3. Broadband Market Development
Early Proprietary Deployment
Fixed Access targeted
The 802.16 Standard Family
IEEE 802.16 WG formed in 1998 to develop a standard for
Wireless MAN (primarily Fixed Wireless)
Initially 10-66 GHz band considered, later modified to
focus on 2-11GHz NLOS
IEEE 802-16-2004 standard ratified in 2004
DEC 2005 specification for 802.16e (802-16-2005) was
completed adding mobility support and operation in 2-6
GHz among other enhancements.

4. The 802.16 standards have a very broad scope with many
incompatible options
World-wide Interoperability for Microwave Access
p y
WiMAX (similar to WiFi) is not a technology but a certification
framework.
Framework
◦ Use of the IEEE 802.16 Air interface
◦ Certify Interoperability at the air interface as well as the
e o
network
◦ Promotes the use of BWA
The WiMAX forum defines commercial “profiles” and
promoted interoperability of products through testing and
certification

Standardization and Interoperability are the path to
“volume economics”

11. Devises
◦ Chipset – Basic Air interface interoperability
◦ Multi-Frequency
◦ Devise functionality and performance

12. Network Interfaces
◦ Open R3/R6/R8 inrefaces

13. Roaming
◦ Models agreements (Unilateral, Bilateral and Hub
model)
◦ Establishment of wholesale/Hub WRX

14. WiMAX is not the only technology out there
More capable terminals with multi-technology
support
Handoff (inter & intra technology) is essential

15. Standardization and interoperability have a
proven track record when it comes to
technology success
The benefits are realized by subscribers,
operators and vendors alike
There are numerous challenges that must be
addressed before WiMAX can realize its
dd db f li it
potential
Operators and vendors must cooperate
under the leadership of the WiMAX forum to
cross those hurdles
