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.
Repeaters are used to extend the transmission range if weak signal transmissions occur
within the coverage area due to indoor applications, topological conditions or distance
from the transmitter. In the downlink path, the repeater picks up the signal from a donor
antenna of an existing cell, amplifies and re-transmits it into the required dark spot. In the
uplink direction, the repeater receives signals from mobile stations present in its coverage
area and re-transmits the signals to the corresponding base station.
In the downlink (DL), the Node AM4 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 AM4 constantly monitors the quality of the signals passing through it.
2.2. The Node AM4 Repeater
Note: The denomination "Node AM4" says that this RF repeater is equipped with
slots for 4 RF cards / dummy cards.

3. Installation
3.1. Mechanical Installation
3.1.1. Health and Safety for Mechanical Installation
Read and observe chapter 1.2.
1. Caution: Risk of injury by the considerable weight of the unit falling. Ensure there is
adequate manpower to handle the weight of the system.
2. Caution: Risk of serious personal injury by equipment falling due to improper
installation. The installer must verify that the supporting surface will safely support the
combined load of the electronic equipment and all attached hardware and
components. Only use sufficiently dimensioned screws for mounting and make sure
the mounting material is adequate for the mounting surface.
3.1.2. Property Damage Warnings for Mechanical Installation
1. Attention: 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 supplier are not
met.
2. Notice: Due to power dissipation, the unit may reach a very high temperature.
Ensure sufficient airflow for ventilation. When mounting the Node AM4 into a train, a
temperature test in maximum configuration (i.e. 4 RF cards) must essentially be
made. A minimum air flow of 50 m³/h is required where the maximum air flow of the
Node AM4 is 220 m³/h which will be reached at an environmental temperature of
around 45°C and above. We suggest to supply the repeater at the air inlet with fresh
air and to conduct warm air at the air outlet off the Node AM4 without feedback in
order to avoid a 'thermal short-circuit'.
3. Notice: It is recommended only to use the mounting hardware delivered by the
manufacturer. 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. The specifications for stationary use of the unit must not
be exceeded.
Note: Exceeding the specified load limits may cause the loss of warranty.
4. Notice: Only use sufficiently dimensioned screws for mounting and make sure the
mounting material is adequate for the mounting surface.
5. Notice: Observe that for M12 connectors the nominal torque is 1.0 N-m.
6. Notice: When connecting and mounting the cables (RF, mains, ...) ensure no water can penetrate into the unit through these cables.
7. Notice: Do not operate the repeater without terminating the antenna connectors. The
antenna connectors may be terminated by connecting them to their respective
antennas or to a dummy load.
Unless otherwise agreed to in writing by CommScope, CommScope’s general limited
product warranty (http://www.commscope.com/Resources/Warranties/) shall be the
warranty governing the Node AMs, including the installation, maintenance, usage and
operation of the Node AMs.

Note 2: Depending on the respective frequency range, the maximum equipment of 4
RF cards is not necessarily required but all unused slots need to be
assembled with a dummy card for sufficient airflow and provided IP class.
Note 3: It is mandatory that one RF card is installed into slot 1 as a (passive) dummy
card does not fit into slot 1. A dummy card has to be installed into slots with
no RF card to guarantee correct airflow and watertightness for the active
components. For layout please refer to figure 4 2 Exemplary layout of a Nod e
AM4, maximum equipment in chapter 4.3 Components.
Note 4: It is recommended to disconnect the Node AM4 from mains (power-supply
line) before an RF card is mounted or dismounted. In case the Node AM4 is
not allowed to be disconnected from mains, the RF card which needs to be
replaced must be disabled via software in the Technician page before
removing it. This is to avoid possible damage when inserting the new RF card
Note 5: Please observe that the RF cards must always be packed separately for
transport.

figure 3-2 Example for interconnecting cabling for a Node AM4 (combiner with three
pairs of band ports)
3.2.5. Connection of the Antenna Cables
The antenna connectors of the Node AM combiner are N female. However, the antennas
may also be mounted directly on the RF card connectors which are QN. All connectors
are located at the front 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.
In applications such as trains and ferries, it is highly recommended to use
directional antennas with good front-back-ratios (40 dB is typical) because they
improve isolation and cell-site selectivity.
Smaller diameter cables are less expensive and easier to install but have worse
performance.

