Wi-Spy spies on Wi-Fi

摘要

While we continue to investigate our problem with deferred procedure calls (see the recent Gearhead at) — a problem that seems to have mysteriously vanished again — we wanted to bring to your attention a tool that, if you are doing wireless stuff, you are going to want. The tool is Wi-Spy 2.4x from the wonderfully named MetaGeek. The Wi-Spy is a USB (1.1 or 2) spectrum analyzer for the radio frequency range from 2400MHz to 2483.5MHz with a resolution of 328KHz. It can detect signals in the range -110dBm to -6.5dBm with an amplitude resolution of 0.5dBm and has a sweep time of 165 millisec.
