Abstract (300 words maximum)
As technologies evolve and new devices are introduced, the demand for fast and reliable vehicle-to-everything (V2X) communication increases. As this demand increases, the interference level in the 5.9GHz Dedicated Short Range Communications (DSRC) band will inevitably increase. And thus, the task of somehow minimizing this interference becomes increasingly important as time passes. This report investigates the effects of increasing the guard band size of the lower 5.9 GHz DSRC band on the adjacent channel interference from Unlicensed National Information Infrastructure 4 band (U-NII-4) devices and to try and see if there is a significant decrease in the interference level. The changes in the interference levels are being measured through packet reception rate (PRR) in vehicle-to-infrastructure (V2I) communication and infrastructure-to-vehicle communication (I2V). Experimental observations in lab using 25 low-cost U-NII-4 devices have shown a significant increase in PRR when shifting the central frequency of these devices for both V2I and I2V communications.

Increasing Guard Band Size to Decrease Interference in V2X Communication
As technologies evolve and new devices are introduced, the demand for fast and reliable vehicle-to-everything (V2X) communication increases. As this demand increases, the interference level in the 5.9GHz Dedicated Short Range Communications (DSRC) band will inevitably increase. And thus, the task of somehow minimizing this interference becomes increasingly important as time passes. This report investigates the effects of increasing the guard band size of the lower 5.9 GHz DSRC band on the adjacent channel interference from Unlicensed National Information Infrastructure 4 band (U-NII-4) devices and to try and see if there is a significant decrease in the interference level. The changes in the interference levels are being measured through packet reception rate (PRR) in vehicle-to-infrastructure (V2I) communication and infrastructure-to-vehicle communication (I2V). Experimental observations in lab using 25 low-cost U-NII-4 devices have shown a significant increase in PRR when shifting the central frequency of these devices for both V2I and I2V communications.
