Technical Tip: How to check the stats for the LTE modem
Description
This article describes that most LTE modems have a preset APN in the SIM card.
As a result, the APN does not need to be set in FortiOS configuration.
In cases where the Internet cannot be accessed, consulting the carrier about APN and set the APN in LTE modem configuration is possible using the below command:
config system lte-modem
set status enable
set apn "inet.bell.ca"
end
This article describes how to check the strength and other statistics of the SIM card (LTE/3g).
Scope
FortiGate.
Solution
A few commands to check the lte-modem stats:
- For Signal strength.
diagnose sys lte-modem signal-info
LTE Modem signal information:
WCDMA:
RSSI: -57
ECIO: 12
LTE:
RSSI: -67
RSRQ: -13
RSRP: -98
SNR: 44
- The SNR(signal / thermal noise power) is in scaled integer in 0.1 dB units, so the above output, the SNR is 4.4 dB.
- For the Traffic status.
diagnose sys lte-modem traffic-status
LTE Modem traffic status:
TX packets OK: 8513
RX packets OK: 10842
TX packets error: 0
RX packets error: 0
TX overflows: 0
RX overflows: 0
TX bytes OK: 748973
RX bytes OK: 8770104
TX packets dropped: 0
RX packets dropped: 0
Some other commands:
diagnose sys lte-modem
