# Porting the Cellular Interface library
<a name="freertos-porting-cellular"></a>

FreeRTOS supports the AT commands of a TCP offloaded cellular abstraction layer. For more information, see the [Cellular Interface Library](https://freertos.org/cellular/index.html) and [Porting the Cellular Interface Library](https://freertos.org/cellular-porting-guide.html) on freertos.org.

## Prerequisites

There is no direct dependency for the Cellular Interface library. However, in the FreeRTOS network stack, Ethernet, Wi-Fi and cellular cannot co-exist, so developers must choose one of them to integrate with the [Porting the Network Transport Interface](afr-porting-network-transport-interface.md).

**Note**  
If the cellular module is able to support TLS offload, or does not support AT commands, developers can implement their own cellular abstraction to integrate with the [Porting the Network Transport Interface](afr-porting-network-transport-interface.md).
