All the Commsignia V2X OBU and RSU kits are provided with a high performing, reliable, full feature software stack which includes all the common so-called Day1 features. Further non-common Day1 and Day2 features are available separately, please contact us at sales@commsignia.com

Please note that only the features listed in the user manual of each Commsignia product listed on this site are supported, however Commsignia products may cover other features and interfaces not included in the product documentation. Commsignia shall not be liable for the use of such unsupported features, and any errors caused by the use of such features shall NOT be subject to warranty.

Commsignia participated on all the interoperability events in Europe (ETSI Plugtest series) and in the United States (OmniAir Plugfest series) which means more than nine events in the last five years. In addition to these events Commsignia participated in many undisclosed interoperability events both in the EU and US as part of projects and other pilots.

We invested a lot into being the first officially OmniAir certified V2X stack provider on the market which we successfully accomplished on May 9, 2018. As a consequence of our hard work during the initial testing period Spirent selected Commsignia V2X stack as golden sample for US/WAVE compliance testing, as a result all SW will be tested against Commsignia as the standard implementation according to Spirent.
