<div dir="ltr">That distance matrices manage energy between nodes. The slides show a 5 branch tree to realize 4 nodes (and that distance matrix) and a diagram for 11 degrees of freedom for 6 nodes (3 BSS) The python code will compute the branch attenuations based on a supplied distance matrix. There will of course be some distance matrices that cannot be achieved per the reduction of the degrees of freedom required to realize this using physical devices in a cost effective manner.<br><br>Bob</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Aug 2, 2021 at 4:16 PM David Lang <<a href="mailto:david@lang.hm">david@lang.hm</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">If you are going to setup a test environment for wifi, you need to include the <br>
