This document describes the AIR 6488 unit. How Much Performance is Lost by FDD Operation? That would mean this concept is also more cost efficient, because each subarray can be adapted to a certain enviroment such as urban, rural etc.. For example, in rural areas the subarray will have a narrower beam created by more antenna elements (e.g.8AE ) and in an urban area the vertical-beam would be less narrower (e.g.4 AE) known as angular coverage. Five years ago, when I wrote the book Massive MIMO Networks, I had the vision that we should eventually be able to squeeze all the components into a compact box with a size that matches the antenna array dimensions. 2 external alarm. <> Is my understanding correct?
