Powerwave Technologies Inc. reserves the right to make changes to the documentation and equipment, including but not limited to component substitution and circuitry changes. Changes that impact this document may
subsequently be incorporated in a later revision of this document.
This Powerwave product is designed to operate within the Normal Operating (typical operating) ranges or conditions specified in this document. Operation of this equipment beyond the specified ranges in this document
may cause (1) spurious emissions that violate regulatory requirements; (2) the equipment to be automatically
removed from service when maximum thresholds are exceeded; or (3) the equipment to not perform in accordance with its specifications. It is the Operator's responsibility to ensure this equipment is properly installed and
operated within Powerwave operating specifications to obtain proper performance from the equipment and to
comply with regulatory requirements.
The rated output power of this equipment is for single carrier operation. For situations when multiple carrier signals are present, the rating would have to be reduced by 3.5 dB, especially where the output signal is re-radiated and can cause interference to adjacent band users. This power reduction is to be by means of input power
or gain reduction and not by an attenuator at the output of the device. Input power is rated at 115/230VAC, 50/
60Hz, and should be protected with a 20 A breaker. Power strips should, at a minimum, conform to this requirement to prevent equipment damage and possible overload.
Federal Communications Commission (FCC)
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to
part 15 of the FCC Rules. Changes or modifications not expressly approved by Powerwave Technologies, Inc.
for compliance could void the user’s authority to operate this equipment. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio communications. Operation of
this equipment in a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.
Industry Canadian Requirement
All Powerwave apparatus introduced on the Canadian market meet all requirements of the Canadian Interference-Causing Equipment Regulations. The -20dB bandwidth is 80MHz.

Product Description
Introduction
This manual contains information and procedures for installation, operation, and maintenance
of the Wideband Radio Head (WRH). The manual is organized into chapters as follows.
Chapter 1 - Product Description
Chapter 2 - Controls and Indicators
Chapter 3 - Installation
Chapter 4 - Maintenance
Chapter 5 - Specifications
Scope of Manual
This manual is intended for use by service technicians familiar with similar types of equipment.
It contains service information required for the equipment described and is current as of the
printing date. Changes which occur after the printing date may be incorporated by a complete
manual revision or alternatively as additions.
Safety
It is necessary that any personnel involved in installation, operation or service of units included
in a Powerwave Distributed Antenna System (DAS) understand and follow the below points.
044-05251 Rev A
•
Powerwave WRHs are designed to receive and amplify signals from one or more base
stations and retransmit the signals to one or more mobile stations. And, also to act the
other way round, that is to receive signals from one or more mobile stations, amplify
and retransmit the signals to the base stations. Powerwave WRH systems must be
used exclusively for this purpose and nothing else.
•
Units supplied from the mains must be connected to grounded outlets and in conformity
with the local prescriptions.
•
Power supply units supplied from the mains contain dangerous voltage that can cause
electric shock. Disconnect the mains prior to any work in such a unit. Local regulations
are to be followed when servicing such units. Authorized service personnel only are
allowed to service units while the mains is connected.
•
The WRH cover must be secured in opened position, for instance by tying it up.
Otherwise, the cover can be closed by the wind and cause your fingers getting pinched
or your head being hit.
•
When working on a WRH on high ground, for instance on a mast or pole, be careful not
to drop parts or the entire WRH. Falling parts can cause serious personal injury.
•
All RF transmitting units, including WRHs, will generate radio signals and thereby give
rise to electromagnetic fields that may be hazardous to the health of any person who is
extensively exposed close to an antenna.
•
Beryllium oxide (BeO) may be contained in power devices, for instance in dummy loads
in directional couplers (DCC), in combiner units (CMB), and in attenuators on the FON
board. Beryllium oxide is poisonous if present as dust or smoke that can be inhaled. Do
not file, grind, machine, or treat these parts with acid.
•
Coaxial cables used in many Powerwave systems have the insulation made of PTFE,
polytetrafluoro ethylene, that gives off small amounts of hydrogen fluoride when
heated. Hydrogen fluoride is poisonous. Do not use heating tools when stripping off
1-1
Wideband Radio Head
Safety
coaxial cable insulation. No particular measures are to be taken in case of fire because
the emitted concentration of hydrogen fluoride is very low.
•
A lithium battery is permanently mounted on CU units, and in FON and OCM units. Due
to the risk of explosion, this battery must only be removed from the board by an
Powerwave authorized service technician.
•
NiCd batteries are mounted on the FON unit. These batteries contain environmental
poisonous substances. If replaced, the old batteries should be taken care of as stated
in the local prescriptions.
•
The FON unit contains a class IIIb laser transmitter that emits 2 – 4mW invisible laser
radiation during operation. Avoid direct exposure from unconnected laser transmitter or
fiber cord as follows:
– Do not power up the FON unit if a fiber cable is not attached to the fiber output UL
port, neither if a fiber cable is attached to the port but unattached in the other end.
– Never look in the end of a fiber cable. The 1310nm and 1550nm laser light is not
visible, so no signal identification can be made anyway. Use always an instrument,
such as a power meter to detect signaling.
– Never use any kind of magnifying devices that can focus the laser light to an
unaided eye.
Warning Signs
The following warning signs must be observed and be kept clean and readable.

