FCC passes auto safety spectrum rules
C-V2X will use existing cellular networks to send messages from vehicle to vehicle, vehicle to infrastructure, vehicle to cyclists, or vehicle to pedestrians to warn of each other's presence for safety purposes. It could cross-alert for hazardous road conditions, including speeding cars, weather, or traffic congestion.
C-V2X communication requires _very_ precise timing so that transmitting devices can find and use their transmission time slot. We rely on GPS time for this.
For our V2X node (https://www.zero-iee.com/assets/products/pdfs/V2XNode_Product_Description.pdf), we are therefore trying out various GPS modules that provide us with the necessary 1PPS signal. This is not the case for all modules.
We are curious to see whether the AT6558R GPS chip proves itself and meets our requirements.
