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


    HiBoost Smart Functions

    AGC and MGC

    There’s smart AGC circuit in the 3g booster. It automatically optimizes booster gain according to the signal reception in your area and prevents from interference with mobile operators’ frequencies.

    MGC will help you to regulate the gain not only automatically, but also manually, depending on the outdoor signal strength and environmental conditions. 

    LCD Display

    To make booster use super convenient Huaptec engineers equipped it with intelligent LCD display. It shows current booster parameters like gain value, frequency and output power and detects an exact kind of malfunction in case it occurs (ALC or ISO).

    Safe and Healthy

    Certifications CE and RoHS

    Hi20-3G  WCDMA repeater conforms to CE and RoHS standards. The corresponding certifications were issued in accredited Phoenix Test Lab in Germany. CE and RoHS are the main European approvals which guarantee booster’s conformity with European and international safety and quality standards. 

    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

    The system will also save you from mobile phone emissions and provide longer phone battery life. When signal coverage is poor in your area, your mobile device is searching for a strong network and irradiates much. Thanks to booster installed in the area, the coverage raises while electromagnetic emissions fall down.

    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 UMTS or 3G 2100 MHz?

    UMTS WCDMA 3G is a world standard mobile network on which all major mobile operators transfer 3G data to your mobile device. The transfer is performed on the main UMTS frequency, 2100 MHz. The network is used by such operators as Three, EE, Orange, Vodafone, etc. Some operators like Three use UMTS 2100 for calls as well.  2100 MHz is a high-range frequency easy for propagating in cities, that's why you can face 3G signal troubles in rural areas.
