    HiBoost Smart Functions

    AGC and MGC

    HiBoost signal repeater comes with AGC circuit. It’s a smart booster function that automatically balances booster power according to outdoor signal coming from the nearest mobile operator mast. Such a thorough control of the input signal strength provides blanket protection from noise and interference with operator’s networks.

    MGC circuit allows you to regulate booster’s gain manually with two knobs below LCD screen.

    LCD Display

    To make the device use convenient, it comes equipped with real time LCD display. It shows current booster parameters such as gain, frequency and output power. The display will also warn you about performance or installation troubles with corresponding alarms.

    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 GSM signal booster improves mobile signal in your area, all your mobile devices won’t search for stronger network anymore. As a result, electromagnetic emissions will decrease and your mobile phone battery life will last longer.  

    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 DCS 1800 MHz?

    DCS 1800 MHz is 2G mobile signal standard used for voice service. It's provided by all major cellular operators in the EU and worldwide. Usually DCS 1800 MHz frequency comes as an additional frequency to GSM 900 MHz predominantly in urban areas, since GSM 900 is not enough for all mobile operators there. Still some carriers use DCS 1800 as a the main voice signal standard.
