On conducted topologies, here are two common ones where ln are variable
attenuator legs. The asterisk is a butler matrix or splitter/combiner in
the relative center.
l1\ / l2
Then the power levels are controlled by variable attenuator legs, giving 4
degrees of freedom.
l1\ / l2
This immediate above collapses to the star when l5 = 0. Otherwise l5
separates two BSSIDs as an example.
The matrices are simple, eg. for the star:
1 1 0 0
1 0 1 0
0 0 1 1
0 1 0 1
