700 MHz

The move to a 700MHz trunked digital system will allow for seamless emergency communication between police, fire and EMS agencies in Ada County, but will also eventually allow Ada County dispatchers and emergency crews to easily talk with teams in other counties and other states when necessary.

The Ada County Sheriff's Office was the second public safety agency in the country, and the first in the state, to become licensed to operate a 700 MHz communications system, a move that resulted from mandates by the Federal Communications Commission (FCC).

The FCC has issued a deadline of December 31, 2012 for all public safety agencies to be using a communications system capable of operating using a smaller bandwidth. The Ada County 911 Communications Center expects to begin operating its 700 MHz system in October 2006, though each public safety agency in the county has until 2009 to fully make the transition.

Once the conversion to 700 MHz is complete, you will no longer be able to hear dispatch traffic on a standard analog scanner. You will need a 700 MHz trunked digital scanner to listen in.
