Theory of Operation
1 Introduction
This manual contains information and procedures for installation, operation, maintenance, and
troubleshooting of the LNKA Modules. The manual is organized into the following chapters:
Chapter 1 Theory of Operation Chapter 3 Antenna Installation
Chapter 2 Operation Chapter 4 Return for Service
1.1 Overview
A LinkNet Amplifier Module is a Broad-Band Digitally Controlled Class-A Amplifier. The most common
LinkNet Amplifier Module applications are the extension of above ground signals into buildings, tunnels,
vehicles or the extension of radio coverage patterns into outdoor shaded areas such as deep valleys.
From an applications standpoint, a LinkNet Amplifier Module is very similar to a regular two-way radio
repeater. LinkNet Amplifier Modules can be combined using regular two-way radio multicoupling or
duplexing equipment and have input and output signal characteristics to those of regular transmitters
and receivers. The one special consideration in LinkNet Amplifier Module systems is that of input to
output antenna isolation. This must be carefully engineered for each installation.
LinkNet Amplifier Modules are designed for indoor use only and are intended for mounting in a
standard EIA 19 inch rack. The Modular design of LinkNet Amplifier Module circuitry allows for easy
servicing, stocking of spares, adaptability and upgrade ability.

Operation
2 Introduction
This chapter contains information for the standard operation of the LNKA Modules.
2.1 Software Set-Up
The LNKA modules is shipped with the following factory set options:
Table 3 LNKA Factory Set Options
OPTION RANGE OF VALUES DEFAULT VALUE
Frequency See Model Chart Order Specific
Gain +34 to +84 dB +34 dB
AGC +15 to +30 dBm or Disabled +30 dBm
Module Enabled On / Off On
Default values may be changed when an order is placed. Check your order confirmation (shipped
with modules) for customized values.
2.2 Configuration
In line with the versatility of the LinkNetTM Platform, it is possible to reconfigure the LNKA module
in the field, either with a Personal Computer (PC) or via the optional Control Module. To use a PC
it is necessary to have a Powerwave CAB000000057 control cable to connect between the
appropriate module's DB15 connector on the back of the card-cage and the standard DB9 RS232
connector on the PC. On the PC a terminal emulation program such as HyperTerminal is used to
communicate to the LinkNet Module. The settings are 9600 baud, 8 bits, no parity, and 1 stop bit.
Commands are one or two words followed by pressing Return. Commands may be given in upper
or lower-case. Available commands are:
ACCESS USER: Required as a simple password to gain access to customer settable
parameters and diagnostics. This will time-out after 10 minutes, and may
have to be re-typed.
HELP or ?: Displays a list of available commands.
LIST: Displays current settings and status faults, etc.
VER: Display the current version of software.
ENABLE 1 or 0: Enables or disables the module.
GAIN ###: Displays or sets the module gain (in tenths of a dB).
AGCTHRESH ###: Displays or sets the AGC level (in tenths of a dBm).
AGCEN 1 or 0: Enables or disables AGC.
Please consult Powerwave Technologies Inc. for further support.
Derating Chart
2-2 DCM000000054 Rev Q
2.3 Derating Chart
To maintain the FCC Spurious Emissions limit of -13 dBm maximum, for multiple carriers it is
necessary to derate their power level. For FM carriers, they need to be derated as shown:
Table 4 Power Derating Chart
Number of Carriers Power per Carrier
1 +33 dBm
2 +26 dBm
3 +24 dBm
4 +22 dBm
5 +20 dBm
6 +19 dBm
7 +18 dBm
8 +17 dBm
9 +16 dBm
10 +15 dBm
15 +13 dBm
20 +11 dBm
25 +10 dBm
30 +9 dBm
NOTE: The rated mean output power for Industry Canada RSS131 is +29 dBm.
For complex CDMA, TDMA, GSM, etc. carriers, typically de-rate by a further 3 to 5 dB. Consult
Powerwave Technologies for more information.
2.4 Power On Self Test (POST)
Each module automatically performs a self-diagnostics when inserted into the system card-cage.
These tests determine that the unit is correctly installed in the card-cage and not damaged in transit.
•
•
•
•
All six of the LED’s on the front panel will flash 3 times.
If the LED’s do NOT flash three times, then remove the module, check the power source,
and re-insert the module, (See Installation Instructions).
If the card is “OK” the LED’s will continue normally (See Normal Operation).
