna from the adapter.
Using an old marker, I cut a small piece of tube (which will serve as an adapter and retainer between the adapter and cable).

Please note that the latest software can be presented in demo versions and in a mentally and cost-free manner.

We'll finally get to the entrance. One of our customers, having become familiar with our device, was very concerned about the possible problems and wrote to us - you have acquired the ability to steal WiFi!

Of course, a malicious person can abuse WiFi Agent for illegal purposes. Ale, with such success you can call the sellers of juice from the one who buys juice from the new “Raskolnikov” and attacks the old pawnbroker. And the sellers of dishes were the henchmen of the evildoers. There are knives, and swings, and a terrible frying pan.

In light of the remaining laws adopted, it is necessary to note that our device does not contain any cryptographic encryption features and does not WiFi router. A USB WiFi adapter with a direct antenna WiFi Agent does not provide any means for malicious foreign measures and does not interfere with the process of crime; it is not one iota simpler than a standard laptop WiFi adapter.

We respect that the nutrition of any kind of equipment within the framework of the law is a direct obligation for the living. Therefore, of course, no matter what happens, it is necessary to remember about the legal side of nutrition.

We recommend using WiFi Agent in situations where the standard WiFi adapter of your laptop or PC accepts WiFi signal between low levels, and also during periods when you need to make use of your WiFi to the edge, standing at a great distance from the router.
