5.2.2 RAU Installation
5.2.2.1 General Information
1. The RAU modules are deployed on the floor level and interface to the RF antennas.
2. The RAU can be provided in a number of configurations:
RAU alone (without RxU and GEM); weight = 7.93 lbs (3.6 kg)
RAU + RxU
RAU + GEM
RAU + RxU + GEM; weight = 12.12 lbs (5.5 kg)
Note: Existing RAU units can be upgraded with RxU (for MIMO support) and/or GEM modules (for Ethernet services) see
Appendix A for instructions on how to upgrade the RAU with these modules.
3. The RAU supports various mounting installation options:
Wall-mount installations (vertical); required ambient temperature of 45
C [113
F]
Ceiling-mount installations (horizontal): required ambient temperature of 45
C 50
C [122
F]
Note: If the RAU is installed below or mid-mount an acoustic ceiling, a support bar (T-Bar) is required (not included).
Acoustical ceiling grid work is not designed to support the weight of the enclosure.
4. The RAU unit is provided with a mounting bracket used for mounting on the wall or concrete ceilings (including above
acoustic ceiling mounts). Additional below/mid-mount acoustic ceiling mounting options are possible using a T-Bar mounting
bracket (not provided).
5. RAU optic fiber connections and DC power are provided via a Corning Composite cable (ordered separately).
6. External cavity filters (AK-CVT700; AK-CVT800) are required for installations in which RAU/RXU modules supporting the
corresponding CELL and LTE bands are deployed alongside units supporting the public safety service. See section 5.2.3 for
installation instructions.
