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

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.

6. 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
