BDA1250 Equipment ManualDCM000000013  Kaval Telecom Inc. Page 5 of 172 INTRODUCTION2.1 Scope of the ManualThis manual covers the use, operation and installation of the BDA1250 Bi-directionalLine amplifier. It consists of nine sections described below:Section 1. FCC Notice: Note and warning.Section 2. Introduction: Scope of the manual and overview of BDA system application.Section 3. BDA1250 Amplifier description: Description and specifications of theBDA1250.Section 4. BDA Installation: Details procedures for installing of BDA1250.Section 5. Antenna Installation: Details procedures for installing antenna.Section 6. Maintenance and Troubleshooting: Recommendation for maintenance BDAand resolving BDA problem.Section 7. Standard Warranty: Warranty Schedule.Section 8. Product Service Procedure: Return Material Authorization procedure.Section 9. Ordering Parts and Accessories: Information ordering BDA parts andaccessories.2.2 “Off-the air” Amplifier System ApplicationThe Bi-Directional Amplifier is intended to extend Cellular coverage into areas withcoverage deficiency such as inside office buildings, shopping malls, hospitals etc. It isdesigned to be located independent of the donor site and must be equipped with its ownantenna systems - one to communicate with the donor site and the other(s) tocommunicate with portables in the shadow zone.A typical in-building coverage extension system is shown in Figure 1-2. The head-endsubsystem, namely Kaval bi-directional amplifier, is responsible for the amplification of bothincoming “off-the-air” downlink signal and outgoing uplink signals. The in-buildingdistribution antenna system comprises of Coaxial cable, Signal taps, splitters and antennas toextend coverage on every floor, basement and underground parking garage.
BDA1250 Equipment ManualDCM000000013  Kaval Telecom Inc. Page 6 of 17 Figure 1-2. Bi-Directional Amplifier in RF distribution SystemThis distributed antenna system is based on Kaval’s patented “Tapped Radiator” RFsignal distribution approach. The technology makes use of coaxial cable with SignalTaps strategically located and connected to Omni-directional ground plane antennas. Thistechnology offers flexibility in system design, installation and optimization. Once the RFcable backbone has been installed, additional signal taps and antennas can quickly andeasily be added to a live system, without the need to take the system out of service.Hence, new coverage areas can be added, or the system can easily be modified if thelayout should change (e.g. modernization retrofits or process modifications).BDA1250

BDA1250 Equipment ManualDCM000000013  Kaval Telecom Inc Page 12 of 174 BDA Enclosure Installation4.1 Preparation for the installation of BDA enclosuresa. Equipment and hardware required• Each BDA is carefully packaged for air shipment. Any damage incurred during thetransportation must be claimed from the shipper.• Make sure the following necessary equipment and hardware are available and undamaged.• 1 BDA1250 (supplied by Kaval)• Jumper cable (not supplied by Kaval)• AC adapter (supplied by Kaval)• Mounting hardware such as: Four washers and four bolts (not supplied by Kaval)b. Preparing the installation site• Make sure the mounting area is large enough to accommodate for the installation of theBDA1250 (5.6”Wx1.6”Hx8.3”D) and free airflow is available around the unit.• RF cables must be in place and labeled clearly as “Donor Cell Site” and “In-building”.4.2 Mounting the BDA EnclosureThe physical installation is accomplished by mounting the BDA1250 in false ceilings, closetsor on a vertical wall. Using four mounting holes on the enclosure (5.82” x 5.125”, see figure3-2) as a template insert four bolts to the wall. Make sure the bolts are capable of supportingat least 5 lbs4.3 Connecting the Coaxial cablesConnectors of the BDA are located on the front and back of the BDA1250 (see figure 3-2).RF cables can be connected to these connectors using jumper cables as follows.1. Connect one end of the first jumper cable to the BDA1250 connector marked“Outdoor”2. Connect the other end of the first jumper cable to the connector marked “Donor Cell3. Connect one end of the second jumper cable to the BDA connector marked “Indoor”4. Connect the other end of the second jumper cable to connector marked “In-building”cable
BDA1250 Equipment ManualDCM000000013  Kaval Telecom Inc Page 13 of 17 Figure 3-2. RF and DC Connections4.4 Connecting the Power CablesBDA1250 comes with AC adapter. Therefore an AC outlet providing 120 AC should beavailable with 4ft of the BDA1250. If AC outlet is to be installed, it is highly recommendedthat AC Power Wiring be performed by a qualified Electrician so as to ensure compliancewith all National and Local Electrical Wiring Regulations. Connecting power cables can bedone as follow:1. Locate the on/off switch on the front of the BDA1250. Turn the switch to the OFFposition.2. Locate a nearby AC outlet and connect AC adapter to the AC outlet.3. Connect the DC input jack of the AC adapter to the BDA12500.4. Make sure the adapter cable is neatly tugged away.5. Turn the BDA1250 power switch to the ON position. LED should be luminous toindicate the present of power.To OutdoorAntennaPower SwitchLEDDC PortTo IndoorAntenna
BDA1250 Equipment ManualDCM000000013  Kaval Telecom Inc Page 14 of 175 Antenna InstallationlAll Antenna Installation is to be performed by Qualified Technical Personnelonly.lAntenna Installation Instructions and locations below are for the purpose ofsatisfying FCC RF Exposure Compliance requirements.lThe Roof Top Antenna for linking to the Donor Site is a directional (high gain)Antenna fixed-mounted physically on the side or top of a building, or on a tower. TheAntenna Gain must be no more than 10 dBi. The Roof Top Antenna location should besuch that only Qualified Technical Personnel can access it, and that under normaloperating conditions no other person can touch the Antenna, or approach within 10meters of the Antenna.lThe In-Building Antenna connection is via a coaxial cable distribution system withSignal Taps at various points connected to the fixed-mounted Indoor Antennae. Thisis shown in the figure in the Introduction. The Indoor Antennae are simple 1/4Wavelength (0 dBi Gain) types. They are used with Kaval 12, 16, or 20 dB CableTaps. As such the maximum EIRP will be at the first Tapped Antenna, which will be12 dB below the maximum signal level of the BDA1250; +28 dBm, or 0.63 WattsEIRP. These Antennae are to be installed such that no person can touch the Antenna,or approach within 0.2 Meters.ANTENNA INSTALLATIONWARNINGALL ANTENNA INSTALLATION IS TO BE PERFORMED BY QUALIFIED TECHNICALPERSONNEL ONLY.ANTENNA INSTALLATION INSTRUCTIONS AND LOCATIONS ARE FOR THE PURPOSEOF SATISFYING FCC RF EXPOSURE COMPLIANCE REQUIREMENTS, AND ARE NOTOPTIONAL.ALL ROOF TOP ANTENNA INSTALLATION MUST BE SUCH THAT NO PERSON CANTOUCH THE ANTENNA, OR APPROACH CLOSER THAN 10 METERS.ALL IN-BUILDING ANTENNAE INSTALLATIONS MUST BE SUCH THAT NO PERSONCAN TOUCH THE ANTENNAE, OR APPROACH CLOSER THAN 0.2 METERS.
