V2XBridge: Bridging DSRC, C-V2X, Satellite, and Cloud Telematics

V2XBridge provides dual-stack bridging, multi-radio coexistence, and multi-access translation between IEEE 802.11p/bd DSRC, 3GPP C-V2X, and Non-Terrestrial Network (NTN) satellite links.

Resolving the Global Fragmentation of Connected Vehicle Frequencies

Global transport corridors traverse jurisdictions mandating different physical layers (DSRC in parts of Europe and Japan, C-V2X in China and the US). V2XBridge delivers dual-active abstraction layers ensuring universal safety interoperability.

Core Engineering Areas

• DSRC & C-V2X Coexistence — RF front-end filtering and dynamic time-sharing between IEEE 802.11p/bd and 3GPP cellular sidelink.
• Protocol Translation & Mapping — Translating American SAE J2735 messages into European ETSI ITS-G5 frames with zero semantic data loss.
• Satellite NTN to V2X Bridging — Integrating 3GPP Release 17 NTN satellite communications to bridge dead zones outside terrestrial RSU range.
