Chicago launches new 911 dispatch system amid official concerns

Chicago has begun the rollout of a new Computer-Aided Dispatch (CAD) system for 911 calls, marking the first major technological upgrade to the city's emergency dispatch infrastructure in over 30 years. The new system, provided by CentralSquare Technologies under a nearly $75 million contract, is intended to streamline operations for police, fire, and medical services by providing a common real-time information platform. Officials estimate the upgrade could improve emergency response times by up to 33 seconds.

The implementation has faced opposition from 14 Chicago aldermen who expressed concerns regarding system stability, call handling, and the adequacy of training. In a letter to Mayor Brandon Johnson, council members warned that modernization should not compromise the safety of residents or emergency personnel, citing reports of dropped calls and delayed responses.

In response, the mayor’s office stated that the system has undergone extensive stress testing, including a simulation of 150% of the city’s peak call volume. To mitigate risks during the transition, the new CAD system will operate alongside the existing legacy system. There is currently no set date for when the new technology will fully replace the old infrastructure.
