## IF setup with OAI
The -C and --CO flags can be used together at UE side to set custom downlink and uplink FR1 arbitrary frequencies for the IF equipment.
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 order to run this setup, the following flags are needed at the UE side:
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
`-C`
`--CO`
and the following parameters must be configured in the RUs section of the gNB configuration file:
`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`
