A signal booster, mobile repeater or amplifier is not a luxury anymore it is most definitely a necessity.

This Smart mobile signal booster comes in a full kit with all the components for installation and use.

The system is plug-and-play and you’ll manage to mount it even without professional assistance in 4 easy steps.

STEP 1. Mount the outdoor antenna at a reasonable height.  Ideally on a pole on top of the roof pointing in the direction where signal reception outside is best and strongest.

STEP 2. Place the booster and the indoor antenna within the area where signal needs improvement.

STEP 3. Connect the antennas with the coax cables provided and plug the booster in the mains.

STEP 4. Once the booster is plugged to a power supply, you’ll then immediately start to enjoy perfect calls and blazing data download & upload speed (depending on the solution that you choose)! The system self-adjusts best parameters for your area in 30 seconds once the unit has been turned on.

Note!!! For high power models installation such as Hi20-XXX and Hi23-XXX we STRONGLY recommend to address to professional installers.

HiBoost Hi20-3S is an innovative and professional solution for mobile signal reception improvement. The equipment supports 3 frequency bands at a time and guarantees both smooth voice and speedy 3G & 4G services. With a coverage of up to 4000 sq m/ ≈43000 sq ft, the system is suitable for any large area, such as a business center, office building, restaurant, hotel, shopping mall, etc.

Thanks to Smart Link Function you can monitor and set up your booster remotely via a free mobile app.

Purchase this cellular booster now and level up your mobile signal reception!

*Mind that in order to provide overall signal reception in your area, you should pick up at least 2-3 bars outside it. The repeater coverage area also depends on design features of your house or other building.


The booster can boast of Smart Link Function or remote control ability. Thanks to Smart Link you can manage the system with a mobile app via Bluetooth, Wi-Fi or mobile Internet. The application you need is Signal Supervisor, it’s free and you can download it from Google Play or Apple Store.

Control and set up your booster anytime anywhere

Real-Time Monitoring

Displays gain, frequency, and output power to let you keep control over the current working state.

Smart Troubleshooting

Detects and shows an exact kind of malfunction (ALC or ISO) giving you the cue what is necessary to fix.

Assistance in Installation

Helps to find best point for outdoor antenna mounting basing on the output power value displayed on the screen.


Automatic Gain Control

Intelligent System Setup

After the booster is on, AGC automatically measures input signal strength and adjusts the best system parameters suitable for mobile signal reception conditions in your particular area.

Powerful Network Protection

AGC facilitates power control between the base station and a repeater to keep gain at the optimal level. This way HiBoost doesn’t overlap mobile network and keeps noise minimized.

Manual Gain Control

The function lets you thoroughly adjust mobile signal amplification power on your own manually. Recommended for advanced users.
