Is WiMAX new? When did it start?
WiMAX is relatively new in terms of a standards initiative - and in
particular, the launch of numerous WiMAX technologies supporting chipsets by
Forum members. However, much of the technology being incorporated into the IEEE
802.16 technology set is existent in the industry today and well tested. A
number of best of breed broadband radio manufacturers have been offering various
elements used in WiMAX for several years as proprietary technology. However,
vendors rarely offered consistent iterations of radio modulation and other
techniques---ensuring that solutions had to be specific to a single vendor. This
is especially true on the fixed wireless side. And even more so for unlicensed
band fixed wireless. However, mobile broadband wireless technologies suffered
from the fragmentation of multiple proprietary approaches.
This means that much of the technological capability of WiMAX is relatively
mature. In fact, the radio vendors who are members of the forum have deployed
equipment in over 125 nations around the globe with trials and deployments
exceeding 275. The combination of these advanced technologies into two standards
packages for Fixed and Mobile broadband wireless combined with new generation
optimized chipsets and tested and certified interoperability between radio
manufacturers deliver a robust and powerful technology. This capability can
match or exceed the performance and cost factors of other broadband
technologies. This can all be achieved without traditional wireline tethers.
On the horizon, plans are to expand the WiMAX product capability as well as the
early underpinnings of the next version of WiMAX, which will incorporate
increasingly newer technologies. Also, the next major version of the 802.16
standard 802.16m, is already in the process of being defined. This version will
offer even better throughput, spectral efficiency and capabilities along with
increased interoperability.
