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 a standard WRH is for single carrier operation; for a WRH-V it is for multiple carriers.
As long as the composite power does not exceed the rated power (20W for North America), derating is not
required for mutiple carriers. For situations above that, 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 at 1900 MHz band is 80 MHz. The -20dB band­width at the 850 MHz is 34 MHz.

Changes which occur after the printing date may be incorporated by a complete manual revision or
alternatively as additions.

Chapter 1

Product Description

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.

• 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.

• A lithium battery is permanently mounted on the CU and FON PCBAs. Due to the risk
of explosion, this battery must only be removed from the board by an Powerwave
authorized service techni ci an .

• NiCd batteries are mounted on the FON PCBA. These batteries contain environmental
poisonous substances. If replaced, the old batteries should be taken care of as stated
in the local prescriptions.

Safety Wideband Radio Head

P

--

• 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.

• 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.

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:

FrequencyRadiation power

800/900 MHz 4.5W/m²
1800/1900 MHz 9.0W/m²
2100 MHz 10.0W/m²

For antennas larger than 20cm the maximum radiation power can be calculated by using the following
formula:

S = Radiation power in W/m²
P = Output power in W

Electrost at ic Discharge (ESD)

ESD can severly damage essential parts of the 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.

Wideband Radio Head Overview

Overview

Figure 1-1 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 dissipation. 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, T ACS, 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.

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 restricts the number of bands to one in the cabinet and one additional
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.

Overview Wideband Radio Head

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.

Inside 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 access. 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
downlink, and one associated PA or MCPA for the downlink. The cabinet can be equipped with up to
two WBAs along with two PAs supporting two bands or one MCPA supporting one band. 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 dowlink direction and reside in
positions 2 and 4.

Multi-Carrier Power Amplifier PCBA (MCPA)

Installed in the WRH-V only, the MCP A 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 2 through 4 in
the cabinet and 6 through 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.

Control Unit PCBA (CU)

The CU is the core microprocessor controller in the WRH and is connected to P2 on the DIA. It contains
a microprocessor, main memory, flash memory for the CU software, EEPROM memory for parameters,
memory for the event log and statistics, a REFO reference oscillator, ports for local and remote
communication, battery powered real-time clock, and MAC identity circuit. The CU supervises and
controls operational parameters such as gain control and channel handling, alarms, event log,
password and logon. The CU is also a control interface for OM-Online and OMS. Software for the CU
can be downloaded from OM-Online, either locally or remotely, or from OMS. It is located in the lower
right part of the shielded DIA frame.

Low Noise Amplifier (LNA)

LNAs are used on the uplink and are located at the top of the cabinet and the high cover, if equipped.
All coaxial connectors are SMA-type. Signals from the DPX output are fed to the LNA input connector
IN. OUT1 and OUT2 outputs feed the WBAs of the same signal direction. The signal level in these
connectors are +20dB referenced to the antenna input. Another output, OUT LOW, is an expansion
output for an additional LNA if the WRH is equipped in the cover part of the chassis. The gain to this
connector is +2dB. The +7V input is used for +7V supply from the DIA PCBA and ATT is a control signal
for a controllable attenuator in the LNA.

The WRH-V has a configuration similar to the standard WRH with the exception of a the MCPA that
boosts the output DL signal from the PA. The MCPA is located at positions 3 and 4 in the cabinet. The
MCPA requires an additional heat sink and is attached to the MCPA PCBA. A WRH-V can only be
equipped for one band in the cabinet and an additional band in a high cover. PCBA positions are
illustrated in the Figure 1-8 and a block diagram is located in Appendix A.

Wideband Radio Head Overview

Fiber Optic Distribution Networks

Fiber optic networks are setup identically to data networks. WRHs are connected is a star configuration
as illustrated in Figure 1-9. 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 1-10. 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 WRHs. Additional information is provided in the Fiber Optic Equipment
Operation and Maintenance Manual.

