## 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.
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
Accordingly, the following parameters must be configured in the RUs section of the gNB configuration file:
-`if_freq`
-`if_offset`
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 the standardized 3GPP NR bands.
### OAIUE configuration
To configure IF frequencies on the UE side, provide the following command-line
options:
-`if_freq`: DL frequency in Hz
-`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.
### Run OAI with custom DL/UL arbitrary frequencies
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.
