What is 5G?
5G is the fifth generation of wireless technology, succeeding 4G LTE. It promises significantly faster speeds, lower latency, and greater capacity compared to its predecessors. While 4G revolutionized mobile internet, 5G is designed to support a fully connected world, enabling everything from smart cities to advanced industrial automation.
Key Features of 5G
- Faster Speeds:
5G offers download speeds of up to 10 Gbps, which is 100 times faster than 4G. This means downloading a full-length HD movie in seconds. - Lower Latency:
Latency, or the time it takes for data to travel between devices, is reduced to 1 millisecond with 5G. This is critical for real-time applications like gaming, remote surgery, and autonomous driving. - Greater Capacity:
5G can support up to 1 million devices per square kilometer, making it ideal for densely populated areas and IoT ecosystems. - Network Slicing:
This feature allows network operators to create multiple virtual networks within a single physical 5G network, tailoring each slice to specific applications or users.
