Checking the Signal Field Strength of the Mobile
Phone Network
You can check the signal field strength at the location of the INSYS GSM 4.3. The
signal field strength has an essential effect on the data transmission speed. If the
signal field strength is too low, the transmission speed may drop too much or the
connection may be terminated completely. The signal field strength is visible for
you in three ways: via the flashing frequency of the signal LED, via HSComm, or via
an AT command.
