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.

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 4.5W/m²
1800/1900 MHz 9.0W/m²
2100 MHz 10.0W/m²

For antennas larger than 20cm the maximum radiation power can be calculated by using the following formula:

S = Radiation power in W/m²
P = Output power in W
r = Distance between antenna and human in meters

S= P/(4

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. The UL ouput signal is connected to the ORD via RF coax cable, converted to light, and sent via
fiber toward the BTS.

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.
