3.1. SISO and MIMO Operation
The architecture of the ION-U low power supports both SISO and MIMO operation.
MIMO operation is achieved by pairing two RUs.
The following figures show views of a single Remote Unit for SISO applications and
two Remote Units paired for MIMO applications.

The ION-U EU L 23/23 Extension unit with integrated antenna port combiner together
with ION-U L 7/80-85/17P/19P allows for further options.
