Thinkertons.com today announced the release of AirStatz 1.2.1u, a free WiFi/Airport tool For Mac OS X 10.4 or later. AirStatz is a fast, easy and highly graphical WiFi (AirPort) signal display. The primary display is a dynamic pie-chart showing the ratio between signal (green) and noise (red). This display updates at 8-10 times per second on a 800Mhz G4 iBook or better, which is 20x faster (to be charitable) than the Apple Airport menu signal-strength display. AirStatz also provides two drawers with constantly updating technical information — one on the current connection, and the other on all available wireless access points.
