Powerwave Technologies and the Powerwave logo are registered trademarks. Powerwave Technologies Inc. reserves the right to make changes to documentation and equipment, including but not limited to component substitution and circuitry changes. Changes that impact this document may be subsequently 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 Nexus FT 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 multiple carriers. For situations where regulatory requirements require reduced interference to adjacent band users, the rating would have to be reduced by 3 dB. 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 based on the power and fuse specifications in Chapter 5 of this manual. Power strips should, at a minimum, conform to this requirement to prevent equipment dam-

age and possible overload. Federal Communications Commission (FCC) This device complies with the technical standards governing mobile radio devices in accordance with FCC Rules. This device is intended to facilitate the reception and transmission of mobile radio devices in the cellular, PCS or other mobile services, and its operation by end users or others requires carrier consent under FCC rules. This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to CRF47 part 15 of the FCC rules. This equipment is also certified to CRF47 part 22 (cellular), part 24 (PCS), part 27 and part 90 (public safety) of the FCC Rules depending on the band of operation. Changes or modifications not expressly approved by Powerwave Technologies, Inc. for compliance could void the users 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 accor-

dance 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 Requirements All Powerwave apparatus introduced in the Canadian market meet all requirements of the Canadian Interference-Caus-

ing Equipment Regulations. The -20dB bandwidth at 1900 MHz band is 80 MHz. The -20dB bandwidth at the 850 MHz is 34 MHz. The output impedance of the unit referenced in this document is 50 Ohms. The -20dB bandwidth at IDEN 800MHz band is 26 MHz. The Manufacturer's 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. For example, at IDEN 800MHz band, 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. The input signal is optical so input impedance requirements are not applicable. European Requirements The Powerwave Nexus FT apparatus introduced in EU markets are certified to ESTI EN 300 609-4 (GSM900 and DCS1800) and ESTI EN 301 908-11 (WCDMA).

Powerwave Nexus FTs 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 Nexus FT 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. 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 Nexus FT. 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. Only authorized service personnel are allowed to service units while the mains are connected. When opened, the Nexus FT cover must be secured. Otherwise, the cover can be closed by the wind and cause your fingers getting pinched or your head being hit. When working on a Nexus FT on high ground, for instance on a mast or pole, be careful not to drop parts or the entire Nexus FT. Falling parts can cause serious personal injury. All RF transmitting units, including Nexus FTs, 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 a 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 disposed of as stated in the local prescriptions. The FON unit contains a Class 1M laser transmitter that emits 24 mW invisible laser radiation at 1550 nm during operation and is intended for a restricted location. Avoid direct exposure from a disconnected laser transmitter or fiber cord. For example, do not view directly with optical instruments (magnifiers) and do not view directly with non-attenuating optical instruments. The FON Unit has this label attached:

Do not power up the FON unit if a fiber cable is not connected to the fiber output UL port, or if a fiber cable is connected to the port but disconnected at the other end. Never look at the end of a fiber cable. The 1310nm and 1550nm laser light is not visible. Always use an instrument, such as a power meter, to detect signaling. 044-05251 Rev B vii Electrostatic Discharge (ESD) Nexus FT Human Exposure to 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 Nexus FT 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 Nexus FT 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:

Frequency Radiation power 800/900 MHz 1800/1900 MHz 2100 MHz For antennas larger than 20cm the maximum radiation power can be calculated by using the following formula:

