GSM/3G connection
Available in HD35APG.../HD35AP3G...
The GSM/3G connection also allows the monitoring of moving systems at a great distance, as for example in the case of the transport of
perishable goods. Simply install the base unit in the moving system (for example inside a truck), in addition to the data loggers, to con-
stantly keep under control the measured parameters from a fixed location. The communication through the GPRS/3G TCP/IP protocol
allows interacting with the base unit, in order to know and change the configuration of the system at any time. SMS messages can be
sent to the base unit, to control the GSM/3G functions of the unit.
Transmitting frequency
All the models (except HD35APD and HD35APG...) are available in three versions, depending on the transmitting frequency band:
- 868 MHz (in compliance with the european normative ETSI EN 300 220);
- 902-928 MHz (in compliance with U.S. FCC part 15 section 247 and I.C. RSS-210 regulations);
- 915.9-929.7 MHz (in compliance with ARIB STD-T108 standard).
The base units HD35APD and HD35APG... are available only with 868 MHz or 902-928 MHz frequency band.
The 902-928 MHz frequency band can be reduced to 915-928 MHz (Australia) or 921.5-928 MHz (New Zealand).
The wireless transmission of the system is extremely robust against radio frequency interference. The system is able to detect any RF
interference in the transmission channel, and to transfer, upon request, the data communication to another channel of the same
transmitting band. The correctness of the transmitted data is ensured by the bidirectional communication between the base unit and
the remote data loggers.
