  2. Basic Concept for mm-Wave WPAN Yuichi Shiraki Oki

  3. Features of mmW WPAN • High Coexistence with existing microwave system • High Coexistence with mmW system utilizing directional antennas • High frequency re-usage using directional antennas • mmW WPAN and its Network utilizing millimeter-wave directional antennae Yuichi Shiraki Oki

  4. mmW WPAN (microwave) • Piconet is formed using omni-directional antenna • Each piconet has its own frequency • (to avoid interference among piconets) • Area expansion of WPAN is very restricted and has less network flexibility (Child piconet, Neighboring piconet) Piconet A Piconet B Yuichi Shiraki Oki

  5. mmW WPAN Network Basic Concept • mmW WPAN consists with space divided Piconets utilizing directional antennas • Each piconet can be controlled independently • Each terminal has possibility to supports multi-piconets. External NW Yuichi Shiraki Oki

  6. Conclusion • Advantage of mmW WPAN • -Network advantage in addition to technical one • Utilizeing directional antennas：Interference, frequencyre-usage • - Area connection, Area expansion utilizing the present 15.3c • Basic concept for mmW WPAN Network is introduced • Issues to be clear • - Detail of Application and application requirement • - Additional MAC function to be required • - interference among piconets Yuichi Shiraki Oki
