Cel-Fi QUATRA Helps hotel staff get cellular coverage in basement levels for the first time

July 4th, 2021

Alliance Corporation is proud to be a Value-Added Distributor for Cel-Fi products in North America. This is a repost from a Cel-Fi by Nextivity Case Study.


An international hotel chain in San Antonio, Texas has two sub-basement floors (separated by cement) that house the human resources, operations, and housekeeping departments.

The hotel installed a bi-directional amplifier (BDA) passive distributed antenna solution (DAS), but coverage was limited as the coax cables used for this solution did not reach all areas that required coverage. To extend the coverage, the hotel would have to invest in additional coax cabling and costly connectors. But even then, there would be no guarantee of uniform cellular signal throughout the basement floors due to attenuation of signal from the system headend to the antennas – a limitation of this technology.

The Solution

Hotel management called on SignalBoosters.com, a leading provider of commercial signal boosting and wireless solutions, to find out about alternative solutions. SignalBoosters.com proposed the Cel-Fi QUATRA enterprise in-building cellular solution to address the hotel chain’s cellular coverage needs.

Cel-Fi QUATRA is an active DAS hybrid that delivers a cellular signal up to 1000x stronger than other solutions, utilizing Cat5e cabling and Power over Ethernet, with no signal attenuation right to the perimeter of the building.

In addition to the cement floors and walls, there were also steel fire doors. “Normally this would present challenges,” says Brandon Davis, vice president of enterprise for SignalBoosters.com.

The Results

The ability to use Cat5e cable compared to traditional coax cable sped up the installation and kept costs down for the hotel. Cat5e cables can be up to five times less expensive than coax cables, can be extended farther, and are also simpler to use.

“Cel-Fi QUATRA is a game changer!” says Davis. “We are excited about the opportunities that both the current and future versions of the product will bring to our business and most importantly, our customers.”