3. Installation
3.2.9. Connection to the Node AM
The Node AM is set up, configured and monitored using a PC. The connection to the
Node AM can be established locally via an Ethernet cable or remotely via modem. The
local connection is easy to set up and much faster in operation. The local connection
should be used for initial setup and whenever the operator is at site.
3.2.9.1. Setting up the Local Connection
A standard Ethernet CAT5 cable is supplied with the Main
Unit of the Node AM. Connect the cable to the Node AM
and the network port on the PC. The Node AM hardware
supports 10 or 100 megabit / sec Ethernet connections.
After the connection is made properly, the red and green
LEDs near the Node AM network connector will flash.
Likewise, the network connector on many PCs has LEDs
that indicate when a hardware connection is established.
The network hardware will determine the highest speed
supported by both devices.
figure 3-6 Connecting the
CAT5 cable to the Node AM for
the local connection
The operating system of most PCs will automatically establish the hardware and software
network connection. No setup or system changes are required on the PC to establish a
local connection with the Node AM.
Normally, the connection can be made either before or after the Node AM and PC are
powered up. If there are problems, make sure the cable is fully inserted at both ends.
Make sure the PC network driver is not fixed at 1 GB/second. With the cable connected
restart the PC. If that fails, restart the Node AM.
3.2.9.2. Setting up the Remote Connection
Setting up the remote connection is slightly more involved than setting up the local
connection. A separate manual is provided to explain how to setup the remote connection.
Via the remote connection, the operator can monitor and control the Node AM using the
Web browser interface remotely.
In addition, the remote connection may be used for an OMC-type software platform and
SMS alarm forwarding.

4. Functional Description
4. Functional Description
4.1. Architecture
The Node AM4 is designed to amplify signals between multiple mobiles and a base
station. The unit consists of a filter and amplifier chain in the downlink and one filter and
amplifier chain in the uplink. The uplink and downlink paths are connected via a duplexer
on both ends of each path. After that the signals are combined by the crossband coupler
with the other frequency bands.
In the uplink path, a signal originating from the mobile is divided by the crossband coupler
into the different frequency bands and is separated from the downlink signal via the UL
IN duplexer. It is then amplified by a low noise amplifier (LNA), which is like the duplexer
part of the RF card. The RF card down-converts the signals to the IF and converts the
analogue signal into a digital signal. Digital filtering / signal processing is done at the main
board of the subrack with single band RF cards, and with dual-band RF cards in the cards
themselves. Then, the digital signal is converted into an analogue signal, is up-converted
and amplified. Finally, the signal is sent to the PA and combined with the downlink signal.
After that the signals from all RF cards are combined at the crossband coupler and
forwarded to the Base Station port of the Node AM4 system.
In the downlink path, a signal originating from the base station is divided by the crossband
coupler into the different frequency bands and is separated from the uplink signal in the
donor duplexer. It is then amplified by a low noise amplifier (LNA), which is like the
duplexer part of the RF card. The RF card down-converts the signals to the IF and
converts the analogue signal into a digital signal. Digital filtering / signal processing is
done at the main board of the subrack with single band RF cards, and with dual-band RF
cards in the cards themselves. Then the digital signal is converted into an analogue
signal, is up-converted and amplified. Finally, the signal is sent to the PA and combined
with the uplink signal. After that the signals from all RF cards are combined at the
crossband coupler and forwarded to the mobile port of the Node AM4 system.
Apart from the difference in digital signal processing as explained in the sections above,
the functionality of dual band and single band RF cards is principally identical in both the
UL and DL paths.
For an overview of the individual components, please refer to chapter 4.3 Components.
4.2. Features
4.2.1. Digital Channel Filters
The Node AM has a multitude of digital filters. The maximum bandwidth of each filter is 5
MHz. If a greater bandwidth than 5 MHz is required, two or more sub-band filters are
linked together without increased amplitude or delay ripple. The number of sub-band
filters is automatically allocated and shown by the repeater software (Technician Setup
page).
The user has to select the downlink start and stop frequencies (wide-band filter load) or
centre frequency and filter bandwidth (narrow-band-filter loads) of each sub-band filter.
For further information regarding sub-band filter settings refer to the User’s Manual for
the Node AM software.
Page 34 MF0121ACP_uc.docx Manual for Node AM4
4. Functional Description
4.2.2. Frequency Hopping
The Node AM repeater supports base band hopping (BBH) and synthesized frequency
hopping (SFH) in GSM networks.
For base band hopping (BBH) even channelized digital filters may be used. For
synthesized frequency hopping (SFH) band selective filters are needed.
4.2.3. Filter Types
Please observe that the selectivity of the filter types is not yet available with the current
software version. At the moment only the filter type “Normal” will be active even if another
filter is selected. From which software release onwards the selectivity described in the
following will be implemented in future is not defined, yet.
In future, there will be different filter types available for each sub-band. These filter types
are:
Normal (good selectivity and group delay)
Wide (low selectivity and low group delay)
Narrow (high selectivity and high group delay)
Auto (preferred mode)
It is advisable to select the “Auto” filter. In this case the repeater selects the best filter
type (normal, wide or narrow) automatically. The choice of filter type depends on the input
signal strength and position of the adjacent channel signals.
If narrow, strong adjacent cannel signals are received, the “Narrow” filter is selected. If
the adjacent channels are far from the desired band/channel, the “Wide” filter type is used.
For all other configurations, the “Normal” filter is selected.
4.2.4. Status Information
The Status and Reports menu, which is accessible via the home page of the web
interface, provides information about the current gain, output level and receive signal
strength indication (RSSI) values.
The RSSI provides controlling and monitoring of the receive level of a Base Station (DL
RSSI) or user equipment (UL RSSI) to a Node AM. 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. A corresponding measurement is also made
for the output levels.
RSSI measurements are done for each band segment; for further details please refer to
the Node AM/ Node AM SW manual.
MF0121ACP_uc.docx Manual for Node AM4 Page 35
4. Functional Description
4.2.5. Alarm Forwarding
Alarms can be forwarded from the Node AM to a defined phone number or to the OMC
via the Ethernet port on the UI2 Board (see chapter 4.3.6) or via an optional modem. This
enables the provider to control and to query the status of the network via packet switched,
circuit switched, or LAN connection. Faults and irregularities can be recognized and
eliminated.
With a modem equipped the Node AM also provides an SMS feature, by which the unit
is able to send out alarm messages as SMS. For further details please contact
CommScope.
4.3. Components
The actual configuration of the individual Node AM4 can be seen in the configuration list,
which is part of the delivery. It is also available as an electronic list accessible via
software.
The following figure shows the layout of a system using single-band RF cards only. If one

