LinkNet™ LNKA RF MODULES z USER MANUAL DCM000000054 Printed: 03.12.15,10:19 Revision Date:12/15/03 4 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.

Module Specifications
LinkNet™ LNKA RF MODULES z USER MANUAL DCM000000054 Printed: 03.12.15,10:19 Revision Date:12/15/03 7 Software Set-up LNKA modules are shipped with the following factory set options: OPTION RANGE OF VALUES DEFAULT VALUEFrequency 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. In line with the versatility of the LinkNetTM Platform, it is possible to re-configure the LNKA module in the field. For further information on the modification software and the PC adapter, contact KAVAL WIRELESS TECHNOLOGIES by E-mail: info@kaval.com Configuration In line with the versatility of the LinkNetTM Platform, it is possible to re-configure 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 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: 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.

For FM carriers, they need to be de-rated as shown... Number of Carriers Power per Carrier 1 +37 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 For complex CDMA, TDMA, GSM, etc. carriers, typically de-rate by a further 3 to 5 dB. Consult Kaval for more information.
LinkNet™ LNKA RF MODULES z USER MANUAL DCM000000054 Printed: 03.12.15,10:19 Revision Date:12/15/03 9 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 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. 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.
LinkNet™ LNKA RF MODULES z USER MANUAL DCM000000054 Printed: 03.12.15,10:19 Revision Date:12/15/03 10 Normal Operation The LNKA Module has six LED’s on the faceplate: 1. OPERATING - Operating normally. 2. STANDBY – Under the control of the Gateway 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 re-programmed 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

LinkNet™ LNKA RF MODULES z USER MANUAL DCM000000054 Printed: 03.12.15,10:19 Revision Date:12/15/03 12 • 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 20 dBi. 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. 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. • 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 De-Rating Chart) to +28dBm 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. 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