4.5W/m 9.0W/m 10.0W/m S= P/(4r2) S = Radiation power in W/m P = Output power in W r = Distance between antenna and human in meters 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. viii 044-05251 Rev B Chapter 1 Product Description Introduction This manual contains information and procedures for installation, operation, and maintenance of The Nexus FT High Power Wideband Radio Head - in this manual, referred to as 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. Overview Figure 1-1 Powerwave WRH Radio Head Powerwave Nexus FTs work as bi-directional on-frequency amplifiers used to extend coverage into uncovered areas in wireless mobile systems such as base station fringe areas, tunnels, convention centers, airports and 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. 044-05251 Rev B 1-1 Overview Nexus FT Nexus FTs 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 and power levels are set using a PC running Powerwave OM-Online software which communicates with the Nexus FTs 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. Nexus FTs 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 Nexus FTs available. The WRH is a fiber fed system designed to provide a high 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. 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 Nexus FT, 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. Sub Unit Overview A number of amplifier PCBAs are individually shielded and located under a metal cover inside the Nexus FT. This cover can be opened outward for access. These amplifier PCBAs are of different types depending on the supported system. All of the Nexus FTs are built up with a number of sub units which are described in the following sections. Wideband Amplifier PCBA (WBA) Nexus FTs 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, shown in Figure 1-6, are assigned for a WBA. Multi-Carrier Power Amplifier PCBA (MCPA) 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, as shown in Figure 1-6. 1-2 044-05251 Rev B Nexus FT Overview Distribution PCBA (DIA) The DIA is the core distribution PCBA to which all other PCBAs and units connect in the cabinet with the exception of the PA. Figure 1-2 shows a DIA PCBA. A shielded metal frame on the DIA provides the mounting location for the CU, ALI and RCIs, if used.

The CU 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, a battery powered real-time clock, and a MAC identity circuit. It supervises and controls operational parameters such as gain control and channel handling, alarms, the event log, the password and the 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. It is located in the lower right part of the shielded DIA frame. Figure 1-3 CU PCBA 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. An example of an LNA is illustrated in Figure 1-4. All of the coaxial connectors are SMA-type. Signals from the DPX output are fed to the LNA input connector (IN). The OUT1 and OUT2 outputs feed the WBAs in the UL direction. The signal level at these connectors is +20dB referenced to the antenna input. The other output, OUT LOW, is an expansion output for an additional LNA if the WRH is equipped with a unit in the cover part of the chassis. 044-05251 Rev B 1-3 Overview Nexus FT The gain to this connector is +2dB. The +7V input is used for +7V supply from the DIA PCBA and the ATT connection is for the control signal for a controllable attenuator in the LNA. Duplex Filter (DPX) DPXs are located on the metal cover sheet in the upper part of the cabinet. Figure 1-4 LNA Fiber Optic Unit (FOU) The FOU is a metal plate mounted on top of the cover plate in the upper part of the Nexus FT. The FON and fiber optic connectors are mounted on the FOU. Figure 1-5 illustrates an FOU with the FON and fiber optic connectors mounted on the plate. It can also be configured with combiners, splitters, and Wave Division Multiplexers (WDMs) to obtain a desired combination of several branches with double or single fiber. DPX FON Figure 1-5 FOU in Nexus FT Fiber Optic Node (FON) The FON is the main part of the FOU. It is a bi-directional electrical/optical signal converter and a node in a fiber network. In addition, the FON has all the functionality included in the CU PCBA and contains battery backup. It has also functionality for:

Electrical and optical signal supervision Internal and external alarm handling RS232 interface for local PC control via an O&M software (OM-Online) Remote control via an O&M software (OM-Online or OMS) Interfaces for RCU and FLI Battery backup with charger There are two versions of the FON; one with three SMA ports (UL, DL and RX Mon) and the other with four SMA ports (UL, DL, RX Mon and TX Mon). The FON also has two optical ports for DL and UL fiber connections. Power Supply Unit (PSU) The PSU supplies DC power to all of the components in the Nexus FT. Remote Control Unit (RCU) The RCU is an optional communication unit for remote control of Nexus FTs via PSTN or RF modems. RCU types and details are described in Chapter 4. 1-4 044-05251 Rev B Nexus FT Overview Alarm Interface PCBA (ALI) and Remote Control Interface PCBA (RCI) The ALI handles alarms and alarm communication. It is replace with an RCI if an RCU is used and provides an interface between the CU and an RCU for remote communication via modem. The RCI also handles alarms and alarm communication. Either unit is located in the lower left part of the shielded DIA frame. Sub Unit Locations The MCPA is located at positions 3 and 4 in the cabinet. A WRH is equipped for one band in the cabinet and, if required, an additional band in a high cover. PCBA positions are illustrated in Figure 1-6 and a block diagram is located in Appendix A.

