All rights reserved.Powerwave Technologies and the Powerwave logo are registered trademarks.Powerwave Technologies Inc. reserves the right to make changes to the documentation and equipment, includ-ing 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 con-ditions 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 accor-dance 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, espe-cially 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 environ-ment. 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 RequirementAll Powerwave apparatus introduced on the Canadian market meet all requirements of the Canadian Interfer-ence-Causing Equipment Regulations. The -20dB bandwidth at 1900 MHz band is 80 MHz. The -20dB band-width at the 850 MHz is 34 MHz.Powerwave Technologies Inc., 1801 East St. Andrew Place, CA 92705 Santa Ana, USA.Phone +1 714 466 1000 – Fax +1 714 466 5800 – Internet www.powerwave.com

044-05251 Rev A 1-1Chapter 1Product DescriptionIntroductionThis manual contains information and procedures for installation, operation, and maintenance of the Wideband Radio Head (WRH). The manual is organized into chapters as follows.Scope of ManualThis 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.SafetyIt 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 technician.• 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 Head1-2 044-05251 Rev A• 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 RadiationSafe 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.AntennasTo 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 SystemsInstallation 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 ExposureThe 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 power800/900 MHz 4.5W/m²1800/1900 MHz 9.0W/m²2100 MHz 10.0W/m²For antennas larger than 20cm the maximum radiation power can be calculated by using the following formula:Electrostatic 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.S = Radiation power in W/m²P = Output power in Wr = Distance between antenna and human in metersSP4πr2××--------------------=
Wideband Radio Head Overview044-05251 Rev A 1-3OverviewFigure 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.WRHThe 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.WRH-VThe 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 Head1-4 044-05251 Rev AChassis DesignThe 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 OverviewA 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 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 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.
Wideband Radio Head Overview044-05251 Rev A 1-5Figure 1-2 CU PCBADistribution 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. Figure 1-3 DIA PCBALow 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.Figure 1-4 LNADuplex Filter (DPX)DPXs are located on the metal cover sheet in the upper part of the cabinet. Service and donor DPXs are identical.ALLGON INNOVATIONSWEDEN M105 R61PARKINGFOR W5W58P27 W6B 101P33ALARMP23LNAUP-LINKP32MODEMAUX1P28DOOR596111611M->SP11P348915P2615 16S->M12389P365X0AX0B2V2 116P12 P13111161616P4P5P6cbacbacbacba1P2321ba116P316 116P141V111111461156915216124585P35P21PSU610P31PCP29P24P25GND76V6LNADOWN-LINKLEDP2212V6BP27P26P23XOAXOBP28P4 P5 P6 P2 P3 P31 P21 P35 P33P32P11 P12 P13 V1P14 P22P29P34 V2P36V6GNDP25P24

Wideband Radio Head Overview044-05251 Rev A 1-9Fiber Optic Distribution NetworksFiber 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.Figure 1-9 Fiber Optic Star ConfigurationMulti-Operator ConfigurationsMulti-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.Figure 1-10 Multi-operator SystemBMU WRHWRHWRHWRHBTS RF Operator 1Operator 2Sector 1Sector 1Sector 2Sector 2OCMRCMRCMPOIPOIPOIPOI

044-05251 Rev A 3-1Chapter 3InstallationIntroductionThis chapter contains unpacking, inspection and installation instructions for installing and powering up the WRH.Site SurveyPowerwave 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 InspectionThis 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 possi-ble, 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 LocationThe 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. MountingThe 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.
Mounting Wideband Radio Head3-2 044-05251 Rev AFigure 3-1 Mounting bracketNormally, the WRH is mounted on a wall, pole, or mast.

Connections Wideband Radio Head3-4 044-05251 Rev AAfter installing the mounting bracket, hang the WRH on the upper supports, as illustrated in Figure 3-5. Tighten the upper and lower mounting screws to secure it into place using the 6mm hex socket 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.Figure 3-5 Attaching the WRH to the bracketConnectionsThis section describes general examples of how to connect the input and output ports on the WRH. Main Power and GroundingLocal 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/BFor 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 WRHWARNING: For WRHs supplied from the main power source, the main outlet must be grounded.
Wideband Radio Head Connections044-05251 Rev A 3-5Fiber Optic and RF ConnectionsFiber 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 ProcedureWRHFigure 3-6 illustrates the cables and connections for a standard WRH.Figure 3-6 WRH Cable ConnectionsStep Action1 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.

044-05251 Rev A A-1Appendix ABlock DiagramsIntroductionThis appendix describes the main signals paths for the WRH.Standard WRHFigure 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.Figure A-1 Standard WRH Block DiagramWDMFOUDXDXDPXDPXWBAWBADLDLULUL LNALNAPAPATo/FromOCM orBMURCURCIPSU CUFONALI ToExternal alarmsBABA850 MHzTX0/RX01900 MHzTX0/RX0
WRH-V Wideband Radio HeadA-2 044-05251 Rev AWRH-VNon-DiversityFigure 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 MCPA 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.Figure A-2 WRH-V Block Diagram - Non-DiversityWDMFOUDXDXDPXDPXWBAWBADLDLULUL LNALNAMCPAMCPATo/FromOCM orBMURCURCIPSU CUFONALI ToExternal alarms850 MHzTX0/RX01900 MHzTX0/RX0
