The demand for more advanced wireless systems is growing every day. As technology progresses, the need for faster, more reliable networks becomes critical. With 5G and the upcoming 6G, the expectations for wireless connectivity have risen sharply. These next-generation networks require highly skilled engineers who can build systems capable of supporting the increasing number of devices, users, and data. To meet these growing demands, wireless engineers are turning to AI, or artificial intelligence, to build smarter, more efficient networks. So, now let us see Why Do Wireless Engineers Need AI to Build the Networks of Tomorrow along with Smart LTE RF drive test tools in telecom & RF drive test software in telecom and Smart 5g tester, 5G test equipment, 5g network tester tools in detail.
The Challenges of Building Next-Generation Networks
In today’s world, wireless systems, such as base stations, cellular phones, and Wi-Fi modems, face new challenges that weren’t as prevalent before. With an explosion of data usage and the increasing complexity of devices, engineers must create systems that not only meet the current demands but are also adaptable to future needs. More capacity, broader coverage, and the ability to handle a growing number of users are just a few of the factors pushing the limits of traditional wireless networks. The solution? AI-native technologies.
AI-native systems are designed to continuously learn and adapt in real time. These systems can make decisions on the fly, optimizing themselves for better performance. When engineers design wireless systems for future technologies like 5G, 5G Advanced, and 6G, they need to incorporate AI because these systems are too complex for traditional methods to handle. AI allows them to model and simulate network behaviours based on real-world data, learning and evolving as conditions change.
AI-Native Systems: A New Era of Wireless Design
So, what exactly does it mean for a wireless system to be AI-native? Essentially, it means that AI is integrated directly into the core of the system. These AI algorithms are used to improve wireless network coverage, boost capacity, and enhance reliability. Unlike traditional systems, which rely on rigid, predefined models, AI-native systems are flexible and adaptable. They learn from their environment and adjust their behavior to improve performance. This makes them far more scalable and efficient, reducing the need for time-consuming and expensive manual adjustments.
Traditional wireless networks are based on predefined models that engineers have to tune manually. However, these systems can’t keep up with the ever-changing demands of modern communication. AI-native systems, on the other hand, adjust themselves continuously, offering greater flexibility and performance. This is why they’re considered essential for the future of wireless networks.
Shifting from Traditional to AI-Native Design
The transition from traditional wireless systems to AI-native systems is not simple. It requires wireless engineers to expand their skills in ways that were not necessary before. For example, while signal processing has always been a key part of wireless system design, the introduction of 5G and 6G demands much more advanced applications of this technology. Engineers must now integrate machine learning techniques like pattern recognition, anomaly detection, and predictive analytics into their designs. These skills are necessary to ensure that wireless networks can manage the complexities of machine-to-machine communication, handle real-time data processing, and incorporate sensors and actuators into the systems.
The new AI-native systems require engineers to adapt and incorporate these techniques into their workflows. A typical AI-native design process follows a few clear steps:
- Data Collection: Gathering real-world data, either through over-the-air signals, digital twins (virtual representations of the system), or synthetic data, is the first step. The data needs to be comprehensive to train AI models effectively.
- Model Training and Testing: Once data is collected, it is used to train a model that represents the behavior of the wireless system. Engineers apply machine learning algorithms to optimize the model’s performance under various conditions.
- Model Integration: After the model is trained and tested, it needs to be integrated into the wireless system. This requires testing the AI algorithms in real-world scenarios to ensure the system works efficiently.
Collecting and Generating Data for AI Models
For AI-native systems to work effectively, they need a lot of data to train on. Engineers can collect this data in several ways. The most reliable method is to gather real-world over-the-air (OTA) signals using hardware. This allows engineers to capture data directly from wireless networks and use it to train AI models. However, collecting this data can be challenging, especially when it comes to ensuring the data is accurate and comprehensive.
Another option is to use digital twins, which are virtual models of the wireless systems. Digital twins can simulate real-world conditions and provide data that mimics the behavior of actual systems. While this can make data collection easier, digital twins still require a lot of attention to detail to ensure that they accurately represent real-world conditions.
In situations where real-world or digital twin data isn’t available, engineers turn to synthetic data. This is data that is created using statistical models and algorithms. While not as reliable as real-world data, synthetic data can still provide useful information for training AI models. Engineers need to ensure that synthetic data closely mirrors real-world scenarios so that the AI model can make accurate predictions.
Training and Testing AI Models
Once data is gathered, engineers use it to train AI models. This involves setting parameters that define the model’s behavior and applying machine learning techniques to optimize them. Engineers must ensure that the training process is both efficient and fast so that the model can perform well in real-world systems.
After the model is trained, it undergoes testing and validation. This step ensures that the AI system works correctly in various real-world scenarios and that it performs reliably under different conditions. Engineers test the model by running it in a simulated environment and comparing its predictions with actual outcomes. This helps identify any discrepancies and ensures the system will work as intended when deployed.
Implementing AI-Native Models into Real-World Systems
Once the AI model is validated, it must be implemented into the wireless system. This involves scaling the model to ensure it can handle real-time conditions. Engineers assess the system’s processing power and memory requirements to ensure the AI model can operate efficiently. Once this is done, they deploy the model and integrate it into the wireless system.
This step is crucial because AI-native systems must be efficient in terms of power usage, memory consumption, and computational complexity. If the system isn’t efficient, it won’t be able to respond to changing conditions in real time. Therefore, engineers need to ensure that the system is optimized for performance and reliability.
Overcoming Challenges in AI-Native Design
While AI-native systems offer numerous benefits, there are challenges to overcome. One of the main challenges is balancing performance metrics. For example, improving one aspect of a wireless system, such as capacity, might reduce performance in another area, such as energy efficiency. Engineers must carefully balance these competing objectives to ensure the system performs optimally.
AI-native systems also need to operate in dynamic environments, which can be unpredictable. Factors like network congestion, signal interference, and varying user demands can impact performance. AI models must be able to adapt to these changing conditions and maintain consistent performance.
Additionally, because AI models depend heavily on data, the changing nature of 5G and 6G networks makes it difficult for AI to generalize across all conditions. This requires engineers to use advanced techniques like multi-objective optimization to ensure that the system can balance various performance metrics while accounting for real-world data variability.
Conclusion: The Future of Wireless Networks
The future of wireless networks relies heavily on the integration of AI-native technologies. As 5G and 6G networks continue to evolve, wireless engineers will need to adapt and embrace AI to build systems that can handle the increasing demands for capacity, coverage, and reliability. By using AI, engineers can create smarter, more efficient networks that are capable of continuously learning and adapting to changing conditions. This is the future of wireless design, and it’s already happening today.
