Cobb County, Georgia, Doubles Radio Capacity, Increases Data Capabilities with New Public Safety Radio System from Motorola Solutions

New public safety communications system enables faster, more informed responses to emergencies


Motorola Solutions, Inc  has implemented a new public safety radio system in Cobb County, Georgia, that allows multiple public safety agencies to effectively communicate with each other to quickly resolve emergency situations. With the Motorola Solutions ASTRO® 25 Phase 2 time-division multiple access (TDMA) system, Cobb County has doubled its radio channels and expanded its reach beyond the county’s borders, so its law enforcement, fire and emergency medical teams can coordinate responses with first responders in other counties when needed.

The Cobb County system is the first ASTRO 25 Phase 2 TDMA system, allowing several users to share the same frequency channel by dividing the signal into different time slots, in the State of Georgia. This updated system is considered a “regional core” system, meaning it serves an entire county as well as neighboring counties.

 By using radio spectrum more efficiently, Cobb County’s new system doubles the channels from 18 to 36, which allows more users to operate the system at one time. It also is interoperable with the Motorola Solutions’ systems used by first responders in three other neighboring counties.

While voice communications are essential, first responders increasingly use live video and other images in the field to analyze and share information. The new network enables use of this data as well as other mission-critical applications that help to improve efficiency, safety and decision-making for Cobb County first responders such as over-the-air programming, fire station alerting and weather siren alerts.

“Our recent deployment of Motorola Solutions Phase 2 TDMA technology in Cobb County has provided our users with additional radio channel resources and additional radio system networks,” said Ann Flynn, Cobb County 9-1-1 Emergency Communications Director. “ While the enhanced system will dramatically improve inter-agency communications and the ability to coordinate local and regional first responders, the real benefit will be the improved communications between those in the field, thereby ensuring a higher standard of first responder safety.”

Cobb County 9-1-1 serves a population of approximately 750,000 people and covers more than 340 square miles. The 9-1-1 center manages more than 900,000 calls for service each year through 34 dispatch positions and provides dispatch services to four law enforcement agencies and two fire departments.
