5G means business. With wired speeds coming in over the air, designers are turning to new wireless techniques like beamforming, MIMO, and advanced tower synchonization designed to pump you full of bits. Find out more as Daniel Bogdanoff sits down with Brig Asay and Joe Haver to discuss the changing wireless ecosystem of tomorrow. Audio: Video: https://www.youtube.com/watch?v=XX0r22fSBwI 1:00 4G was sub 6 GHz, but 5G is much higher frequencies (24 GHz, 28 GHz, 39 GHz, and above 50 GHz) 2:15 4G test strategies: simple source and a middle-of-the-line signal analyzer. There were also some combo boxes that were both signal sources and signal analyzers. 4:00 5G testing requires more powerful setups. There are still generators, but they have to be more powerful. FR2, 100 MHz, 200 MHz, 400 MHz wide bands make things more complicated. Chambers and OTA (over the air) testing and MIMO systems make things much more complicated. And, a 5G system has to cover all of these ranges. 5:30 MIMO for 5G...