4.3.2. Digital Channel Modules (DCM) / RF Cards
The digital channel module (DCM) is the RF digital-converter in both directions for
Downlink and Uplink. The Downlink and Uplink will be separated in the duplexer and the
desired signal will be amplified by an LNA which is – like the duplexer – an integrated part
of the RF card. The RF card down-converts the signals to the IF and converts the
analogue signal into a digital signal. Digital filtering / signal processing is done at the main
board of the subrack with single band RF cards, and with dual-band RF cards in the cards
themselves. Then, the digital signal is converted into an analogue signal, is up-converted
and amplified. Finally, the signal is sent to the PA (internal PA or mounted on the RF card)
and combined with the other link in the second duplexer.
The following figure shows the single band DCM, RF cards:
figure 4-4 Single-band DCM, RF card, low / medium power (left) and high power wit h
additional DL amplifier (right)
Optionally, medium power dual band RF cards
are available, by which two bands, for instance
the 800/900 bands or the 1800/2100 bands,
can be combined in one module. Thus, the
maximum number of bands per Node AM can
be increased to up to 8*.
Apart from the difference in digital signal
processing as explained above, the
functionality of dual-band and single-band RF
cards is principally identical.

4.3.6.3. O pti onal Modem s
4. Functional Description
Note: As optional modem, different types can be used for the Node AM: PHS8
(successor of HC25), PLS8 (for LTE), TRM-5, and MC88 modems. The layout
of all types is alike. In the following, the general term "modem" is shortly used,
referring to any of these types. GPS is only supported by PHS8 (formerly HC25)
and PLS8. Modem type RV50X is supported but it is not available from
CommScope. It can only be ordered directly from the manufacturer.
A wireless modem is used to establish a remote connection to the Node AM. The
connection may be circuit switched or packet switched and is used to change the
parameters of the unit, check and clear alarms, or collect measurement and quality
statistics. Furthermore, the modem is requested at the Node AM to alert the operator
when there is an alarm.
The modem settings (i.e. which type of modem, Initstring, etc.) may only be changed
locally. Should a different modem be used, the operator should ensure that the settings
are changed prior to leaving the site.
For technical data of the individual modems, see chapter 7.5.1HC25 / PHS8 / PLS8 / MC88 / TRM-5. For the technical data of type RV50X, refer to the data sheet of the
manufacturer.
Initstrings
The initialization string (abbreviated by initstring) depends on the operator’s network and
the modem. It may be necessary to adjust the initstring in the field.
When a modem is selected in the Node AM web interface the default initstring for this
modem is suggested. The initstrings for the different modems are listed in the software
description for the Node AM.
The modem allows remote control and
maintenance of the Node AM.
Parameters may be changed; alarm and
measurement statistics may be
acknowledged and collected by the
OMC.
The modem is installed in the side tube
of the unit. To avoid a collision between
modem connectors and combiner
(especially with 4-way combiners), an
adapter kit for modem installation is
used (see chapters 5.2.2 and 8).

