Some Quest stions s fo for Discu scussi ssion • Devices es and Materi erials: – What are prospects for large-signal network analysis at mmWave frequencies? – What are issues tuning mmWave harmonics? – What is the role of materials measurements in future wireless? • Signal characteri erization on: – How to handle issues with cascading non-ideal, distortion-inducing instruments (similar to Additive EVM)? – How do you see the role of traceability in waveform measurements? Channel el mea easurem emen ents: • – Why is it more important to decouple the antenna from the channel measurement? – Will errors in channel sounders be more important at mmWave frequencies? • Anten ennas and Massive e MIMO: O: – How does one generate a known test field for multiple-element antenna arrays? – What is the role of statistics in testing arrays that operate in more states than you can count? – What are issues with distributed array timing and synchronization? The e Elep ephant in the e Room oom: • – How to merge on-wafer and OTA test to verify performance? 7 5G-<LastName>
