HiBoost SLW Smart Link user manual
The Top Signal HiBoost SLW Smart Link receives the outside cell signal, amplifies it, and rebroadcasts it inside your office through a ceiling-mounted ultra-thin or dome antenna. This allows you to stay connected in areas where cell service is poor or where your office’s building materials interfere with signals from the local cell tower.
The Top Signal HiBoost SLW Smart Link works with all major wireless carriers, including Verizon, AT&T, T-Mobile, Sprint, UScellular, and most others.
It operates on common 4G/3G cellular frequencies.
This kit gives you the choice of an outdoor directional or omnidirectional antenna and an indoor ultra-thin dome or regular dome antenna. Here are some general guidelines for selecting the right antennas.
Outside (donor) antenna:
Inside (broadcast) antenna:
If you’re still not certain which antennas will work best for you, please call us at 866‑912‑3444. Our technical support representatives will be happy to discuss your specific requirements and give you a recommendation based on years of professional experience.
This system comes with one ultra-thin or regular dome antenna that broadcasts improved cellular signal in a spherical pattern. With strong outside cell signal (−95 dBm RSRP or greater), you can cover up to 35,000 square feet of indoor building space with 700 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.
Powerful Signal has over a decade of experience designing and installing cellular amplification systems.
