Collaboration Bureau participates in ISPCS 2026
One more year the White Rabbit Collaboration Bureau participate in the International IEEE Symposium on Precision Clock Synchronization for Measurement, Control, & Communication. The first two days are the plugfest, where companies test their different equipment together. A whole section was dedicated to White Rabbit and High Accuracy. The next two days are full of

The 15th White Rabbit Workshop takes place at CERN
Two days of talks and networking bringing together the White Rabbit community. This year we heard, for example about the use of White Rabbit at the European Commission’s Joint Research Centre or the Amsterdam Internet Exchange. We learned more about the temperature dependance of White Rabbit or how it can be cryptographically secured. There is

International Timing and Sync Forum 2025
The International Timing & Sync Forum (ITSF) is the world’s largest specialist time and synchronisation conference showcasing the latest time and synchronisation solutions, advances and challenges across sectors. Once again the White Rabbit Collaboration participated in the event. Many members of the of the Collaboration got together at ITSF in Prague, with different talks, posters

High Accuracy Synchronization for Distributed Massive MIMO using White Rabbit
Abstract Accurate synchronization is a crucial prerequisite for wireless communication systems and in particular for spatially distributed massive multiple-input multiple-output (MIMO) systems which is also used in the upcoming 5G mobile communication standard. Many applications based on MIMO transmission, such as communication systems or beamforming methods, require synchronization accuracy in the low sub-nanosecond range which

White Rabbit Applications and Enhancements
Abstract This article provides a non-exhaustive overview of applications and enhancements to the White Rabbit (WR) extension of the IEEE 1588 Precision Time Protocol (PTP). Initially developed to serve accelerators at the European Or-ganization for Nuclear Research (CERN), WR has become a widely-used synchronization solution in scientific installations. This article classifies WR applications into five

White Rabbit Absolute Calibration
Abstract White Rabbit (WR) is a widely used implementation to create high accuracy time dissemination networks. Onsite network calibration can be avoided when using absolute calibrated components, which can be freely exchanged withoutrecalibration. Absolute calibration of high accuracy time dissemination network components enables independent developers and/or vendors to exchange their calibrated components while achieving absolute

Scalability Analysis of the White-Rabbit Technology for Cascade-Chain Networks
Abstract Due to an increase of timing requirements in many actual and future applications, improvements are needed in current synchronization protocols. New scenarios as the Internet of Things or the next generation of 5G Mobile telecommunication networks, where a large number of devices must be interconnected, will stand in need of a better synchronization accuracy

Reliability in a White Rabbit Network
Abstract White Rabbit (WR) is a time-deterministic, low-latency Ethernet-based network which enables transparent, subns accuracy timing distribution. It is being developed to replace the General Machine Timing (GMT) system currently used at CERN and will become the foundation for the control system of the Facility for Antiproton and Ion Research (FAIR) at GSI. High reliability

White Rabbit: a PTP Application for Robust Sub-nanosecond Synchronization
Abstract This article describes time distribution in a White Rabbit Network. We start by presenting a short overview of the White Rabbit project explaining its requirements to highlight the importance of the timing aspects of the system. We then introduce the technologies used to achieve high clock accuracy, stability and resilience in all the components

White Rabbit: Sub-Nanosecond Timing Distribution over Ethernet
Abstract White Rabbit (WR) is the project name for a ambiguous project that uses Ethernet as both, deterministic (synchronous) data transfer and timing network. The presented design aims for a general purpose, fieldbus like transmission system, which provides deterministic data and timing to approximately 1000 timing stations. The main advantage over conventional systems is the
