Apple Updates AirPort Extreme And Time Capsule Networking Products
There are six total antennas, three for the 2.4GHz band and three for the 5GHz band. There's also a built-in firewall, three Gigabit Ethernet LAN ports, a USB 2.0 port (for printers and such), and a built-in power supply. It'll support beamforming and up to 50 users, and it'll handle any device that supports the 802.11a/b/g/n/ac specification.
If you'd prefer to turn your AirPort Extreme into a NAS, there's also a new Time Capsule; it's essentially the same exterior, but with a 2TB ($299) or 3TB ($399) hard drive within. All of this stuff starts shipping this week, too.
