The Cypress-Fairbanks Independent School District (CFISD) in Harris County near Houston had a communications problem.
According to a case study by audio equipment company Kenwood, the Texas school district’s two-way radios couldn’t keep up with the growth it was experiencing.
“As the school district grew, we had dead spots on campuses and were not able to communicate consistently with our campus police officers,” says Lt. Casey J. Davis, former director of emergency management for the CFISD Police Department.
Larger than the city of Denver at 186 square miles, CFISD relies heavily on two-way radios to ensure safety and security. The radios are crucial to transportation requirements for the 1,100 buses operating out of five transportation centers and to administration, engineering, and operations.
CFISD worked with Northwest Communications, a local Kenwood dealer, on a plan to deploy new communications technology, transitioning from conventional analog operation on seven UHF channels with a single 300-foot tower to NEXEDGE digital technology and multiple tower sites.
Don Cameron, president of Northwest Communications, explained that he met with the transportation department after the first tower was built, to address what they needed and got the department’s new communication system set up. He then constructed three additional towers.
“Once the infrastructure was installed and the transportation department radios were up and running, we converted the NEXEDGE radios from analog to digital during summer when schools were closed. Once that was complete, we flipped the switch, and everyone moved to digital,” he says.
By transitioning to digital communications, CFISD public safety personnel no longer must rely on industrial pool channels. The 32 channels on the towers are for district-wide communications on public safety frequencies in 450 MHz.
“These are exclusive, FB8 channels,” Cameron says. “Now, no one can talk over the police department, so that’s an extra layer of security.”
An FB8 channel is a repeater operating within a centralized trunked radio system, which provides exclusive use of the designated frequency within a geographical area, according to the Federal Communications Commission.
All CFISD buses are equipped with Kenwood NEXEDGE mobiles. Dispatch for each transportation center is set up so that when a bus driver keys up their radio, the vehicle is automatically identified. That allows campus police to immediately reroute buses if there is an emergency.
“Those incidents do occur, and we need to be able to keep the kids safe on their way to and from school, no matter what happens,” Davis says. The addition of Zonar Fleet Management further ensures accuracy in incident recording and response, according to the case study.
Communications systems for pupil transportation are more than just a way to stay connected; they can be lifesavers.
Because school bus drivers are prohibited from using mobile devices while behind the wheel, two-way radio systems remain the best form of communication. We’ve highlighted some communications systems on the market, and features that may come in handy in a life-threatening situation.
Kenwood’s single-site trunking makes it possible to create a site that is ideal for managing school bus fleets. Kenwood offers integrated system solutions.
