Getting a V2X device certified.
Radio conformance is the easy part and the part every vendor budgets for. The security test cases are newer, harder, and increasingly the commercial gate — FHWA's V2X deployment funding requires IEEE 1609.2.1 compliance, which means device interaction with real SCMS providers, not a self-declaration.
Four programme types, and the security test cases are the item to lead with.
The North American certification body, running four programme types: product certification (roadside units, on-board units, modules, tolling tags and readers), qualified test equipment, field test site authorisation, and test laboratory authorisation. Streams cover C-V2X certification for OBU, RSU and module, plus tolling and RFID.
On 19 March 2024 OmniAir published updated certification test cases adding 10 mandatory and 50 optional security test cases targeting IEEE 1609.2.1 compliance — device interaction with SCMS providers, receipt of CRL and CTL updates, and interoperability with multiple certificate providers. Testing has been offered at the Mcity Plugfest in Ann Arbor with support from SCMS providers across North America, Europe and Asia. FHWA's V2X deployment funding requires 1609.2.1 compliance, which is the commercial forcing function. The US funding picture →
Named authorised test labs include TÜV Rheinland for C-V2X. OmniAir also runs free virtual V2X security testing sessions.
Vendors holding OmniAir C-V2X certifications include Cohda (first FCC-certified C-V2X roadside unit in the US), Commsignia, Yunex Traffic, IT Telecom, and Unex, which was first to achieve OmniAir C-V2X module certification. The parts behind those units →
Multi-vendor interoperability, in Europe.
ETSI Plugtests — multi-vendor PKI interoperability events in the C-ITS CMS series. The 7th CMS Plugtest (November 2019, Sophia Antipolis) tested TS 103 097 and TS 102 941 interoperability and validated the ECTL concept, with the European Commission's Joint Research Centre participating. Later editions exist; a 2025 or 2026 CMS Plugtest date could not be confirmed. Check etsi.org/events/plugtests.
C-Roads — European harmonisation and cross-border interoperability testing; WG2 Task Force 1 produces the security report. C-Roads X-Test cross-border testing, Vienna, 20–22 October 2026. The C-Roads platform →
Who makes the instruments.
Rohde & Schwarz — the CMW500 wideband radio communication tester carried the first GCF-approved C-V2X protocol conformance test package; CMX500 for 5G NR protocol conformance; SMBV100B and FSW for 802.11p signal generation and analysis. Keysight — the E6953A V2X test solution for 802.11p/DSRC/ITS-G5, with NR sidelink support in the PathWave toolchain; Keysight gained OmniAir connected-vehicle certification in February 2025. Vector CANoe.Car2x, Anritsu, dSPACE, Spirent. Current model numbers for Keysight, Anritsu and Spirent V2X testers are not verified and are described generically.
The capacity gap that has to close before October 2028.
There is currently no NABL-accredited laboratory in India with V2X test competence, and V2X equipment does not appear in the MTCTE notified list. Building that capacity is a prerequisite for the October 2028 mandate, and it is a longer lead item than the hardware.
Our view is that V2X-specific test specifications aligned with ETSI TS 102 941 and TS 103 097 should be published, and laboratory capacity built against them, before compliance is mandated rather than alongside it.