Human Exposure of RF Radiation
Safe distances must be kept when working around antennas. The following paragraphs
describe the cautions to be aware of during the installation and maintenance of antenna
systems and how to calculate safety distances needed for RF radiation at different antenna
power and frequencies.
Antennas
To be able to receive and transmit signals, a WRH is connected to a donor antenna directed
towards the base station and a service antenna directed towards the coverage area. A fiber
optic cable from the base station might, however, be substituted for the donor antenna.
Installation and Maintenance of Antenna Systems
Installation and maintenance of all antenna systems must be performed with respect to the
radiation exposure limits for public areas. The antenna radiation level is affected by WRH
output power, antenna gain, and transmission devices such as cables, connectors, splitters
and feeders. Also have in mind the system minimum coupling loss, typically between 25dB and
35dB, is determined by a standard with the purpose to protect base stations from noise and
other performance dropping effects.
Radiation Exposure
The World Health Organization (WHO) and International Commission on Non-Ionising
Radiation Protection (ICNIRP) have determined recommendations for radiation exposure.
ICNIRP recommends not to exceed the following radiation power for public exposure:

For antennas larger than 20cm the maximum radiation power can be calculated by using the
following formula:
S = --------------------2
4×π×r
whereS = Radiation power in W/m²
P = Output power in W
r = Distance between antenna and human in meter
To tackle the worst case successfully, the calculation does not consider system power
reducing actions, such as power control and DTX. Figure 1-1 shows the safety distance to an
antenna due to the RF radiation. The distance depends on antenna output power and
frequency, which is illustrated with the two graphs. One graph applies to 4.5W/m2 (900MHz)
and the other to 9.0W/m2 (1800MHz) or 10.0W/m2 (2100MHz). The safety distance range is 0
to 1.4 meters which covers an antenna power range of 10dBm to 50dBm (0.01W to 100W).

Electrostatic Discharge (ESD)
ESD can severly damage essential parts of teh equipment if not handled carefully. Parts on
printed circuit board assemblies (PCBA) as well as other parts in the equipment are sensitive
to ESD. Never touch the PCBA or uninsulated conductor surfaces unless absolutely
necessary.
If you must handle the PCBAs or uninsulated conductor surfaces, use ESD protective
equipment or first touch the chassis with your hand. Never let your clothes touch PCBAs or
uninsulated conductor surfaces and always store PCBAs in ESD-safe bags.

