英文学术报告 Taking 5G form Vision to Reality 姓名:xx 班级:xx 学号:xx At the beginning of the lecture introduces the establishment of Keysight Technologies company development Agenda: Review of major innovations in wireless communications 2. UMTS long term evolution 3. The motivation and vision for 5G 4. 5G technical assumptions Six predictions for broadband wireless 2020 6. Summary 5G overview Expectations,opportunities,major players and timing 5G requirements framework What do we need for 5G to be successful? ① we need a bold vision that the vision must obey the laws of physics ② For an industry to be mature requires ③ successful industry also has to be sustainable Enabling Technologies and measurement challenges Understanding cellular performance speed versus capacity the problem of handover variation of performance across area variation of throughput across a cell in a loaded network maximizing capacity in a given area Exploiting the spatial domain at mmWave a cellular network capacity modal adding cell co-location or massive MIMO increasing mmWave capacity with massive MIMO system VUE tool modeling large numbers of antennas New modulation formats 1G---FM 2G---GMSK/CDMA 3G---W-CDMA 4G---OFDMA SC-FDMA 5G---NIMA FBMC performance analysis analyzing the impact of real hardware selecting between simulated and real hardware analysis properties of the simulate signal in the VSA impaired properties of the signal form a typical UE PA applying signal conditioning Working with wideband signals at mmWave Spectrum aspects Business considerations The unprecedented interest and investment in the next generation needs to be matched to viable business cases to ensure sustainability Six predictions for wireless broadband 2020 No new worldwide allocations of mmWave spectrum Cellular will extend into the ISM band at 60 GHz (Unlicensed access) The importance of UE antennas will finally be recognized WLAN will become an equal part
