2.3.2 RAU (Remote Access Unit)
The RAU distributes up to four RF services via internal antennas (external antennas are optional). The RF services are received
over optic cables and converted for distribution over internal (or optionally, external) antennas.
Figure 2-15. RAU Module Interfaces
Note: The RAU enclosure can host two additional modules: RxU for MIMO support (e.g. LTE700 and AWS) and GEM for digital
coverage. See relevant sections for details on these modules.
Interface Description
MGMT RJ-45 local management connection
PWR
DC power inputs
Main - connect to DC (from composite cable)
Secondary – in case of PoE clients. Used when GEM modules are installed
(in addition to Main)
F/O LC APC SM connectors for UL and DL optic connections
Listening Mode N/A
RF Filter (e.g. LTE, CELL) QMA RF ports for external cavity filter use (In/Out). For CELL and LTE filters.
External Antenna
Optional connection to broadband external antennas. Antenna must have a
return loss of 12dB. Requires GUI configuration (internal antenna is enabled
by default).
Grounding Bolt Location Use the 8-32X3/8 bolt (supplied with RAU) to connect RAU to earth ground
