DSRC option offers cost benefits

New analysis of V2X (vehicle to everything) conducted by ABI Research has found that the cost of implementing DSRC (dedicated short-range communication) above cellular communications is expected to be up to $15 cheaper 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 in order to prevent accidents. Up until now, the added cost of V2X, which constitutes a significant parameter, was hardly compared between DSRC and C-V2X. As vehicle manufacturers are increasingly integrating V2X in TCUs, an ABI Research study analysed the cost of adding V2X to the TCU using both technologies.

James Hodgson, senior analyst for smart mobility and automotive research at ABI Research, said, ‘We estimate that in the initial years of deployment, C-V2X plus LTE will carry a system cost between US$13.50 and US$15 higher than DSRC plus LTE. 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 challenging requirements add cost over DSRC when taking into account that V2X is safety-critical technology. The key architectural differences which impact cost according to ABI Research are LTE ruggedisation 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.
