In modern life it is hard to imagine yourself withoutall the advantages of mobile communication and wireless Internet, especially in the country. Losing the ability to communicate does not want to, and sometimes you need to work (well, and play, of course). But when trying to explore this issue on the Internet, we are faced with a large number of different proposals. In this material we will try to briefly understand and understand how to provide yourself with communication even in hard-to-reach places.
Cellular enhancement is of two types:
3G / 4G Internet signal booster
This option is suitable for those who have many Internet users in the house, or the signal from the base station is so bad that even on the street in front of the house there is no possibility to catch a 3G / 4G signal.
Before moving on to the other optionsamplification, it is important to note that if it is difficult for you to measure and tune the equipment, companies that are professionally engaged in amplifying a cellular signal — for example, MobileBooster — can help solve the problem.
Connection option: antenna + 4G modem + router
Consider the scheme of strengthening the mobile Internet using an antenna, modem and router:
The scheme of work is very simple, we will describe it step by step:
Antenna with built-in router
A 4G modem is built into the antenna case,sometimes with a router. The purpose of such solutions is to avoid losses on the coaxial cable, increase the cable length from the antenna to the connection point and simplify cable installation, since it is more flexible.
The reverse side of this medal is all modems andRouter routers are designed to operate in temperatures ranging from 0 to 40 degrees Celsius. Therefore, such solutions live no more than two years, and in a considerable number of cases they “die” in the first winter. Also recently, reliable solutions with built-in 4G routers began to appear on the market. For example, a rather expensive Zyxel LTE7460-M608 or models of the company RF-Link R832 and RF-Link R850.
By the way! A few words about the solution presented in the picture below. From him almost no sense. If you put your modem or router on a windowsill on the second floor, where the signal level is usually better, the result will be clearly not worse, and in some cases even better.
Selection of cellular operator for 3G / 4G Internet
There is a convenient service for choosing a mobile operator.- coverage map of all operators: Beeline, Megaphone, MTS, Yota, Tele2, Skylink. You can easily determine if a 3G / 4G network is in the right place. Information is up to date and updated automatically.
GSM / 3G / 4G cellular communications enhancement using a repeater
This amplification option is necessary for those who have problems with the Internet and voice communication, that is, you have to run to the second floor or to the street to make a regular phone call.
The repeater is an intermediate betweenan external antenna directed to the base stations of cellular operators, and internal antennas that emit a signal to subscriber devices such as a smartphone, tablet, modem, router and others.
Amplifiers to give
There are no special requirements for amplifiers. This is usually one or two-band low power repeaters. They are recommended to pick up using a program that shows the frequency of the frequency range in your area. The issue of frequency selection is acute, since cellular operators work in all 5 frequency ranges, and buying an amplifier at 5 frequencies is quite expensive and unprofitable pleasure.
Because you need to spend 5-10 minutes of your life anduse the program - for example, for Android, you can download the program "Cell towers". Immediately when you start in the upper left corner you can see the frequency in MHz.
If your family uses different SIM cardsoperators will probably need a two-band repeater. For example, a repeater with frequencies of 1800 + 2100 MHz can enhance three communication standards at once - GSM, 3G, 4G.
Amplifiers for cottages
The main problem - to have time to lay cablethe tracks are at the construction stage before the final finishing, and in 95% of cases no one worries about it in advance. It is necessary to install a mobile communications enhancement system already on a fine finish, on the façades and on ventilation to lay cables and place hidden antennas.
When calculating the coverage from the internal antennathe area of coverage is laid about 100-150 square meters, provided that there is a doorway to the adjacent premises. Reinforced concrete floors practically do not make their way through the signal, therefore at least one internal antenna must be output to each floor.
According to statistics when finishing oftenthe cable from the external antenna goes down to the boiler room, where the repeater is located. And then the internal antenna is placed inside the boiler room itself or taken outside the wall to expand the coverage area, since the walls strongly absorb the signal power. At the same time, it is necessary to use high-power amplifiers to maximize the coverage area indoors.
Also a popular option for placing the main equipment - in the attic. The cable to the internal antennas is laid along the façade - for example, behind drains or through ventilation. An example of such a solution:
There are cases when it is possible to useTV network coaxial cables for connecting internal antennas in rooms where cellular communication needs to be enhanced. Although television cables of different wave resistance, in practice, this still gives a positive result.
Main installation problems
When installing repeaters one of the important pointsis the spatial separation of the external and internal antennas in order to avoid signal “looping”, at which the system will cease to function. Further on the diagram we will show the correct and incorrect installation option:
To enhance the Internet signal with a routerspecial skills are not necessary - everything is quite simple. In most cases, no frequency measurements should be done, it is enough to know that somewhere near the street there is a weak 3G / 4G signal, or to look at its presence on the coverage map. Another strong recommendation is to hang the antenna as high as possible - this greatly affects the speed of the Internet.
To enhance voice and internet withusing a repeater in the country, it is necessary to make measurements of frequencies. Nothing complicated, but it will take some time. Otherwise, you risk getting a negative effect. Play sellers online stores are not worth it: it's like that fortune telling on the coffee grounds. Installation of repeaters in the cottage is recommended to entrust experts, well, or at least ask them to help with the selection of equipment.
