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

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

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)

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
