    HiBoost Smart Functions

    AGC and MGC

    Hi20-EW dual band amplifier is powered by smart MGC and AGC circuits. Thanks to AGC the booster will automatically adjust best performance according to output signal reception in your area and prevent the booster from interference with cell towers.

    With MGC function you’re able to control booster gain on your own manually.

    LCD Display

    LCD screen on the booster will let you put an eye on current booster’s frequency, gain and output power. It also displays alarms in case output power is too strong or you performed installation in a wrong way.

    Longer Phone Battery Life

    The equipment also saves you from mobile phones electromagnetic emissions and economizes your mobile phone battery. Because of better coverage in your area, your mobile phone will emit less energy to pick up strong signal and irradiate less, accordingly.        

    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 UMTS 2100 MHz?

    EGSM 900 MHz is a mobile network for transmission of voice signals. It’s an upgraded version of old GSM standard extended for additional 10MHz. Right now all mobile operators worldwide provide voice service at new EGSM 900 MHz standard (Vodafone, T-Mobile, Orange, O2, etc.).

    UMTS 2100 MHz is a mobile network for 3G data transfer to your mobile device. Cellular operators worldwide perform data at 2100 MHz frequency. While EGSM standard is equally accessible in and out of the city, 3G network is more widespread in urban areas.

    If you mobile operator(s) provide cellular and 3G signals on EGSM 900 MHz and UMTS 2100 MHz standards respectively, this dual band booster will guarantee uninterruptable voice and stable 3G mobile Internet at a time.

    I installed this model in my shop (pretty big one). Well, voice improvement is considerable even for several operators. 3g is also good. The signal is also good on a parking place that is actually not a surprise given the power of this hi-20 ew.
