• RRH mounting kits in assembled installation mode are not allowed in indoor
scenarios.
g Note: If the RRH is improperly installed, heat dissipation of the RRH deteriorates and
the RRH may not work properly, as shown in Figure 4: Improperly installed RRHs.
Figure 4 Improperly installed RRHs
Method of installation:
• If an AC RRH consists of a 18 L blade RRH and an OPM15M, this AC RRH cannot
be installed in side-mounted mode.
• To ensure the heat dissipation of the RRH and waterproofing of the ports at the
bottom of the RRH, the vertical deviation angle of an RRH must be less than or equal
to 10 degrees, as shown in Figure 5: Requirements for the vertical deviation angle of
an RRH.
• On a tower, an RRH can be installed on a pole, angle steel, or U-steel. The side-
mounted installation mode (one side instead of the rear of an RRH is mounted on the
support) is recommended for RRHs on the main pole secured on a tower. This
installation mode allows multiple RRHs to be installed next to each other at the same
level on a pole. When the horizontal distance between the main and auxiliary poles
on a tower is equal to or greater than 810 mm (23.62 in.), the side-mounted mode is
recommended for installing RRHs on the auxiliary pole to meet the minimum
clearance requirements. Otherwise, the standard mode is recommended for
installing RRHs on the auxiliary pole.

7 Antenna requirements
This chapter provides an overview of the antenna interface requirements for B31
RRH2x40.
7.1 Antenna requirements

The customer is responsible for providing the materials and arranging for the installation
of the entire RF path from the antennas to the B31 RRH2x40 RF connectors. This may
involve long tower runs of large gauge heliax type cable and a transition to jumper cables
at one or both ends if the B31 RRH2x40 RF is mounted at the base of the tower.
If the B31 RRH2x40 RF is mounted at the top of the tower or on a roof top installation,
the antennas may be adjacent to the RRH unit such that there is only a short RF coaxial
jumper run, with no other transitions. These RF cable installations may also require RF
cable grounding, surge protection, and additional equipment in the RF path for sealing,
air evacuation, or connectivity. The RF cable installation also may require additional
mechanical support brackets, clamps, and structures from the antennas at the top, down
to the location of the RRH installation.
The customer is responsible for the long run RF cables and the RF jumper cables that
connect to the RF connectors of the B31 RRH2x40.
Requirements to support location-based services

All of the requirements that follow in this topic apply if the customer intends to support
location-based services. The antennas referred to here are those for the main RF paths
for a single sector.
In order to support location-based services, the antenna location and the type and the
length of antenna cables must be provided for use in calibration.
These values must be determined and recorded during site preparation.
7.2 RF antenna requirements

RF antenna connections
The B31 RRH2x40 has two RF antenna connectors. The RF antenna connectors are
7/16 DIN female.

LTE B31 RRH2x40 (UHAA) Site Preparation Guidelines AISG interface requirements
10 AISG interface requirements

This chapter provides the AISG interface requirements for the B31 RRH2x40.
10.1 AISG cable requirements

AISG Multi-Wire Cable
An RRH AISG multi-wire cable connects an RRH to a RET-equipped antenna to transmit
control signals from a base station to a RET-equipped antenna. When the RRH is
connected to the RET-equipped antenna, an AISG multi-wire cable transmits RS485
signals. The length of the AISG multi-wire cable is 5 m (16.40 ft).
g Note: An RRH is a driving motor used for the phase shifter in the RET antenna. It
receives control commands from a base station and runs the commands to drive the
stepper motor. Using a gear, the stepper motor drives the adjustable phase shifter in the
antenna and changes the downtilt angle.
An AISG multi-wire cable has a waterproofed DB9 male connector at one end and a
standard AISG female connector at the other end, as shown in the following figure.
Figure 43 AISG multi-wire cable
The following table describes the pin assignments for the AISG multi-wire cable.

