8.3.4 Common Problems

Problem 1

When enabling the remote access for the repeater, the modem fails to log in to the network.

Solution

Signal strength from the donor site is too low. The signal strength can be read directly from
the modem. Go in to Direct Modem Access as described earlier. Use the command
AT+CSQ (documented below) to read out the signal strength.
In order to have good signal quality, Axell Wireless recommends that the signal strength
should be better than -95 dBm. If signal strength is lower, try to adjust the antennas to get a
better signal strength from the donor.

Documentation of +C

SQ command from a modem’s manual.

In the example the reply to
AT+CSQ is 0,7 meaning 7*2 dB
above -113 dBm; the modem
detects a signal level of -99
dBm.
