WiMax The Next Broadband Wireless Revolution Paper Presentation And Power Point

WiMax (worldwide Interoperability for Microwave Access) is the recently approved IEEE 802.16 wireless metropolitan area network (MAN) standard for wireless access. WiMax is the real wireless architecture by which the wireless access range can extended to 49.6Kms compared with Wi-Fi 91mts and Bluetooth’s 9mts. WiMax 802.16 has a single carrier modulation scheme that operates between 10GHz and 66GHz radio frequency and requires line of sight towers for the connection to work. The new ratified 802.16a extension uses a lower frequency range of 2GHz to 11GHz, and does not require line of sight towers. It also boasts 70Mbps data transfer rate that can support thousands of users.
