Improving Communications Network Timing for Resilience
Explore how to enhance communications network resilience through backup timing solutions independent of GPS signals. Working Group 4B focuses on defining the problem, identifying backup solution characteristics, and evaluating technologies for precise timing. With a diverse group of experts, the group aims to submit draft reports in mid-2016 and final reports by early 2017, following a structured schedule of bi-weekly calls.

Working Group 4B: Network Timing Single Source Risk Reduction Status Update September 21, 2015 Jennifer A. Manner, Chair
WG4B Objectives Working Group Description: Synchronized network timing (time of day, standard time intervals, standard frequencies, and corrections) is a crucial element of a communications network management. However, given the high dependence of the communications sector on GNSS, the Commission is interested in identifying ways to increase the resilience of communications networks by exploring complementary or backup solutions that could be employed to offer similar time precision as GNSS in the event that GNSS signals are lost. These solutions need to be independent of GNSS to reduce risk and solutions need to be employed across the sector. Deliverables: The Working Group will make recommendations on acquiring and implementing back-up precision timing solutions that are independent of GPS. Define the problem, including vulnerability of the GNSS systems, and what is the impact of the result of any failure Define required characteristics for back-up solution Identify what technologies are possible to solve the problem and the pros and cons of each 2
