Schaumburg, Illinois-based First International Digital, already famous for its popular irock!, Beamit, and MusiCase series of digital audio devices and iPod accessories, has just launched its WiFi Sentry (Model 240WS). WiFi Sentry allows users to find hotspots with one push of a button. The device locates both 802.11b and 802.11g networks within 300 feet in less than one-half second. Four bright LEDs indicate relative signal strength and direction. WiFi Sentry is small and light enough to be attached to a keychain. The device sells for $24.99. The company says that, unlike other wireless AP locators, WiFi Sentry is immune to false readings from devices such as cordless phones and microwave ovens.
