Why Do We Need AI in 6G?

With 5G, AI was a supporting tool—primarily used for optimizing network performance. However, the sheer complexity of 6G networks, operating at terahertz frequencies and supporting billions of connected devices, makes manual optimization almost impossible.

Key challenges include:

• Real-Time Decision Making: 6G networks must process and respond to events faster than ever, like rerouting data for autonomous cars or managing virtual environments in the metaverse.

• Dynamic Resource Allocation: Efficiently managing bandwidth, power, and computing resources across billions of devices in diverse environments.

• Self-Healing Networks: Detecting and fixing faults autonomously to maintain ultra-reliable connections.

How 6G Solves This

6G is AI-native, meaning AI and machine learning (ML) are not just tools but integral components of its architecture. Here’s how AI transforms the 6G landscape:

1. AI for Predictive Network Management

• Challenge: Networks today react to events like congestion or failures.

• Solution: AI predicts these issues before they occur, optimizing routes and resources in real time.

2. Edge AI for Ultra-Low Latency

• Challenge: Processing data in centralized clouds introduces delays.

• Solution: AI models run directly on embedded devices, enabling real-time decisionmaking at the edge.

3. AI-Powered Signal Optimization

• Challenge: Managing interference and attenuation at terahertz frequencies.

• Solution: AI dynamically adjusts signal paths and beamforming parameters to ensure reliability.

Use Cases Driving AI-Enabled 6G

1. Autonomous Systems

• AI enables ultra-reliable, low-latency communication for fleets of self-driving cars, drones, and delivery robots.

• Example: Drones in smart agriculture analyzing crop health in real time and coordinating with ground-based machines.

2. Digital Twins in Smart Manufacturing

• Real-time synchronization of physical and virtual worlds for monitoring, simulation, and optimization.

• Example: A factory where every machine’s digital twin predicts failures and optimizes production schedules autonomously.

3. Personalized Healthcare

• AI processes health data from wearable devices, providing real-time insights and alerts.

• Example: Continuous glucose monitoring with predictive AI for diabetics, ensuring timely interventions.

4. Dynamic Metaverse Experiences

• AI adapts environments in real time, ensuring smooth interactions and seamless transitions.

• Example: Real-time adaptation of a virtual concert for millions of users based on their preferences and locations.

Standards and Frameworks to Explore

Embedded engineers can refer to these standards and frameworks to understand how AI integrates with 6G:

• ETSI ENI (Experiential Networked Intelligence): Framework for AI-based network optimization.

• 3GPP Release 20: Focused on embedding AI into 6G architecture.

• ITU-T Y.3172: Architectural framework for AI in future networks.

• OpenAI’s Edge AI Research: Practical models for implementing on-device intelligence.

Why Embedded Engineers Must Focus on AI

In the 6G era, every embedded system will be a smart system. Embedded engineers with expertise in on-device AI, edge intelligence, and real-time processing will drive the evolution of intelligent connectivity.
