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 eq u ipm e nt 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 damage and possible overload.

Federal Communications Commission (FCC) This device complies with the technical standards gove rning mo bile 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 requ ires carrier consent under FCC rules. T his 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 (iDEN800 and iDEN900) of the FCC Rules depending on the band of operation. Changes or modifications not exp ressly 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 Requirements All Powerwave apparatus introduced in the Canadian mar ket meet all requirements of the Canadian Interfere nce-Caus-

ing Equipment Regulations. The -20dB bandwidth at 190 0 MHz band is 80 MHz. The -20d B bandwidth at 1 900+G MHz band is 77.4 MHz. The -20dB bandwidth at the 700 MHz is 23.5 MHz. The -20dB bandwidth at the 700 MHz is 23.5 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, e specially 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 Technologies Inc., 1801 East St. Andrew Place, CA 92705 Santa Ana, USA.

Safety

Any personnel involved in installation, operation, or service of units included in a Powerwave Distributed Antenna System (DAS) must understand and follow the points below.

❑ Powerwave Nexus FTs are designed to receive and amplify signals from one or more

base stations and retr 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 loc

❑ For outdoor use, the power cord shou ld meet at least IP6

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 voltag e that can cause

electric shock. Disconnect are to be followed when servicing such units. Only authorized service person n el ar e allowed to service units while the mains are connected.

❑ When opened, the Nexus FT cover must be secured. Otherwise, the cover can be

Human Exposure to RF Radiation

Safe distances must be kept when working around antennas. The follo wing parag raphs 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 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 p 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 standar d with the purpose to protect ba se stations from noise and other performance dropping effects.

Distribution PCBA (DIA)

The DIA is the core distribution PCBA to which all othe

r 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 mounti ng location for the CU, ALI and RCIs, if used.

Control Unit PCBA (CU)

Figure 1-3 shows the CU, which is the core microprocessor controller in the WRH and is connected to P2 on the DIA. 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 suc h as gain con t rol 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.

Fiber Optic Distribution Networks

Fiber optic networks are setup identically to da ta networks. Nexus FTs are connected in a sta r configuration as illustrated in Figure 1-7. 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 Nexus FTs. By using WDMs and Optical Splitters (OSPs) in the Nexus FTs, 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 Interconnect (POI) units and OCMs as illustrated in Figure 1-8. In this simple example, two operators have t wo sectors each. Each s ector is connected to a POI and then to a RCM. The RCM is interconnected with an OCM via co axial cab les. Th e com bined DL an d UL signals a re converted to optical signals in the OCM and then distributed to the Nexus FTs-V.

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 through OM-Online. Alarms can also be handled by the FON. Alarms are configured through OM-Online.

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 3-7. 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. Th is is arranged with a do or switch connected to pin 8 (AI4) on P28, as described in chapter 2. The location of P28 is shown in Figure 3-7.

Passive Intermodulation (PIM) Testing

PIM is the non-linear effect of passive RF components in a desired RF transmission ba nd. As higher percarrier 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:

❑ Anr ❑ Agilent ESG443 ❑ 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

❑ Installed and operational WRH unit ❑ Installed passive RF network under test ❑ Torque wrenches for DIN and N connectors

Two different types of setup are av Figure 3-10 shows PIM testing with two carriers over one WRH, an carrier over each of two WRHs.

The following PIM test uses the receive sensitivity an

d gain of the WRH under test to verify that the receive path is free of PIM noise. For PIM to be a problem at a particular site, TX signals must exist such that their products fall into the RX band using the formulae:

order product = (2 * f1) - f

and

order product = (2 * f2) - f

3-10 044-05251 Rev C

Nexus FT Commissioning

Where f1 and f2 are two TX signals entering a WRH. 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 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)

2 Set WRH UL gain to 60 dB and DL gain such that desired per carrier power is presented at output

port

3 Set Spectrum Analyzer to 100 kHz resolution bandwidth and view RX band at 3

frequency calculated in step 1 4 Loosen fastening screw in each corner on front cover of WRH under test, and open cover 5 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. 6 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.

7 Enable WRH TX signal. For details on using OM-Online, see OM-Online user manual 8 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 9 If a higher level of noise exists, disable the WRH TX signal and disconnect cable to DAS at bottom-

left outside corner

10 Connect low PIM load onto WRH Service antenna connector at bottom-left outside corner. Tighten

connectors securely

11 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

Remote Control 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 4-2.

The RCU is connected to P130 on either an RCI or FON. A jumper is required between pins 1 and 2 on 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 occurs.

RCU for Telephone Line Communication

The land line version uses a telephone line connected to a terminal block on the RCU. A free strain relief bushing at the bottom of the WRH is used for the external telephone line cable.

Return For Service Procedures

When returning products to Powerwave, the following procedures will ensure optimum response.

Introduction

This appendix describes the main signals paths for the WRH.

Non-Diversity

Figure A-1 shows the non-diversity block diagram configuration of the WRH. The WRH is always fed b y 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 o ptical signal is then receive d 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 sta 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 thro

ugh an LNA before entering the WBA.

Figure A-2 illustrates the diversity block diagram configuration of the WRH. With diversity installed, there are two paths on the UL instead of one. This require s an add itional FON fo r the a dded receive path signa l. 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.
