Sidebar: WiMax Basics
Computerworld -
- There are two versions: 802.16-2004 for "fixed" access, 802.16e for mobile access.
- QoS requirements are specified in the standard.
- Security (DES, 3DES and AES encryption) is specified in the standard.
- WiMax supports IP and traditional TDMA (circuit-switched) applications.
- Licensed spectrum is preferred for carrier-class WiMax service offerings. Early U.S. services are being developed for 5.8-GHz (unlicensed) band, because many regional carriers committed to WiMax don't hold licenses in the 2.5-GHz band, also approved for WiMax use in the U.S. Outside the U.S., licensed 3.5-GHz bands will support WiMax. U.S. approval for 3.5-GHz WiMax usage is expected eventually.
