1. 4G (Fourth Generation):

Overview:
4G is the fourth generation of mobile telecommunications technology, succeeding 3G. It is designed to provide faster data transfer rates, more reliable connections, and improved efficiency compared to its predecessors.

Technical Features:

  • Data Rates: 4G networks can provide download speeds of up to 100 Mbps for mobile devices moving at high speeds and up to 1 Gbps for stationary devices.
  • Technology: 4G primarily uses technologies such as LTE (Long-Term Evolution) and WiMAX (though LTE became the dominant standard).
  • Latency: Lower latency compared to 3G, typically around 30 milliseconds or lower.

2. 5G (Fifth Generation):

Overview:
5G is the fifth generation of mobile network technology, succeeding 4G. It aims to provide significantly faster data speeds, lower latency, increased reliability, and support for a massive number of connected devices.

Technical Features:

  • Data Rates: 5G promises peak data rates of up to 20 Gbps, though real-world speeds might be lower, ranging from 100 Mbps to several Gbps.
  • Technology: 5G utilizes advanced technologies such as mmWave (millimeter-wave), Massive MIMO (Multiple Input Multiple Output), and beamforming to achieve high speeds and efficiency.
  • Latency: Target latency is reduced to around 1 millisecond or even lower.

3. NSA (Non-Standalone):

Overview:
NSA (Non-Standalone) refers to the deployment of 5G technology that relies on existing 4G LTE infrastructure for certain network functions. It's a transitional approach to 5G deployment before full-fledged standalone 5G networks are established.

Technical Details:

  • Integration: In NSA mode, the 5G NR (New Radio) radio access component is added to the existing LTE network. This allows for simultaneous operation of 4G and 5G technologies.
  • Control Plane: While the user plane traffic (data transfer) might leverage 5G capabilities, the control plane (management of connections, signaling, etc.) still uses the 4G LTE core network.
  • Evolution Path: NSA is considered a stepping stone to fully realizing the capabilities of 5G. As more infrastructure is developed and deployed, operators can transition to a standalone (SA) 5G network, which will have its core network independent of 4G LTE.

Conclusion:

4G and 5G represent different generations of mobile network technology with varying speeds, latency, and efficiency, NSA is a deployment approach for 5G that initially relies on 4G infrastructure. This method allows operators to roll out 5G more quickly and cost-effectively before moving entirely to standalone 5G networks.
