In as much as the PowerPage focuses on mobile technologies, sometimes your desktop needs an upgrade or two.

According to Macworld, peripherals maker Sonnet Technologies has announced the availability of its Aria Extreme N 802.11n PCI card.

The card, which installs into a desktop Mac's PCI or PCI X slot, functions at up to 2.5 times the speed of an 802.11g card, supports multiple concurrent data stream transmissions and supports the WEP, WPA, AES and TKIP security protocols and is functional with Apple's AirPort hubs and base stations as well as other wireless hubs.

For users looking to upgrade their machines, the unit works in the Power Mac G4, Power Mac G5 and Mac Pro computers.

The card requires Mac OS X 10.4 or later to install and run.

If you've heard anything about the Aria card or have an 802.11n PCI card of choice, let us know in the comments or forums.
