Another Lesson from Tommy Two Way: Campus radio systems present a wide range of challenges for radio communications
Building radio systems for educational institutions usually presents itself as: the bigger the campus, the more complex the system. In elementary and middle school, facilities are typically smaller buildings with smaller campuses. As the kids get aggregated into high school the size and complexity of the building changes, not to mention the drastic differences experienced in the environment, too. Each city or district can be different, but it’s common for simplex radio to radio communications to suffice in elementary and middle schools. Coverage is limited to the distance of the portables talking with each other. As we get into the High School level, coverage issues are typically encountered that require solutions to ensure communications.
High Schools, like many educational institutions, are built with brick and mortar. Along with that you’ll see the hallways lined with metal lockers. What a great environment for radio, right? Wrong. The materials used in schools, including some of the energy efficient glass, create some of the most challenging environments known to radio.
