Two-way systems for GSM/PCS/UMTS mobile phones
Cellular telephone systems must be installed using the power system provided in the vehicle. Connect to terminal 30 via a supple-
mentary fuse.
The devices must be legally type-approved and fixed (not portable). Install the transmitting part in a flat, dry area separate from the
electronic components of the vehicle, away from humidity and vibrations.
•
The SWR must be as close as possible to one. The recommended value is 1.5, while the maximum acceptable value must not
in any case be greater than 2.
•
The
AERIAL GAIN
values must be as high as possible and ensure sufficient spatial uniformity, normally with deviations from the
average value in the order of 1.5dB in the 870-960 MHz band and 2 dB in the 1710-1880MHz band.
•
The
RADIATED CAB FIELD
value must be as low as possible. We suggest < 1 V/m as a quality target. In any case, the value
must not exceed limits imposed by current European guidelines.
•
For this reason
, the aerial must always be placed on the outside of the vehicle cab, if possible on a broad metal base fitted as
upright as possible with the connection lead facing downwards, observing the Manufacturer’s installation instructions and warn-
ings.
The ideal location of the antenna is on the front of the cab roof at a distance no less than 30 cm from other antennas.
