  8. Oki/CRL mm-Wave WPAN SystemPHY Requirements (2) TG3a Alt-PHY Technical Requirements (IEEEP802.15-02/371) mm-Wave WPAN System • 100mW or less @100Mbps • 250mW or less @200Mbps • Power save function • To be specified Power consumption • Capable of fitting into a form factor • consistent with a camera,PDA,etc • Capable of fitting into a form factor • consistent with a camera,PDA,etc Form factor Complexity • Minimal to enable mass commercial • adaptation for cost sensitive products • Minimal to enable mass commercial • adaptation for cost sensitive products • Poorer frequency stability: • within +/-500ppm • Simple signal processing • Alt-PHY operates with the 802.15.3 MAC • without fundamental changes. • (Supplements can be added which • expand the capability of the system.) Supplements to 802.15.3 functionality • Alt-PHY operates with the 802.15.3 MAC • without fundamental changes. Ref:IEEE802.15-03/371r2 Reed Fisher, Oki

  9. Oki/CRL mm-Wave WPAN System PHY Requirements (3) TG3a Alt-PHY Technical Requirements (IEEEP802.15-02/371) mm-Wave WPAN System • Comply with necessary geopolitical or • regional regulations • Comply with necessary geopolitical or • regional regulations Regulatory Directionality of antenna • Assumption of Omni-directional antenna • No exclusion of directional antenna • if needed to mitigate specific user problems Ref:IEEE802.15-03/371r2 Reed Fisher, Oki

  10. System Features • Utilization of unlicensed millimeter-wave band - Small, line of sight, coverage area but high data rate (～622Mbps) - High coexistence with the existing microwave band wireless systems • Countermeasure in use of millimeter-wave band Complete cancellation of phase noise and frequency-offset by self-heterodyne transmission and detection technique Ref:IEEE802.15-03/119r4 Reed Fisher, Oki

  11. Advantages of mmW system compared to UWB - Coexistence - • No interference to other systems in microwave band because of large frequency difference • Good coexistence among mmW systems because of both larger path-loss and attenuation for diffraction waves, compared to microwave band systems Ref:IEEE802.15-03/371r2 Reed Fisher, Oki

  12. Advantages of mmW system compared to UWB - System Design - • Exploitation of antenna directivity to obtain longer transmission distance and higher interference immunity (UWB may be not allowed the use of high gain antennas) • Simple modulation/demodulation (Spread spectrum schemes are essential for UWB) • Simple signal processing (For UWB, complex technologies such as rake-receiver, or high frequency A/D, D/A converter and DSP will be needed for signal processing) Ref:IEEE802.15-03/371r2 Reed Fisher, Oki

  13. Advantages of mmW system compared to UWB - System Design - • Poorer transmitter frequency stability allowed • ( +/-500ppm ) • Low cost “self heterodyne” receiver Ref:IEEE802.15-03/371r2 Reed Fisher, Oki

  14. Advantages of mmW system compared to UWB - Other items - • Higher speed transmission; i.e., more than 1Gbps • Simple spectrum mask. UWB must fit into severe FCC spectrum mask • Effective usage of frequency bandwidth which depends on the demand of transmission rate Ref:IEEE802.15-03/371r2 Reed Fisher, Oki
