Other World Computing announced today the availability of 802.11n WiFi Adapters that promise to let any Macintosh computer upgrade to 802.11n wireless connectivity via USB, PCMCIA, or PCI card options.

With 802.11n, indoor ranges of up to 220 feet (outdoor up to 500 feet) and performance of up to 300Mbps are possible — or up to 5 times the range and performance of 802.11g. The 802.11n WiFi Adapters are fully tested and supported by OWC to work with any G3, G4, G5, or Intel processor-based Mac or PC with an available PCI, USB 2.0, or PCMCIA Card slot running Apple OS X 10.3.x or later or Windows 2000/XP and later.The new 802.11n WiFi Adapters offered by OWC also provide backwards compatibility for use on 802.11b and 802.11g networks.

Apple first introduced support for the 802.11n wireless protocol in January 2007. Until recently, the only Macs able to utilize 802.11n were the Mac Pro Quad/8-Way Towers or MacBook/MacBook Pro/iMac models with a Core 2 Duo processor.

Priced from $67.99, the OWC 802.11n WiFi Adapters are supported by OWC to work with any G3, G4, G5, or Intel processor-based Mac or PC with an available PCI, USB 2.0, or PCMCIA Card slot running Apple OS X 10.3.x or later or Windows 2000/XP and later.
