Chicago is set to transition to a new Computer-Aided Dispatch system on September 22, 2026, replacing technology that has been in use for 30 years. The Office of Emergency Management and Communications manages the project, which aims to streamline emergency responses.
Why it matters
The upgrade is intended to modernize operations and improve emergency response times by replacing systems that predate Windows 95. The project aims to enhance efficiency, though its implementation follows scrutiny from local officials regarding potential service risks.
Staff have completed over 4,600 classroom hours of instruction in preparation for the transition. The system was stress-tested against call volumes reaching 150% of the city's busiest recorded hour.
The players
Office of Emergency Management and Communications
This Chicago municipal agency is responsible for coordinating citywide emergency services and managing the new dispatch technology.
The details
The Office of Emergency Management and Communications is consolidating operations into a single platform that replaces multiple outdated tools. The existing 30-year-old system will remain active as a backup to ensure continuous coverage during the transition.
Timeline
October 2025: City workers began receiving classroom instruction.
September 22, 2026: The new 911 system begins its live transition phase.
Seasonal Patterns
This transition marks a massive technological upgrade for the city, moving away from infrastructure that predates the release of Windows 95. The implementation follows a decade-long cycle of planning and pandemic-related delays to reach current digital standards.
Residents should be aware that the city is beginning a live data simulation for the new 911 system starting September 22, 2026. The existing infrastructure will serve as a redundant backup to prevent service interruptions for callers during the transition.
The takeaway
The move to a modern dispatch platform is a critical step in updating the infrastructure of the city's emergency services. Officials maintain that the new system will provide faster response times once the transition is fully complete.
