Cel-Fi QUATRA Helps Brand-name Beverage Manufacturer Experience Better Cellular Coverage Inside its Plant

May 13th, 2021

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


A large beverage manufacturer with a 376,000 sq. ft. plant decided to do away with landlines, opting instead to give cell phones to its 40 managers. However, its rural location coupled with the plant’s metal roof made it nearly impossible for the managers to get a cellular signal on their phones when inside the building.

“The cellular signal from the nearby carrier towers have a really hard time penetrating a metal building,” says Mike Bozyk, co-founder of KonectaUSA, the Minnesota-based provider of indoor cellular solutions that was contracted by the beverage manufacturer to resolve the problem. “In a lot of rural areas, they are all metal – metal walls and metal roofs.”

To solve this challenge, KonectaUSA installed Cel-Fi QUATRA, an active DAS hybrid designed to bridge the price-performance gap for the middleprise. KonectaUSA chose QUATRA because, unlike analog boosters and passive DAS technology, it delivers a cellular signal that is up to 1000x stronger, utilizing CAT 5e cabling and Power over Ethernet, with no signal attenuation right to the perimeter of a building.

The Solution

According to Dave Schlange, co-founder of KonectaUSA, “We used the Cel-Fi WAVE cloud-based management platform to see the readings from the signal. We were able to determine the signal quality and strength from the antennas on front of the building were substantially better than the antennas we had mounted on the back.”

There were also considerable installation challenges inside the plant. “We needed to use a scissor lift to run cable up and down the 25 ft. high ceilings” explains Schlange. “But there were assembly belts, with bottles coming out, running 100 miles an hour. Forklifts were running all over the place. It was like rush hour.”

“I was losing sleep over how to get coverage to the production side because of the incredibly high ceiling. It would have been impossible to get a scissor lift in there and maneuver it around all the machinery and assembly belts,” says Bozyk. “Because the Cel-Fi QUATRA remote units provide coverage over a larger range than a traditional or typical cone type antenna, we got such good results that we didn’t have to go into the production areas at all to install the units. That was a huge relief. Not only did we cover more square footage, we did it quickly and with less hassle than I imagined possible.”

“Our business has grown significantly since our humble beginning. A large part of our success can be attributed to repeat business from organizations that previously had no affordable or effective means of achieving in-building cellular coverage,” says Schlange. “Once they see what we can offer, they often call us back to provide solutions for other areas, and then they refer us to their peers.”

“There’s a significant difference between quality and the number of bars on a phone,” says Schlange. “You have to be able to get the best quality signal to get the absolute best result for the customer. Cel-Fi QUATRA will help us achieve that each and every time.”
