13.2 Cellular antenna
The antenna shall not be installed inside metal cases.
The antenna is supplied separately. Use only an approved antenna.
We provide a complete catalog of cellular antennas.
13.3 Coaxial cable
If necessary, the antenna can be connected to the IPL through a coaxial cable.
The signal attenuation in a usual coaxial cable is 0.2 to 0.4 dB / m, that is to say 2 to 4 dB for a 10 meters
long cable.
If a coaxial cable must be used to connect the antenna to the IPL, the attenuation in the cable has to be
taken into account to calculate the effective RF signal received by the IPL.
Refer to our cables and antennas catalogue.
13.4 Cellular service subscription
The IPL is designed to connect to the LTE-UMTS-GPRS data transmission service like the one used by the
tablets.
The subscription should also provide the SMS service if SMS alarms are required.
A telephone service subscription is not needed.
One will take care to subscribe to a service authorizing the right volume of data per month (MB/month) and
to check the price of the MB exceeding the limit of the subscription plan, if it exists.
The subscription must be preferably signed in the country where the machine is supposed to be installed to
avoid roaming costs.
