– Purpose to show device certification process

– Certification process & capabilities to HIA requirements, subset of the IEEE 802.11p, 1609.2, 1609.3, 1609.4 & SAE J2735 standards (as specified)

– Test Method will be developed for HIA requirements.

– HIA spec includes requirements not addressed by the 802.11, 1609, and J2735 standards (e.g., device storage, positional accuracy, packet error rate)

– Using MetLabs as initial test laboratory
