OpenSTX Foundation

What OpenSTX Foundation does

OpenSTX Foundation is a non-profit, community-driven standards organization hosted under the Linux Foundation, dedicated to standardizing Synchronous Transmission (STX) technology for wireless networks. STX is a technique in which multiple devices transmit simultaneously to achieve time synchronization, enhanced robustness, low latency, and energy efficiency in multi-hop wireless networks. The foundation develops an open, vendor-neutral specification for STX-based protocols along with reference implementations (including OSF and OSFv6) and example applications. The architecture is modular, with clean interfaces between the core STX engine, radio abstraction layers supporting both narrowband and ultra-wideband radios, and higher-layer integrations including IPv6 (OSFv6) and 6TiSCH++ with concurrent Bluetooth 5 transmissions.

The foundation is governed by a Steering Committee comprising representatives from member organizations, with technical work organized across four active working groups: WG1 Integration, WG2 Protocols, WG3 Radio Abstraction Layer, and WG4 Security/Localization. It draws membership from leading research institutions (Imperial College London, TU Darmstadt, University of Trento, Graz University of Technology, imec) and industrial firms (Technology Innovation Institute, SKF, RedNodeLabs, Fly4Future, Unikie), led by recognized academic and industry experts in low-power wireless networking and IoT. Its target use cases include industrial IoT, cyber-physical systems, smart city infrastructure, asset tracking, environmental sensing, disaster response networks, and aerospace/UAV communications.

The foundation operates on a non-commercial membership model: Contributor membership is free and requires only active community engagement, while Steering Committee memberships are evaluated case-by-case. The foundation states it is fully funded through 2027 via the Linux Foundation, and it generates no commercial revenue. Distribution is entirely open-source, with specifications, reference implementations, and tools made publicly available via GitHub, supported by academic publications, working group activity, and participation in industry conferences such as EWSN.

Core offering

OpenSTX Foundation develops an open, vendor-neutral specification for Synchronous Transmission (STX) wireless networking protocols, enabling multiple devices to transmit simultaneously for time synchronization, enhanced robustness, and network-wide mobility in low-power multi-hop networks. It delivers reference implementations and example applications (including OSF and OSFv6) across narrowband and ultra-wideband radio platforms under Linux Foundation governance.

Product overview

The OpenSTX Foundation offers a single unified specification portfolio centered on the OpenSTX Specification for Synchronous Transmissions in wireless networks. The specification defines STX-based networking protocols enabling devices to transmit simultaneously for time synchronization, enhanced robustness, and network-wide mobility. The OpenSTX Reference Implementations and Tools (including OSF and OSFv6) provide open-source implementations of the specification across multiple physical layers. The foundation's modular architecture includes clean interfaces between the core STX engine, radio abstraction layers (for narrowband and UWB), and higher-layer integrations like IPv6. The offering spans four working groups covering Integration, Protocols, Radio Abstraction Layer (RAL), and Security/Localization.
