    *Mind that in order to provide overall signal reception in your area, you should pick up at least 2-3 bars outside it. The repeater coverage area also depends on design features of your house or other building.

    **The higher dBm number, the more powerful signal is spread.


    HiBoost Smart Functions

    AGC and MGC

    HiBoost Hi23-5S booster is empowered by intelligent software or AGC function. It adjusts the level of mobile signal amplification in your area automatically according to outdoor signal strength. Due to AGC the booster doesn’t produce almost any noise and is fully protected from interference with operator networks.

    Under LCD display there’s Manual Gain Control circuit. It allows regulating the system gain on your own manually. 

    LCD Display

    The mobile booster is equipped with LCD screen that helps to keep watch of current system parameters such as gain and frequency. In case of any system troubles it will display flashing alarms.

    Safe and Healthy


    All HiBoost models underwent safety and quality tests in German accredited test laboratory and were issued certifications of CE and RoHS compliance. The documents declare that the booster complies with European quality and safety directives.

    CE – Mandatory conformity marking for products sold within the European Economic Area since 1985. It proves that your product fulfills EU-wide safety, health and environmental protection requirements.

    RoHS – The Restriction of Hazardous Substances Directive 2002/95/EC. It restricts the use of six hazardous substances in electrical and electronic equipment: Lead (Pb), Mercury (Hg), Cadmium (Cd), Hexavalent chromium (Cr6+), Polybrominated biphenyls (PBB), Polybrominated diphenyl ether (PBDE).

    Longer Mobile Phone Battery Life

    The repeater guarantees safe signal enhancement and prolongs mobile phone battery life. When the coverage in your area is increased, your mobile device starts receiving stronger signal and spends much less battery.

    What is dBm?

    dBm is an abbreviation that stands for power ratio (in decibels) of the measured power. The higher dBm number, the more powerful signal is spread.

    Thus, 23 dBm is more powerful than 13 dBm. This means not only larger coverage area, but also signal ability to go through walls, floors, etc.

    What are GSM, DCS, WCDMA and LTE?

    GSM is the network for voice signal transmission. Two main frequencies at which mobile operators provide calls in Europe and worldwide are 900 and 1800 Mhz. GSM 900 MHz is the main signal standard available both in and out of the city and 1800 MHz usually comes as an additional one predominantly in urban areas.

    WCDMA mobile network is used for the transmission of 3G data. In certain counties and regions some carriers also provide 3G service at 900 MHz signal standard.

    4G LTE is the mobile network standard for high-speed 4G signal data transfer. There’re 3 main 4G frequencies, at which mobile operators provide 4G data service In Europe- 800, 1800 and 2600 MHz. All of them are more widespread in cities.

    Hi23-5S supports five abovementioned mobile networks and is compatible with all major mobile operators wordlwide, such as Orange, T-Mobile, Vodafone, Three, etc.
