Accurate time synchronisation is essential to enable communications networks. The NIST-ATIS sponsored workshop highlights both evolving sync requirements and deployment strategies for new sync systems and standards and how these affect industries and equipment manufacturers. WSTS is managed by a Steering Committee comprising sync experts from a variety of industries and defines the main topics to be addressed each year. Together with its sister conference ITSF in Europe, WSTS represent a global alliance of pre-eminent experts associated with synchronisation in a wide variety of industries such as Telecom, Finance, Energy, Broadcast, IoT and Defence. Many of these experts act as steering group members for both conferences, as well as sit on various standards bodies including ITU, ATIS, IEEE and IETF.
