    Buy this signal amplifier now and reach new heights with upgraded mobile connection!

    *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

    HiBoost Hi23-ED is powered by smart AGC function or automatic gain control. AGC identifies the strength of the outdoor mobile signal reception and balances booster power according to this value. This way it establishes a stable balance with a cell tower avoiding the risk of overlapping mobile operators’ network.

    Thanks to MGC circuit you will be able to regulate booster gain manually. The function is mostly suitable for technically savvy users.

    LCD Display

    LCD display renders booster maintenance easy and convenient. It shows main booster parameters such as frequency, gain and output power in real time and helps to keep watch on current system performance. It also assists in troubleshooting displaying what kind of malfunction occurs - ALC (low receiving signal) or ISO (not enough distance between indoor and outdoor antennas).

    Safe and Healthy

    Certifications CE and RoHS

    All Huaptec boosters are officially claimed to be compliant with the European CE and RoHS health and safety standards. The amplifiers passed the corresponding tests in the accredited test laboratory Phoenix test Lab in Germany and were issued 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

    In spite of being extremely powerful HiBoost Hi23-ED reduces excessive radiation your mobile phone emits. If signal is poor in your area, your mobile device continuously searches for a strong signal and produces heavy electromagnetic emissions. Accordingly, in the area with strong coverage you mobile phone communicates with signal in a proper way which prolongs your mobile phone life and renders your home or work environment healthier.

    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 are EGSM 900 MHz and LTE/DCS 1800 MHz?

    EGSM 900 MHz is a mobile network used to transfer voice signal from a cell tower to your mobile phone. EGSM in new version of good old GSM network extended 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 voice service on EGSM network. EGSM 900 propagates signal both in urban and rural areas, though there’re natural and artificial barriers that sometimes prevent the signal from coming inside your property.  

    DCS 1800 MHz (or GSM 1800) is a second voice network on which mobile operators transmit voice signal to your phones. The majority of mobile operators use it in addition to GSM 900 predominantly for urban areas.

    1800 MHz is also a frequency for LTE network for high-speed 4G data transmission. LTE 1800 is easy to get in cities, while it can often be rather poor or even inaccessible in rural areas.

    HiBoost Hi23-ED boosts mobile connection at EGSM/GSM/UMTS 900 MHz and DCS/LTE 1800 MHz frequencies at a time. This dual band model guarantees clear voice conversations and speedy 4G data download at a time.
