INTRODUCTION – WHYAI IS IMPORTANT
FOR 6G
• 6G wireless networks are expected to deliver terabit-per-second (Tbps) data
rates, ultra-low latency (<1 ms), and massive connectivity for IoT devices,
smart cities, and autonomous systems (Letaief et al., 2019; Saad et al.,
2020).
• However, the high complexity of future networks, including dense
deployments and mmWave/THz communication, makes traditional network
management approaches insufficient (Zhang et al., 2019).
• Therefore, Artificial Intelligence (AI) is essential to enable real-time
decision-making and automation, allowing 6G networks to become self-
optimizing and self-healing (Saad et al., 2020).

OVERVIEW OF AI& MACHINE LEARNING IN
NETWORKS
Artificial Intelligence (AI) enables
machines to perform tasks that usually
require human intelligence, such as
learning and decision-making.
Machine Learning (ML), a branch of AI,
allows systems to improve performance
from data without explicit programming. In
wireless networks, ML analyzes large
volumes of data from traffic, signal
strength, and mobility patterns to predict
conditions, optimize performance, and
enhance service delivery (Letaief et al.,
2019; Zhang et al., 2019).

CHALLENGES AND LIMITATIONSOF AI IN 6G
Data Privacy and Security Issues: Collection and processing of large amounts of user

High Computation Cost: Advanced AI models, especially deep learning algorithms,
require significant computational resources, which can be costly and difficult to
deploy on edge devices.
Need for Large Datasets: AI models perform best with extensive and diverse datasets,
but gathering and labeling such data in 6G networks is challenging.
AI Model Risks
Deployment Challenges in Real-Time Systems
Lack of Standardized AI Frameworks for 6G: There is currently no unified framework
or standard for AI integration across different 6G network layers, leading to
interoperability and consistency issues.
