Flight Proven: In-Flight Validation — December 2025
Airbus A350-900 (9V-SNA) | Panasonic Avionics IFE Infrastructure | Major Southeast Asian Carrier
Context
In December 2025, 5n Networks conducted a live in-flight validation of its patented mesh technology aboard an Airbus A350-900 (registration 9V-SNA) operated by a major Southeast Asian carrier. The aircraft was equipped with Panasonic Avionics IFE infrastructure with approximately 5 Mbps of available satellite bandwidth — representative of real-world conditions on long-haul routes.
The Challenge
Traditional unicast delivery requires a dedicated stream per passenger. For a full A350 cabin of approximately 300 passengers watching live TV, this would demand roughly 1,500 Mbps — more than 300x the available satellite capacity. This is why live TV to every seat has been considered technically infeasible on commercial aircraft. Airlines either limit streaming to a handful of users, offer only cached/on-demand content, or accept degraded quality for all.
Results
Live streaming bandwidth consumption measured during flight:
| Simultaneous Viewers | Total Bandwidth Consumed | Bandwidth per Viewer | Reduction vs Unicast |
|---|---|---|---|
| 1 | 1.10 Mbps | 1.10 Mbps | Baseline |
| 5 | 1.28 Mbps | 0.26 Mbps | 77% |
| 50 | 1.47 Mbps | 0.03 Mbps | 97% |

All figures confirmed independently by aircraft operator and IFE infrastructure provider.
What This Means
The near-flat bandwidth curve — from 1.10 Mbps at 1 viewer to 1.47 Mbps at 50 viewers — demonstrates that 5n Networks' mesh architecture fundamentally changes the economics of in-flight live streaming. Adding viewers does not proportionally increase bandwidth demand. This means airlines and IFC providers can deliver live TV to every seat on an aircraft within existing satellite capacity, with no additional hardware, no STC certification, and deployment measured in days rather than months.
The December 2025 validation achieved TRL-9 — the highest technology readiness level — confirming that 5n Networks' technology is operational in real-world conditions and ready for commercial deployment.
"The results speak for themselves — 50 passengers streaming live content on bandwidth that would normally serve a single user. This isn't an incremental improvement. It's a structural change in what's possible on an aircraft."
