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 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 FT Strand mount 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 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 CRF47 part 15 of the FCC rules. This equipment is also certified to CRF47 part 24 (PCS) of the FCC Rules depending on the band of operation. Changes or modifications not expressly approved by Powerwave Tech-

nologies, 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 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 commu-

nications. 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. 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 cellu-

lar, PCS or other mobile services, and its operation by end users or others requires carrier consent under FCC rules. Industry Canadian Requirements All Powerwave apparatus introduced in 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 output imped-

ance of the unit referenced in this document is 50 Ohms. The input signal is optical so input impedance requirements are not applicable.

Powerwave Nexus FT systems 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. 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. 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. 044-05320 Rev A vii DRAFT Electrostatic Discharge (ESD) Nexus FT Strand Mount 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 RM ORD 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 RM ORD 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 044-05320 Rev A DRAFT Chapter 1 Product Description Introduction This manual contains information and procedures for installation, operation, and maintenance of the Nexus FT Strand Mount repeater, referred to in this manual as the Nexus FT SM.

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 Powerwave Nexus FT SM repeaters 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 Nexus FT SM are made with N-type or 7/16" male connectors. Nexus FT SMs are microprocessor controlled. Operational parameters, such as gain and power levels are set using a PC running Powerwave OM-Online software which communicates with the Nexus FT SMs 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 FT SMs can be configured in many combinations depending on the wireless system, single or double system operation, and output power. 044-05320 Rev A 1-1 DRAFT Overview Nexus FT Strand Mount Chassis Design Enclosure The Nexus FT SM is housed in an aluminum enclosure, approved for outdoor use.

If possible, in the Check for evidence of water damage, bent or warped chassis, loose screws or nuts, or extraneous presence of the delivery person. 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. Nexus FT SM Location The Nexus FT SM 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 Nexus FT SM is a location free of obstructions, easily accessible and allows for proper air-flow and ventilation. If a Nexus FT SM is installed outdoors and can be exposed to direct sunshine, it is essential that air circulates around the Nexus FT SM with no obstacles. The operating temperature must not exceed 131F (55C). A shelter can be used to shade the Nexus FT SM from direct sunshine.. Mounting The Nexus FT SM is designed for mounting on a cable using the hangar clips attached to the top of the unit. 044-05320 Rev A 3-1 Figure 3-1 Cable Mounting DRAFT Connections Nexus FT Strand Mount 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. Nexus FT SMs 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 FT SM 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 Nexus FT SMs 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 Nexus FT SM. 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 Nexus FT SM. Table 3-1 Cable Connection Procedure Step Action 1 2 3 4 3-2 044-05320 Rev A DRAFT Nexus FT Strand Mount Connections Nexus FT SM Figure 3-6 illustrates the connections for the Nexus FT SM. Figure 3-2 Nexus FT SM Cable Connections 044-05320 Rev A 3-3 DRAFT Optional Connections Nexus FT Strand Mount Optional Connections 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 Nexus FT SM 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 through OM-

Online. Alarms can also be handled by the FON. Alarms are configured through OM-Online. Commissioning Before proceeding, carefully read the Safety section and check all connections made during the installation. To fulfill the IP65 weather protective requirements, ensure cable strain relief bushings are properly tightened. Also, ensure gaskets at cable inlets and on the cabinet are properly fitted and not damaged. A Nexus FT SM can be configured locally with OM-Online by connecting a standard serial cable from the COM port on the PC to the P31 PC port (RS-232) located to the right in the cabinet as shown in Figure 3-9. The P31 PC port is described in Chapter 2. Details on using OM-Online are described in the OM-Online User Manual. Initial Startup To complete the inital start-up of the Nexus FT SM, follow the steps listed in Table 3-3. Table 3-2 Initial Statup Procedure Step Action 1 2 3 4 Passive Intermodulation (PIM) Testing PIM is the non-linear effect of passive RF components in a desired RF transmission band. 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 following equipment is required to test for PIM:

Anritsu Site eMaster or equivilent RF Spectrum Analyzer Agilent ESG4432B or equivilent Multi- Signal Generator (or commissioned BTS) Guarateed/calibrated PIM load capable of handling 20W composite power Low-PIM RF cable adaptors such as N-N female , Din male to N femaile, DIN-DIN, SMA-SMA female, and N male to SMA female Installed and operational Nexus FT SM unit Installed passive RF network under test Torque wrenches for DIN and N connectors Two different types of setup are available, depeding on equipment availability and testing methods. Figure 3-10 shows PIM testing with two carriers over one Nexus FT SM, and Figure 3-11 shows PIM testing with one carrier over each of two Nexus FT SMs. 3-4 044-05320 Rev A DRAFT Chapter 4 Maintenance Introduction This chapter contains periodic maintenance and performance test procedures for the WRH.
