Case Study: a major U.S. city’s airport department modernizes airport communications with SDI Presence’s digital PA system

a major U.S. city’s airport department upgrades 15,000 devices with SDI Presence

The airport department of a major U.S. city needed to replace its outdated and unreliable analog public address system across its large international airport. The department partnered with SDI Presence for a modern, integrated solution that would support emergency announcements, automated dispatch, and future expansion while ensuring campus-wide connectivity.

SDI Presence designed and implemented a new networked digital PA system, which included a fiber-optic global network and digital paging stations. The phased rollout minimized disruption, and the project included a comprehensive inventory and testing of 15,000 devices. The new system provided the airport with enhanced operational efficiency, safety, and communication reliability.
