  1. Frequency Bands:
    • 5G operates across a wide range of frequency bands, including sub-1 GHz, 1-6 GHz, and above 24 GHz (millimeter-wave bands). This enables a variety of use cases, from broad coverage in lower frequencies to high data rates in millimeter-wave bands.
  2. New Radio (NR) Technology:
    • 5G NR uses a new air interface, different from its predecessors (3G, 4G). It supports a flexible numerology, allowing for different subcarrier spacings, which is essential for accommodating diverse services with varying latency and throughput requirements.
  3. Massive MIMO (Multiple Input, Multiple Output):
    • Massive MIMO involves deploying a large number of antennas at both the base station (gNB - gNodeB) and the user equipment (UE). This technology enables improved spectral efficiency and increased capacity by spatially multiplexing multiple users.
  4. Beamforming:
    • Beamforming is a key technique in 5G that allows the transmission and reception of radio waves in specific directions. By focusing energy in the direction of the user equipment, beamforming improves signal quality and coverage.
  5. Full Duplex Communication:
    • 5G supports full-duplex communication, allowing data transmission and reception to occur simultaneously on the same frequency. This is achieved through advanced antenna and radio frequency (RF) technologies.
  6. Dynamic Spectrum Sharing (DSS):
    • DSS enables the coexistence of 4G LTE and 5G NR services on the same frequency band, allowing for a smoother transition from 4G to 5G without requiring separate spectrum allocations.
  7. Network Slicing:
    • 5G introduces the concept of network slicing, which enables the creation of multiple virtual networks with different characteristics (e.g., latency, bandwidth) on a shared physical infrastructure. This is crucial for supporting diverse use cases with varying requirements.
  8. Edge Computing:
    • 5G networks leverage edge computing to reduce latency and bring computation closer to the end-users. This is essential for applications that require real-time processing, such as augmented reality (AR) and virtual reality (VR).
  9. Advanced Modulation and Coding:
    • 5G uses advanced modulation and coding schemes, such as 256-QAM (Quadrature Amplitude Modulation), to increase data rates. However, these schemes are more susceptible to channel impairments, so effective error correction mechanisms are also employed.
  10. Control and User Plane Separation (CUPS):
    • 5G introduces the separation of the control plane and user plane, allowing for more flexibility and scalability in network architecture. This separation enables dynamic resource allocation and efficient network management.

These technical features collectively contribute to the enhanced performance, lower latency, and increased capacity of 5G Advanced, making it suitable for a wide range of applications, including enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), and ultra-reliable low-latency communication (URLLC).
