Metageek releases 2.4/5 GHz spectrum analyzer: The $799 Wi-Spy DBx, designed for network engineers, started shipping a few days ago. Metageek has long offered a 2.4 GHz analyzer ($399); this devices adds the 5 GHz band. I had a brief demo from a beta tester a few days ago, and it's rather slick. This might be a terrific tool for those building large-scale networks, trying to determine interferer sources. As with the previous Wi-Spy tools, graphical analysis software is included that allows the import and creation of profile to characterize common patterns, like cordless phones or microwave ovens.

Auckland fires up Wi-Fi service: Service was turned in preparation for the America's Cup regatta starting later this month. It's not free: NZ$3 (US$1.60) per hour, NZ$6.50 (US$3.50) per day, and NZ$30 (US$16) per month. But it's considered pretty affordable within the context of the local economy. Service is in zones rather than seamlessly across the town.

WeFi offers hotspot directory: I'm not impressed. I checked out Seattle in their database of 14 million networks and growing, and found a handful of networks across the city, even looking at both close, open, and authentication-required networks. Pretty paltry. There have been many attempts to have user-generated hotspot directories over the years. They have all faltered or failed because there's a lot of hard work in not just finding and cataloguing locations, but cleaning the data and updating it correctly over time. My usual disclosure: I own a very very small number of shares in JiWire, which built one of the first hotspot directories and still operates it. But, despite that disclosure, JiWire's the only directory that's usable; I've tried them all, and I try each new one, too.
