Cel-Fi QUATRA Increases Safety at Texas School District

The Challenge

Laredo Independent School District (ISD) is made up of 33 educational institutions including elementary, middle, and high schools, and has an annual average enrollment of 24,000 students and more than 4,500 employees. For the safety of its students and staff, the Texas-based school district sought an in-building cellular coverage solution to alleviate inadequate cellular service and provide coverage into and throughout its facilities.

Wytec International (Wytec), a member of the Safer Buildings Coalition, was selected by Laredo ISD to deploy a cellular enhancement solution designed to meet all of the school district’s technical and safety requirements.

The Solution

“The district wanted a solution that could receive signal off-air from the cellular towers and amplify the signal for all major U.S. carriers. They also required the least amount of intrusive cabling and wanted a system that could be monitored in real-time,” explains William Gray, chairman and CEO of Wytec.

“With Cel-Fi QUATRA, we were able to design a cellular enhancement solution that cost-effectively met all of the ISD’s current technical and safety requirements.”

Cel-Fi QUATRA 4000 is a hybrid Distributed Antenna System (DAS) that delivers uniform in-building cellular coverage. It specifically addresses the challenges of poor voice quality, dropped calls, and dead zones in large buildings. QUATRA delivers a cellular signal that is up to 1000x stronger than solutions based on older analog technology, offering a much larger coverage footprint.

QUATRA uses CAT 5e cabling with Power over Ethernet so there is no need to install additional power outlets for the internal remote antennas.

One Cel-Fi QUATRA Network Unit (NU) – the head end of the system – was placed in each of the buildings with the exception of the largest building, Nixon High School, which covers 200,000 square feet and where two NUs were installed. Four donor antennas were placed on the outside of each building to capture the macro signal that is then transmitted over coax cable to each of the NUs.

The Results

The installations took Wytec three weeks to complete with a team of three. After the initial campuses were completed, the ISD immediately realized the benefits of this new system. The district is now focused on complete deployment at all elementary, middle, and high school campuses which are tentatively scheduled for completion by December 2022.

“QUATRA allows us to install a system, remotely monitor it, and make adjustments if we need to. It’s a smarter solution that fits into our smart DAS product offerings.”

“The Cel-Fi QUATRA solution offers a simple, manageable system that is scalable, reliable, and carrier agnostic. The result is enterprise grade service delivery that provides consistent communications for all of our students and teachers while giving them peace of mind as they carry out their day-to-day activities at our campuses,” says Munoa.

“Cel-Fi QUATRA is a cost-effective and smart solution. It doesn’t just take what’s outside and simply blast and boost it indoors. There’s a lot of technology behind it,” says Gray.
