Koingo Software has updated AirRadar, a Wi-Fi scanning and graphing tool for Mac OS X, to version 3.0.

New features are an improved graph, the ability to join enterprise networks, 802.11ac support, network card switching, 100% Apple-native WiFi frameworks, enhanced smart collections, "official" Keychain integration, streamlining of the interface and more.

Upgrades are free for buyers ordering AirRadar 2.x within the past 6six months. All previous customers wishing to use 3.x must use the upgrades form on the Koingo website (www.koingosw.com). This form will either automatically issue a free upgrade, or redirect to a shopping cart with the paid upgrade pricing. Paid upgrades are US$7 for customers outside of the free upgrades policy. For new users the cost is $9.95. A demo is available for download.
