    *Mind that you should have rather good signal reception (2-3 bars) outside the house to ensure efficient coverage improvement. Building construction and its design peculiarities also influence the quality of signal amplification.

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


    HiBoost Smart Functions

    AGC and MGC

    Dual band mobile phone amplifier Hi20-ED is powered by automatic and manual gain controls (AGC and MGC) to avoid even slightest noise and interference with mobile operators’ networks. AGC automatically adjusts best parameters according to the input signal strength in your area. This way it establishes power balance between a cell tower and a booster system. 

    With the help of MGC function you can regulate booster gain on your own by hand.

    LCD Display

    LCD display shows the main booster parameters such as frequency, gain and output power in real time. It renders booster performance super convenient and helps you always to keep watch on current system performance.

    Safe and Healthy

    Certifications CE and RoHS

    All Huaptec boosters are approved of compliance with the European CE and RoHS health and safety standards. The equipment passed all the necessary tests in the accredited test laboratory Phoenix Test Lab in Germany and was granted 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

    Apart from being safe for users HiBoost Hi20-ED reduces radiation emissions by mobile phones. In the areas with weak coverage your mobile device always searches for a strong signal and spends a lot of power. When the area is well covered your home or working environment will be released from heavy electromagnetic emissions. 

    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 are EGSM 900 MHz and LTE/DCS 1800 MHz?

    EGSM 900 MHz is a mobile network used for standard voice service or calls. It’s called EGSM as it’s an extension of good old GSM network for additional 10 MHz. A few years ago the majority of mobile operators used GSM 900 MHz to provide calls to their customers. Now all of them perform on EGSM network. EGSM 900 is used to propagate signal both in urban and rural areas. Though you can still face troubles with coverage inside your property because of natural or artificial barriers.  

    DCS 1800 MHz (it’s often has a name GSM 1800) is a second voice network on which mobile operators transfer voice signals. Often EGSM/GSM 900 and 1800 come in the pair where GSM 900 is usually the leading one, while GSM 1800 is mostly additional suitable for urban areas. There’s also the same frequency for LTE 1800 network on which mobile operators transmit high-speed 4G data to your mobile phones. LTE 1800 is easy to get in cities, while it can often be rather scarce in rural areas.

    HiBoost Hi20-ED amplifies cell phone signals at EGSM/GSM/UMTS 900 MHz and DCS/LTE 1800 MHz frequencies at a time. This dual band model ensures clear voice conversations and speedy 4G data download at a time.
