5G and Wireless Communication for Beginners - Long Term Evolution (LTE) for 4G

The video tutorial discusses the evolution of LTE and its integration into 5G standards. It covers key aspects of non-standalone 5G networks, focusing on frequency modulation and duplexing techniques like OFDM, time division duplexing (TDD), and frequency division duplexing (FDD). The tutorial explains how these techniques help in efficient use of frequency bands and reduce interference. It concludes with a look at the benefits of LTE's continued relevance in 5G, highlighting cost savings in infrastructure deployment.

What does LTE stand for, and what is its significance in the context of 5G?

• Limited Technology Evolution; it is outdated.

• Long Term Evolution; it is a static technology.

• Limited Time Evolution; it is a temporary solution.

• Long Term Evolution; it evolves to meet new generation needs.

How does OFDM contribute to 5G technology?

• It is a type of frequency modulation only.

• It is a type of multiplexing and modulation technique.

• It is unrelated to 5G technology.

• It is used for signal amplification.

What is the primary purpose of using OFDM in 5G networks?

• To reduce the cost of network infrastructure.

• To enhance the visual quality of video calls.

• To ensure safe separation of signals and prevent interference.

• To increase the speed of data transmission.

What is the main difference between TDD and FDD in 5G networks?

• TDD uses time slots, while FDD uses different frequencies.

• TDD is faster than FDD.

• FDD is more cost-effective than TDD.

• TDD and FDD are the same.

Why is LTE still relevant in the 5G era?

• It is faster than 5G.

• It is the only option for mobile networks.

• It is cheaper to maintain than to overhaul.

• It is no longer relevant.
