Module Description
External Antenna
RF Connection to external antenna, used for above-ceiling installation.
Antenna must have a return loss of 12 dB.
(Both the RxU and the RAU antennas are used since this implements a
MIMO configuration)
External RF Filters
QMA RF ports for external cavity filter use (if required by site planner). For
CELL and LTE filters.
RUN LED Indicates SW is up and running.
