  1. H2GF COMMENTS ON ALLOCATION FOR WIRELESS ACCESS SYSTEMS OPERATING IN THE FREQUENCY RANGE 5150 MHz TO 5875 MHz Peter Karlsson Chairman H2GF Regulatory Working Group 2 June 2000

  2. Agenda • Leave out HIPERLAN 0, no good proposition! • HIPERLAN/2 technologies. • H2GF objectives & backgound • Band partitioning in the 5 GHz band: • IEEE 802.11a to be permitted operation? • partition between HIPERLAN type1 and type 2? • partition between private/public systems? • H2GF suggestions and goals.

  3. General H2GF Objectives • Achieve globally interoperable products • Lower equipment cost • High total system capacity • No band partitioning • Seamless interoperation • Private and public use with the same terminal • Connection-oriented with support for QoS

  4. H/2 The Enabling Standard • Broadband communication, up to 54 Mbit/s • Plug & play radio network (MAC, DFS) • Security, authentication & encryption • Generic architecture allows interoperation: - legacy LAN (Ethernet) - PPP-based access (e.g. for VPN) - 3G cellular networks - IEEE 1394 (Firewire) - ATM

  5. Office HiperLAN2 - Seamless wireless datacom solution Local Area WLAN Datacom Airport Home Hotel & Conference Roaming Trainstation Publicspace Wide area cellular datacom

  6. HiperLAN2 Technologies • MAC scheduler at AP • Centralised control • Supports uniform traffic load • Inter & Intra system interference mitigation • Dynamic Frequency Selection (DFS) • Link Adaptation • Transmit Power Control (TPC) • Support of smart (sectored) AP antennas

  7. Band Partitioning Remarks • Licence exempt uncoordinated spectrum use within global standards has advantages to the total system capacity. • In combination with enabling technologies it is the best use of spectrum also for mixed services • However, the system must support interference mitigation and guaranteed QoS

  8. Spectrum Requirement Notes Only 5150-5250 MHz has currently been agreed by footnote in the Radio Regulation as an allocation to mobile services by ITU-R. The ERC Decision has allocated the other parts of the band within Europe only. ERC allocation is for HIPERLANs based on CEPT co-existence studies. Interference reduction requirements: DFS, TPC, Uniform traffic load etc.

  9. IEEE 802.11a to be permitted operating in these band? • H/2 and IEEE 802.11a same PHY layer • only 5150-5350 MHz as common bands • Different MAC algorithms • No centrally controlled traffic load over channels • No Dynamic Frequency Selection (DFS) • Follow the ERC allocation for HIPERLANs • co-existence study needed before allocation of spectrum to IEEE 802.11a, +DFS & TPC!

  10. Need to address public and private spectrum partitioning? • The system must fulfil the requirements for operation of networks and critical services • The services should not be regulated by licensing but by means of system enabling technologies - MAC, DFS, QoS & Security • The spectrum should not be partitioned for private and public services - seamless use!

  11. Partition HIPERLAN Type 1 from HIPERLAN Type 2? • The outcome of this issue depends on the different physical layers, idea for further study: H/1 could adapt to H/2 channels or H/2 PHY. • It also depends on the answer to the question; what will be the high sales volume application? • Commercial support for H/2 is very strong, today more than 30 members in H2GF! • H/2 must be allowed operation in 455 MHz.

  12. Membership Status - Commercial Support ADC Communications Alcatel Adaptive Broadband Axis Bosch Cambridge Silicon Radio Canon Dell Elisa Emtac Ericsson Eumitcom Grundig HLAN Intersil KDI Lucent Matsushita Communications Mediascape Mitsubishi Motorola National Semiconductors Nokia NTT Philips Samsung • Siemens • Silicon Wave • Sony International • Systemonic AG • TDK • Telia • Texas Instruments • Thomson • 3Com • T-Span • Wireless Communication • Xircom

  13. Band Plan According to ERC Co-existence studies have to be made before any change of the ERC decision band plan can be made.

  14. H2GF Goals • Certified interoperable products on the market early 2002 • Ensure unlicensed spectrum allocated on all global major markets • Complementing the 3G cellular datacom system • Visit us at http://www.hiperlan2.com

  15. Conclusions & Suggestions • HiperLAN2 fulfils spectrum requirements. • HiperLAN2 is a system that can guarantee QoS levels without band partitioning. • Seamless operation in private and public environments necessary. • High system capacity - no band partitioning! • Co-existence between H1/H2/802.11 needs to be solved preferably by technical means: BRAN
