    HiBoost Smart Functions

    AGC and MGC

    The 3G repeater is managed by smart AGC circuit. It automatically optimizes booster power according to outdoor signal reception in your area. It protects the system from even slightest interference with mobile operators’ networks and noise.

    MGC will help you to regulate the gain value manually. It’s easy to do with two bulbs below LCD screen. 

    LCD Display

    Hi23-3G amplifier comes with user-friendly LCD display. It helps to keep an eye on current booster parameters like gain value, frequency and output power and any alarms system may detect.

    Safe and Healthy

    Certifications CE and RoHS

    Hi23-3G signal repeater  got official CE and RoHS certifications issued in accredited Phoenix Test Lab in Germany. CE and RoHS are the main European approvals which guarantee booster’s conformity with European 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

    3G booster will also protect you from mobile phone electromagnetic emissions and prolong your phone battery life. When coverage is poor in your area, your mobile device is searching for a strong network and irradiates much. Thanks to booster, signal reception gets improved while radiation gets decreased.

    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 is UMTS or 3G 2100 MHz?

    UMTS 2100 MHz is a mobile network which all major mobile operators worldwide use for 3G data transfer. The data transfer is performed on 2100 MHz frequency. The network is used by such operators as Three, EE, Orange, Vodafone, etc. UMTS 2100 MHz is easily accessible in cities, while in rural area the network can often be weak.
