This year I have a special interest in 5G communications. Frequent readers of Test Cafe blog know that I have recently written about 5G, and why modular instruments are well positioned architecturally to address the challenges of 5G. Architecturally yes, but without the mmWave (millimeter wave) instruments needed for the highest frequency 5G microwave bands. My most recent column made an unequivocal prediction: We will see modular microwave, and mmWave in particular, within 18 months. That is, by the end of 2016.
Perhaps I should have said 18 days.
As part of the Day 2 Keynote presentation at NIWeek, Nokia and NI demonstrated a “5G” 10Gb/s wireless link operating at 73GHz, architecturally based on PXI and LabView. For completeness, I should mention that Keysight Technologies had just announced a 5G channel sounding reference system, based on PXI and AXIe, a week earlier. I should have bought a lottery ticket the day I made that prediction! I hope to cover the Keysight system in a subsequent column. Today I will focus on the Nokia/NI system.
You won’t find any press releases or data sheets about the NI products behind the Nokia system. They are yet to be released as generally available products. However, NI was more than happy to showcase the system and describe how it operates.
So, as another Test Cafe exclusive, here’s the inside view of how the system is architected…
