Session 02/08 : 5G Flexible Numerology Explained : Dynamic Subcarrier Spacing SCS in 5G wireless

2024-09-26 3

In this video, discover how 5G's Flexible Numerology revolutionizes wireless communication, enabling faster speeds and more efficient connections. Unlike LTE, which uses a fixed 15kHz subcarrier spacing, 5G offers variable subcarrier spacing from 15kHz to 240kHz, adapting to different environments and use cases. Learn why flexible numerology is critical for:

* Lower latency: Smaller slot durations allow faster data transmission.
* Better coverage: Tailored subcarrier spacing for both outdoor macrocells and indoor deployments.
* High-speed connections: Higher subcarrier spacing improves performance in millimeter-wave bands.
* Adaptation to different environments: From urban centres to rural areas, 5G adjusts to various cell sizes and frequency bands.
* Enhanced network efficiency: Flexible numerology optimizes data flow, ensuring smoother connectivity even in high-demand areas.

You’ll also learn:
* Key differences between LTE and NR frame structures
* Why different subcarrier spacing is necessary for 5G networks
* The significance of Delay Spread and Coherence Time in 5G
* How flexible numerology enhances data transmission for faster, more reliable connections
* Real-world applications, from macrocells using 15kHz subcarrier spacing to millimeter-wave bands with 120kHz spacing


We’ll explain essential concepts like delay spread and coherence time, and how they influence symbol duration, making 5G adaptable to large cell sizes and fast-moving users. With flexible numerology, 5G becomes more efficient, versatile, and capable of meeting the needs of the future.

Watch to see how this critical feature powers the next generation of wireless networks!
