Introduction
The peak of BRAN activity is in the past
Current activities
Some activity in the HiperMAN area
Some activity towards regulation in wireless access domain
Interesting to learn from

Spectrum regulatory issues, Harmonized Standards

4. Regulatory Competence Group
Achieved a number of harmonized standards
Harmonize standard regulate the use of broadband wireless access devices in Europe
Part of the work needs to address the same for IMT-Advanced family of systems
To ensure balanced treatment of IMT-Advanced family technologies, this work will be continued in a joint group

HiperLAN2
In best day well over 100 delegated at each meeting
Many big ETSI member companies contributing to the standard
However, many of them also contributed to IEEE specifications
HiperLAN2 standard included very advanced features and superiour quality of service
Initial IEEE specs much less ambitious
When HiperLAN2 standard was completed, IEEE products were already getting traction in the market
At that point some big companies decided not to market HiperLAN2
Lessons:
Superior technologies do not always win
Window of opportunity is limited

8. HiperAccess (above 11GHz)
Standards successfully completed
Market for systems above 11 GHz limited, equipment expensive because of high frequencies
Only one company implemented the standard
The company was bought by another company
Profit margins were better with proprietary systems
Lessons:
Predicting market opportunities several years ahead is not always easy

11. ETSI-WiMAX Co-operation agreement
Co-operation Agreement signed in 2005
Joint work between ETSI Technical Committee BRAN and WiMAX Forum
Covered by BRAN Work Items
Each year the agreement is amended with new Work Items
Joint projects
Report to both ETSI BRAN and WiMAX Forum
Are funded equally by ETSI and WiMAX Forum
Documents respect ETSI drafting rules and are published by ETSI
Copyright notice of ETSI and WiMAX Forum
WiMAX Forum Logo added to the standard ETSI logo

12. The Co-operation results
HiperMAN and IEEE harmonized
ETSI has delivered 500+ test cases in TTCN-3, thus completing all tests selected at the time for certification by WiMAX Forum.
TTCN releases were made every two weeks
Efficient integration and validation environment was set up
Several on-line databases set up for reporting and tracking problems in validation
More then 2000 problems recorded, average resolution time 9 days
Validated test cases used by WiMAX nominated certification laboratories.
The co-operation agreement expired and was not renewed
WiMAX is continuing on their own

HiperMAN
Standardized some features that were later embraced by industry and included in IEEE specs
Developed test specifications that are the basis of industry certification (controlled by WiMAX Forum)
Lessons:
Member companies are probably rather satisfied with what they achieved for themselves
