ABSTRACT
The new era of communication, currently
employed in some parts of the world, is
Worldwide Interoperability for Microwave
Access (WIMAX). It is the latest technology
which is approved by IEEE 802.16 group, which
is a standard for point-to-multipoint wireless
networking. Wimax vision is to deliver “last
mile” broadband connectivity to home or
business locations, also its data rates are
comparable with Cable and Digital Subscriber
line (DSL) rates.
INTRODUCTION - “The Road to
WIMAX”
Imagine a technology that can reach even into
the remote areas or the suburbs where the access
to power plants is even difficult. This innovation
technology will provide transfer rates of multiple
Megabits to the users within a range of several
kilometers. As we know the demand for wireless
has raised rapidly from 5.7 million in 2002 to
200 million in 2006. The global Wimax market
is growing at the rate of 30% per year and is
expected to touch $2.8 billion by 2009 from the
present $ 600 million. The number of Wimax
users is forecasted to each 14.9 million in 2009.
Wimax based solutions are more flexible and
secured. They provide an outstanding service and
are very much cost effective.
BACKGROUND
The demand for wireless in increasing day by
day. Presently, the networks are only available in
commercial buildings, homes etc. But people
want wireless internet access wherever they go
like shopping malls, airport, roaming around the
city etc. They want to have all the facilities that a
cable broadband provides like surfing the web,
downloading files, video conferencing etc. with
higher data rates. In the context Wimax is
positioned as an excellent option. Moreover, the
possibility of offering broadband services in
combination with voice services will gradually
lead to narrow band WLL substitution.
Application & Forum
Wimax is a moniker for IEEE 802.16 interface
specifications promoted by the industry trade
organization “Forum for Worldwide
Interoperability for Microwave Access”.
Members of the Wimax forum include operators,
equipment & component makers. The Wimax
forum has introduced a new standard for wireless
broadband access. Wimax forum has adopted
certain profiles based on the 802.16 standard for
interoperability testing and Wimax certification
which operates in the frequency bands of
2.5GHz, 3.5GHz, 5.8GHz and also which are
licensed by various government authorities. The
purpose of The Wimax Forum is to gather
together the industry participants and form and
communicate a clear vision for where Wimax is
heading, what stages and market development
focus the standards.
