WiFi Detector Reviews

This is a good review of several WiFi "detectors" that are currently on the market. I've used the Smart ID WFS-1 and it usually works pretty well. The downside to most of these products is that while they can tell you if a wireless network is available, they can't tell you what kind ("g" or "b"), if it is an open network, or any other configuration information. They can also sometimes be fooled by microwave ovens, some cordless phones, and Bluetooth devices, but as most of the products mentioned are fairly low cost it is a useful tool to keep in a travel bag.
