Properly installing and configuring a HiBoost Commercial 20K Pro is complex task, and we strongly advise a custom solution (see Best Practices, above). If you prefer to purchase this system as a standalone product, without design and installation, the kit comes with the following components:
The HiBoost Commercial 20K Pro receives the outside cell signal, amplifies it, and rebroadcasts it inside your home through a wall-mounted panel antenna. This allows you to stay connected in areas where cell service is poor, or where your home’s construction materials interfere with signals from the local cell tower.
The HiBoost Commercial 20K Pro works with all major wireless carriers:
It operates on common 4G/3G cellular frequencies.
This system comes with one panel antenna that broadcasts in a horizontal wedge shape. With strong outside cell signal (−80 dBm or greater), you can typically cover 20,000 square feet of indoor building space with 800 MHz signal. The size of the coverage area depends on many factors, including:
Substandard or inadequate conditions in any of these factors will reduce your coverage area.
