The study suggested that C-V2X’s complexity and requirements add cost over DSRC when considering that V2X is safety-critical technology. It showed that the key architectural differences are LTE ruggedization and automotive qualification, the need for high accuracy clock source, the cellular royalty scheme and the use of Wi-Fi which is included with DSRC for free.
James Hodgson, senior analyst for smart mobility & 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 [£9.70]and US$15 [£10] 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.”
