5 OPERATIONAL BASICS

5.1

Operational principals

FM3622 module is designed to acquire records and send them to server. Records contain
GNSS data and I/O information. Module uses GNSS receiver to acquire GNSS data and is powered
with four data acquire methods: time-based, distance-based, angle-based and speed-based
method. Note, that if FM3622 loses connection to GNSS satellites, it continues to make records,
however coordinate in these records remains the same (last known coordinate). Method's
details are described in section 5.13. All data is stored in flash memory and later can be sent via
3G, GPRS or SMS. 3G mode is the most preferred data sending mode. If 3G coverage is not
available the device sends data through GPRS network. FM3622 can also be configured to send
data over GPRS and SMS only. This mode can be used to save bills or in the areas where 3G is not
available. The least preferred data sending mode is SMS, which is mostly used in areas without
GPRS coverage or GPRS usage is too expensive.
