## IF setup with OAI
The `if_freq` and `if_freq_off` options can be used to set (via command line) custom downlink and uplink FR1 arbitrary frequencies for the IF equipment both.
OAI is also compatible with Intermediate Frequency (IF) equipment. This allows to use RF front-end that with arbitrary frequencies bands that do not comply with the standardised 3GPP NR bands.
In the same way, the following parameters must be configured in the RUs section of the gNB configuration file:
To configure the IF frequencies it is necessary to use two command-line options at UE side:
- `if_freq`, downlink frequency in Hz
- `if_freq_off`, uplink frequency offset in Hz
`if_freq`
`if_offset`
The values must be given in Hz.
Accordingly, the following parameters must be configured in the RUs section of the gNB configuration file:
- `if_freq`
- `if_offset`
