BROADCAST APPLICATIONS OF WiMAX NETWORKS
“What is the use of a book,” thought Alice, “without pictures or conversations?”
—Lewis Carroll, Alice in Wonderland (1865)
WiMAX networks have been designed to provide broadband wireless access with QoS parameters, and provide assured service flows for each connection. WiMAX also has a service class, “real-time polling service” (rtPS), which is designed to cater to variable rate data packets such as those generated in MPEG with low latencies in order to meet video transmission requirements. Transmission of video over wireless networks, prior to deployment of WiMAX systems, had always been a challenge because of the high sustained bit rates, which need to be maintained for every user on the network. ...
