Documentation Status

[``nrarfcn``](https://github.com/blevic/nrarfcn): a 5G NR-ARFCN calculator, as a Python package.

This is a Python package that calculates the frequency for a given NR-ARFCN, the NR-ARFCN for a given frequency, and related NR band information, according to 3GPP **Rel-17**.

It follows [3GPP TS 38.104](https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=3202) v17.6.0: "_5G; NR; Base Station (BS) radio transmission and reception_".

### Documentation

[``nrarfcn``](https://github.com/blevic/nrarfcn) is documented on: [nrarfcn.rtfd.io](https://nrarfcn.rtfd.io/).

### Installation

```bash
pip install nrarfcn
```

### Usage

```python
>>> import nrarfcn as nr

>>> nr.get_frequency(620000)
3300.0

>>> nr.get_nrarfcn(27500.0)
2070832

>>> nr.get_bands_by_frequency(1850.0)
['n2', 'n3', 'n25']

>>> nr.get_bands_by_nrarfcn(2564083)
['n263']

>>> nr.get_duplex_mode('n71')
'FDD'

>>> nr.get_nrarfcn_range('n25', direction='ul')
(370000, 383000)

>>> nr.get_frequency_range('n100', direction='dl')
(919.4, 925)

>>> nr.get_frequency_by_gscn(2156)
862.85

>>> nr.get_gscn_by_frequency(4405.440)
8475

>>> nr.get_gscn_range('n92')
(3584, 3787)
```
