![]() If you need to amplify only one type of signal, a single-band booster will be enough, but if you want to strengthen both calls and mobile internet you may need to buy a dual-band or tri-band repeater. ![]() The type of signal you need to boost depends on the frequency, as mobile operators use different bands to transmit GSM, 3G, 4G/LTE signals. Note: Single-band boosters amplify only one frequency. ![]() Bear in mind that each booster is designed for specific bands. If you do not want to get disappointed with the model you have chosen, it is a good idea to check in advance the working frequencies of your mobile operator. Therefore, in order to choose the right model for your needs, you first should make up your mind what area you need to cover with an improved signal. Indoor coverageĪll boosters have different indoor coverage capacity. If you are looking for a good mobile signal booster, you’d better pay attention to the following points. What to pay attention to when selecting a signal amplifier? After that the booster box amplifies the weak signal and transmits it via the other cable to the indoor antenna, whose function is to disseminate the strengthened signal over the needed area. Then it sends this signal to the booster box via the cable. The whole process starts with the outdoor antenna, which catches the existing mobile signal from the nearest base station. The working principle of any booster is very simple and understandable. Some companies may even send you mountings and other accessories, necessary for proper installation. When you unpack the order, you find a booster box itself, two or more antennas (indoor and outdoor), and cables (different ones for different antennas) for connecting all the parts of the signal amplifying system. Nowadays manufacturers offer their customers full signal amplifying kits, which include all you need for immediate installation. This means that if you have no mobile signal at all, the device will hardly help you. Your mobile phone cannot distinguish whether the signal it catches is the original one or the amplified one, as the device doesn’t alter the frequency, it only strengthens the signal quality.Īnother point to pay attention to is the fact that signal boosters operate only when there is any existing coverage, even very weak. Some amplifiers cover small areas, while others can be used for improving poor reception over huge areas. Boosters support certain frequencies, some models can be used for simultaneous amplification of several frequencies.Īnother important characteristic is the indoor coverage capacity. ![]() This device was developed to increase the existing level of mobile signal and spread it around some areas. If you often face signal problems or live in an area with poor coverage, a mobile signal booster, or amplifier as it is sometimes called, can help you. ![]() Signal booster and its working principles ![]()
