Basic Concept for mm-Wave WPAN September, 2003 Basic Concept for mm-Wave WPAN Yuichi Shiraki Oki
High Coexistence with existing microwave system <month year> doc.: IEEE 802.15-03/119 September, 2003 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 Reed Fisher, Oki
WPAN (microwave) Piconet is formed using omni-directional antenna September, 2003 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
September, 2003 mmW WAPN 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
Conclusion Advantage of mmW WPAN September, 2003 Conclusion Advantage of mmW WPAN -Network advantage in addition to technical one Utilizeing directional antennas：Interference, frequency re-usage - Area connection, Area expansion utilizing the present 15.3MAC 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
