2 Introduction

2 INTRODUCTION

2.1 PURPOSE

Wireless communication systems provide a two-way information transfer (voice and
data) between a base station and multiple mobiles within a given area.

Environmental variables such as physical structures both man-made (buildings) and
natural (mountains) attenuate signals in the transmission path, which reduce the
transport signal’s strength. This attenuation leads to a reduction in quality and data
rate and eventually prohibits the system’s use entirely. A Node C is specifically
designed to extend coverage, enhance quality, and increase air-interface capacity.

In the downlink (DL), the Node C picks up signals coming from the base station,
filters them, amplifies them, and retransmits them to the mobile. In the uplink (UL), it
picks up signals from the mobile, filters them, amplifies them, and retransmits them to
the base station. The Node C constantly monitors the quality of the signals passing
through it, while simultaneously electronically decreasing isolation requirements.

2.2 THE NODE C NETWORK ELEMENT

The Node C is a primary network element, capable of enhancing up to three adjacent
CDMA carriers in a CDMA system. Its primary function is to increase the signal
strength between multiple mobiles and a base station in areas where basic voice or
high-speed data transmission is not available. It may be used for basic coverage,
signal reinforcement, and cell shaping, which can increase a network’s coverage
area, data rate, and capacity.

The Node C is a dedicated CDMA device. However, several enhancers operating at
different frequencies and technologies may share the same hardware (cables and
antennas) via a crossband coupler. Within the CDMA frequency band, multiple
operators may use the same unit via additional modules, thus reducing cost, while
sharing the user interface and antennas.

The Node C may be set-up locally or remotely. A circuit switch or packet data modem
may be connected to an integrated controller. This provides the network
management system with on-demand, alarm generated, or heartbeat monitoring via
the always-connected packet features. The Node C has features and functions that
may be monitored and changed by the operators via a web-based browser remotely
or locally, or via the SNMP based OMC software platform. The graphical interface of
the Node C provides a setup menu including a setup wizard which allows both setup
and monitoring capability without any equipment required apart from a laptop or PC.

The Node C network element is self-diagnosing, self-adaptive, and virtually
maintenance-free.

3 INSTALLATION

3.1 MECHANICAL INSTALLATION

3.1.1 General

Read the health and safety warnings in chapter 1.2 Health and Safety Warnings.

1. Do not install the unit in a way or at a place where the specifications
outlined in the Environmental and Safety Specifications leaflet of the
manufacturer are not met.

2. It is recommended only to use the mounting hardware delivered by the
manufacturer. If different mounting hardware is used, the specifications
for stationary use of the unit must not be exceeded.

) Note: Exceeding the specified load limits may cause the loss of warranty.

3. The unit is considerably heavy. Make sure that a suitable mounting
surface is used. Ensure there is adequate manpower to handle the
weight of the system.

4. Due to power dissipation, the unit may reach a very high temperature.
Ensure sufficient airflow for ventilation. Above and below the units a
minimum distance of 300* mm to ceiling, floor, etc. has to be kept. This
distance must also be observed between two units if they are mounted
one above the other.

* This value does not apply to the distance between Interface Unit and Node C. The

distance required between the two cabinets is specified in table 3-1 Mounting distance.

If any different or additional mounting material is used, ensure that the mounting
remains as safe as the mounting designed by the manufacturer. Ensure that the
static and dynamic strengths are adequate for the environmental conditions of the
site. The mounting itself must not vibrate, swing or move in any way that might cause
damage to the unit.

) Note: Both the Node C and the Interface Unit are delivered with a pre-

mounted front cover. This cover is of vital importance for the
correct forced airflow (of Node C 43) and for passive cooling (of
Node C 37 and Interface Unit). Thus, do not operate the units
without cover.

User’s Manual for Node C Network Elements

3.1.2 Wall Mounting Procedure

• Check the wall mounting kit and the wall to determine their suitability.

• The maximum distance between the Node C and the Interface Unit depends on

the length of the cable bridge (standard length is 500 mm) by which they will be
connected (see table 3-1 Mounting distance). Thus, before marking the mounting
positions, check the length of the cable bridge and make sure to install the units
at a suitable distance.

Mounting style: beside each other* one above the other**
Length of cable bridge: 500 mm 800 mm 2000 mm only 2000 mm possible
Maximum distance 140 mm 400 mm 1600 mm 1000 mm (min.=300 mm)

* Maximum distance is referring to distance between the cabinet sides
** It is recommended to install the Node C above the

between top of lower and bottom of upper unit

Interface Unit; max. distance is the distance

table 3-1 Mounting distance

) Note: The following figures show units that are mounted beside each

other. To install one above the other proceed in the same way, also
observing the specified mounting distance from table 3-1.

