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

Regulatory Competence GroupTesting

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 IEEE802.11

specifications HiperLAN2 standard included very advanced features and

superiour quality of service Initial IEEE802.11 specs much less ambitious When HiperLAN2 standard was completed, IEEE802.11 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

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

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

The Co-operation results

HiperMAN and IEEE802.16-2004 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 IEEE802.16 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