Overview
Figure 1-2 Powerwave Wideband Radio Head (WRH)
Powerwave WRHs work as bi-directional on-frequency amplifiers used to fill out uncovered
areas in wireless mobile systems such as base station fringe areas, tunnels, convention
centers, airports and business buildings. It receives, amplifies and transmits signals to/from a
base transceiver station (BTS) to/from mobile stations (MS) with both directions being served
simultaneously. Connections to the WRH are made with N-type or 7/16" male connectors.
WRHs are microprocessor controlled with alarm and operational status LEDs visible on the
front cover. Cooling is provided through convection heat dissapation.
Operational parameters, such as gain, channel number and power levels are set using a PC
running Powerwave OM-Online software which can communicate with the WRHs either locally
or remotely via modem. Remote operation can be performed via PSTN or a GSM net. The
Operation and Maintenance System (OMS) provides for Network Operations Center (NOC)
configuration and alarm monitoring.
WRHs can be configured in many combinations depending on the wireless system, single or
double system operation, and output power. The following paragraphs provide a description of
the different models of WRH’s available.
WRH
The Standard WRH is used for analog or digital systems such as GSM, TACS, ETACS, AMPS,
DAMPS, CDMA and WCDMA. It can be equipped with two bands in the cabinet and two bands
in a high cover. It has a fiber optic donor port and an RF port for a service antenna (or RF cable)
and is designed to be connected to a BTS via a BMU or OCM.
A booster option is available for the standard WRH to provide greater output power. This unit
is equipped with a 6dB Booster Amplifier (BA) in the downlink path. The BA reduces the
number of bands with one band per BA used in the cabinet and an additional one band if a high
cover is used. The BA is located in the cabinet and is supplied from the existing PSU. For two
bands, a high cover is used.
044-05251 Rev A

Wideband Radio Head
Overview
WRH-V
The WRH-V is designed to provide a higher output power level and comes equipped with a
MCPA in the downlink path. The MCPA reduces the number of bands to one band per MCPA
used in the cabinet and an additional one band if a high cover is used. The MCPA is located
in the cabinet and is supplied from the existing PSU. For two bands, a high cover is used.
Chassis Design
The WRH is housed in a cast aluminium waterproof chassis, class NEMA4 / IP65 approved for
outdoor use but is also suited for indoor installations. The chassis consists of a cabinet and a
cover attached with hinges. The cabinet contains the WRH circuitry. The cover comes as either
a low or high version. The high cover can be used as an empty cover or be equipped as a part
of the WRH or an independent WRH unit. A WRH with a high cover that is equipped as two
independent units can, for example, be equipped for channel selective operation in the cabinet
and band selective operation in the cover.
Indside the WRH, a number of amplifier PCBAs are individually shielded and located under a
metal cover that can be opened outward. These PCBAs are of different types depending on the
supported system. Functionally, all WRHs are built up with a number of sub units. These are
listed and described in the following sections.
Sub Unit Overview
A number of amplifier PCBAs are individually shielded and located under a metal cover inside
the WRH. This cover can be opened outward for acess. These amplifier PCBAs are of different
types depending on the supported system. All of the WRHs are built up with a number of sub
units which are described in the following sections.
Wideband Amplifier PCBA (WBA)
WRHs can handle multiple carriers over a wide band. Each band requires one WBA for the
uplink and dowlink, and one PA for the downlink. The cabinet can be equipped with up to two
WBAs and two PAs supporting two bands. Positions 1 and 3 are assigned for a WBA.
Power Amplifier PCBA (PA)
The PA is used to amplify the output signal from the WBA in the dowlonk direction and reside
in positions 2 and 4.
Multi-Carrier Power Amplifier PCBA (MCPA)
Installed in the WRH-V only, the MCPA is used to amplify the output signal from the WBA. Each
MCPA can handle one band in the downlink direction. It requires an extra heat sink element on
the outside of the cabinet or high cover to dissipate the heat generated. The MCPA occupies
positions 3 and 4 in the cabinet and 7 and 8 in a high cover.
Booster Amplifier PCBA (BA)
A WRH can be modified with a BA on the DL path to increase the output power by 6dB
(typically) depending on system configuration. This BA can operate with a maximum of 2
channels and occupies position 3 in the cabinet and position 7 in a high cover. It also requires
an extra heat sink element on the outside of the cabinet or high cover. Some configurations use
the existing PSU while others require a second PSU.
Distribution PCBA (DIA)
The DIA is the core distribution PCBA on which all other PCBAs and units connect to in the
cabinet with the exception of the PA. A shielded metal frame on the DIA provides the mounting
location for the CU, ALI and RCIs, if used.

