A vertically interleaved in-building distributed antenna system is described. The in-building distributed antenna system includes a multiple-input and multiple-output (MIMO) radio. The MIMO radio includes a first branch connector and a second branch connector. The in-building distributed antenna system further includes a first branch transport medium coupled to the first branch connector and a second branch transport medium coupled to the second branch connector. The in-building distributed antenna system further includes a plurality of antennas. The plurality of antennas includes one or more first branch antennas coupled to the first branch transport medium and one or more second branch antennas coupled to the second branch transport medium. The first branch antennas are vertically interleaved with the second branch antennas in the structure.
