srsRAN_4G is an open-source 4G/LTE software radio suite developed by SRS (Softwareradiosystems). It provides a complete 4G/LTE stack implementation, including a User Equipment (UE) and an Evolved Node B (eNodeB) implementation, allowing for the creation of 4G/LTE networks and devices.

Pros

• Comprehensive 4G/LTE Implementation: srsRAN_4G offers a complete 4G/LTE stack, including both UE and eNodeB components, enabling the development of full-fledged 4G/LTE networks and devices.
• Open-Source and Free: The project is open-source and available free of charge, allowing for community contributions and customizations.
• Flexibility and Modularity: The software is designed to be modular, allowing users to selectively build and deploy only the components they require.
• Hardware Support: srsRAN_4G supports a wide range of software-defined radio (SDR) hardware, making it versatile for various deployment scenarios.

Cons

• Complexity: The comprehensive nature of the 4G/LTE stack implementation can make the project complex to set up and configure, especially for newcomers.
• Performance Limitations: While the project aims to provide a complete 4G/LTE solution, its performance may not match that of commercial-grade 4G/LTE equipment, especially in terms of throughput and latency.
• Lack of Extensive Documentation: The project's documentation, while available, could be more comprehensive and user-friendly, particularly for those new to 4G/LTE development.
• Limited Commercial Support: As an open-source project, srsRAN_4G may not have the same level of commercial support and maintenance as proprietary 4G/LTE solutions.

Code Examples

Since srsRAN_4G is a comprehensive 4G/LTE software suite, it does not lend itself well to providing concise code examples. The project consists of multiple components, each with its own set of complex configurations and interactions. However, here are a few high-level examples to give you a general idea of the project's capabilities:

1. Initializing the UE Component:

#include <srsran/ue/ue.h>

int main() {
    srsran_ue_t ue;
    srsran_ue_init(&ue, /* parameters */);
    srsran_ue_start_rrc(&ue);
    srsran_ue_start_mac(&ue);
    // Perform UE operations
    srsran_ue_stop(&ue);
    srsran_ue_free(&ue);
    return 0;
}

2. Configuring the eNodeB Component:

#include <srsran/enb/enb.h>

int main() {
    srsran_enb_t enb;
    srsran_enb_init(&enb, /* parameters */);
    srsran_enb_start_rrc(&enb);
    srsran_enb_start_mac(&enb);
    srsran_enb_start_phy(&enb);
    // Perform eNodeB operations
    srsran_enb_stop(&enb);
    srsran_enb_free(&enb);
    return 0;
}

3. Performing a Handover:

#include <srsran/ue/ue.h>
#include <srsran/enb/enb.h>

int main() {
    srsran_ue_t ue;
    srsran_enb_t enb;
    // Initialize and start UE and eNodeB
    srsran_ue_start_rrc(&ue);
    srsran_enb_start_rrc(&enb);
    // Perform handover procedure
    srsran_rrc_ue_handle_ho_command(&ue, /* handover parameters */);
    srsran_rrc_enb_handle_ho_preparation(&enb, /* han
