Another question: how safe are such amplifiers for health? Where can I read about it, do not know?

A phone in your pocket is more dangerous than a repeater in 10 meters ....

Well and nevertheless ... for interest - and if without a repeater? just connect the external antenna with the internal one? They also have some amplifier too, even if they are weak.

do you believe it yourself? once again: take on one antenna and transmit to another - you need a separate device ...

I amplify the mobile signal with a repeaterGSM 900, a large enough coverage range, the signal does not disappear and you can adjust the gain mode yourself and choose the right one, set it up once and don't touch it, it works fine.

Question to the owners of Chinese repeaters gsm 900. A few days I catch on it a signal, all to no avail. I decided to ring the connectors on it, the center of the N-connectors at the input and at the output is connected with the repeater case. I guess that should not be. until it is useful to break, can anyone look at

Good day to all, whether anyone has experience using this, or similarTytsequipment? Does it make sense to take it, does it work? The signal in my house is not stable, but the modem on the 5m usb cable outside the window works fine in 3g (all divisions).



Rep: (0)
Experience is, and not small. Buying devices of this kind, you can get either an average result or not get anything and throw money away. Similar Chinese replicators, built on simple and stupid cascades, without the possibility of even manual adjustment, or adjustment at least on the board. What is sometimes very necessary. It will work and it will be, it will depend on the signal strength that the external antenna will receive and bring it to the repeater. As a rule, all the Chinese cables that come in such kits are full. And even if you received a good signal from the antenna, the cable eats everything useful. For example, a good high-frequency 5DFB cable gives an average of 0.3 dBm of signal attenuation per meter of cable, when cheap and thin Chinese gives 1 dBm per meter. 10 meters, minus 10 units, this is a serious value. If you see all the divisions behind the window, then most likely the signal is positive, but it cannot be a reference one, which the repeater needs for power swinging and opening. A modem is a primitive measurement tool, but you can still use it for approximate calculations. Of course, it would be better to know exactly what signal strength in dBm you catch with at least a modem. In some programs for modems this can be viewed in the sections of settings or diagnostics, in network states. If you have a mobile connection in your house somewhere and how it works, then in any case your task is to install and adjust the antenna as accurately as possible so that the repeater swings the power in the room and the mobile phone. always preferred the signal strength from your repeater, the location of the internal antenna is important. If the signal from the repeater will disappear and suddenly appear, then there is no talk about the stability of the connection, a permanent connection is broken when moving around the room.

Colleagues, I ask for help with a repeater.
There is a simple locus mobi 900
Works exclusively at 900 MHz.
iPhone seems to catch tele2 at 1800, in the settings there is a voice and 3G data
It turns out, if the iPhone is so configured, then the work comes from the tower 1800 and the repeater is useless?
I plan to put it on the dacha, then upon arrival - to switch the voice and data in 2G so that there is an effect?

900 MHz repeater is useless for tele2 ... they have GSM for 1800 (3G in the same place), LTE is also in other frequencies ... at least switch in the phone settings - from this tele2 will not appear at 900 MHz ...

Maybe I ask a stupid question, but is it possible to do something to catch a better 3G phone in the country house? From all that I read, the repeaters only help for calls.
And in order to have the Internet, you need to use amplifiers for modems, that is, the Internet via modem



Rep: (0)
Repeaters enhance the frequency range of mobile communications. No matter what service or operator you use. Accordingly, it does not matter the voice or data. In rare cases, there is a limitation on the simplest repeaters, for example, on the number of subscribers simultaneously talking or in the repeater's coverage area. The main thing is to choose the correct frequency range, to correctly install the antennas, well, not a little more.

I bother with this last year.
You take an external antenna, cable, adapter for your modem.
You install the antenna, you connect everything. And you start to adjust.
The main thing is if there are several basic ones - don’t look particularly at the signal parameters, with an ideal signal the Internet can work very well, it all depends on how the base line is powered by the radio path or optics. And what is the load at peak hours, this is important. If the cottage, then Saturday evening. If everything suits you, then stay at this station. No = look for another, repeat the signal here is not the most important. This is not a theory, this is a practice.
I took a mirror for myself, 1.2 meters. + 3G feed. On the head exceeds antennas such as yagi and so on. You can tune very accurately. And most importantly, if you take a plate with an irradiator, do not forget that the adjustment goes not only horizontally but also vertically, mainly DOWN. - depends on the relief of course, but do not forget the vertical.
so, I can say that where there was no 3G at all and the cellular network in the house did not work at all, I got about 4 megabits per jump, and it is very stable. With pin and directional tips, it was near megabit and very unstable. Conclusions do it yourself. good luck

Hello everyone, guys, how can I solve my problem? --- in general, I live near the zone (place of imprisonment), so they have stubs when they turn it on! No, and no Internet speed. Will I have an amplifier? Or will it also stub these amplifiers?



Rep: (0)
Most likely the amplifier will not help you. If you only take out the antenna in the zone of no interference jammers. If the distance and the amplifier allows. But if the equipment they have is powerful, then it is also particularly useless.

Good day.
Does it make sense to put a locus mobi 900 mini (internal antenna) at a signal level of 90-95 dB?
In principle, when the phone is on the window and does not touch it and talk on the headset, the signal is not bad (3-4 divisions usually). But how well at this level the amplifier will help ....

I do not really want to install a street antenna, it will be difficult to take a cable outside.

Now even 87dB shows all divisions.

Hello, the other day I ran into a problem: the hostel doesn’t catch the signal badly. Naturally began to google what to do about it. Everywhere it is suggested to wrap the modem / telephone with copper wire for amplification and stretch it out the window. I would like to know how it works and what will happen if, for example, you create from this wire like a shield (large, 15 kg) and hang it on the ceiling / wall. Will there be the same gain? And what other options are there for signal amplification?



Rep: (0)
Size in your case will not matter. I understand that you have a modem 3G. To know another model of the modem and operator. All about what you wrote, nonsense as a matter of fact, the idea for good luck. In your case, it makes sense to either make a reflective antenna on the modem, or install an external one via crc9 if there is one on the modem, or some other one. External antennas for the modem are not expensive, but the result from them will be more than from the modem in the pan :) But first, you can simply pull the modem out of the window and see if there is a result without problems. In general, the little things are all.

There is:
* Chinese GSM 900 Mhz repeater bought on aliexpress
* 3G coverage at 900 Mhz

Will the repeater amplify the 3G signal (voice, data) by 900 Mhz or only 2G?



Rep: (0)
There will be 2G and 3G. If you are sure that the operator and your device works at these frequencies, and together where it is necessary, the operator broadcasts at this frequency. Voice and data. The most important thing is that the Chinese repeater itself worked ...



Rep: (0)
All good =) The thing is: the Internet is beautiful 4G on the street, but literally through the wall barely E = (How cheap to send a signal through the window to the office? It’s cold outside =) the street and at the same window, literally in 40-50 cm, then 4G. At least 3G would be stable. Thank you.

then you can not read .... the technical support operator conceive knows only general information .... they told him once about gsm, about 2g and about 900/1800 - now he buzzes the brain with this .... well, there is no permission for the frequency for the tele2 900 MHz ....
