- Frequency Bands:
- Sub-1 GHz Bands (Low-Band): These frequencies offer better coverage and penetration but have lower data transfer rates. In Europe, the 700 MHz band is one such example.
- 1-6 GHz Bands (Mid-Band): This is considered the "sweet spot" for 5G as it balances coverage and capacity. Frequencies in the 3.4-3.8 GHz range, known as the C-Band, are commonly used in Europe for 5G.
- 24-100 GHz (High-Band or Millimeter Wave): These bands offer very high data rates but have limited coverage. In Europe, some countries might allocate frequencies in the 26 GHz range for 5G.
- Radio Access Network (RAN):
- 5G uses a combination of macro cells, small cells, and Massive MIMO (Multiple Input Multiple Output) antennas to provide coverage and capacity. Massive MIMO involves using a large number of antennas to increase data throughput and improve network efficiency.
- Modulation and Coding:
- 5G uses advanced modulation and coding schemes to transmit data efficiently. Higher-order modulation (e.g., 256-QAM) allows more bits to be transmitted per symbol, increasing data rates.
- Core Network:
- The 5G core network is designed to be more flexible and scalable than previous generations. It introduces a service-based architecture (SBA) that decouples network functions, allowing for easier customization and deployment of new services.
- Network Slicing:
- 5G supports network slicing, allowing the creation of multiple virtual networks on a shared physical infrastructure. This enables the customization of networks for specific use cases, such as enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), and ultra-reliable low-latency communications (URLLC).
- Latency Reduction:
- 5G aims to reduce latency significantly compared to previous generations. This is crucial for applications like augmented reality, virtual reality, and real-time communication. Ultra-reliable low-latency communication (URLLC) is a key feature for achieving low-latency performance.
- Beamforming and Beam Management:
- 5G systems use beamforming techniques to focus signals in specific directions, optimizing coverage and capacity. This is particularly important in higher frequency bands where signals are more susceptible to obstacles.
- Security Enhancements:
- 5G introduces improvements in security, including stronger encryption algorithms and enhanced authentication mechanisms.
- Spectrum Sharing:
- Dynamic spectrum sharing allows 5G networks to coexist with 4G networks in the same frequency band, facilitating a smooth transition.
