2. How Does 5G Differ From 4G?

While both 5G and 4G are designed to deliver mobile connectivity, 5G is a significant upgrade in terms of speed, capacity, and overall performance. Below, we compare some of the key technical differences between 5G and 4G.

Speed and Data Transfer Rates

• 4G Speeds: 4G networks, which were first introduced in 2009, typically offer download speeds ranging from 20 Mbps to 100 Mbps, with peaks that can reach 1 Gbps under ideal conditions. This speed is sufficient for tasks like streaming HD videos, browsing the web, and video conferencing.
• 5G Speeds: 5G, however, can deliver download speeds ranging from 100 Mbps to over 10 Gbps, with some theoretical speeds potentially even higher. This allows for ultra-high-definition (UHD) video streaming, rapid file downloads, and other high-bandwidth applications.

The speed difference between 4G and 5G means that 5G can handle more data at once, enabling innovations like real-time augmented reality (AR), virtual reality (VR), and large-scale IoT deployments.

Latency

• 4G Latency: 4G networks typically have a latency of 30-50 milliseconds, which is good for most applications but can be noticeable in more time-sensitive tasks, such as gaming or autonomous vehicle communication.
• 5G Latency: One of the standout features of 5G is its ultra-low latency, aiming for 1 millisecond or less. This reduction in latency opens up new possibilities for applications where real-time data transfer is critical, such as remote surgery, autonomous driving, and industrial automation.

Network Capacity

• 4G Capacity: 4G networks are capable of handling a limited number of connected devices and are often stretched to their limits in densely populated areas or during peak usage times.
• 5G Capacity: 5G networks, on the other hand, are designed to handle millions of connected devices in a square kilometer. This is crucial for the continued expansion of the Internet of Things (IoT), where everything from smart refrigerators to industrial machinery needs to be connected.

5G’s increased capacity will enable more connected devices to operate simultaneously without causing network congestion, thus supporting the growth of smart cities and other interconnected environments.

Frequency Bands

• 4G: 4G networks operate on lower frequency bands (below 6 GHz), which provide adequate coverage and data rates over medium distances. However, 4G networks are limited in terms of handling large amounts of data due to the frequency limitations.
• 5G: 5G utilizes both lower frequencies (like 4G) and higher frequencies, specifically the millimeter-wave spectrum (above 24 GHz). These higher frequencies allow for faster data transfer but have a shorter range and are more easily blocked by physical obstructions. To mitigate this, 5G networks will rely on a denser array of small cell towers, which are placed closer together to ensure reliable coverage.

Energy Efficiency

• 4G: 4G networks are relatively energy-efficient for the most part, but as more devices and users connect to the network, energy consumption can increase.
• 5G: 5G networks are designed to be more energy-efficient, even as they support a larger number of connected devices. Through advanced network management technologies, 5G can reduce power consumption while maintaining high performance.
