V2XStack: Complete Protocol Stack Architecture for Connected Vehicles

V2XStack provides complete, modular, and standards-compliant protocol implementations covering GeoNetworking, BTP, ASN.1 encoding, and safety application services.

A Production-Ready Communications Stack from Physical Drivers to Applications

Deploying V2X requires implementing dozens of interconnected RFCs, 3GPP specifications, and SAE/ETSI standards. V2XStack provides an open, highly optimized modular stack that integrates seamlessly with automotive RTOS and Linux.

Core Engineering Areas

• GeoNetworking & BTP — Routing messages to geographic destination areas without IP address configuration.
• Facilities Layer Architecture — Maintaining high-frequency vehicle registries and coordinating transmission slot budgets.
• ASN.1 UPER Compression — Bit-level compression minimizing radio airtime for 100-byte CAM safety payloads.
