Descriptions and calculations shall show how the equipment will operate as
a system to meet the specified performance requirements. Package shall
include calculations and/or test results which indicate adequate signal
strength to ensure reliable radio switch operation throughout areas where
radio switches are in service.
1.4.1.4
RF Area Coverage Report
The Group I data package shall include an area coverage report
incorporating a topographical map with coverage indicated. The following
shall be shown on the map:
a.
Location of the transmitter and antenna.
b.
Location of the most distant radio switch in each compass quadrant
from the transmitting antenna.
c.
Radials (straight line segments indicating direction, distance and
difference in elevation) from the transmitting antenna to the
radio switches described in b. above.
d.
Location along each radial of any obstacle to line of sight
propagation.
e.
Radiation pattern of the transmitted signal.
f.
Attenuation (dB) between the transmitting antenna and the radio
switches described in b. above. The system loss shall take into
account the effect of terrain variables such as distance, antenna
height, obstructions, and absorption losses.
g.
System gain for each radio switch location described in b. above.
The system gain shall take into account the attenuation between
the Central Station or repeater and the antennas, the gain of each
antenna, and the transmission line losses.
h.
Power output of the transmitter.
i.
Calculated receiver input signal voltages and signal-to-noise
(S/N) ratios for radio switches described in b. above.
1.4.1.5
Manufacturer's Certifications
Manufacturer's certifications shall be included with the Group I data
package.
1.4.2
Group II Technical Data Package
**************************************************************************
NOTE: Remove Group II when there is no Government
furnished equipment.
**************************************************************************
The Group II technical data package shall include the results of the
testing and calibration of the Government furnished RFCE. Defective or
nonrepairable equipment shall be reported. An estimate of the materials
and costs required to repair or replace defective equipment shall be
provided. Within 10 days after completion of testing and calibration, a
certificate shall be provided that the Government furnished RFCE is in
