Welcome to the section on the 5G Radio Access Network (RAN)! In this session, we'll dive into how 5G NR (New Radio) revolutionizes the wireless interface compared to LTE, using technologies like MIMO and Beamforming to handle new use cases and improve performance. We'll break down the basic concepts and how they contribute to 5G's enhanced data rates, coverage, and low-latency services.
Topics Covered:
* 5G NR and its Requirements: Learn how 5G must optimize millimeter-wave spectrum and handle new use cases, leading to the development of NR (New Radio).
* LTE & 5G Coexistence: How 5G NR works in conjunction with LTE to maximize performance.
* Massive MIMO Explained: Understand how MIMO (Multiple Input Multiple Output) technology uses multiple antennas to improve the capacity, throughput, and reliability of the 5G network.
* Beamforming Techniques: Learn how Beamforming focuses signals towards users, improving coverage and efficiency in high-frequency bands like millimetre waves.
* Diversity and Spatial Multiplexing: Discover how MIMO leverages diversity to improve signal-to-noise ratios and uses spatial multiplexing to send multiple data streams for higher throughput.
* Analog, Digital, and Hybrid Beamforming: Get to know the different forms of Beamforming used in 5G and how they improve coverage and performance, particularly in high-frequency millimetre-wave bands.
Key Takeaways:
* Understanding MIMO: Learn the basics of SISO, MISO, and MIMO and how these systems improve signal quality and data capacity.
* Massive MIMO: Discover the benefits of massive MIMO, a key 5G technology that boosts network capacity by using arrays of 16 or more antennas.
* Beamforming: Find out how Beamforming works in both analog and digital forms, and how it's used in 5G NR to maximize signal strength and coverage.
* Millimetre-Wave Challenges: Learn why millimetre-wave bands require special techniques like Beamforming to ensure efficient coverage despite their poor propagation.