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 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 accessible and allows for proper air-flow and ventilation. If a WRH is installed outdoors and can be exposed to direct sunshine, it is essential that air circulates around the WRH with no obstacles. The operating temperature must not exceed 131F (55C). 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. 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 measurements 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 measurement for these is 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. 044-05251 Rev B 3-1 Mounting Nexus FT A 411 14 90 135 144 205 250 300 Figure 3-1 Mounting Bracket Normally, the WRH is mounted on a wall, pole, or mast.

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 Bracket 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 Nexus FTto 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. Verify these connections with the as-built drawings and documents for your specific system configuration. Table 3-1 lists the steps to add the external connections to the WRH. 3-4 044-05251 Rev B Nexus FT Connections Table 3-1 Cable Connection Procedure Step Action 1 2 3 4 Connect service antenna coaxial cable to left-outside DIN connection on cabinet Connect fiber optic cable from OCM or BMU to fiber optic cable demark on FOU Connect station ground to appropriate ground point in cabinet Mount main power plug to main power cord and insert into PSU WRH Figure 3-6 illustrates the cables and connections for the WRH. 1550 1310 Power connection Fiber Optic Connection Service Antenna Connection Ground Points Figure 3-6 WRH Cable Connections 044-05251 Rev B 3-5 Optional Connections Nexus FT Optional Connections Alarms Alarm signals from external sensors are received by an ALI or RCI which forwards them to the CU.

As higher per-

carrier transmit power levels are applied to duplexed passive RF networks, PIM becomes an increasingly significant factor in potential receiver desensitization. A PIM tester may be used on the RF network prior to turn-on and commissioning of the unit, but if a PIM tester is not available, the following may be used:

The specification for the maximum allowed PIM is -115 dBm per 100 kHz resolution bandwidth at rated output power. To test for PIM follow the steps listed in Table 3-4. Table 3-4 PIM Testing Procedure Step Action 1 2 3 4 5 6 7 8 9 10 11 12 If BTS signals are present, continue with step 2. Otherwise, connect two signal generators to OCM and set frequencies such that products are in relevent receive band (see equations above) Set WRH UL gain to 60 dB and DL gain such that desired per carrier power is presented at output port Set Spectrum Analyzer to 100 kHz resolution bandwidth and view RX band at 3rd order product frequency calculated in step 1 Loosen fastening screw in each corner on front cover of WRH under test, and open cover Verify the noise floor specification for the Spectrum Analyzer. If the noise floor is higher than or equal to -85 dBm/100 kHz, locate FON, disconnect UL cable from port P101 and connect SpectrumAnalyzer to the cable using an SMA female - female connector (noise limit becomes -115 dBm + 60 dB = -55 dBm). Continue with step 7. If noise floor is lower than -85 dBm/100 kHz, locate the FON card and connect the Spectrum Analyzer to P117 (noise limit becomes -115 dBm + 60 dB - 30 dB = -85 dBm). If the FON only has three RF ports on the left side, port P117 will not be available, so follow instructions listed in step 5. Enable WRH TX signal. For details on using OM-Online, see OM-Online user manual Using Spectrum Analyzer, measure noise level. If no noise exists above calculated limit in step 5

(-55 dBm) or step 6 (-85 dBm) above, as appropriate, then test is passed and no other action is necessary If a higher level of noise exists, disable the WRH TX signal and disconnect cable to DAS at bottom-

left outside corner Connect low PIM load onto WRH Service antenna connector at bottom-left outside corner. Tighten connectors securely Remeasure noise level. If no noise exists above calculated limit in step 5 (-55 dBm) or step 6 (-85 dBm) as appropriate, then DAS has a PIM issue. Tighen all connections in DAS with torque wrenches, replace any cripmed or severely bent cables, and retest. Repeat until all issues are solved Otherwise, if noise is higher than limit, WRH is defective and must be replaced. See Chapter 4 for Replacement procedures 3-10 044-05251 Rev B Chapter 4 Maintenance Introduction This chapter contains periodic maintenance and performance test procedures for the WRH.

Non-Diversity Figure A-1 shows the non-diversity block diagram configuration of the WRH. The WRH 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 via a fiber optic cable. The optical signal is then 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 goes through an LNA before entering the WBA.
