OxigenAbsorbance
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.

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)

•WiGig is a multi Gigabit wireless standards and technology that enhances the usability of WiFi beyond connectivity and networking
•Multi Gigabit connectivity imposes higher capacity to the existing Cellular systems
•To increase capacity, increased small cell density, higher throughput and spectral efficiency systems are required
•mmWave enabled HetNet can significantly increase the system capacity
•WiGig as a proven mmWave technology can be extended to mmWavecellular systems.
•New generations of cellular systems evolve every 5-7 years, mmWave technology is a great candidate for beyond 4G systems
