The Call for Papers for the 2017 Workshop on Synchronization and Timing Systems:
The (R)evolution in the Need for Time, deadline has been extended until Friday, November 11, 2016.
Please contact Lois Rude at firstname.lastname@example.org with any questions.
Industries including Finance, Broadcast, Transport, Utilities, IoT, Defense and equipment manufacturers use time to achieve accurate control in time and space. The need for time encompasses many forms, including synchronization among end points to time stamp events or to coordinate actions such as alignment of audio and video in multimedia presentations. For example, the finance industry has new requirements for time stamp accuracy against UTC – 100 microseconds in Europe and 50 milliseconds in the U.S., the power industry needs about 1 microsecond accuracy against UTC for synchrophaser control, and smart transportation needs 1 ms synchronization among nodes for V2X coordination. Some needs are for deterministic latency to ensure proper timing in industrial control, in financial trade orders, or other systems. Which applications depend upon time today? How are their timing accuracy requirements becoming more acute? Are current timing systems reliable and secure enough? What solutions are needed today to meet the increase in demand for time, both now and into the future?
Timing in telecom has a past and present, and the future is speeding forward. Legacy systems remain and need traditional timing (frequency) to support them. Current challenges include services to support wireless applications, such as backhaul, next generation fronthaul, cloud-based RAN (C-RAN), and carrier aggregation, all of which require both frequency and phase/time alignment to an increasing level of precision. 5G is seen as the future, with many different visions for requirements. How can telecom manage timing systems to maintain legacy systems while merging into present and future systems? Which telecom applications are dependent upon time today, and how will their time precision requirements become more acute?
Many industries have unique Standards or profiles for their own timing needs. Can individual industries maintain their unique requirements using profiles and/or Standards from other industries? What are the emerging standardization needs? How can industries collaborate to create Standards relevant to different applications?
UTC is generally the international time standard, but what is actually needed in specific systems? Global delivery of time is mostly via Global Navigation Satellite Systems (GNSS), but is this the best and most secure method? Can telecom networks or alternative PNT solutions play a role? What is the role of Service Level Agreements (SLAs)? What are time use cases across various markets and applications (e.g Indoor vs. Outdoor, wired vs. wireless), and how are the requirements achieved? What components are being delivered or developed in systems to deliver time? What are the cost challenges of delivering precise UTC traceable time? For example, it can cost many times the timing element hardware cost to install and host GNSS antennas on a roof.
There are barriers and vulnerabilities to existing infrastructure for precise time or phase delivery. Transport of time over any media will not achieve 100% availability. How do we protect applications whose requirements approach 100% time availability? What is the impact on cost? How do we deal with irregularities such as GNSS Jamming, Interference, Space Weather, System Failure and Spoofing or PTP (IEEE 1588) packet delay variation and network asymmetries when distributing UTC traceable timing. To what extent do we need to review existing sync network architectures? What are the challenges to offering Time as a Service, given existing infrastructure, scales of size and accuracy, and the need for SLAs and Standards conformity? How do emerging government regulations and mandates play a role? What other cost-effective time dissemination solutions are there that do not suffer the same vulnerabilities as GNSS and PTP?
What technology development, both near-term and longer-term, will improve the delivery and accuracy of time? Will new innovative components, such as processor-integrated precise time generation, reduce the need to distribute these? How will processors have access to time with requisite accuracy? What are improvements or alternatives to IEEE1588? How can measurements such as 1588 data be available externally? What will be the role of higher performance oscillators? Will new oscillator technologies bend the cost-performance-resiliency curve?
