POE vs Wireless Synchronized Clocks: What Global Aviation Teams Need to Know

Apr 22, 2025

Following our recent article on why synchronized clocks are essential for AOG desks, several colleagues in aviation reached out with a very practical question:

"Are synchronized clocks with multiple time zones available in both wireless and POE models?"

📡 Wireless vs. POE: What's the Difference?

In North America, wireless synchronized clocks are a popular choice because of their quick setup and minimal wiring requirements. They receive time updates over a wireless transmitter and are ideal for schools, small facilities, and aviation offices with limited IT infrastructure.

However, for aviation operations outside North America or in large-scale, mission-critical environments, the better option is POE (Power over Ethernet) synchronized clocks.

🌍 Why POE Clocks Are Better for Global Aviation Support

POE clocks offer more advanced functionality, including:

  • ✔️ Global compatibility — Works in any region with a network switch
  • ✔️ Real-time NTP synchronization over Ethernet
  • ✔️ Multi-time-zone display support (e.g., UTC / Zulu / Local / PST)
  • ✔️ Reduced maintenance — No batteries or wireless transmitters

If you need to display multiple time zones across your AOG desks, parts warehouses, or dispatch centers, POE is currently the only supported solution for multi-time-zone synchronized displays.

💬 A Personal Note

One of my long-time aviation colleagues asked this exact question recently, which prompted this post. It’s always great to hear from industry peers, and these kinds of operational questions show how much precision still matters in modern aviation support.
