NanoPing enables real-time video streaming over multiple Wi-Fi networks simultaneously
Key points
- NanoPing uses three Wi-Fi networks simultaneously for live video.
- It ensures all packets arrive within 100 ms latency.
- Individual networks failed to maintain real-time video.
- The system dynamically switches to available strong networks.
Multi-connectivity for Live Video
A new system called NanoPing has been demonstrated to enable real-time live video streaming over Wi-Fi by utilizing multiple networks simultaneously. This method addresses the challenge of maintaining consistent video quality in environments where a single Wi-Fi access point cannot provide continuous coverage or sufficient bandwidth.
Addressing Latency and Packet Loss
During a test involving a laptop moving through a 30-meter lab, NanoPing successfully delivered all video packets within a 100 ms latency target. In contrast, individual Wi-Fi networks in the same environment experienced significant packet delays, with one network requiring 941 ms for 99% of packets, leading to potential video stuttering or loss. NanoPing achieved this by dynamically routing video traffic through the strongest available network at any given moment.
Dynamic Network Utilization
The system continuously monitors the signal strength of each connected network. As the laptop moved and signal strengths varied, NanoPing allocated video traffic to the networks performing best. The demonstration showed that at no point were all three networks simultaneously too slow, allowing NanoPing to maintain uninterrupted video flow by leveraging the combined capacity and reliability of multiple connections.

Reporting from
Researchers demonstrated NanoPing, a system that uses multiple Wi-Fi networks concurrently to maintain real-time video streaming. This approach prevents video stuttering and packet loss in environments where single Wi-Fi access points are insufficient, by dynamically switching between available networks.