Fiber Optic Distribution Networks
Fiber optic networks are setup identically to data networks. WRHs are connected is a star
configuration as illustrated in Figure 1-6. In this example, a Base Station Master Unit (BMU) is
fed by a BTS via an RF cable. An Optical Converter Module (OCM) could also be used
depending on the system configuration. The BMU or OCM contain three FONs and provide
continuity to the FONs in the four WRHs. By using Wave Division Multiplexers (WDMs) and
Optical Splitters (OSPs) in the WRHs, the distribution net can be built up with a combination of
star and daisy-chain connections using double or single fiber.

Multi-Operator Configurations
Multi-operator systems require the use of Point of Interconnects (POIs), RF Combining
Modules (RCMs) and OCMs as illustrated in Figure 1-7. In this simple example, two operators
have two sectors each. Each sector is connected to a POI and then to a RCM. The RCM is
interconnected with an OCM via coaxial cables. The combined DL and UL signals are
converted to optical signals in the OCM and then distributed to the ARs. Additional information
is provided in the Fiber Optic Equipment Operation and Maintenance Manual.

Software and Hardware Compatibility
Alarm Port (15-pin D-sub female) - Used for external alarm sensors and alarm
equipment. It is located on the DIA to the left in the cabinet. The port has four
alarm inputs, EAL1 – EAL4, and two alarm outputs.
The four alarm inputs are low-level inputs with common ground (AIC). Use
insulated switch or relay to initiate alarms (open switches in normal operating
mode, closed switches cause alarm). The alarm switch connection can be toggled between active open and active closed. This is further described in the
OM-Online User Manual and the Advanced WRH OMS User Manual.
The alarm input voltage ratings, related to ground (AIC), are: Vinmax= 5.5V,
Vinmin= –0.5V
The four alarm inputs are connected to the following pins:
Pin 14 AI1 External alarm input 1 - EAL1
Pin 15 AI2 External alarm input 2 - EAL2
Pin 7 AI3 External alarm input 3 - EAL3
Pin 8 AI4 External alarm input 4 - EAL4
Pin 6 AIC Ground.
See also the P28 door switch port below.
Two alarm outputs are 1 pole closing and 1 pole opening relay outputs insulated from each other. Maximum ratings, related to ground or any other alarm
terminal, are 50V AC / 60V DC. The alarm outputs are defined as follows:
Pin 9 and 1 AO1 and AO8 Closed when operating, otherwise open.
Pin 10 and 2 AO6 and AO7 Open when operating, otherwise closed.
Pin 11 and 3 AO2 and AO5 Closed at alarm state, otherwise open.
Pin 12 and 4 AO3 and AO4 Open at alarm state, otherwise closed.
P28
Door switch port - Normally, alarm input AI4 is used for WRH door opening
alarm EAL4 which is arranged using an optional door switch. Signal AI4 and
AIC are thus available also in the P28 connector, to which the door switch is
connected. It is located on the DIA to the left in the cabinet. The EAL4 door
switch alarm is activated 10 – 30 seconds after the cover has been opened.
P34
WLI Port (8-pin RJ45 female) - Used for the WLI network (R2R). It is located on
the DIA to the left in the cabinet.
P36
WLI Port (5-pin male) - Used for the WLI network (IP or R2R). It is located on
the DIA to the left in the cabinet. Connecting P111 or P112 on a FON to this
port, an FLI network is interconnected to a WLI network (IP or R2R) making all
the included WRHs in both the networks accessible.

