MIMO Configuration
In the MIMO configuration, the BIU expansion slots are filled with another set of frequency modules and a
combiner which provides the MIMO capability. The two combiners each feed their own Express ODU -
shown here as an Orange "Leg A" and a Blue "Leg B." Two strands of fiber connect the respective
MRU/ARU combinations and their attached antennas through coaxial cable.

VHF/UHF Support
Support for VHF/UHF allows the EXPRESS DAS to host Public Safety and 2-Way Radio communications
used by fire, police and first responders. The VHF/UHF capability is built in to the BIU, so offering support
for these services does not require adding frequency modules or using additional expansion slots.
However, a special VHF/UHF add-on remote unit is required to support these bands.
