8 Technologies Driving the Future of Wireless Multi-RAT Enhanced PHY mmwave Massive MIMO Advanced Wireless Networks Improve bandwidth utilization through evolving PHY Level and flexible numerology Utilize potential of extremely wide bandwidths at frequency ranges ones thought impractical for commercial wireless. Dramatically increased number of antenna elements on base station. Consistent connectivity meeting the 1000x traffic demand for 5G Densification SDN NFV CRAN 8

9 NYU Wireless and NI Collaborate on mmwave Channel Sounding Channel sounding at 28, 38, and 72 GHz Dense urban environments (New York City) Prove viability of mmwave for mobile wireless communications Results NYU published first results in June GPP calls for further investigation in 2015 FCC proposes new rules for mmwave in 2015 Prof. Ted Rappaport Y. Azar, G. N. Wong, K. Wang, Y. Azar, G. N. Wong, K. Wang, R. Mayzus, J. K. Schulz, H. Zhao, F. Gutierrez, D. Hwang, and T. S. Rappaport, 28 GHz propagation measurements for outdoor cellular communications using steerable beam antennas in New York City, in Communications (ICC), 2013 IEEE International Conference on, pp , June

10 mmwave for Mobile Broadband mmwave describes signals from 1mm to 10 mm (300 GHz to 30 GHz) Offers extreme bandwidths: up to 100 GHz of spectrum Substantially larger path loss & shorter signal propagation (< 500m) < 600 MHz spectrum in current cellular bands 100 GHz spectrum in milimeter wave bands 38 GHz GHz 28 GHz 60 GHz 300 MHz λ = 1m 3 GHz λ = 100 m 30 GHz λ = 10 mm 300 GHz λ = 1mm 10

11 NI and Nokia Demonstrate 10 Gbps at 73 GHz It took about 1 calendar year, less than half the time it would have taken with other tools Dr. Amitava Ghosh, Head of Broadband Wireless Innovation 11

12 Lowering Radio Cost with LTE-M Tx Rx Tx Rx 20 MHz 1.4 MHz 200 khz (Release 13) Half-Duplex FDD Operation Receive Bandwidth Reduction +23 dbm, 200 mw +20 dbm, 100 mw Rx 0 Rx 0 Cat-1 Cat-0 Lower Output Power Rx 1 Single Receive Chain Rx 1 13

13 NB-IoT Interoperability and Deployment Will be deployed in GSM and LTE bands (180 khz BW) NB-IoT should support 3 different modes of operation: 1. Operation in LTE guard bands (similar to RDS in FM bands) 2. In-band operation (utilizing normal LTE carrier) 3. Stand-alone operation, e.g. in GSM or LTE bands 20 MHz Allocated Channel 18 MHz Occupied Bandwidth 20 MHz Allocated Channel 18 MHz Occupied Bandwidth LTE NB-IoT LTE NB-IoT NB-IoT in LTE guardband NB-IoT within LTE band 14

16 What Changes from ad to ay? Wider Bandwidth More Spatial Streams Possible New Modulations 2.16 GHz (802.11ad) 4 GHz (802.11ay) 4 Streams 16 or 64 Streams 64-QAM 64-point NUC Wider bandwidth through the aggregation of more component carriers helps increase maximum data rate from 6.7 Gbps to 20 Gbps. More downlink antennas and spatial streams enables more effective beamforming and operation over longer distances. The potential use of non-uniform constellations eases linearity requirements on RF components and makes CMOS more realistic. 60 GHz Radio Front End 17
