Nortel and Cisco have decided to use some of their marketing budget for something really useful for engineers, namely to open up the IEEE standards 802 library for free public access. These include the famous Ethernet (802.1,2,3), Wifi (802.11) and WiMAX (802.16) standards. A great help for all doing research in this area. Little downside: Only approved documents are available which excludes hot documents such as the current 802.11n draft.
