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

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

  • 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
