8.0 INSTALLATION
8.1 ENGINEERING CONSIDERATION
a. SITE SELECTION
Site selection affects the overall performance of the system hence it
requires prime consideration. The system comprises of a unit, which
houses all the modules. The unit is installed at the indoor site and the
Donor antenna can have directivity to the BTS from where the signals are
proposed to be intercepted.
Once the expected coverage area is determined and a site installation
plan is established, a pre-installation checklist should be considered and
reviewed for the following items:
1. Identify the Service Provider’s base station location and measure the
available signal strength at the exterior of the installation location.
2. Identify the installation location for the DONOR antenna, and review
the antenna manufacturer’s installation procedures for additional
considerations. Ensure that the DONOR antenna has proper
directivity to the service provider’s base station. If the directivity is
obstructed, determine the azimuth position by using a magnetic
compass for approximate alignment of donor antenna with base
station antenna.
Following points need consideration:
•
The DONOR antenna mounted should have direct line of
sight with the donor site (BTS).
•
Likewise the set of SERVER antennas should have proper
directivity to the areas where coverage is desired to
maximize the signal strength.
•
Availability of AC mains for energizing the system.
•
Shortest route without sharp bends for laying RF cable to the
DONOR antenna.
•
Shortest route without sharp bends for laying RF cable to
SERVER antenna.
•
Identify the spot for installing the repeater unit, which is away
from other heat generating appliances or equipment. There
should not be any direct exposure to direct sunlight or
atmosphere consisting of chemical fumes.
•
The structural mounting surface is flat.