Installation
Introduction
This chapter contains unpacking, inspection and installation instructions for installing and
powering up the WRH.
Site Survey
Powerwave recommends that a site survey be performed prior to equipment ordering or
installation. Performing a detailed site survey reduces or eliminates installation and turn-up
delays. Pay particular attention to power plant capacity, cooling needs, floor space, and RF/
DC cabling/breaker requirements. Cabinet dimensions, clearance dimensions, and weights
are listed in Chapter 5.
Unpacking and Inspection
This equipment has been operated, tested, and calibrated at the factory. Carefully open
containers to remove equipment. Retain all packing material that can be reassembled in the
event unit must be returned to the factory. Perform the following steps:
• Visually inspect equipment for damage that may have occurred during shipment. If possible, in the presence of the delivery person.
• Check for evidence of water damage, bent or warped chassis, loose screws or nuts, or
extraneous packing material in connectors.
If equipment is damaged, file a claim with the carrier once the extent of any damage is
assessed.
If equipment must be returned to factory, please contact factory for a Return Material
Authorization (RMA). See Chapter 4.
WRH Location
The WRH is designed with a weather proof outdoor cabinet that can be mounted without any
kind of shelter from rain, snow or hail. The same unit can be installed indoors. A preferable
site for the WRH is a location free of obstructions, easily accessable and allows for proper airflow and ventilation.
If a WRH is installed outdoor and can be exposed to direct sunshine, it is essential that air
can circulate around the WRH with no obstacle. The operating temperature must not exceed
131°F (55°C). A shelter can be used to shade the WRH from direct sunshine.
Never open a WRH when rain, snow, hail, high humidity or high winds are present unless
some kind of temporary shelter can be erected. Limitations for very bad weather are found in
the next section.
Mounting
The WRH is easy to mount using the provided mounting bracket, which has 9/16” (14mm)
holes for 3/8” (10mm) or 1/2” (12mm) fixing screws. Clamps with C-C measures of 3.5”
(90mm), 5.3” (135mm), 5.7” (144mm), 8.1” (205mm), 9.8” (250mm), and 11.8” (300mm) can
be used as well. The vertical C-C measure for these are 16.2” (411mm). There is a 9/16”
(14mm) single hole in the middle of the mounting bracket, marked ‘A’ in the figure, which is
intended for a locking screw to lock the bracket into place.

Connections
This section describes general examples of how to connect the input and output ports on the
WRH.
Main Power and Grounding
Local regulations need to be followed for the main power connection. WRHs are approved in
accordance with EN and UL/cUL regulations. This is, however, only valid if a classified power
cord is used. For the WRH to meet these regulations you must select one of the following
classified and approved cord types:
• EN – H 05 W5 - F HMR
• UL – AWM Style 2587
• CSA– AWM 1 A/B 11 A/B
For outdoor use, the power cord should meet at least IP65 encapsulation requirements. Do
not turn the main power on until you are ready to commission the WRH
WARNING: For WRHs supplied from the main power source, the main outlet must be grounded.

Alarms
Alarm signals from external sensors are received by an ALI or RCI which forwards them to
the CU. The RCI is used if the WRH has an RCU, otherwise the ALI is used. The software on
the CU can activate acoustic or visual alarms or direct the alarm to the P33 alarm port for
forwarding via an RCU to an OM-Online or OMS workstation. Alarms can also be handled by
the FON. Alarms can be configured from an OM-Online or OMS workstation.
External Alarm
Burglary, fire or other external alarms can be handled by the WRH. External alarm sensors
and alarm signals are connected to the P33 alarm port located to the left in the cabinet, as
illustraated in Figure 3-8. The P33 alarm port is described in Chapter 2. The cable for this
installation is taken through a strain relief bushing at the bottom of the WRH cabinet.