5. Maintenance
5. Maintenance
5.1. General
Read and observe chapter 1.2.
Caution: The unit reaches high temperature in operation. Risk of burns by hot
surface. Do not touch the unit before it has sufficiently cooled down.
Notes:
The Node AM does not require any preventative maintenance measures apart from
the Battery Backup Unit (BBU). It is recommended to replace it after 4 years of
operation (see chapter 4.3.6).
We recommend checking the cleanliness of the unit and in particular of the fan unit at
appropriate intervals depending on the degree of dust and dirt at the installation site. If
necessary, any dusty or dirty areas / parts should be cleaned at regular intervals, which
also depend on the degree of dust and dirt at the installation site.
For cleaning, the following procedure is recommended: use an industrial vacuum
cleaner and, first, vacuum the outside of the unit. For inside cleaning, remove all plugin units (as well as the fan unit) according to the instructions in the following chapter,
and then, vacuum the fan unit, the cooling fins of the plug-in units as well as the
complete interior of the NodeAM.
In the event of a malfunction, the user should check the status of the antennas, feeder
cables, connectors, and mains power before replacing any components.
When sending back the unit, use an appropriate packaging; see chapter 7.3. We
strongly recommend using the original packaging. The transport protection cover (see
chapter 3.1.3) should also be installed for units with bottom type fan unit (see chapter
5.2.7.2). For a better shock protection of the DC connectors and main board the RF
cards must be packed separately.
5.2. Replacement of Components
Read and observe chapter 1.2.
Maintenance of the Node AM should be performed on a field replaceable unit (FRU) basis
only. Do not damage the warranty labels on the components as this voids the warranty.
Unless otherwise agreed to in writing by CommScope, CommScope’s general limited
product warranty (http://www.commscope.com/Resources/Warranties/) shall be the
warranty governing the Node AMs, including the installation, maintenance, usage and
operation of the Node AMs.
The spare parts list contains only units that can be replaced without tuning or soldering
work. It is not recommended to replace any components inside the Node AM itself,
except, RF cards, combiner, and modem. Regarding the replacement of a PSU observe
the corresponding Note in chapter 5.2.5.
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.
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 an FRU, use the appropriate tools. The tools are provided along with the
equipment. Replacement tools may be ordered from the supplier.
SMA connectors have a specified torque of 60 N-cm. All screws have a right-hand thread,
turn the tool clockwise for tightening and counter-clockwise for loosening. Use an
appropriate tool to fasten and unfasten connectors and screws. Do NOT overtighten the
connectors or screws!

Note: Terminate each open RF connector by 50 ohms, to avoid internal oscillation.
Note: Observe that all components have watertight sealings.
After replacement of components all screws have to be fastened tight to
ensure watertightness.
Note: After the replacement of a component, check whether the system has to be
levelled anew.
Note: Do not forget to reinstall the splash water shield and vandalism cover (if this
option is installed) after the replacement procedure to ensure safe operation.
Note: It is recommended to disconnect the Node AM from mains (power-supply
line) before an RF card is mounted or dismounted. In case the Node AM is
not allowed to be disconnected from mains, the RF card which needs to be
replaced must be disabled via software in the Technician page before
removing it. This is to avoid possible damage when inserting the new RF
card.
If any FRU not contained in the following chapter needs to be replaced, please contact
customer service for additional instructions.

