Apple somewhat quietly updated its AirPort Extreme and Time Capsule products a few weeks ago. While the price points and storage capacities for Time Capsule remain the same, each product is now twice as robust–they have dual antennas and dual radios to accommodate discrete, simultaneous connections on the 802.11a/b/g and 802.11n frequencies.
This means that you can use your 802.11a/b/g device, such as iPod touch or iPhone, on the same network as Apple TV or modern Macs using the long-range and screaming fast 802.11n frequency—all without slowing the entire network to the speed of its slowest member.
It is true that adding an 802.11b device to an otherwise entirely 801.11n network will slow the whole lot down the 802.11b speeds. The beauty of these new base stations and time capsules is that the two frequencies can coexist as one cohesive network, with all devices participating at their maximum possible speed.
The new AirPort Extreme has been a godsend in our busy South Burlington flagship store. With forty or more devices connected at all times, with at least a handful of them not running at 802.11n, there was untapped potential for a faster network. Adding the new AirPort Extreme to the mix was an immediate and zero-configuration update, as the configuration file from the last generation model was used to deploy almost instantaneously.
