Mesh and Mobility – Marriage Made in Wireless Heaven?

Earlier in November Firetide announced Seoul Subway video surveillance system delivering real-time streaming to and from trains moving at 50 mph [pictures]. This project is kind of a big deal. Apart from the facts that:

  • this is the first such deployment underground;
  • the system delivers 20 Mbps of capacity for high-quality, 30-frames-per-second video;
  • initial phase of the project is 1,000 nodes
  • it’s deployed in extremely harsh conditions with reflective metal, vibration and dust;

the key to the deployment is Firetide’s mesh infrastructure mobility: the ability to maintain real-time connections between fixed and mobile mesh nodes moving at high speeds –  without dropping packets and introducing latency or jitter

“Mobility” is a frequent requirement we hear about from our customers, and by mobility we mean hard-core infrastructure mobility, not “client mobility” as Wi-Fi access point vendors define it: between APs and smart phones, laptops, etc. Wi-Fi access architecture is enough to support non-critical low-bandwidth data, but for challenging environments and to support real-time video streaming or VoIP, only mesh will fit the bill.

Similarly, you cannot truly implement mobility with point-to-multipoint equipment, because of the central ‘command-and-control’ architecture, which does not allow for roaming. Mesh, with its distributed architecture and intelligence can support mobility within the mesh, and even roaming across multiple meshes.

Mobile real-time video is the wave of the future – for city-wide public safety, industrial sites, campus environments, mining and transportation. (Tip: you will need Firetide Mobility Controller, if your network design involves roaming between meshes).

While we are setting up our super-snazzy corporate blog for Firetide, I will be posting articles and observations on wireless mesh, Wi-Fi, video surveillance, ITS and our solutions for municipalities, industrial, government and transportation customers here.
