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 this equipment is for single carrier operation. For situations when multiple carrier sig-nals are present, the rating would have to be reduced by 3.5 dB, especially where the output signal is re-radi-ated 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 require-ment 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 is 80MHz.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.• 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 Chapter 1 - Product Description Chapter 2 - Controls and Indicators Chapter 3 - Installation Chapter 4 - Maintenance Chapter 5 - Specifications
Wideband Radio Head Safety1-2 044-05251 Rev Acoaxial 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 SignsThe following warning signs must be observed and be kept clean and readable.Beryllium oxideThis warning sign is applied on boards and units which contain beryllium oxide parts.This warning sign is applied at the bottom, inside the cabinet, below the power supply unit.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:BerylliumoxidehazardBERYLLIUM OXIDE(Toxic)used in equipmentsee instruction book

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).Radiation Safety DistancesThis section illustrates the safety distances to the antennas for some typical WRH configurations.Outdoor GSM 900MHzThe safety distance can be read to 0.75 meter in Figure 1-1 as the maximum radiation power is 4.5W/m2 for 900MHz.Indoor GSM 900MHzThe safety distance can be read to 0.035 meter for 4.5W/m2 (900MHz).Outdoor UMTS Standard High PowerThe safety distance can be read to 0.9 meter for 10W/m2 (2100MHz).WRH output power +33dBmFeeder loss –5dBAntenna gain +17dBiEquivalent Isotropic Radiated Power (EIRP) +45dBmWRH output power +22dBmFeeder loss –5dBAntenna gain +1dBiEIRP +18dBmWRH output power +38dBmFeeder loss –5dBAntenna gain +17dBiEIRP +50dBmSP4πr2××--------------------=

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.Figure 1-1 Safety distance to active antenna.WRH output power +24dBmFeeder loss –5dBAntenna gain +3dBiEIRP +22dBm101520253035400 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.045501.1 1.2 1.3 1.40.010.030.10.31.03.210.031.61004.5W/m2 (900MHz) 9W/m2 (1800MHz) 10W/m2 (2100MHz)Antenna output power in dBmAntenna output power in WSafety distance to antenna in meter
Overview Wideband Radio Head044-05251 Rev A 1-5OverviewFigure 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.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.
Wideband Radio Head Overview1-6 044-05251 Rev AWRH-VThe 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 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.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 OverviewA 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.

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.Figure 1-10 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 1-7. 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.Figure 1-11 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 pos-sible, 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 accessable 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” (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.

044-05251 Rev A A-1Appendix ABlock DiagramsIntroductionThis appendix describes the main signals paths for the WRH.Standard WRHFigure A-1 Standard WRH Block DiagramFigure 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.

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.
