WiFi detectors roundup
Handtops.com has roundup of five different WiFi detectors, SmartID's WiFi Detector WFS-1, PCTEL's WiFi Seeker, the new Kensington WiFi Finder Plus, Hawking Technologies' WiFi Locator HWL1, and the supposedly vaporous Digital Hotspotter HS10 from Canary Wireless. They'll definitely save you from having to boot up your lappy just to see whether there's WiFi about, but that's about the only thing these five have in common. Turns out there's a lot of variation in detection strength, range, form-factor, and the ability to filter out non-WiFi signals (the Digital Hotspotter's the only one that can display SSIDs and whether a network is closed or open), and there was no clear winner among the five detectors.
