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.

3.1 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:
3.
Exceeding the specified load limits may cause the loss of warranty.
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 premounted 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.

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 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:
Length of cable bridge:
Maximum distance
beside each other*
500 mm 800 mm 2000 mm
140 mm 400 mm 1600 mm
one above the other**
only 2000 mm possible
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 Interface Unit; max. distance is the distance
between top of lower and bottom of upper unit
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.

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*.

3.2 ELECTRICAL INSTALLATION
3.2.1
General
Read the health and safety warnings in chapter 1.2 Health and Safety Warnings.
1. This unit contains dangerous voltages. Loss of life, severe personal
injury or property damage can be the result if the instructions contained
in this manual are not followed.
2. It is compulsory to ground the unit before connecting power supply. A
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.
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-screwed.
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.

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:
Mains
figure 3-10 Power supply plug
figure 3-11 Mains connector
A minimum cross section of 1.5 mm2 is required for the powersupply
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 (N female is an option). All
connectors are located at the bottom of the cabinet. An operator should refer to the
cable connectors manufacturer’s documentation 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.

Connection of Cable Bridge
The Interface Unit and the Node C are connected via a cable bridge. The bridge
ports 12V, 28V, ground, USB, and RS232 between the two units as well as the
general alarming and signalling. It is also the interconnection and intercommunication
bus between the units.

b) Typical Tuning Procedure (See example table below):
1. Point the donor antenna in the general direction of the donor base station.
2. Start the AAA.
3. Verify that the reported DL Rx Power is above –90dBm. If not, orient the antenna
until the signal is above –90dBm.
4. Wait for Pilot RSCP results to be reported (indicating that a valid pilot has been
found).
5. Verify that the ARFCN and frequency reported at the top of the table matches the
ARFCN and frequency of the donor base station.
6. Orient the antenna to maximize the Pilot RSCP from the donor base station.
Usually, the best method is to course-tune the antenna based on DL Rx Power
measurements and then fine-tune based on Pilot RSCP measurements.
However, if multiple pilots are present, then using the DL Rx Power
measurements alone may not work well, and the user will have to rely on Pilot
RSCP only.
7. If multiple rays are present, then it is usually best to orient the antenna to
maximize the level of the first ray (the line-of-sight – or LOS – signal). However, if
the first ray is not the strongest signal, then there is an obstruction in the LOS
signal, and the strongest signal is a multipath component. This may mean that the
donor signal is prone to fluctuation, resulting in sub-optimal performance of the
unit.

c) Notes on the AAA Measurement Results:
1. The DL RX Power is the total power in the selected 5 MHz channel. The DL Rx
Power measurement is updated approximately once per second.
2. The Pilot Received Signal Code Power (RSCP) measurements are updated
approximately once every four seconds after the antenna assistant finds a valid
pilot channel within the selected 5MHz bandwidth. It may take up to one minute to
perform the initial scan and report Pilot RSCP results.
3. The most recent results are displayed in the first row, and previous results move
down one row in the table.
4. Data is columnized based on the most recent pilot measurement results.
5. The pilot measurements display up to the four strongest rays. The measurement
result could show one pilot with four rays, two pilots with two rays each, one pilot
with three rays and one pilot with one ray, or four pilots with one ray each (or
fewest results if no additional pilots are found).
6. Multiple rays of the same pilot will be shown if the weaker rays are within 10dB of
the strongest ray.
7. The Pilot RSCP data is sorted based on the total power of all multipaths for each
particular scramble code. For instance, if one pilot has two rays, each at –63dBm
(for a total power of -60 dBm), they will be listed first if all other pilots are less than
-60 dBm.
8. If two or more multipath signals are received, then the power of each ray will be
displayed in order of arrival. The first ray is the line of sight signal and should be
the strongest. However, it is possible for the later rays to be stronger.

