New report says hybrid DSRC plus cellular stands out over C-V2X
New analysis of vehicle to everything (V2X) conducted by ABI Research finds that the cost of implementing dedicated short-range communication (DSRC) above cellular communications is expected to be $13.50-$15 lower per telematics control unit (TCU) than implementing a C-V2X solution.
The global automotive industry has been involved in extensive discussions comparing DSRC and C-V2X as technology alternatives for enabling V2X in vehicles to prevent accidents. Until now, the added cost of V2X, which constitutes a significant parameter, has been given minimal consideration regarding comparison of DSRC and C-V2X. As vehicle manufacturers are increasingly integrating V2X in telematics control units (TCUs), an ABI Research study analyzed the cost of adding V2X to the TCU using both technologies.
"We estimate that in the initial years of deployment, C-V2X plus LTE will carry a system cost between $13.50 and $15.00 higher than DSRC plus LTE," said James Hodgson, Senior Analyst for Smart Mobility & Automotive research at ABI Research. "DSRC, being the longer established and incumbent technology, has cost advantages typically associated with deployments in the field and a more competitive ecosystem.”
ABI Research's new cost analysis indicates that C-V2X's complexity and requirements add cost over DSRC when considering V2X as safety-critical technology. The key architectural differences that impact cost, according to ABI Research, are Long-Term Evolution (LTE) ruggedization and automotive qualification; the need for high-accuracy clock source; the cellular royalty scheme; and the use of WiFi, which is bundled with DSRC for free (DSRC is part of the WiFi standards family).
Because both DSRC and 4G cellular are available technologies with mature products on the market, the findings support an industry view that the hybrid model of DSRC plus cellular is simpler to design and deploy as well as more affordable.
