Dedicated Short Range Communications (DSRC) Service


Dedicated Short Range Communications (DSRC) Service

On December 17, 2003 the Commission adopted a Report and Order establishing licensing and service rules for the Dedicated Short Range Communications (DSRC) Service in the Intelligent Transportation Systems (ITS) Radio Service in the 5.850-5.925 GHz band (5.9 GHz band). The DSRC Service involves vehicle-to-vehicle and vehicle-to-infrastructure communications, helping to protect the safety of the traveling public. It can save lives by warning drivers of an impending dangerous condition or event in time to take corrective or evasive actions. The band is also eligible for use by non-public safety entities for commercial or private DSRC operations.

We license DSRC Roadside Units (RSUs), communication units that are fixed along the roadside, under subpart M (Intelligent Transportation Radio Service) of Part 90 of the Commission’s Rules. We require licensees to register RSUs by site and segment(s). We license On-Board Units (OBUs), in-vehicle communications units, by rule under new subpart L of Part 95 of our Rules.
Governmental entities will be authorized a geographic-area license based on that entity’s legal jurisdictional area of operations. Non-governmental entities, will be licensed based on each applicant’s area-of-operation, i.e., by county, state, multi-state, or nationwide. Frequency coordination will not be necessary. Those applicants who are approved will each be granted a non-exclusive license for the geographic-area requested, i.e., county, state etc. Operation may not begin until licensees register RSU sites, channels, and other relevant data in the Universal Licensing System (ULS). RSUs at locations within 75 kilometers of Government radar sites are also subject to NTIA coordination. Operation may not begin until NTIA approval is received.
