A Discussion Paper on Standard Harmonization GRSC-1 (Ottawa) April 2003
Content • Standard Organisations - FWA/BWA Interoperability • Look at Resulting Standards • Possible Causes for Differences • Impact of non-harmonization • Towards Harmonization – Current Methods • Improved Harmonization - Possible Avenues GSC-8, OTTAWA
Standard OrganisationsFWA/BWA Interoperability Still active • IEEE 802.16 • ETSI BRAN HIPERACCESS & HIPERMAN Now inactive • BWIF • W-DSL GSC-8, OTTAWA
IEEE 802.16a Three modes (OFDM, OFDMA and SC) Optional mesh mode Cover licensed and licence-exempt cases 2kFFT OFDMA ETSI BRAN HIPERMAN One main mode (OFDM) OFDMA option Optional mesh mode Uplink OFDM sub-chanelization Currently OFDMA option using 256FFT only FEC using Reed-Solomon concatenated with convolutional code (RS-CC) Optional BTC Look at Resulting Standards GSC-8, OTTAWA
Possible Causes for Differences • Different membership • Different premises • International as opposed to regional or national organization • Different voting structures GSC-8, OTTAWA
Impact of non-harmonization • Participation of companies and persons to multiple organizations ($, time, resources) • Reduced volume of equipment • Higher cost • Mixed signals to the market (Who’s right?) GSC-8, OTTAWA
Towards HarmonizationCurrent Methods • Liaison officers • Liaison statements • Groups of interest participating in multiple standard organizations (i.e. OFDM Forum, TDD Coalition, etc.) • Co-located meetings GSC-8, OTTAWA
Improved Harmonization - Possible Avenues (1) • Strong operator/user participation (at least for the development of the system requirements) • Commitment from the operator/user • Groups of interest invited to participate within the ”official” standard organizations (incl. industry forums) • Consider migration paths from proprietary solutions to standard solutions • Consider phasing the future enhancements (do not try to do everything the first time) GSC-8, OTTAWA
Standard Organization A Standard Organization B Joint Standard Development Group One or more output (i.e. considering regional regulation, market peculiarities, etc.) Improved Harmonization - Possible Avenues (2) GSC-8, OTTAWA
Possible Avenues for Improved Harmonization (3) ??? GSC-8, OTTAWA
