mmW Propagation Characteristics
• Rain attenuation
• Atmospheric oxygen (O2) Absorption, i.e., 60GHz
…Short-range radio link
…Smaller interference, compared to microwaves
60GHzmmW band

mmW Radio-Link Characteristics
• Very wide frequency band
…High speed transmission
• Radiated power limitation, i.e. 10mW, for unlicensed use
…Short-range communication
• Usage of directional antennas …Long-distance communication

WPAN Concept
• Short-range radio communications network
（ ~10m distance, among several nodes, independent local-area-network ）
• Possible wireless network between game-equipment, home appliance, video-signals transmission and PC/peripheral etc
• Short-range/high-speed link … mmW is suitable• Easy to link among nodes … ad hoc link protocol

WPAN Scenarios
Utilization example in a house
• In a house:
- All appliances with Tx & Rx are mutually connectable
- Wirelessly Controllable appliances
• In a meeting room:
- Notebook PC with mmW-Tx & Rx
- Share presenter’s material on their PCs
- Slide data can be transmitted to projector
• Other situations:
- railway station, inside train or bus, store etc. Utilization example in a meeting room

Advantages of mmW system compared to UWB
• Good coexistence between mmW system and 802.11a/b/g & Bluetooth because of large frequency difference
• Good coexistence among mmW systems because of larger path-loss compared to microwave band systems
• Higher speed transmission; i.e., more than 1Gbps• Exploitation of antenna directivity … Longer transmission distance• Simple spectrum mask• Simple modulation/demodulation• Simple signal processing• Poorer frequency stability; i.e., within +/-500ppm
