FortiWiFi devices with built-in 5G modems allow for monitoring the modem status and radio connection using CLI commands.
The following command is used to view general modem information:
FortiWiFi-LAB # diagnose sys 5g-modem modem-details
--------------------
Modem information details:
--------------------
Vendor: Sierra Wireless
Model: EM9200
Serial Number: A1087395012384
IMEI: 351982704661092
Firmware Version: SWI9X60C_03.12.04.00
Carrier Profile: T-Mobile
Carrier Profile Rev: 1140
Hardware Revision: 1.2
Modem Temperature: 37 °C
Operating Mode: ACTIVE
Supported Network: LTE|5G
Signal Strength: Good
--------------------
The operating mode should be 'ACTIVE', not low power, and the supported network shows that the modem supports 5G.
The following command displays live radio signal and band information:
FortiWiFi-LAB # diagnose test application nr5gd 15
temperature = 37
modem_state = 4
network_mode = NR5G_SA
registration_status = REGISTERED
packet_service_state = CONNECTED
radio_info.band = n77
radio_info.bandwidth = 80 MHz
radio_info.rx_channel = 631248
radio_info.tx_channel = 631248
radio_info.rssi = -73
radio_info.rsrp = -85
radio_info.rsrq = -9
radio_info.snr = 182
radio_info.cell_id = 315
The above command describes the network mode showing 'NR5G_SA', which indicates the modem is actively using a 5G connection. The 'radio_info.band' shows the bands starting with n (e.g., n77) indicate 5G NR frequency. The 'packet_service_state' confirms the active data session on 5G.
