Frequency Coordination Information

More than 50 years ago, the American Association of State Highway and Transportation Officials (AASHTO)’s Special Committee on Com­munications was tasked with monitoring technical and regulatory matters related to telecommunications systems utilized by AASHTO members.

In 1986, at the request of the AASHTO Policy Committee, the Federal Communications Commission (FCC) designated AASHTO as the National Frequency Coordinator for the segments of the radio spectrum assigned to the public safety radio service of Highway Maintenance. In 2005, AASHTO’s frequency coordination work was contracted to RadioSoft® (a division of LS telcom).

AASHTO brings 40 years of experience in frequency coordination and is the only provider with the transpor­tation-focused background knowledge crucial for the deployment of DSRC-based communications links in Vehicle to Infrastructure (V2I) Connected-Automated Vehicle (CAV) applications. 

The FCC requires that all applications for radio station or system licenses be approved by the appropriate frequency coordination agency before submission to the FCC. AASHTO coordinates eligible highway maintenance and local government communication system frequency applications.
