- 17. 2023 © ADTRAN, INC. 17 GREAT IDEAS Paths to resilient, assured PNT SOLUTIONS • ePRTC • Low Earth Orbit • Terrestrial • Timing over Fiber • Local RF Relay • eLORAN • Timing as a Service over ETH • Timing Backup as a Service ADVANTAGES ✓ Zero Trust Concept ✓ Risk Aversion ✓ Growing Markets ✓ availability DISADVANTEGES ✓ Some are fee-based ✓ Any RF can be disrupted/jammed ✓ Fibers can be cut/damaged (routinely) ✓ Diversity requires 2x everything ✓ Including diverse routes Capital vs expense ❖ Capital-intensive businesses prefer one-time payment ❖ Expense budgets are shrinking ❖ Avoid recurring, incurred expenses
- 18. 2023 © ADTRAN, INC. 18 WRAPPING IT UP Timing/sync trends • Packet-only vs all-in-one clocks • Packet-only- 5G • All others all-in-one • ePRTC now standard requirement • No longer a “hard sell” • Is a capital item • Optical cesium the new norm • New RFQ’s demand optical cesium- no mags • Why? • Partnerships a must • Universal management • Health of legacy and new clocks • Self- and port-probing • Hybrid networks the norm • 5 years • Manage sync during transitions
