WiMAX is a standards-based
technology enabling the delivery of last mile wireless broadband
access as an alternative to wired broadband like cable and
DSL. WiMAX provides fixed , nomadic, portable and, soon, mobile
wireless broadband connectivity without the need for direct
line-of-sight with a base station. In a typical cell radius
deployment of three to ten kilometers, WiMAX Forum Certified™
systems can be expected to deliver capacity of up to 40 Mbps
per channel, for fixed and portable access applications.
This is enough bandwidth to simultaneously support hundreds
of businesses with T-1 speed connectivity and thousands of
residences with DSL speed connectivity. Mobile network deployments
are expected to provide up to 15 Mbps of capacity within a
typical cell radius deployment of up to three kilometers.
It is expected that WiMAX technology will be incorporated
in notebook computers and PDAs by 2007, allowing for urban
areas and cities to become “metro zones” for portable
outdoor broadband wireless access.
