On its web site Apple has created a new section dedicated to the improved iTunes U service that was updated during its education-related media event. The new resources contain plenty of information for educators about how to use new digital features available in iTunes U.

Specifically, resources include training courses on iTunes U Course Manager and iTunes U Public Site Manager, as well as different guides on how to publish on iTunes U. Students and educators can also learn about using various types of educational content such as video clips, interactive presentations, audio recordings and more.

AppleInsider claims that Apple is expected to adopt and start supporting the new faster 802.11ac Wi-Fi specification into products this year.

The new 802.11ac standard achieves much faster wireless networking speeds than the existing 802.11n specification (in use on the latest Mac, AirPort and iOS devices) by using 2 to 4 times the frequency bandwidth (from 80 to 160MHz), more efficient data transfers through sophisticated modulation, and more antennas (up to 8; existing standards support up to 4, while Apple's Macs currently use up to 3).

This "Gigabit WiFi" offers speeds 3 times as fast as existing 802.11n wireless networks can with speeds of over 1 Gigabit per second.