5.2.1. Multiband Combiner
Danger: Electrical hazard. Danger of death or fatal injury from electrical current
inside the unit in operation. Before opening the unit, disconnect mains power.
Danger: Electrical hazard. Danger of death or fatal injury from electrical current
due to a possible short-circuit caused by incorrect handling. Make sure the
system has been correctly grounded (earthed) as described in chapter 3.2.3 and
connected via external circuit breaker (see chapter 3.2.8).
Caution: Rotating fans. Risk of injury in operation. Wear tight-fitting clothes and
disconnect mains before working inside the unit.
Note: Removal and installation of a combiner on-site must only be done by a service
technician of CommScope or by a qualified person authorized and trained for
this procedure who is observing the corresponding safety procedures required
by local, regional and country-specific regulations which have to be observed
during all times of this procedure.
Notes:
The figures in this chapter show the
combiner type with three pairs of band
ports. The procedure is exactly the same for
combiners with two band port pairs.
Unscrew the combiner and pull it out
carefully with your hands.
As the long hole of the combiner’s carrier plate is hooked into a screw of the modem
mounting plate, this is pulled out to a certain degree, as well:
Mounting plates of combiner and modem connected by
screw locked into long hole (seen from both sides).
MF0121ACP_uc.docx Manual for Node AM4 Page 55
A
Unhook the plates and disconnect all cables from the combiner. Remember their
positions for later reconnection. (For replacement of components on the carrier plate, now
refer to the corresponding chapter.)
t four band combiners, the combiner is tied to the
carrier plate by a mounting plate that is fixed with
screws. To avoid a collision between modem
connectors and combiner (particularly with 4-way
combiners), an adapter kit for modem installation
is used (see figure 5 1 and chapter 8).
Exchange the combiner and re-connect all cables
at the correct positions.
5. Maintenance
Note: In case of upgrading with a different type
of multiband combiner, make sure that the
operating frequency band of the modem still fits to
the combiner frequency bands.
Caution: Before sliding the new module in, make sure that no cables inside, e. g. from
the PSU, obstruct the way and may get squeezed or damaged in the process. Make
also sure that no cables get disconnected by accident. In case of obstructing cables
that may get damaged, send the unit back to the supplier for repair.
Carefully slide in the modem carrier plate, using
the guide rails provided at the top and bottom of
the slot for positioning the module correctly.
Then, reconnect the modem and combiner plates
by hooking the screw of the modem plate into the
long hole of the combiner plate.
Guide rails
Position the combiner plate in the same guide rails
as the modem plate and slide in the combiner
carefully, also pushing the modem carrier plate
back in.
Attention: Be careful with all cables connected. Do not squeeze or damage any cables,
and make sure that no cables get disconnected by accident.
Fasten the screws of the combiner tight to restore watertightness (for screw positions,
see illustration at the beginning of the procedure).

5.2.2. Modem / Battery
1. Caution: Electrolyte inside. Risk of health hazards associated with electrolyte
leakage. Do not disassemble, puncture, modify, drop, throw, or cause other
unnecessary shocks to batteries.
2. Caution: High current if shorted. Risk of injury by high current. Do not short circuit the
batteries.
3. Caution: The batteries might be hot. Risk of burns by hot surface. Do not touch the
batteries before they have sufficiently cooled down.
Do not put the batteries to the garbage but dispose of them properly according local
and/or regional regulations.
Notice:
Currently, the battery condition is only detected at shutdown, by making sure the battery
has enough charge to allow a complete shutdown process. If the battery is dead,
missing, or not able to hold a charge lasting more than a minute or two (the time for a
normal shutdown, which could be up to 10 minutes), this will be noticed by the software
at the next power up and an alarm raised. However, this means a “good” battery
condition can also only be detected at shutdown. If a bad battery is replaced with a good
battery in the field, the alarm will not be cleared immediately at the next bootup. Instead
the system will have to have a normal power shutdown and then the alarm will be cleared
at the following bootup. So, the procedure for replacing a failed battery should be:
1. Shutdown the system.
2. Replace the battery.
3. Power up (alarm will still be raised).
4. Shutdown the system.
5. Power up (alarm will now be cleared).
If this is not done, the alarm will be only cleared after the next shutdown and power up
event of the system. Also, observe that an alarm is raised once the battery disconnect
button on the UI1 board is pressed and the unit is powered up again. To delete the false
alarm, the unit has to be shut down and powered up again. During the shutdown, the
battery disconnect button must not be pressed.
Notice: For the replacement procedure, also observe the warnings in chapters 5.1 and
5.2.1.
Notice: For tightening
SMA connectors, always
use an appropriate torque
wrench:
Modem and battery are located on a carrier plate located behind the combiner carrier
plate. Thus, for replacing the modem or the battery, the combiner has to be removed
first. To do so refer to chapter 5.2.1, observing the corresponding warning messages.

