  1. Proposed Agenda item for WRC 2002/3, Spectrum for high performance RLANs (i.c. ETSI HIPERLAN/2) ()

  2. Complementing Wireless Technologies with personal, local and global scope Personal Area Local Area Bluetooth RLANs Wide Area 3G Mobile

  3. Vehicle Walk Outdoor Stationary Walk Indoor Stationary/Desktop Positioning - Mobility vs. Bitrate RLANs:HIPERLAN/2 IEEE 802.11 MMAC 3rd Generation Mobile Mobility Bluetooth LAN 0,1 1 10 100 1000Mbps User Bitrates

  4. Wireless LAN Driving Factors • Huge growth in need for access to Internet & Intranet with bandwidth hungry multimedia applications • Predicted growth in “Mobile Computing” and “Wireless Office” due to a change in working behavior • Massive growth in “wide range” wireless and mobile communications • Strong demand for LAN-like performance - users do not like a compromise • World-wide portability

  5. Internet IWU SGSN GGSN Wireless LAN/Access Scenario Home GPRS/UMTS Office ISP Ethernet

  6. HIPERLAN/2 Standard • Radio Physical layer: 6 - 54 Mbit/s • same as IEEE 802.11a and MMAC-HS • DLC Layer: Packet Service with controlled QoS for multimedia support • Convergence Layers for Ethernet, IP, UMTS, ATM, IEEE1394 • Conformance Test specifications • Status: • full drafts of Radio Physical Layer, DLC Layer and Ethernet convergence near completion • Conformance Test specification in preparation • All planned to be completed in year 2000

  7. Emerging Industry Consensus on 5 GHz RLANs • Based on regional spectrum decisions • FCC: U-NII, CEPT: HIPERLAN • 5 GHz RLAN standards by ETSI, IEEE and MMAC • Same radio specification • IEEE 802.11 focuses on wireless LAN applications • ETSI (HIPERLAN) focuses on high rate access applications with Quality of Service • MMAC-HS addresses both types of applications and works closely with ETSI and IEEE

  8. Required Regulatory action at WRC level • A world-wide allocation to facilitate cross-border/international usage is needed • Compatibility studies are underway in the ITU-R (JRB 8A-9B) • based on earlier work by FCC (U-NII) and CEPT (HIPERLAN/2) • should be concluded well before 2002 • WRC 2002 should make the necessary decisions • Europe is in a leading position: • ERC DEC 99(NN) and ETSI HIPERLAN standards

  9. Hiperlan Hiperlan 5.15 - 5.35 5.470 - 5.725 5100 5200 5300 5400 5500 5600 5700 5800 Current RLAN Spectrum at 5 GHz Licensed exempt 455 MHz Europe High Speed Wireless Access 5.15 - 5.25 Japan 100 MHz U-NII U-NII 5.15 - 5.35 5.725 -5.825 Unlicensed 300 MHz US

  10. ITU-R Work on RLANs • SG8 and SG9 • JRG 8a-9B: • DNR on MSS / RLAN sharing to be approved October 1999 • PDNR on RLAN Characteristics • PDNR on Spectrum Requirements for Nomadic Access Devices

  11. Summary • HIPERLANs are a major opportunity for the European industry • World-wide, harmonised spectrum is needed to reap the benefits • With proper backing of the European Administrations at WRC 2002, a world-wide allocation is feasible • Sharing with other incumbents in the 5 GHz band has been studied extensively and is considered feasible (see Draft ERC Decision 99(NN) • The groundwork is being prepared by ITU-R JRG 8a-9B • The ETSI BRAN project members will support the preparations for WRC 2002
