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 damage 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) and part 90 (iDEN800 and iDEN900) 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 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 market meet all requirements of the Canadian Interference-Causing 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 multi carrier operation. For situations when multiple carrier signals are present,
the power rating per carrier would have to be reduced. For example, the power rating per carrier should be reduced by 3dB if two
carriers are present. A special situation can exist where the power rating per carrier will need to be reduced further due to high crest
factor (peak power) waveforms. Consult your Powerwave representative for these situations. 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. The term “IC:” before the radio certification number only signifies that Industry of Canada technical specifications were met. Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device.
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).

Preface
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 FT Rack Mount Radios (RMR) are designed to receive and amplify
signals from one or more base stations and retransmit the signals to one or more mobile
stations. They also act the other way round, that is to receive signals from one or more
mobile stations, then amplify and retransmit the signals to the base stations. Powerwave
Nexus FT RMR systems must be used exclusively for this purpose and nothing else.
❑
Units supplied with power 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 FT RMRs, 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.
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 RMR 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 RMR output power, antenna gain, and
transmission devices such as cables, connectors, splitters and feeders. Also, 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
4.5W/m²
9.0W/m²
10.0W/m²
For antennas larger than 20cm the maximum radiation power can be calculated by using the following formula:
S= P/(4πr2)
044-05207 Rev A
S = Radiation power in W/m²
P = Output power in W
r = Distance between antenna and human in meters
iii
Electrostatic Discharge (ESD)
Nexus FT RMR
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.

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
The RMR is a repeater designed to be part of a Distributed Antenna System (DAS). The components are
mounted on a 19” rack and are intended for use in an in-door, temperature controlled environment.
As part of a DAS, the RMR extends 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) and to/from Mobile Stations (MS) with both directions being
served simultaneously.
The RMR unit is a dual wide band, bi-directional, RF amplifier with two separate donor ports and a common
(duplexed) service port per band. It connects to an Optical to RF Distribution Unit (ORD) where RF signals are
combined or split and converted to an optical signal in the Uplink direction. In the Downlink direction, optical
signals are converted to RF and split to RF outputs. Two separate full duplex fibers handle signal transport
between the BTS Master Unit and the ORD. The DL signal and the UL signal combine onto one optical fiber
through a Wavelength Division Multiplexer (WDM). Wide band 4-way combiners handle RF splitting and
combining.
A Wireless Portal module distributes the DL/UL signals to/from the DAS.
The RMR is microprocessor controlled with alarm and operational status LEDs visible on the front. Cooling is
provided through forced air fans. Operational parameters, such as gain and power levels are set using a PC
running Powerwave OM-Online software which communicates with the RMRs either locally or remotely via
modem. Remote operation can be accomplished via PSTN or a GSM net. The Operation and Maintenance
System (OMS) provides for Network Operations Center (NOC) configuration and alarm monitoring.
The RMR is a fiber fed system designed to provide a high output power level and comes equipped with a Multi
Carrier Power Amp (MCPA) in the downlink path. The MCPA is located in the RMR cabinet along with a power
supply.