The following figure shows the RF block diagram of the Node C.
figure 5-2 Configuration of a Node C network element
The Node C is designed to amplify signals between multiple mobiles and a base
station in a CDMA system. The unit consists of a filter and amplifier chain in the
downlink and one or two filters and amplifier chains in the uplink (primary and
diversity). The uplink and downlink paths are connected via a duplexer on both ends
of each path.
Page 70
PRELIMINARY
M0121A1A_uc.doc
5 Functional Description
In the primary uplink path, a signal originating from the mobile is separated from the
downlink signal via the primary UL IN duplexer. It is then amplified by an integrated
low noise amplifier (LNA) and forwarded to the uplink digital channel module (DCM).
The DCM down-converts the signal to base-band, digitally filters it, amplifies it and
then up-converts it. In addition the interference cancellation technology is
implemented in the DCM. Finally, the signal is sent to the final amplifier and
combined with the downlink input signal in the DL IN duplexer. The optional diversity
uplink path (via a second filter) is identical except signals enter via the diversity UL IN
duplexer and are combined in the DCM with the primary path.
In the downlink path, a signal originating from the base station is separated from the
uplink signal in the DL IN duplexer. It is then amplified by an integrated low noise
amplifier (LNA) and forwarded to the downlink digital channel module (DCM). The
DCM down-converts the signal to base-band, digitally filters it amplifies it and then
up-converts it. In addition the interference cancellation technology is implemented in
the DCM. Finally, the signal is sent to the final amplifier and combined with the uplink
input signal in the primary UL IN duplexer. The downlink DCM is also responsible for
communication and control of the entire unit. Using a Node C 1943 as an example,
the following figure illustrates the positions of the RF components inside the Node C.

5.2.2 Digital ICE (Digital Interference Cancellation Equipment)
Digital ICE has been developed to enhance antenna isolation. This feature enables
the Node C to provide coverage in areas where effectivity is decreased due to
physical site limitations which cause insufficient antenna isolation.
Antenna isolation is the RF loss measured between the donor antenna and the
coverage antenna. If the gain of the network element exceeds the path loss,
feedback in form of oscillation occurs. The isolation is usually dominated by the direct
path loss from one antenna to the other, but reflections can contribute to or even
affect antenna isolation. Digital ICE cancels the signal from the primary feedback
path, thus allowing the gain of the network element to be increased.
The required delay resulting from the on-site conditions is measured by the DCM
module and set accordingly.
For software setting commands please refer to the online help screens.
The Digital ICE function can be enabled or disabled in the “Technician Setup” page
(see chapter 4.2.4.3). Isolation and gain margin* can be checked in the “Status and
Reports” menu accessible via the home page of the web interface (see figure 4-4).
* gain margin = antenna isolation minus Node C gain

5.2.3 VSWR (Voltage Standing Wave Ratio)
This feature enables the provider to query the status of the antenna system (antenna
& cable). The voltage standing wave ratio of the DL output antenna port is measured.
If the VSWR falls below the value set in the “Alarming Management” (see chapter
4.2.4.4), an alarm is released. The alarm can be forwarded to the OMC where the
faults and irregularities can be acknowledged and eliminated promptly.
The current VSWR value can be checked in the “Status and Reports” menu
accessible via the home page of the web interface (see figure 4-4).
5.2.4 RSSI (Receive Signal Strength Indication)
The RSSI provides controlling and monitoring of the receive level of a base station
(DL RSSI) or user equipment (UL RSSI) to a Node C. It measures the level of the
input signal by detecting the RF and converting the analogue level into a digital
value. The data are processed and evaluated by software. An alarm will be released
if the measured signal level exceeds the alarm level set by the provider via software.
) Note:
If the Node C is equipped with a diversity path, both values will be
combined before the RSSI evaluation. Thus, only one UL value is
reported.
The current RSSI values can be checked in the “Status and Reports” menu
accessible via the home page of the web interface (see figure 4-4).
5.2.5 Alarmforwarding
Alarms can be forwarded to a defined phone number or to the OMC if the Node C is
equipped with a modem or a mobile station. This enables the provider to control and
to query the status of the network. Faults and irregularities can be recognized and
eliminated.
With an optional modem the Node C also provides an SMS feature, by which the unit
is able to send out alarm messages as SMS. For further details please contact your
supplier.

