Defining Auto Safety of Life in 5.9 GHz

The intention of Dedicated Short Range Communications (DSRC) systems in the 5.9 GHz spectrum band is to promote the safety of life of automobile drivers, passengers and possibly even pedestrians. If there are ubiquitous deployments of this equipment and everything works correctly, these systems could help prevent car crashes from happening. This is a noble and important purpose, but a number of key questions remain.

In particular, one missing piece is a common understanding of what falls under the term “safety of life.” Given the Commission’s current proceeding on 5.9 GHz, this is a perfect time for the Federal Communications Commission to define what is and is not included within the safety-of-life category. Clarifying which DSRC functions are worthy of protection would provide certainty to automobile manufacturers and ensure the efficient use of the spectrum band.
