## IF setup with OAI
## IF setup with OAI
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.
OAI is also compatible with Intermediate Frequency (IF) equipment, allowing the
use of RF front-ends operating on arbitrary frequency bands that do not conform
To configure the IF frequencies it is necessary to use two command-line options at UE side:
to the standardized 3GPP NR bands.
-`if_freq`, downlink frequency in Hz
-`if_freq_off`, uplink frequency offset in Hz
### OAIUE configuration
To configure IF frequencies on the UE side, provide the following command-line
Accordingly, the following parameters must be configured in the RUs section of the gNB configuration file:
options:
-`if_freq`
-`if_freq`: DL frequency in Hz
-`if_offset`
-`if_freq_off`: UL frequency offset in Hz
### gNB configuration
On the gNB side, the corresponding parameters must be set in the RUs section of
the configuration file:
-`if_freq`: DL frequency in Hz
-`if_offset`: UL frequency offset in Hz
> Note: When using a libconfig-based configuration file for the gNB, ensure that
> `if_freq` numeric value is suffixed with "L" so it is correctly parsed as
> 64-bit integer.

The following example uses DL frequency 2169.080 MHz and UL frequency offset -400 MHz, with a configuration file for band 66 (FDD) at gNB side.
