1 Massive testbed: Validation SEFFEN MALKOWSKY, LUND UNIVERSIY, SWEDEN
2 Why do we need a testbed? Ø heoretical results show that massive has very promising features for future wireless generation, however they cannot answer all questions: 1) How does it perform under real-life conditions? 2) How can we model massive channels? 3) Implementation challenges/issues? 4) Required reciprocity calibration accuracy? 5) Is pilot contamination a problem? 2
