Equipment for GSM/PCS/UMTS cellular phones and TETRA/TETRAPOL
Install the transmitting part in a flat, dry area, separate from the electronic components of the vehicle, away from humidity and
vibrations. If the transmission is impulsive it must be at a distance of at least 1 meter away from other devices.
●
The ROS value (Stationary Wave Ratio) must be as close as possible to the unit (the recommended value is 1.5), while the
maximum acceptable value must never be greater than 2.
●
The ANTENNA GAIN values must be as high as possible and guarantee a sufficient level of spatial uniformity, characterised
by deviations in relation to the average value to the order of 1.5 dB in the 380-460 MHz band and 870-960 MHz and 2 dB in
the 1710-2000 MHz band.
●
The IRRADIATED FIELD in cab value must be as low as possible , and however < 1V/m.
In any case, limits set by the applicable European Directive must never be exceeded.
An optimum position for the antenna would be the front of the cab roof, at a distance of not less than 30 cm from other antennas.
GPS reception and satellite navigation equipment
Install the transmitting part in a flat, dry area, separate from the electronic components of the vehicle, away from humidity and
vibrations. If the transmission is impulsive it must be at a distance of at least 1 meter away from other devices.
The GPS antenna must be installed so as to have the maximum visibility possible of the sky.
In fact, as the signals received from the satellite are at very low power (approximately 136 dBm), almost any obstacle can influence
the quality and performance of the receiver.
The following should therefore be guaranteed:
●
an absolute minimum angle of vision of the sky of 90
°
;
●
a distance no less than 30 cm from any other antenna;
●
a horizontal position and never underneath any metal which makes up part of the cab structure.
Moreover:
●
the ROS value (Stationary Wave Ratio) must be as close as possible to the unit (the recommended value is 1.5), while the
maximum must never be greater than 2 in the GPS frequency range (1575.42
±
1.023 MHz).
●
the ANTENNA GAIN values must be as high as possible and guarantee a sufficient level of spatial uniformity, characterised by
deviations in relation to the average value to the order of 1.5 dB in the 1575.42
±
1.023 MHz band.
Additional equipment
The vehicle system is set up to supply the necessary power to the equipment provided, for each of which, as part of their function,
the specific protection is assured as well as the correct dimensioning of cables.
The installation of additional equipment must include suitable protections and should not overload the vehicle system.
The connection of the added users to ground must be made with an adequately sectioned cable, as short as possible and made to
allow for any movements of the added equipment with respect to the chassis of the vehicle.
The connection of the added users to ground must be made with an adequately sectioned cable, as short as possible and made to
allow for any movements of the added equipment with respect to the chassis of the vehicle. Having the need for higher capacity
batteries, due to added loads, it is appropriate to request the optional with increased batteries and alternators.
In any case, when increasing battery capacity, it is advisable not to exceed 20-30% of the maximum values provided as optional by
IVECO, so as not to damage some of the components (e.g. starter motor). When higher capacities are necessary, use additional
batteries, making the necessary provisions for recharging as indicated below.
