NanoPing uses three Wi-Fi networks at once to stream live video with zero late packets
Multi-connectivity for real-time streaming over Wi-Fi
In a 30-meter lab walk, a laptop streamed 7 Mbps live video over three Wi-Fi networks simultaneously. While each network alone would have caused stutters, NanoPing delivered every packet within 100 ms, with no frames late or lost. The system dynamically steered traffic to the strongest network and used the others to repair losses, achieving 100% on-time delivery.
In none of the 600 tenths of a second were all three too slow at once.

Hey mortenvp, ex-enterprise network admin's thoughts & questions:
- The 3 interfaces detail is a bit buried. For a second I thought you were somehow changing the adapter channel and association quickly enough on a single adapter.
- What approach are you taking to still present the client as a single IP source during the video call? (partly curiosity, largely curious how that interacts with using the network).
- Why are the comparisons to a single pinned AP only instead of normal roaming across them (preferably with KVR)? It makes me particularly suspicious of the results would be better, especially since pinning to AP B the entire time was already itself 0.17% off perfect.
- Do you have any comparisons with newer MLO setups to say "gives you x% of MLO without having to wait for infrastructure to catch up" or anything?

Unifi had this on their old access points (Multi-AP coordination outside of the spec)
Now we have 802.11r fast roaming and with 802.11bn (WiFi-8) it will be basically instant, because that standard adds SMD (Seamless Roaming Domain). The APs will talk to each other and share the client connection state.

WiFi is a real pain in many situations! This can actually help!
