Other World Computing (OWC) today announced the availability of 802.11n WiFi Adapters that allows any Mac computer to upgrade to 802.11n wireless connectivity via USB, PCMCIA, or PCI card options. Priced from US$67.99, these new 802.11n WiFi Adapters offered by OWC also provide backwards compatibility for use on 802.11b and 802.11g networks. 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, says the company. 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 Mac OS X 10.3.x or later.
