It’s important as we move forward that regulators be certain that unlicensed users would not compromise the integrity of this vital safety initiative. We think the FCC should adopt a “do-no-harm” position until thorough testing is completed and all parties are certain that the spectrum can be shared without interference with safety critical systems.

Importantly, auto manufacturers are moving forward with our supplier partners, Cisco and Denso, to test a potential technological solution that will allow DSRC communications without harmful interference from unlicensed devices.

If Cisco and Denso can prove that 5.9Ghz sharing will work, we may see some progress finally in deploying DSRC. The consumer segment that will gain from access to the spectrum using 802.11ac will pull things forward quickly so money can be made.
