Metageek’s Chanalyzer 3.0 software for their $399 Wi-Spy 2.4x spectrum analyzer in a USB dongle adds signatures in a sidebar: patterns that let you match what you’re seeing in the graph to common interferers like microwave ovens and cordless phones. You can upload snapshots to get input from other users, or add to their Signatures Library. The Windows-only tool also provides greater control over recording, annotating, playing back, and slicing data. This software doesn’t work with their original Wi-Spy model (now dubbed “v1”), which continues to be sold and supported.
BelAir cited as revenue market leader worldwide for wireless mesh: This doesn’t surprise me. BelAir is the name I’m consistently hearing associated with most of the large-scale muni projects, such as Minneapolis and Toronto, which skews revenue up because so many nodes are needed for these projects. Can anyone tell me if Tropos, SkyPilot, or Strix has any large-scale metro projects that are being deployed? Or have three companies refocused their efforts? The revenue estimates for node shipments, by the way, come from Dell’Oro Group, a firm that’s been tracking the wireless industry for many years.
Intel modifies shrinkwrapped hardware to span 60 miles with standard Wi-Fi: It’s not a great trick to set up antennas and receive Wi-Fi signals dozens of miles away. The hard part is keeping a consistent link over time and dealing with latency and environmental factors. Intel says they’ve got a device that they’ll sell initially in India at what should be below $500 per node (although a pair is required for links). They expect most links will span about 30 miles, with one node on the edge of a city. An Intel manager says in this Technology Review article, “If you take standard Wi-Fi and focus, you can’t get past a few kilometers.” That is to laugh, as I imagine all you community networkers are now doing reading these words. It’s relatively easy to run Wi-Fi that far; you just have to know what parameters to tune. In fact, they’re not using Wi-Fi, but a protocol that’s Wi-Fi like, which employs a form of half-duplex TDMA (time division multiple access).
