ACCRONYMS
WiMAX - Worldwide Interoperability for Microwave Access, a
certification
mark for products that pass conformity interoperability tests
for the IEEE
802.16 and ETSI HiperMAN standards.
IEEE- Institute of Electrical and Electronics Engineers,
Inc.
ETSI -European Telecommunications Standard Institute
HiperMAN -High Performance Radio Metropolitan Area Network

What is the WiMAX forum?
www.wimaxforum.org
The WiMAX Forum is an industry-led, non-profit corporation
formed topromote and certify compatibility and interoperability of
broadband wirelessproducts.
Our member companies support the industry-wide acceptance of the
IEEE802.16 and ETSI Hiper MAN wireless standards.
What this means for you:
For network operators this means equipment interoperability
across vendors
For component vendors this means fewer product variations and
highervolumes
For end-users this means faster and cheaper access that is more
widelyavailable

Key Benefits of the WiMAX Standard
For Equipment Vendors
- Standards-based, common platform encourages innovation.
- Concentrate on specialization (i.e. Base Stations or CPEs) -
nolonger need to create an entire end-to- end solution as in
proprietarymodel.
For Consumers
- Consumers can receive services in areas with little
infrastructure,developed countries, rural & hard-to-service
areas.
- Increased number of players in the market which means
options.
- Quick trickle down effect of cost savings to consumers.

Key Benefits of the WiMAX Standard
For Service Providers
- Enables a lower initial CAPEX investment.
- Eliminates commitment to a single vendor, a typical by-product
ofthe proprietary technology model.
- Wireless systems significantly reduce operator investment
risk.
For Component Makers
- Standardization creates a volume opportunity for chip set
vendors.

Coverage
Clear Line of Site (Rural Areas)
- Average distance of 30km claimed by most vendors
Near Line of Site (Semi- Urban)
- Average Distance of 10km claimed by most vendors.
Non Line of Site (Urban and Hilly areas)
- Average Distance of 4Km claimed by most vendors
These Distances depend on factors like Antenna gain, Congestion
(Noise)
Geographical factors and Interference.
