EP06-E current signal at command

Hi Guys! I have a question about at commands for the EP06-E modem. I need to get the exact fundamental frequency for both downlink and uplink. I didn’t find this command in the official manual. But having connected the modem to the keenetic device, I saw the current frequency displayed on downlink and uplink. Please help me find the required at command.

No such AT command.
the keenetic device could show the downlink and uplink speed, and it is probably counting the rates on the network interface in the Linux kernel.
