Report 3 - Wireless Technologies, 5G

Q1: What does 5G stand for and what generation is it?

5G stands for "fifth generation" wireless technology, succeeding 1G through 4G.

Q2: What are the key improvements of 5G over previous generations?

Enhanced speeds, lower latency, broader bandwidth, and support for more devices simultaneously.

Q3: What technologies does 5G enable in Industry 4.0?

Internet of Things (IoT), cloud computing, artificial intelligence, and machine learning.

Q4: What are the three spectrum bands used in 5G?

Low, mid, and high frequency bands.

Q5: Why does 5G require more nodes in urban infrastructure?

High-frequency signals struggle with distance and obstacles, so nodes on buildings and streetlights strengthen connectivity.

Q6: What is network slicing in 5G?

It divides the network into specialized segments tailored to different user needs for efficient management.

Q7: How does 5G improve latency and error rates?

It uses a more powerful Modulating and Coding Scheme (MCS), reducing delay and transmission errors.

Q8: How does 5G benefit individual users?

Faster internet speeds, lower latency, broader bandwidth, and fewer transmission errors.

Q9: What does broader bandwidth mean for users?

More devices can connect simultaneously without performance degradation.

Q10: How does lower latency improve user experience?

Data travels faster between devices, improving responsiveness for apps and streaming.

Q11: How does 5G benefit the healthcare industry?

Enables high-definition live streaming for surgeries and fast access to patient data.

Q12: How is 5G used in autonomous transportation?

It supports faster communication between vehicles and infrastructure, improving safety and efficiency.

Q13: What role does 5G play in mining operations?

Monitors worker vitals and toxic gases; enables autonomous drilling and remote-controlled vehicles.

Q14: How does 5G compare to Wi-Fi in underground mining tests?

Wi-Fi had slightly lower latency, but 5G had 20x lower packet loss, making it more reliable.
