## Description

srsRAN_4G is a full-stack software-defined radio suite that implements the 4G LTE protocol. It provides a modular cellular network stack capable of deploying base stations, core network components, and user equipment simulators.

The project differentiates itself through a hardware-agnostic approach to radio drivers, allowing the software to interface with various software-defined radio front-ends. It implements the entire communication chain in software, from the physical layer to the network core.

The system covers several functional domains, including baseband signal processing, subscriber authentication, and data session routing. It supports the deployment of wireless access points and the simulation of mobile device behavior to test network connectivity.
