22 Inside GNSS M A Y / J U N E 2 0 1 8 WSTS Timing and Sync Workshop Slated for San Jose T h e 2 7 t h A n n u a l Wo r k s h o p on Synchronizat ion and Tim- ing Systems (WSTS), sponsored by NIST and ATIS, will take place June 18-21, 2018 in San Jose, California. WSTS is a vendor-neutral technology workshop that addresses evolving sync requirements, as well as the roll-out of new sync systems and standards and their impact on industries and equip- ment manufacturers. e WSTS is managed by a Steering Committee composed of synchroniza- tion experts representing a cross section of users, manufacturers and profession- als associated with synchronization in a variety of industries. The Commit- tee sets the strategic priorities for the event and defines the main topics to be addressed each year. WS T S re pre s e nt s pre - e m i n e nt experts in synchronization for telecom and related applications. Many of these experts participate in various standards bodies including ATIS, ITU, IEEE and IETF. Accurate time synchronization is an essential driving force in the success of today's most commonly used technolo- gies. Telecom, finance, utilities, broad- cast, transportation, IoT, and defense are evolving with critical timing enablers in many of their systems. Telecom continues to require tighter "sync" particularly f o r t h e o p e r at i o n of mobile wireless systems. 5G, driven by the demands of significantly greater sp ectral ef f icienc y and the migration to small cells, is particu- larly sync-dependent. N e x t - g e n e r a t i o n E911 networks now have new, more strin- gent requirements for time synchronization. M a n y o t h e r industries are find- ing either the need or the attraction to precision timing and synchronization. In the finance industry, markets are coming under tighter restric- tions on time-stamp- ing of trades. e power industry needs accurate reliable time for managing the grid. Smart Transportation Systems will need a number of types of preci- sion timing to support a wide variety of systems and services. In the Internet of ings (IoT), many are forecasting an unprecedented growth of endpoints to the network that will require time- stamping in sensors and latency control. Defense systems require various kinds of timing to support actions and ser- vices in challenged environments. Also, greater awareness is developing of GPS and GNSS vulnerability to inten- tional and unintentional interference. Today's networks face challenges as they support both existing and emerg- ing services that have a variety of sync needs: time, frequency and phase syn- chronization. Add to the mix that new standards for time synchronization are being developed in the ATIS, ITU, IEEE, IETF and other standards bodies. "GPS is extremely reliable and accu- rate, and that's why our timing systems depend on it." says Marc Weiss, Founder and Chair of WSTS, "However, extreme reliability is not one hundred percent reliability. at's why GPS' effectiveness is also a problem and has led to blind trust. Most companies do not have back-ups for when the system goes down. Any form of failure can be cata- strophic." On June 22 there will be a co-located event — Assured Access to Accurate Time Workshop: A Comprehensive View of Timing Solutions and Interop- erability Issues. The goal of this workshop is two- fold: to come to a consensus on a set of attributes defining assuredness of time, as well as to provide a venue for coor- dination between user communities, government players and time providers.
