BDA1250 Equipment Manual

1 FCC NOTICE

Note:

This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, If not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case the
user will be required to correct the interference at his own expense.

Warning:

Changes or modifications not expressly approved by Kaval Telecom Inc. could void the
user’s authority to operate the equipment.

2 INTRODUCTION

2.1 Scope of the Manual

This manual covers the use, operation and installation of the BDA1250 Bi-directional
Line 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 the

BDA1250.

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 BDA

and 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 and

accessories.

2.2 “Off-the air” Amplifier System Application

The Bi-Directional Amplifier is intended to extend Cellular coverage into areas with
coverage deficiency such as inside office buildings, shopping malls, hospitals etc. It is
designed to be located independent of the donor site and must be equipped with its own
antenna systems - one to communicate with the donor site and the other(s) to
communicate with portables in the shadow zone.

A typical in-building coverage extension system is shown in Figure 1-2. The head-end
subsystem, namely Kaval bi-directional amplifier, is responsible for the amplification of both
incoming “off-the-air” downlink signal and outgoing uplink signals. The in-building
distribution antenna system comprises of Coaxial cable, Signal taps, splitters and antennas to
extend coverage on every floor, basement and underground parking garage.

BDA1250

This distributed antenna system is based on Kaval’s patented “Tapped Radiator” RF
signal distribution approach. The technology makes use of coaxial cable with Signal
Taps strategically located and connected to Omni-directional ground plane antennas. This
technology offers flexibility in system design, installation and optimization. Once the RF
cable backbone has been installed, additional signal taps and antennas can quickly and
easily 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 the
layout should change (e.g. modernization retrofits or process modifications).