limitations for the number of dual-band cards that may be equipped as specified in
chapter 7.1.
Replacing a single-band with a dual-band card impacts the share of available filters.
A total of 48 (backplane-controlled) filters can be defined at freely variable proportions
for all single-band cards equipped. For dual-band cards, these filters are not available
but each dual-band card provides additional 32 wide-band filters, which can be
variably shared among the two bands of this card only. Thus, if a single-band card for
which more than 32 filters were defined is replaced, these can no longer be provided
by the dual-band card.
This chapter shows the single-band cards but it is valid for dual-band cards as well.
To replace an RF card or to upgrade the Node AM with additional RF cards, proceed as
follows:
To remove an RF card / or dummy card (in case of an
upgrade):
Disconnect the cables.
Loosen the four socket head cap screws M3x16 mm)
and take the RF / dummy card out.
To install the RF card:
Use the guide rails on top and bottom to fit in the RF
card smoothly.
Note: Fasten the screws of the RF card tight to
restore watertightness. To do so, first, just slightly
tighten the screws crosswise in order to avoid cant, and
when all four screws are positioned correctly, fasten
them tight.
Use the guide rails on top and bottom to fit in the RF
card smoothly.
Reconnect the cables.

5. Maintenance
Note: If an RF Card is exchanged by a card of another type, e.g. an AF2125 by an
AF1825/2125, resetting this card via the Technician Setup menu of the SW
(see SV manual) is recommended.
In case of an upgrade, also observe the following:
If the multiband combiner has to be upgraded as well (i.e. two-band combiner to three-
band combiner), refer to the instructions in chapter 5.2.1 for the exchange.
The required RF cables are part of the delivery of the RF card.
Connect the individual BTS band ports of the combiner to the BTS ports of the according
band of the RF cards.
Connect the individual Mobile band ports of the combiner to the Mobile ports of the
according band of the RF cards.

Detailed System Description – Single-Band Cards
Node AM RF cards convert the RF into digital signals and transfer them to the Node AM
rack for digital filtering. The digital architecture allows sub-band filtering and is shared
between all RF Cards inserted into the Node AM rack. The Node AM4 can provide up to
48 filter resources (up to 5 MHz each). Additional filtering capability is provided by on-
card digital signal processing at dual-band RF cards to satisfy increasing demand of subbands for further RF-bands or MIMO deployments. When the sub-band bandwidths are
greater than 5 MHz, the filter resources are grouped together, without phase or amplitude
ripple, where the sub-band is defined by a start and stop frequency. The total number of
used filter resources is determined by adding the number of filter resources required for
each sub-band.
For example, if there are three sub-bands with 4 MHz for the first sub-band, 11 MHz for
the second sub-band, and 20 MHz for the third sub-band, then 1 filter resource is required
for the first sub-band, 3 filter resources are required for the second sub-band and 4 filter
resources are required for the third sub-band. The total number of used filter resources
in this example is 8. However, the maximum available bandwidth (240 MHz) will only be
achieved with sub-band bandwidths of integer multiple of 5 MHz.
The following diagram shows examples for filter resources allocation:

Detailed System Description – Dual-Band Cards
With the increasing demand for mobile communication, additional radio frequency (RF)
bands are globally assigned to meet that demand. In addition, better utilization of the
radio spectrum is being addressed by Multiple-In Multiple-Out (MIMO) antenna
technology and techniques. However, basically all measures to increase the
communication link capacity result in an increased number of parallel operated radio front
ends. In response to this trend, CommScope has enhanced the radio band capacity of its
existing Node AM platform by providing Dual Band RF cards. Following a software
upgrade, two medium power RF front ends can be operated in the same space of a legacy
single band plug-in module.
Thanks to the on-card digital signal processing functionality, up to 32 filter resources (0.2
… 5 MHz each) are available per dual card. Depending on the upgrade goal, i.e.
increasing the number of RF bands or MIMO performance, dual band RF cards for interband, e.g. 8/9 or 18/21, combination are available.
When using CommScope’s Node AM chassis in situations where the sub-band
bandwidths are greater than 5 MHz and where the sub-bands are defined by a start and
stop frequency, the filter resources are grouped together, without phase or amplitude
ripple. The total number of used filter resources per dual band card is determined by
adding the number of filter resources required for each sub-band in both RF bands
together. For example, if there are three sub-bands with 200 kHz for the first sub-band
and 10 MHz for the second sub-band in the 1800 MHz band and 20 MHz for the third subband in the 2100 MHz band then one filter resource is needed in the first, two in the
second, and four in the third sub-band. The total number of filter resources used is seven.
