How to boost the signal of a 3G modem: options

One of the main issues that all users of the wireless Internet have to solve is how to amplify the signal of a 3G modem. The specificity in this area is such that only a small percentage of lucky users are in the zone of a stable signal of the nearest base station. The rest are forced in one way or another to improve the quality of communication, the stability of the connection and, of course, the speed of the Internet.

How to boost the signal of a 3G modem?

As it always happens, there are several ways to solve the problem of an unstable wireless connection. Some of them involve spending financial resources, sometimes quite significant, while others, on the contrary, are almost free. Usually, it is the latter that are discussed in articles on the topic "how to strengthen the signal of a 3G modem with your own hands." We list some of them:

Device selection

If you ask a question on thematic forums about how to amplify the signal of a 3G modem, then most participants will recommend one of the above methods. However, most often their effectiveness is insufficient. Perhaps the best solution is to use an external antenna. It is worth noting that not all wireless modems have the ability to connect a regular antenna. Therefore, before buying, you need to make sure that the device has a connector for an adapter for a cable - the so-called pigtail. In its absence, the question of how to amplify the signal of a 3G modem will have to be solved in other ways. In particular, craftsmen who are not afraid to lose the warranty solder the output to the connector on their own.

Antenna

The next step is to select an external antenna. Models for GSM are not suitable for CDMA or UMTS Internet - this should be remembered. The communication standard can be obtained from the operator. Antenna models differ in signal amplification. So, the -20 dBi model provides better performance than -14 dBi, but it costs more. If there are enough funds, you can use the rule "the stock does not pull the pocket."

Cable

Since its length is up to ten meters (not recommended anymore), then with poor performance, signal attenuation per unit length can negate all the advantages of an external antenna. Conclusion: it is not worth saving on the cable. You need to purchase a high-quality modification with a wave impedance of 50 ohms.

Setting and operator

After connecting the adapter, cable and antenna to the modem, the latter should be installed on a high mast and oriented to the nearest base station. That's how easy it is to increase the signal. However, this does not always allow you to increase the speed, as it depends on the workload of the operator's equipment.
