Apple has updated their AirPort Extreme Base Station and Time Capsule offerings. A few of the new features That includes:
Simultaneous dual-band support – Operates simultaneously on both 5 GHz (802.11n) and 2.4 GHz (802.11b/g) frequencies to allow all wireless products to connect on the best available band. On previous models, users wishing to permit 802.11b/g devices such as many older Macs or the iPhone or iPod touch to connect to their access point were required to run in “mixed mode” at 2.4 GHz, negating some of peformance benefits of 802.11n-enabled devices running on 5 GHz networks.
Guest networking – Creates a secondary network to allow family and visitors to connect to the Internet, while keeping the primary network with attached printers, drives, and other devices secured. The secondary network can be configured with a different password from the primary network or can have no password at all.
Access files on a networked drive from anywhere – Allows MobileMe subscribers to register their AirPort Extreme Base Station or Time Capsule with their MobileMe account, providing them access to their files from anywhere via the Internet. Drives will appear in the Finder sidebar like any other attached drive, acting just like a personal file server with remote access.
For those who already own Airport Extreme or Time Capsule units and who have a MobileMe account, the firmware upgrade that comes with software release 7.4.1 would upgrade the units to include the third feature: the universal MobileMe / “Back-to-my-Mac” access. After the upgrade, go to the device in Airport Utilit –> Advanced –> MobileMe to activate the Time Capsule storage drive or the USB drive attached to the Airpot Extreme units.
Very cool feature!
but it isn’t available to users of older Airport Extreme or Airport Express units :-/
The other two features would require dedicated hardware facilities and as such are not available to any previous units.
