USB-modems are used by a lot of people.But sometimes the signal quality leaves much to be desired, and it is necessary to resort to various additional antennas and amplifiers. In the article their main types are considered.
Everyone has long known that the mobile Internet on theThe vastness of our vast homeland seems to exist, but it does not seem to exist. There is it in large settlements. And in smaller cities, you will not find it with a flashlight. The quality of 3G Internet in such cities is simply awful. Speeds are low, frequent disconnects. And all because the towers of telecom operators are at a fair distance from these cities. And what do the local people do? Wired internet is available. And if you need mobility? In this case, manufacturers, and the "folk craftsmen" themselves came up with signal amplifiers for the USB modem. What is it and where to find it? But in this we now and understand.
A modem signal amplifier is called a speciala design that allows you to "catch" a signal coming from the operator's tower and, amplifying it, transmit to the modem. Amplifiers come in different types and forms. There are devices manufactured by serious companies. And there are products of creativity of our Kulibins. Which of them work better - it's hard to say. Of course, the products of serious companies are all done beautifully and repeatedly tested under different conditions. And at "samodelkinyh" all is developed and works on "perhaps", but it is free. Which option to choose for yourself is everyone's business. All of them though somehow, but work. It remains only to figure out how good.
In general, the strange thing is this signal amplifier forUSB modem. Reviews about it are twofold. Someone likes the quality of the signal, but someone is not thrilled, because he was expecting much more. Well, let's try to understand all this and decide which amplifier to choose and whether it should be bought at all. Perhaps, it will be possible to do at all by own strength, having made the unpretentious reflector from improvised materials.
Amplifiers assembled in factories representAn external antenna with a reflector and a mount for a USB modem. They are usually done on conscience and checked many times. It is enough to deploy such an antenna in the direction of the operator's tower and connect the modem. That's the whole setup. Such signal amplifiers for the USB modem are the most acceptable. Since, if you use the products of "folk craftsmen," you can stay without a modem at all.
But, in addition to such simple antennas, there is alsoprofessional wireless solutions. So-called 3G repeaters. These devices consist of two units equipped with a Wi-Fi transmitter. One of them is exposed outside, and the second remains near the computer, and it is the modem that is connected to it. Very good solution, but quite expensive compared to conventional reflex antennas.
Now factory signal amplifiers can be bought almost everywhere in the market and in the electronics store. There are no specialized places for their sale.
The leading manufacturer of amplifiers in our countryis a factory REMO. The signal amplifier for the USB modem REMO has an attractive appearance and, what is most pleasing, works. REMO has a wide range of models. This is Connect 2.0 and Connect 3.5 and the most popular is Connect Street Mini.
The REMO plant is located in Saratov andspecializes in the production of industrial electrical equipment. But recently the plant also aimed at the mass consumer segment. Strangely enough, they began to produce exactly the amplifiers of the Internet signal. Very unusual beginning. I wonder what will happen next? The quality of all the products of the REMO plant is at an altitude. Recently, there was a modernization of production. Probably, this made it possible to produce mass-oriented goods.
The most expensive in the company's lineup is the signal amplifier for 3G-4G USB modems Connect 3.5. It was created in tandem with the American company Upvel, specializing in the production of signal amplifiers.
Among all amplifiers of the budget segment,stands out Connect Street Mini. At its fairly low price, it has very good characteristics. It is specifically designed for mobile networks in the UMTS 2100 format. However, it supports only 3G technology. Here is his "big brother" - the signal amplifier for the USB-modem Connect Street is able to work with 4G networks. But it is, accordingly, more expensive.
Connect Street Mini is convenient because it can beeasily move anywhere. Small dimensions make it very mobile. And from the mobile Internet, this is exactly what you need. Such amplifiers as Connect Street and Connect Street Mini are the most popular. A lot of space does not take, there are a penny, easy to install and configure. And most users just need simplicity without a bunch of extra "bells and whistles."
Connect 3.5 is an 4G internet signal amplifier for a USB modem with Wi-Fi router functions. In addition to amplifying the signal, it is also able to "distribute" the Internet to all devices around. Good combination of functions. In addition, the Connect 3.5 amplifier has an impact-resistant housing, which will protect it from many mechanical damages.
The dimensions of Connect 3.5 are quite compact.You can take it with you wherever you go. In general, the REMO plant has recently started producing very high-quality products. Perhaps that is why the Americans from Upvel decided to cooperate with him. In any case, the device turned out to be stylish and useful.
3G-repeaters are called complex signal amplifiersfor a USB modem that uses a Wi-Fi network to transmit the amplified signal directly to the modem. Such devices are the most expensive solution for improving communication and not everyone can afford. A bright representative of this kind of device is Nextivity Cel-Fi RS2.
Nextivity is able to work at a distance of 1.2 km from the signal source and uses a frequency of 5 MHz to transfer information between its blocks. With its task (amplification of the signal), the repeater does well.
3G-repeater, of course, a piece of convenient, but very muchexpensive. And if something else "flies" in it, it will not be easy to fix it. For now, with our Internet speed, there's no point in throwing out tons of money for such an expensive solution. Still, the speed increase from it will not be so great.
If you do not want to spend money onspecialized means of signal amplification, you can try to assemble a simple amplifier yourself. It is not necessary to expect special acceleration from him, but it is cheap and angry. But you need to know that using such signal amplifiers for a USB modem is quite dangerous. You can lose the Internet source.
Strictly speaking, using improvised means, youyou can only collect a normal reflector. But it is quite possible that just it will be enough to provide constant and fast access to the Internet.
So, what do you need to build a simple reflector?A piece of sheet aluminum (if not - you can use foil), tools for working with metal and a USB extension cable. A sheet of aluminum with a size of 20 * 20 cm must be bent into an arc so that the reception is better. After that, in the center of the sheet, you need to make fixings for the modem. Keep it tight. Otherwise, you can not see either a modem or the Internet. After everything is ready, it will be necessary to fix the structure behind the window, sending the reflector towards the operator's tower. Now we fix the modem in the holder and connect it to the USB extension cable.
This design can also be used as asignal amplifier 4G USB-modem. But you need to remember that if you live on the first floor, you can lose both the modem and the antenna. So it is desirable to clean the structure for the night.
Now the market has a lot of solutions for combatingpoor-quality radio signal. Which of them is better - it is difficult to judge. As a rule, the more expensive - the better. But not always, it is possible that a dorogus antenna will behave worse in your particular case than a homemade reflector. In this area, there is no consensus. But there are interesting proposals. For example, Connect 3.5 or Nextivity Cel-Fi RS2. The signal amplifiers for the USB modem are still rather dark, so you need to try it yourself.
