  • 26. INTEL CONFIDENTIAL26 mmWave Path loss Comparisons Oxigen Absorbance Note: Assumption is that we are using the same TX/RX antennas gain for all bands. But it means that antenna size for 30GHz will be two times larger than for 60GHz (aperture size by 4 times bigger!). In the case of hard limitations on antenna size additional 6dB advantage will be lost for low frequency bands. 2.3 GHz 30 GHz 40 GHz 60 GHz

  • 30. INTEL CONFIDENTIAL30 Early Simulation result • For SU-MIMO mode mmWave communication system has shown 5.4 Gbps/cell throughput (90 Mbps/UE for 60 UE/cell) for 50 m Small cell size. (No overhead assumed) • For MU-MIMO mode simulations, under reasonable assumptions, mmWave Small cell demonstrates 59 Gbps/cell throughput (about 1 Gbps/UE for 60 UE/cell) for 50 m Small cell size. (matching analytical results previously presented) • The system without intelligent power transmit power control may violate FCC requirements on signal power density. ITPC scheme prevents this violation without substantial system performance metrics degradation (SW controlled EIRP/UE)
