5G vs 6G: What’s the Difference and What Should You Expect?

5G is an upgraded wireless technology from the current 4G; it is the fifth generation that can provide higher speeds, low latency, and high device connections. 5G networks were launched across the world from the year 2020. This article will cover all about 5G vs 6G.

6G is known as the sixth next-generation wireless communication, which targets to achieve a data rate of 1Tbps and latency of 1 microsecond. The 6G is expected to be in the market during the 2030s.

Wireless communication technologies are on a higher rate of growth than ever before with 5G networks already changing the society’s relationship with technology. 

However, even as 5G’s implementation goes on, there is 6G around the corner in future innovation. What is 6G, what are the principal distinctions between it and 5G, and what expectations can be made regarding such developments?

What is 5G Technology?

Overview of 5G

5G is the abbreviated form of the fifth generation of wireless technology and it is the newest standard in mobile networks succeeding the 4G LTE. It says that the speeds it offers would be much higher than current fixed broadband, with the latency much lower and connectivity for devices even higher. Built for the increasing volume of data, 5G is the solution that allows multiple devices to communicate and helps create innovations from smart cities to self-driving cars to VR.

Key Features of 5G

1. Speed: 5G is theoretically twenty times faster than 4G, in other words, it provides up to 100 times faster speed. Theoretical maximum speeds of up to 10 Gbps can be achieved although this is not very typical for the users thus the range of 100Mbps-1Gbps.
2. Latency: 5G significantly reduces latency, lowering it to just 1 millisecond to enable real-time communication between devices and networks.
3. Capacity: The 5G networks may support approximately 1 million connections per square kilometre for facilitating the networks of high user traffic in areas such as cities.
4. Spectrum: 5G makes use of bands in the high-frequency regime (millimetre wave) to achieve high data rates albeit in very small cells. It also employs the mid- and low-frequency bands to offer wider coverage.

Real-World Applications of 5G

• Smart Homes: 5G will therefore allow the connection of devices in our homes to be controlled by efficient means making it possible to control even the lighting features of buildings and our security systems.
• Autonomous Vehicles: Fast response time and availability of real-time information make 5G crucial when it comes to the functioning of self-driving cars.
