WSA - LTE-V2X WSMP

Description:

This solution is used within the U.S.. It combines standards associated with WSA with those for V-X: LTE-V2X WSMP. The WSA standards include standards required to advertise ITS services to short-range wireless devices. The V-X: LTE-V2X WSMP standards include lower-layer standards that support connectionless, near constant, ultra-low latency vehicle-to-any communications using the WAVE Short Messaging Protocol (WSMP) over 3GPP C-V2X in the 5.9GHz spectrum.

Solution Issues Severity: 12

Solution Issues:

Default	Severity	Name	Type	Description
True	Medium	Overlap of standards	Overlap	Multiple standards have been developed to address this information and it is unclear which standard should be used to address this specific information flow.
True	Medium	Regulatory Permission Needed	Standardization Gap	Deployment of this standard requires regulatory approval, which is currently subject to significant delays.
True	Medium	Still under development	Standardization Gap	A draft of the standard has been developed by the working group, but it was still under development at the time this analysis was performed.
True	Medium	Uncertainty about trust revocation mechanism	Security Gap	The mechanisms used to prevent bad actors from sending authorized messages is unproven.
