5G NR (New Radio)
5G New Radio (NR) is the global standard for a unified, more capable 5G wireless air interface. It has been developed by 3GPP to meet the growing demands of mobile broadband and to enable new use cases.
Key Features of 5G NR
- Enhanced Mobile Broadband (eMBB)
- Ultra-Reliable Low-Latency Communications (URLLC)
- Massive Machine-Type Communications (mMTC)
- Flexible numerology and frame structure
- Advanced channel coding schemes
- Massive MIMO and beamforming
- Support for mmWave frequencies
5G NR Improvements
| Aspect | Improvement |
|---|---|
| Peak data rate | Up to 20 Gbps |
| Latency | As low as 1 ms |
| Connection density | 1 million devices per km² |
| Spectrum efficiency | 3x improvement over 4G |
5G NR Architecture
The 5G NR architecture consists of the following key components:
- gNB (Next Generation NodeB): The 5G base station
- 5G Core Network: Evolved packet core for 5G
- UE (User Equipment): 5G-capable devices
- NG-RAN (Next Generation Radio Access Network): The radio access part of 5G
5G NR Frequency Bands
5G NR operates in two frequency ranges:
- FR1 (410 MHz - 7125 MHz): Sub-6 GHz bands
- FR2 (24.25 GHz - 52.6 GHz): mmWave bands
5G NR and Network Slicing
Network slicing is a key feature of 5G NR, allowing operators to create multiple virtual networks on a shared physical infrastructure. This enables customized network capabilities for different use cases and services.