Door Open Alarm
A door open alarm can be configured and installed in the WRH. This is arranged with a door
switch connected to P28, as illustrated in Figure 3-8.
Fiber Link Interface (FLI)
The FLI feature makes it possible to interconnect WRHs. By using an RF distribution fiber
network, no wire or other communication device is required.
Wire Link Interface (WLI) Network (IP to R2R)
Two types of WLI networks are available for the WRH: Internet Protocol (IP) and a Repeaterto-Repeater Link (R2R).
The network cables are connected to the P34 or P36 WLI ports on the DIA PCBA as
illustrated in Figure 3-9. The cables can either be interconnected at the P1 terminal on the
connector PCBA located to the right in the cabinet or to both P34 and P36.
Any cable type can be used for indoor installations. For outdoor installations, the Li 2YC11Y,
2x2xAWG24/222, non-halogen, Metrofunkkabel-Union cable type is recommended. Use
strain relief bushings or connectors at the bottom of the WRH. If the link cable between two
WRHs is longer than 25 meters, an RS-485 WRH is required as illustrated Figure 3-10.

RCU for Radio Communication
The RCU antenna for a radio modem is connected to the BS antenna via the uplink DC,
provided the RCU and the WRH operate in the same cell system. Otherwise, the modem
must have a separate antenna. Data is transferred between the WRH and the RCU via the
P130 modem port on the RCI or FON. The RCU is also powered via the same port and has a
battery with enough capacity to send a number of alarms if a main power failure occurs.
RCU for Telephone Line Communication
The land line version uses a telephone line connected to a terminal block on the RCU. A free
strain relief bushing at the bottom of the WRH is used for the external telephone line cable.
Repeater-to-Repeater Link (R2R)
This section briefly describes the R2R network. Node configuration for the R2R network is
described in the OM-Online User’s Manual. The R2R network is a Powerwave specific
network that can handle up to 13 nodes, one or several of which being a gateway for
communication with OM-Online or OMS via modem.
Sliding Window (SLW) is a Powerwave specific protocol developed for the R2R network. The
SLW protocol and the IP protocol do not support each other and they cannot be mixed in any
node.

Figure A-1 Standard WRH Block Diagram
Figure A-1 illustrates a single band WRH block diagram. The TX signal from the BTS is
converted to an optical signal at a FON within a BMU or OCM and fed to the WRH via a fiber
optic cable. The FON in the WRH converts the fiber optic signal back to RF. It also supervises
the signaling and reports errors via the RCU connected to the CU. The RF signal enters the
WBA at P1101. Amplification occurres in the LNA and the additional amplifier stages followed
by controllable attenuators. The signal exits the WBA on P1401 and enters the PA at P4
where it is amplified and fed to the DPX.
If a BA is installed, the signal goes through it before being fed to the DPX, boosting the output
DL signal from the PA by typically 6dB. The amplified output signal passes the DPX before it
is fed to the service antenna.
The uplink signal path is located on the same WBA but has no PA or BA stage. An optional
LNA can be used.

Figure A-2 WRH-V Block Diagram
Figure A-2 illustrates a block diagram the WRH-V. The WRH-V is always fed by a BTS via
either a BMU or an OCM. The TX signal from the BTS is converted to an optical signal in a
BMU or OCM and fed to the WRH-V via a fiber optic cable. The optical signal is received by
the FON and converted to an RF signal. The FON supervises the signaling and reports errors
via the RCU connected to the CU.
The RF signal enters the WBA at P1101, is amplified in a LNA and is then further amplified in
amplifier stages followed by controllable attenuators. The signal exits the WBA on P1401 and
enters the PA at P4 where it is amplified and fed to the DPX. The signal then goes through an
MCPA before being fed to the DPX. The amplified output signal passes the DPX before it is
fed to the service antenna.
The uplink signal path is located on the same WBA but has no PA or MCPA stage. An
optional LNA can be used.
