The Connected Vehicle
Modern Telematics and Intelligent Transport Systems demand robust, broadband communications links to moving vehicles in harsh radio environments. These links also become safety-critical in ITS applications such as Dedicated Short Range Communications (DSRC).
Cohda Wireless has developed unique receive-side signal processing for the outdoor, mobile automotive market and instantiated this in radios that dramatically outperform all radios available in the world today. We leverage this unparalleled knowledge of how radios work in real-life to produce Connected Vehicle and Safe Vehicle applications that work in more places, more of the time.
Cohda Wireless' technology is particularly suited to safety-critical applications – it was originally developed for the most demanding mission-critical safety application of all: Public Safety.

Field Trial Results
Cohda Wireless has completed more than 300 DSRC trials, for 15 distinct DSRC use-case scenarios, in the USA, Italy and Australia. These results show that DSRC systems using WiFi chipsets are severely challenged by the combination of mobility and multipath. In contrast, the Cohda Radio provides a robust communications link with valuable time to
- deploy counter measures, and the potential to avoid a collision altogether, and/or
- transfer more data between the RSU and the Vehicle
