QoS Management for Broadband IEEE 802.16 based Networks in FDD Mode

摘要

Broadband Wireless Access (BWA) has become the best way to meet residential and small business demand for high speed Internet access and multimedia services. As an emerging technology for broadband access, it provides the following advantages over its wired competitors: 1) rapid deployment and ease to implement; a BWA network can be installed rapidly without extensive underground cable infrastructure as is the case of Cable or DSL networks, 2) high scalability; carriers can expand the BWA network as subscriber demand for bandwidth grows by adding channels, or cells, 3) lower maintenance and upgrade costs and 4) higher data rates. However, the wide-scale adoption of BWA systems will be determined by its ability to overcome cost and performance barriers. If BWA can meet these challenges it could easily be the next revolution in wireless networks systems such as WLANs.