Controls, Indicators and Connectors

Two LEDs are located on the front cover to provide easy identification of a fault in the system. The
amber operation LED lights up approximately 15 seconds after the main power is switched on. When
the LED is steady, the WRH is ready for operation. The red alarm LED indicates a system error
alarms when flashing and a critical alarm when steady.

The External Alarm Port P33 is used for external alarm sensors and alarm equipment. The four alarm
inputs are low-level inputs with common ground (AIC). Use an 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. 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.
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.

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 materi al in conne ct or s.

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.

Chapter 3

Installation

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 accessible and allows for proper air-flow 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-inch (14mm) holes
for 3/8-inch (10mm) or 1/2-inch (12mm) fixing screws. Clamps with C-C measures of 3.5-inch
(90mm), 5.3-inch (135mm), 5.7-inch (144mm), 8.1-inch (205mm), 9.8-inch (250mm), and 11.8-inch
(300mm) can be used as well. The vertical C-C measure for these are 16.2-inch (411mm). There is a
9/16-inch (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.

wrench. Locking cylinders, used to prevent unauthorized removal of the repeater, can be inserted and
locked with a key after the lower screws have been tightened. Make sure the donor antenna, directed
towards the BTS antenna, and the service antenna, directed towards the area to be covered by the
WRH, are mounted and installed properly.

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.

Fiber Optic and RF Connections

Fiber optic and RF cable connections should be verified both internally and externally before
powering up the equipment. This section illustrates the general internal connections of the WRH and
WRH-V. Verify these connections with the as-built drawings and documents for your specific system
configuration. Table 3-1 lists the steps for external connections to the WRH.

Table 3-1 Cable Connection Procedure

Step Action

1 Connect the service antenna coaxial cable to the left in the cabinet using an N-type male connector.
2 Connect the fiber optic cable from the OCM or BMU to the fiber optic cable demark on the FOU.
3 Connect station ground.
4 Mount the main power plug to the main power cord and connect it to the PSU.

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 illustrated 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.

Main Power Breakdown Relay

To be able to distinguish PSU faults from power failure, a main power breakdown relay can be used.
This relay is not included in the WRH. It has to be mounted outside the WRH cabinet. The relay
intended for this purpose must fulfil the following specifications:

Closing time: Max. 30 milliseconds
Insulation coil/contact: Min. 4KV

A main power connected relay must also be in compliance with valid local regulations.

Table 3-2 Main Power Breakdown Relay Connection

Step Action

1 Connect a current less closed relay contact to pin AI1 and AIC on the P33 alarm connector, see Fig-

ure 3-11. Alarm is initiated by short-circuiting pin AI1 and AIC in the P33 port.
2 Connect the relay coil. It must be supplied from the same fuse as the WRH
3 After commissioning, select Mains Breakdown in the alarm configuration window in OM-Online or

OMS. Refer to the OM-Online User Manual

for packing materials.

Remote Con trol Unit (RCU)

The RCU provides remote control of Powerwave WRHs. It contains an integrated mobile phone,
modem and power supply backup. The RCU is installed in the bottom front of the cabinet, on top of
the PSU as illustrated in Figure 4-1.

The RCU is connected to P130 on either an RCI or FON. A jumper is required between pins 1 and 2
on the RCI if the P130 cable connector is disconnected. If a main power failure occurs, the unit has a
battery with enough capacity for sending a number of alarms.

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 occur s .

Introduction

This appendix describes the main signals paths for the WRH.

Standard WRH

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
occurs 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.

WRH-V Wideband Radio Head

WRH-V

Non-Diversity

Figure A-2 illustrates non-diversity block diagram configuration of 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, is amplified, and further amplified in amplifier stages followed by
controllable attenuators. The signal exits the WBA and enters the MCP A where it is amplified and 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 only has an LNA before entering the WBA.

Diversity

Figure A-3 illustrates the diversity block diagram configuration of the WRH-V. With diversity installed,
there are two paths on the UL instead of one. This requires an additional FON for the added receive
path signal. Signal flow is identical to the non-diversity version with the MCPA on the DL and LNAs on
the UL providing the additional amplification out of and into the WBA.
