WiMAX: Technologies, Performance Analysis, and QoS |
|
|
 Description
As the demand for broadband services continues
to grow worldwide, traditional solutions, such as digital cable and
fiber optics, are often difficult and expensive to implement,
especially in rural and remote areas. The emerging WiMAX system
satisfies the growing need for high data-rate applications such as
voiceover IP, video conferencing, interactive gaming, and multimedia
streaming. WiMAX deployments not only serve residential and enterprise
users but can also be deployed as a backhaul for Wi-Fi hotspots or 3G
cellular towers. By providing affordable wireless broadband access, the
technology of WiMAX will revolutionize broadband communications in the
developed world and bridge the digital divide in developing countries.
Part of the WiMAX Handbook, this volume focuses on the technologies
behind WiMAX, its performance capabilities, and its control mechanisms.
The book introduces programmable baseband processors suited for WiMAX
systems, describes an innovative methodology for the design of
multi-band WiMAX antennas, addresses space-time block codes, and
reviews space-frequency/space-time-frequency code design criteria. It
also proposes a combined call admission control and scheduling scheme,
focuses on the performance analysis of the IEEE 802.16 mesh mode, and
analyzes the performance of both single-input-single-output and
space-time-block-coded OFDM systems in mobile environments. The final
section establishes a framework of an ideal reservation period
controller, examines the ecosystem in which scheduling for IEEE 802.16e
systems must be performed, and presents a fuzzy logic controller for
admission control. With the revolutionary technology of WiMAX, the
lives of many will undoubtedly improve, thereby leading to greater
economic empowerment.