If there is a fault, then the Red Fault LED will remain on. If this occurs, contact
Powerwave Technologies Inc. (Refer to Chapter 4 Return for Service).
Note! The Power On Self Test is Not an RF test, it only verifies that there is power to the unit and
that the logical circuitry is functioning.
Fault Indications
2.5 Fault Indications
Each module continuously performs internal diagnostics. If a problem is detected it will activate its Red
Fault LED and Fault Relay. Faults detected include:
•
•
Over Temperature
Misc. Internal Faults
Detailed faults are detected by the optional gateway module. Details may also be determined via
the module's control port connector and an RS232 connected Terminal Emulator using the LIST
command.
2.6 Normal Operation
The LNKA Module has six LED’s on the faceplate:
OPERATING - LED will flash GREEN when RF Data is present and unit is
operating normally.
STANDBY – Under the control of the Gateway Module.
TRANSMIT – No function on these modules.
RECEIVE – No function on these modules.
PROGRAM – Constant Amber when the unit is being re-programmed by the
controller module. This will signify that the unit is powered on but unavailable for
use.
FAULT – Constant Red if the internal diagnostics for the module detects a
problem.

Antenna Installation
3 Introduction
This chapter contains antenna installation and warning information for the LNKA Modules.
3.1 Antenna Installation
•
•
•
•
•
•
All antenna installation to be performed by qualified technical personnel only.
Antenna installation instructions and locations below are for the purpose of satisfying
FCC RF Exposure Compliance requirements.
Note! If multiple LinkNet™ Modules are used, the Instructions below apply to the
composite power output of all Modules when transmitting simultaneously.
The Roof Top Antenna or Antennae for linking to the Donor Site(s) is/are directional (high
gain) Antennae, fixed-mounted physically on the side or top of a building, or on a tower.
The Antenna Gain must be no more than 20 dBi.
Note! If multiple LinkNet™ Modules are used with output combiners into any one
Antenna, and/or multiple Antennae are used on one Roof Top, then the sum of
composite powers into all Roof Top Antennae must not exceed 20 Watts maximum.
The Roof Top Antennae location should be such that only qualified technical personnel
can access it, and that under normal operating conditions no other person can touch the
antenna, or approach within 10 meters of the antenna.
For the Cellular Uplink Band (824-849 MHz) the Roof Top Antenna or Antennae for
linking to the Donor Site(s) has the added restriction that the Effective Radiated Power
(ERP) must not exceed 7 Watts (+38 dBm). Thus, if the AGC is set (as per the Carrier
Derating Chart) to +28 dBm as an example, the maximum allowed antenna gain must be
no more than 10 dBi.
The In-Building Antenna connection is via a coaxial cable distribution system with signal
taps at various points connected to the fixed-mounted Indoor Antennae. The Indoor
Antennae are simple 1/4 wavelength (0 dB Gain) types. They are used with Powerwave
Technologies’ 12, 16, or 20 dB cable taps. As such the maximum EIRP will be at the first
tapped antenna, which will be 12 dB below the maximum signal level of the LinkNet™
(+40 dBm); +28 dBm, or 0.63 Watts EIRP. These antennae are to be installed such that
no person can touch the antenna, or approach within 0.2 Meters.
Note! If multiple LinkNet™ Modules are used with output combiners, then the composite
power output of all Modules transmitting simultaneously must meet this maximum
EIRP requirement.
Please consult Powerwave Technologies Inc. for assistance as required.
FCC Information to Users
ANTENNA INSTALLATION
CAUTION
ALL ANTENNA INSTALLATION IS TO BE PERFORMED BY QUALIFIED TECHNICAL
PERSONNEL ONLY.
ANTENNA INSTALLATION INSTRUCTIONS AND LOCATIONS ARE FOR THE PURPOSE
OF SATISFYING FCC RF EXPOSURE COMPLIANCE REQUIREMENTS, AND ARE NOT
OPTIONAL.
ALL ROOF TOP ANTENNA INSTALLATION MUST BE SUCH THAT NO PERSON CAN
TOUCH THE ANTENNA, OR APPROACH CLOSER THAN 10 METERS.
ALL IN-BUILDING ANTENNAE INSTALLATIONS MUST BE SUCH THAT NO PERSON CAN
TOUCH THE ANTENNAE, OR APPROACH CLOSER THAN 0.2 METERS.
3.2 FCC Information to Users
• This equipment has been tested and found to comply with the limits for a Class A digital
