W WPAN Concept The following individuals support this proposal: Akira AKEYAMA (NTT Advanced Technology Corp. ) Kiyohito TOKUDA (Oki Electric Industry Co. , Ltd. ) Toshiyuki HIROSE (Siemens K. K. ) Hidenori SIMAWAKI (NEC Corp. ) Kouichi SAKAMOTO (Murata Manufacturing Co. , Ltd. ) Submission 2 Kiyoshi Hamaguchi, CRL

September, 2003 doc. : IEEE 802. 15 -03/0347 r 0 mm. W Propagation Characteristics • Rain attenuation • Atmospheric oxygen (O 2) Absorption, i. e. , 60 GHz …Short-range radio link …Smaller interference, compared to microwaves Ref: ITU-R Rec. P. 676 -3 60 GHz mm. W band Submission 3 Kiyoshi Hamaguchi, CRL

September, 2003 doc. : IEEE 802. 15 -03/0347 r 0 mm. W Radio-Link Characteristics • Very wide frequency band …High speed transmission • Radiated power limitation, i. e. 10 m. W, for unlicensed use …Short-range communication • Usage of directional antennas …Long-distance communication Submission 4 Kiyoshi Hamaguchi, CRL

September, 2003 doc. : IEEE 802. 15 -03/0347 r 0 WPAN Concept • Short-range radio communications network （~10 m distance, among several nodes, independent local-area-network） • Possible wireless network between gameequipment, home appliance, video-signals transmission and PC/peripheral etc • Short-range/high-speed link … mm. W is suitable • Easy to link among nodes … ad hoc link protocol Submission 5 Kiyoshi Hamaguchi, CRL

September, 2003 doc. : IEEE 802. 15 -03/0347 r 0 Possible Wireless Links (1/2) Directional antenna (a) Tx & Rx • P-to-P Tx & Rx • Very high-speed transmission • Long-distance link Omni-directional antenna (b) Tx & Rx • P-to-MP Tx & Rx • High-speed transmission • Short-range link Tx & Rx Submission 6 Kiyoshi Hamaguchi, CRL

September, 2003 doc. : IEEE 802. 15 -03/0347 r 0 Possible Wireless Links (2/2) Omni-directional antenna (c) Tx & Rx • P-to-MP • High-speed transmission Tx & Rx Submission • Wide-area (multi-hop) link Tx & Rx 7 Kiyoshi Hamaguchi, CRL

September, 2003 doc. : IEEE 802. 15 -03/0347 r 0 WPAN Scenarios • In a house: - All appliances with Tx & Rx are mutually connectable - Wirelessly Controllable appliances Utilization example in a house • In a meeting room: - Notebook PC with mm. W-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 Submission 8 Kiyoshi Hamaguchi, CRL

September, 2003 doc. : IEEE 802. 15 -03/0347 r 0 Advantages of mm. W system compared to UWB • Good coexistence between mm. W system and 802. 11 a/b/g & Bluetooth because of large frequency difference • Good coexistence among mm. W systems because of larger path-loss compared to microwave band systems • Higher speed transmission; i. e. , more than 1 Gbps • Exploitation of antenna directivity 　…Longer transmission distance • Simple spectrum mask • Simple modulation/demodulation • Simple signal processing • Poorer frequency stability; i. e. , within +/-500 ppm Submission 9 Kiyoshi Hamaguchi, CRL

September, 2003 doc. : IEEE 802. 15 -03/0347 r 0 Conclusions • mm. W WPAN concept and images are proposed • Advantages of mm. W system compared to UWB are described Submission 10 Kiyoshi Hamaguchi, CRL
