3.10.5.4 Common Problems
Problem 1
When enabling the remote access for the OMU, 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 +CSQ command from a modem’s manual.