AISG Extension Cable

When the distance between an RRH and a RET-equipped antenna is longer than 5 m
(16.4 ft), an AISG multi-wire cable is not long enough to connect the RRH and a RET-
equipped antenna. In this case, a AISG extension cable is used to extend the AISG
multi-wire cable for transmitting RS485 signals. The length of the AISG extension cable
can be 1, 2, 5, or 10m.
An AISG extension cable has a standard AISG male connector at one end and a
standard AISG female connector at the other end, as shown in the following figure.

-48 VDC power systems
13 Appendix: Electrical power requirements for

3rd party -48 VDC power systems
The purpose of this appendix is to provide power requirements for the radio equipment
RRH, in case a 3rd party power system is used.
IMPORTANT: All AC wiring and over-current protection must be installed in accordance
with the National Electric Code (NFPA-70) and local electrical codes. An appropriate
earth ground connection is required before commercial AC service can be connected to
any equipment at the site.
13.1 Power requirements (general)

Scope
This section specifies the DC power and power system alarm interface requirements for
the RRH equipment. Specifically DC power, DC feeder quantity, recommended DC
feeder wire gauge, and DC feeder circuit breaker type/rating. Some additional
information is included on power feeder connections and alarm connections to the RRH.
This section provides information on the quality and characteristics of the DC power to
be supplied to the RRH.
The power systems must provide uninterrupted DC power to the RRH. In the event of
loss of AC input power, the power system must continue to provide DC power for the
duration of the battery reserve.
The power system must be designed to support a fully configured site that consists of the
following: Two carrier, six sector configuration with up to two BBUs and up to six RRHs.
Designing a system that cannot support the fully configured system will limit the potential
for future growth. This section is intended for use by a customer specifying a power
system other than the standard company power systems.
By meeting these requirements, the equipment referenced in this section should meet
the electrical and RF performance specifications of the customer supplied equipment.
Standard reference document

The company strongly recommends that the power system meet all applicable
requirements specified in the following documents. The appropriate requirements must
be selected from the documents listed in the table below, based on the "country of use."
In addition, adherence to all additional requirements mandated by the "country of use" is
the customer's responsibility. The power system must meet the specified UL and FCC
requirement documents in order for the equipment to maintain its UL and FCC
compliance. The references listed in the table may be obtained from the issuing agency
or their authorized distributors.

Transient load response

For any step-load demand change of 10% to 90%, or 90% to 10%, on the DC power
system, the DC input voltage to the RRH shall remain within 5.0% and return to the 0.5%
regulation band within 300 milliseconds.
Backup power requirements

In the event of a commercial power failure, the company recommends the DC power
provided to the RRH be backed up for a minimum of 30 minutes. The DC power to the
equipment shall not be interrupted during the transition from normal operation to backup
operation and vice versa.
w If the DC power supplied to the RRH is not equipped with backup power, undesirable
performance may be experienced during interruption and/or transients to the AC input
power.
High voltage shutdown

The DC power source may shut down if the output voltage reach the following values:
RRH Maximum voltage range(Volts DC) Maximum voltage for up to one second
-48V DC -56.2 to -60 -60
DN09249148 Issue: 04 © 2018 Nokia 89

The DC power system shall not provide sustained voltage to the RRH at the maximum
voltage values, for more than one second, as shown in the table above. If a power
system failure occurs which causes loss of regulation resulting in voltage levels given in
the table above stated as the "maximum voltage range", the power system shall
shutdown or clamp its output voltage below -56.2 V DC (for -48 V DC systems) until the
problem is corrected.
Transient surge protection

The DC power system shall be designed to prevent surge transients at its input passing
through to the output and causing voltage transient in excess of -60 Volts (for -48 V DC
systems) to the RRH. Adequate transient surge protection shall be provided for the DC
feeders by running the feeders from the power system to equipment inside properly
grounded metallic conduit. In addition, surge protectors and/or surge suppressors may
be required to limit surge voltages to less than -60 Volts (for -48 V DC systems). If
external surge protection is required to meet this limit, it should be installed near the DC
input terminal of the RRH.
DC power grounding
The -48 V DC return conductors shall be bonded to the frame ground system at the
output of the DC power system. For proper site grounding of the equipment, refer to
"Grounding and Lightning Protection Guidelines for Lucent Technologies Network
Wireless System Cell Sites", number 401-200-115.
