    No stable connection in the office? Have to call back important clients all the time? Mobile signal booster HiBoost Hi23-EGSM is an innovative smart device designed to resolve poor mobile signal reception for good! The system has such a high gain and power values (75 dB, 23 dBm), that it’s able to cover indoor areas up to 3000 sq.m. The booster will be perfect for a villa, business center, supermarket, shopping malls, restaurant, etc.  
    Hi23-EGSM repeater performs at extended GSM 900 MHz signal standard, supported by all mobile operators in Europe and worldwide. If your mobile mobile operator provides 3G at UMTS 900 MHz, the device will improve 3G data download speed as well.

    HiBoost is performed in an elegant metal body and comes equipped with real time LCD display.

    Buy this booster now and level up the quality of your mobile connection!

    * Mind that the signal reception should be at least 2-3 bars outside to ensure maximum signal enhancement inside your house/office. The efficiency of the system also depends on thickness of the walls and other building features.

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


    HiBoost Smart Functions

    AGC and MGC

    The booster comes with smart software or AGC function that automatically regulates signal enhancement strength and adjusts best parameters for your area. It establishes a power balance between the booster and a mobile operator base station in order to provide more exact mobile signal amplification in your area and eliminate the risk of cell tower interference.

    MGC allows regulating booster amplification strength manually.

    LCD Display

    Intelligent LCD display helps to keep an eye on your booster performance in real time. There're three main parameters shown on the screen - frequency, gain and output power. In case the system detects any problem, an exact kind of  Alarm will be displayed (read more on this in the manual).

    Safe and Healthy

    Certifications CE and RoHS

    Be sure to stay safe and healthy in one room with a working equipment. Mobile signal booster Hi23-EGSM passed a series of quality and safety tests in German accredited test laboratories and was issued  full CE and RoHS certifications. 

    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 Phone Battery Life

    When the coverage is poor, your mobile phone spend a lot of energy to find a stronger network. Improving mobile connection quality in your area, Hi23-EGSM reduces mobile phone electromagnetic emissions. It additionally prolongs mobile phone battery life and renders your home or office environment healthier. 

    What is dBm?

    Power ratio (in decibels) of the measured power is expressed in dBm. The higher dBm number, the more powerful signal is spread.

    Consequently, 17 (20, 23) dBm is more powerful than 13 dBm. This means not only larger coverage zone, but also signal possibility to be spread in several floors, to go through walls, etc.

    What is EGSM 900 MHz?

    EGSM 900 MHz is a mobile network standard on which mobile opertors transmit voice signal or in other words provide calls. EGSM is an upgraded GSM network extended for additional 10 MHz. Currently all major mobile operators, such as Orange, Vodafone, O2, EE, etc. perform on it.

    HiBoost Hi23-EGSM amplifies cellular signals at EGSM 900 MHz. If your carrier provides voice service at EGSM 900 MHz, this mobile repeater will ensure stronger mobile signal reception all around your area.
