AirPort Radar Dashboard Widget

AirPort Radar is a free and convenient tool for quickly scanning the area
for AirPort and other wireless networks. It will work with AirPort cards,
MacWireless 11g PC Cards, and 11g PCI cards. Mac OS X 10.4 Tiger is required.
Signal Strength at a Glance - Visual signal meters tell you the strength of
the AirPort signal for an easy-to-read radar screen.
Sortable Network List - Click on a category to sort the list of networks by
that category. Click on the radio waves symbol to sort by signal strength.
Connect to Open Networks - By simply clicking on the name you can connect
to any network that is not password protected.
Remember Lost Networks - When a network falls "below radar" it won't
disappear from your radar screen right away. This is particularly useful
when a network is right on the threshold - with AirPort Radar it won't jump
on and off the radar screen, it will just turn grey temporarily while it is
too weak to connect to.

You can choose how many scans a lost network stays on-screen with the "Scan
Memory" setting on the back side of the widget.
Auto-Resizing for Various List Lengths - The AirPort Radar widget will
automatically resize itself to accomodate longer or shorter lists of
wireless networks.
