FID-13019.36 introduces a Remote Radio Head (RRH) with an associated RET/ALD
controller that operates the RET.
The RET consists of an actuator motor with supporting control electronics. The RET
adjusts the antenna down-tilt angle by electrically changing the antenna phase angle. By
altering the phase of the antenna signal, the RET also tilts the antenna beam.. This results
in decreased main, side and backward lobes. This overcomes the shortcomings of
mechanical tilt antennas, where the whole antenna is physically tilted. This system moves
the backward lobe in upward direction and distorts the side-lobe patterns.
AISG interface on RRH
The RRHs are equipped with an Antenna Interface Standards Group (AISG) power and
signaling interface connector that supports third party Antenna Remote Electronic Tilt
(RET) equipment. The PCS RRH 4x and 800 MHz RRH 2x are hardware ready to
support the third party RET.
The following figure shows the 800 MHz/1900 MHz RRH configuration mounted on a
pole. The 800 MHz RRH is mounted directly above the 1900 MHz RRH. Each RRH is
equipped with a lifting handle. The antenna assembly is mounted opposite the RRHs.
Wall mounted RRHs
The following figure shows a typical RRH mounted on a wall with Unitstruts.
This section describes the only line-up that is available for the 9927 Distributed Base
Station Outdoor Cabinet.

Outdoor Cabinet and 60ECv2 battery cabinet when located side by side.
Anchoring footprint for 60ECv2 battery cabinet
The following diagram shows the 60ECv2 battery cabinet anchoring footprint required
for site preparation.
Important! Alcatel-Lucent does not provide support for RRHs that have been left
non-powered for an extended period of time and not stored in an environmentallycontrolled space. The Alcatel-Lucent Design Team provides the following guidelines
to minimize the build-up of moisture inside RRHs that must remain in the
non-powered state for an extended period of time.
This section describes how to properly store RRHs that have been delivered to an
installation site but have not been yet installed. The main concern with non-powered
cabinets is condensation inside the cabinet, which can result in corrosion or electrical
shorts. The location and length of storage time determine the severity of the problem.
These guidelines include prevention and drying steps.
Moisture problem prevention
To prevent moisture from collecting inside non-powered RRHs that are in storage, all
openings and connectors must be tightly sealed. The units should also be covered with a
waterproof tarp. The tarp should be sealed with duct tape. A desiccant packet should be
placed under the tarp to absorb moisture. The amount of desiccant is related to storage
time and to size of the unit. A visual check should be made to check for condensation
after uncovering the tarp.
Additional storage requirements
After performing the procedures above, ensure that the following steps are taken:
•The cabinet must be properly grounded.
•RF cables should not be connected to the RRH.
•Any connectors must be sealed with watertight plugs.
The following general requirements must be met before the installation of the RRH can
begin at the site:
•Adequate clearance must be provided for service access.
•Grounding electrode system must be installed.
•RF antenna runs must be installed .
•Tower light power must be installed (if required).
•Tower light alarm must be installed (if required).
•Cable supports must be installed.
Refer to Appendix A, “9927 Distributed Base Station Outdoor Cabinet site preparation
checklists” of this document for checklists of detailed requirements.
Structural requirements
Pole, wall loading, and wind must be considered during site preparation.
In some cases, cell site equipment may not be mounted directly to a wall without a plate
or Unistrut. A plate or Unistrut is necessary to properly distribute the weight of the RRHs.
The support structure must be in compliance with national building and other applicable
codes.
The following table provides the minimum wall mount clearances recommended around
RRHs.