Duplexer
The duplexer is used to isolate the uplink from the downlink, i.e. to separate the
transmitting path from the receiving path. The pass band of the duplexer is the full 60
MHz of the CDMA band. This allows the same Node C to be used regardless of its
operator’s frequency plan.
The integrated LNAs (low noise amplifiers) are biased via the RF cable from the
DCM module. The DL/LNA can be bypassed for strong input signals by the DCM
module automatically.

Digital Channel Module (DCM)
The task of the digital channel module (DCM) is to filter and amplify any signals
passing through it. In addition it takes measurements of the input and output signals
and decodes the air interface to ensure proper setup and operation.
Finally it performs the interference cancellation algorithms, which eliminate the
normal problems associated with isolation, and has an integrated controller (in the DL
part) for the entire Node C, which maintains a web server for local and remote
communication. This process is accomplished by both analogue and digital means.
In case the diversity option is equipped, the module receives signals from both the
primary duplexer and diversity filter. Both signals are combined digitally and filtered
before being amplified in the uplink amplifier.
The DCM consists of an UL and DL part.

Battery Backup
In case power fails, a battery backup system for controller and modem has been
implemented. This provides enough power for the controller that is integrated into the
downlink DCM and the modem to operate for a limited period of time (see chapter
7.2.3 Specifications for Optional Equipment for battery backup time). Within this time,
the Node C will initiate a call to the OMC and alert the operator that power has been
lost. All other functions will cease to work in case of power failure.
The battery packs are protected from deep discharge by use of a low voltage
disconnect unit. When performing preventive maintenance, make sure that all circuits
are voltage free by disconnecting the battery cable (C1) from its connector (C2). In
case of a power cycle, it is sufficient to press the “Battery disconnect button” to
interrupt the voltage supply. After mains is connected again, the battery will be
charged and the battery backup function will be activated automatically.

The battery pack should be discharged at regular intervals of about three months to
optimize its service life. This service discharge may be activated via software
depending on the software version. The time required for the discharge varies
depending e.g. on the charge status of the battery pack. A fully charged battery may
require up to some hours to be completely discharged. Consider this when activating
the discharge and also observe the following note.
) Note:
Please be aware that the backup function is not available during
discharge. Thus, a primary voltage failure in that time will result in
a complete system shut-down.
It is recommended to replace the battery pack of the battery backup option after two
years of usage as a preventive measure. The nominal lifetime of the battery pack is
approx. two years under normal environmental conditions.

6.2 REPLACEMENT OF COMPONENTS
Read the health and safety warnings in chapter 1.2 Health and Safety Warnings.
Maintenance of the Node C should be performed on a FRU (Field Replaceable Unit)
basis only. Do not damage the warranty labels on the components, as this voids the
warranty.
The spare parts list contains only units that can be replaced without tuning or
complex soldering work. Those units are all components of the Interface Unit. Do not
replace any components inside the Node C itself.
) Note:
Defect parts should only be replaced by original parts from the
supplier. All interventions inside the housing are at one’s own risk.
) Note:
During maintenance ensure that the unit has been disconnected
from mains.
To open the cabinet of the Interface Unit, observe the instructions in chapter 4.1
General.
) Note:
If the optional battery backup is installed, disconnect the battery
cable from the charge module connector as described in chapter
5.4.1.3 Battery Backup, to ensure that all circuits are voltage-free.
) Note:
Before disconnecting any cables, label any unlabeled cables to
ensure correct reconnection, and check the switch positions of the
removed part to set the switches of the new part accordingly.
To replace a FRU, use the appropriate tools. The tools are provided along with the
equipment. Replacement tools may be ordered from the supplier. All screws have a
right-hand thread, turn the tool clockwise for tightening and counter-clockwise for
loosening.

Depending on the configuration of the Node C the FRU can be
equipped with a 50-Ohm termination resistor. In such a case, use
the termination resistor of the old FRU to terminate the respective
connector of the replacement part.
After the replacement of a component, check whether the system
has to be levelled anew.
Do not forget to reinstall the front cover after the replacement
procedure to ensure safe operation.
If any FRU not contained in the following chapter needs to be replaced, contact
customer service for additional instructions.
