Abstract

Currently, there are not enough Wi-Fi devices operating around U-NII-4 Channels 180 to 184 to understand the impact to Connected Vehicle (CV) applications. Therefore, further research is needed to deploy a density of real-world devices in the field to understand the impact of: Co-channel interference (within the 5.9GHz Safety Band), Adjacent channel interference (above and below the 5.9GHz Safety Band). Studies to date do not consider a saturation of real-world interference devices in the unlicensed Wi-Fi bands below and above the 5.9GHz Intelligent Transportation Systems (ITS) safety band. This is due to an unavailability of consumer Wi-Fi devices in the lower 40MHz of the previous 5.9GHz Dedicated Short Range Communications (DSRC) spectrum, and a low penetration of consumer Wi-Fi devices in the new Wi-Fi 6E spectrum. The objective of this project is to assess the resiliency of CV applications to interference by reporting real-world CV performance and develop methods for detecting and mitigating interference with GDOT deployed CV devices.
