LNKA800 MODULES
Overview
Theory Of Operation
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, an LINKNET AMPLIFIER MODULE is very similar
to a regular two-way radio repeater. On Frequency Radio Repeaters 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.
These Modules are designed for indoor use only and are intended for mounting in a
standard EIA 19 inch rack. Modular design of LINKNET AMPLIFIER MODULE
circuitry allows for easy servicing, stocking of spares, adaptability and upgrade
ability.

In line with the versatility of the LinkNet Platform, it is possible to re-configure the
LNKA800 module in the field. For further information on the modification software
and the PC adapter, contact KAVAL WIRELESS TECHNOLOGIES by E-mail:

Configuration
TM
In line with the versatility of the LinkNet Platform, it is possible to re-configure the
LNKA800 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 Kaval
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:

De-Rating Chart
To maintain the FCC Spurious Emissions limit of -13 dBm maximum, for multiple
carriers it is necessary to de-rate their power level. For FM carriers, they need to be
de-rated as shown...
Number of Carriers
Power per Carrier
+37 dBm
+26 dBm
+24 dBm
+22 dBm
+20 dBm
+19 dBm
+18 dBm
+17 dBm
+16 dBm
10
+15 dBm
15
+13 dBm
20
+11 dBm
25
+10 dBm
30
+9 dBm
For complex CDMA, TDMA, GSM, etc. carriers, typically de-rate by a further 3 to 5
dB. Consult Kaval for more information.

Power On Self Test (POST)
Each system module automatically performs a self-diagnostics when inserted into
the system Card-cage. These tests determine that the unit is a) correctly installed in
the Card-cage and b) 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
your KAVAL WIRELESS TECHNOLOGIES Service Representative, (See
Warranty / RMA Procedures).
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.

Normal Operation
The LNKA800 Module has six LED’s on the faceplate:
1. OPERATING - Operating normally.
2. STANDBY – Under the control of the Control Module, the LNKC1900
Module has the ability to act as a duplex transmitter, sitting perpetually in
Stand by Mode waiting for the primary transmitter to fail. This LED should
be constant Amber. If a Fault should occur with the primary module, the
“Stand by” unit will immediately become the primary unit, at which time the
Stand by LED will be turned off and the LED’s will show an operating
Module.
3. TRANSMIT – No function on these Modules.
4. RECEIVE – No function on these Modules.
5. PROGRAM – This LED will be constant Amber when the unit is being reprogrammed by the Controller Module. This will signify that the unit is
powered on but unavailable for use.
6. FAULT – Red LED, If the internal diagnostics for the module detect a
problem, then this LED will remain on

Antenna Installation
•
•
•
•
•
DCM000000054
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 that 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 10 dB. 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 100
Watts maximum. Please consult Kaval Wireless for assistance as required. 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.
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. This is shown in the figure in the Introduction. The Indoor Antennae
are simple 1/4 Wavelength (0 dB Gain) types. They are used with KAVAL
WIRELESS 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. 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 Kaval Wireless
for assistance as required. These Antennae are to be installed such that no
person can touch the Antenna, or approach within 0.2 Meters.
ANTENNA INSTALLATION
WARNING
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.
