1.1 About WiMAX
1.1.1 Introduction to WiMAX
Emanating from the broadband world and using all-IP architecture, mobile WiMAX is the leading
technology for implementing personal broadband services. No other technology offers a full set of
chargeable and differentiated voice, data, and premium video services in a variety of wireless fashions -
fixed, portable and mobile - that increase revenue and reduce subscriber churn.
WiMAX technology is the solution for many types of high-bandwidth applications at the same time
across long distances and will enable service carriers to converge the all-IP-based network for triple-play
services data, voice, and video.
WiMAX with its QoS support, longer reach, and high data capacity is positioned for fixed broadband
access applications in rural areas, particularly when distance is too large for DSL and cable, as well as in
urban/suburban areas of developing countries. Among applications for residential are high speed
Internet, Voice Over IP telephony and streaming video/online gaming with additional applications for
enterprise such as Video conferencing, Video surveillance and secured Virtual Private Network (with
need for high security). WiMAX technology allows covering applications with media content requesting
more bandwidth.
WiMAX allows portable and mobile access applications, with incorporation in notebook computers and
PDAs, allowing for urban areas and cities to become “metro zones” for portable and mobile outdoor
broadband wireless access. As such WiMAX is the natural complement to 3G networks by offering
higher bandwidth and to Wi-Fi networks by offering broadband connectivity in larger areas.
The WiMAX Forum is an organization of leading operators and communications component and
equipment companies. The WiMAX Forum’s charter is to promote and certify the compatibility and
interoperability of broadband wireless access equipment that conforms to the Institute for Electrical and
Electronics Engineers (IEEE) 802.16 and ETSI HiperMAN standards. The ultimate goal of the WiMAX
Forum is to accelerate the introduction of cost-effective broadband wireless access services into the
marketplace. Standards-based, interoperable solutions enable economies of scale that, in turn, drive
price and performance levels unachievable by proprietary approaches, making WiMAX Forum Certified
products.
