A cost-effective solution is to use a mobile signal booster (GSM repeater). This device works by transmitting the signal from areas with strong signals to "blind spots," such as indoors, via cable.

Mobile networks and communications have become an integral part of our lives, and we only remember their existence when the connection is interrupted.

Everyone is familiar with the situation where, during an important conversation, the connection is suddenly interrupted due to insufficient signal strength or the existence of "blind spots" (where mobile communication has no signal at all).

Reasons for 3G mobile signal loss in cities: Thick glass, brick, or reinforced concrete walls of buildings can block radio waves. Even with a large number of base stations deployed in large cities, 100% coverage is not possible. Outside of cities: Radio signals weaken significantly due to distance from base stations, and natural obstacles (forests, hills) also significantly affect the signal.

GSM signal boosters operate in full-duplex mode, allowing an unlimited number of simultaneous calls. No special approval from mobile operators is required to use this device.

This mobile signal booster kit includes: an external (receiving) antenna for receiving and transmitting mobile signals from carrier base stations. It should be placed in an area with good signal reception, such as on a building's roof or wall. The GSM mobile signal booster (repeater) connects to the external antenna via cable, amplifies the signal, and then uses the internal antenna to transmit the signal to "signal dead zones" inside the building.

User signals are transmitted to mobile operators in a similar manner. Antennas inside buildings provide cellular signal coverage. Signals emitted by mobile phones inside buildings are received by the internal antennas and then transmitted to the carrier's base station via the repeater and external antenna. A power divider is needed to connect additional internal antennas to extend coverage. An RF cable is used to connect all components of the cellular signal booster. Cable length is limited by signal attenuation. The lifespan and reliability of the cellular signal booster depend on the cable brand and system installation.

Before purchasing a cell phone signal booster, you need to determine: the frequency range operated by your mobile operator (MTS, Kyivstar, Life, etc.); whether you are within your operator's coverage area; the size of the room you need to cover (the larger the area, the greater the booster power required, and vice versa); and the level and quality of outdoor signal coverage near the room (the better the outdoor signal coverage, the less booster power is needed to improve cell phone signal coverage).