• Mark the position of the eight drilling holes (four per unit) for the Node C and
Interface Unit according to figure 3-1. Please observe that the figure always
shows a pair of drill holes for each position. Only drill one of each pair.

Page 14

figure 3-1 Positions of drilling holes

M0121A1A_uc.doc

3 Installation

) Note: Ensure that there is free access to the electrical connections as well

as to the cabinet. The approved bending radius of the connected
cables must not be exceeded.

• Drill eight holes (four per unit) at the marked positions and insert dowels*.

* The dowels are not part of the delivery (and thus not illustrated in the figure) since the suitable type

depends on the on-site conditions (the material of wall). Therefore, use dowels that are appropriate
for the mounting surface.

• Use a cap nut or locknut to screw the eight M8 dowel screws into the dowels.

• Use a hex wrench, opening 17 (old standard) or 16 (new standard), to loosen the

M10 hexagon head screws (four per unit) by which the mounting brackets are
fastened to the cabinet sides.

• Mount the mounting brackets to the screws, and fasten them using the M8
washers, locking rings, and hex nuts that are part of the wall mounting kit.

• Hang the cabinets into the brackets and fasten them with the M10 hexagon head
screws*.

grounding bolt is provided on the cabinet to connect the ground bonding
cable.

3. Although the unit is internally protected against overvoltage, it is

strongly recommended to earth the antenna cables close to the unit’s
antenna connectors for protection against atmospheric discharge. In
areas with strong lightning it is strongly recommended to insert
additional lightning protection.

User’s Manual for Node C Network Elements

4. Hard wired installation of mains supply for the unit requires an easily

accessible separation device in the mains circuit.

5. Make sure that an appropriate circuit breaker and an overcurrent limiting

device are connected between mains and the unit.

6. A connection of mains supply to a power socket requires the power

socket to be nearby the unit.

7. The unit might be supplied from IT mains. (The maximum nominal line to

line voltage must not exceed 400VAC).

8. Incorrectly wired connections can destroy electrical and electronic

components.

9. To avoid corrosion at the connectors caused by electrochemical

processes, the material of the cable connectors must not cause a higher
potential difference than 0.6V (see electrochemical contact series).

10. It is sufficient to tighten the 7/16 or N antenna connector hand-screw ed.

Any use of a tool (e.g. pair of pliers) might cause damage to the
connector and thus lead to malfunctioning of the unit.

11. For unstabilized electric networks which frequently generate spikes, it is

advised to use a voltage limiting device.

12. The unit complies with the surge requirement according to EN 61000-4-5

(fine protection), however, it is recommended to install an additional
medium (via local supply connection) and/or coarse protection (external
surge protection) depending on the individual application in order to
avoid damage caused by overcurrent.

13. Observe the labels on the front panels before connecting any cables.

3.2.3 Power Connection

Before connecting electrical power to the units, the system must be grounded as
described in the previous chapter.

Mains power must be connected at the mains connector of the Interface Unit. The
power supply plug is included with the Node C.

The correct wiring
of the power supply
plug is as follows:

User’s Manual for Node C Network Elements

Mains

figure 3-10 Power supply plug figure 3-11 Mains connector

A minimum cross section of 1.5 mm2 is required for the power supply

connection. Each wire must observe the applicable national regulations
regarding loop impedance, voltage drop, and methods of installation.
Make sure to connect the correct voltage to the unit.

) Note: Do not connect or disconnect the power cord at the mains connector

while power is on. Turn off mains* power before connecting the
power cord at the Interface Unit, then, engage mains again.

* Mains power must be interrupted with an external AC breaker. For the AC breaker,
observe the following recommendation:

120 Volt / 20 Amp max. or 240 Volt / 16 Amp, single-phase, 50/60 Hz AC service is
needed, i.e. the external AC breaker should be 20 Amps max. for 120-Volt service or
16 Amps for 240-Volt service.

3.2.4 Connection of the Antenna Cables

The Node C’s antenna connectors are 7/16 female equipped with an N female
adapter. All connectors are located at the bottom of the cabinet. An operator should
refer to the documentation of the cable connector manufacturer for best mating
procedures. Furthermore, the bending radius of the antenna cables should be
maintained at all times.

There are several issues to be considered when selecting the cable and antenna
types.

• Smaller diameter cables are less expensive and easier to install but have

worse performance.

• Highly directional antennas with good front-back-ratios (40 dB is typical) are

recommended because they improve isolation and cell site selectivity.
Tighten the 7/16 or N connectors ONLY by hand. The use of pliers may cause

damage to the connector and impair the performance of the Node C.
