The National Highway Traffic Safety Administration’s proposed mandate to implement DSRC V2X (Vehicle-to-Everything) is not only moribund but has an uncertain future under the Trump administration, according to Strategy Analytics. Meanwhile a cellular technology based alternative (C-V2X) has recently been developed, with its advocates claiming it offers the high performance necessary to support V2X safety-critical applications.
The Strategy Analytics report, “Mandate Delays will Favor C-V2X in ‘Protocol War’ Battle with DSRC for V2X Implementations,”, analyzes the latest developments and possible V2X market demand outcomes. Click here for the report.
Offered only on the 2017 Cadillac CTS sedan in the U.S., DSRC (Dedicated Short-Range Communication) implementation has gone at a snail’s pace for a technology founded 20 years ago, the report says. Attention has shifted towards the cellular communication protocol as a means of promoting V2X more rapidly.
The DSRC V2X has its hurdles including the need for a new widespread infrastructure to be put in place and the limited adoption of DSRC in other automotive wireless applications such as ETC (Electronic Toll Collection).
Conversely, C-V2X can:
- leverage beacons already in place by the mobile industry and enables consumers immediate access to less safety-critical V2N (Vehicle-to-Network) and V2I (Vehicle-to-Infrastructure) applications
- using the PC5 interface link to the 5.9 GHz band to enable safety critical Non-Line-Of-Sight (NLOS) V2V (Vehicle-to-Vehicle) applications without adding data cost to consumers.
“This,” said Kevin Mak, Senior Analyst at the Automotive Practice of Strategy Analytics, “will enable a faster route to V2X than otherwise with DSRC.”
While the C-V2X ecosystem continues to expand, most recently with the release of the Qualcomm 9150 chipset platform, the report findings highlight significant ongoing contention between proponents of the two V2X solutions.
