What is 5G ?
Everyone knows 5G, but doesn’t know what is exactly 5G bring and how it impacts our lives. 5G is the 5th generation mobile network. It’s the worldwide wireless standard after 1G, 2G, 3G, and 4G networks and it is designed to increase speed, reduce latency, and improve flexibility of wireless services.

How Fast is 5G ?
The 5G technology peak rate theoretical hits 20 Gbps, while the peak speed of 4G is only 1 Gbps. The 4G and LTE were focused on ensuring connectivity, but the 5G is stroking to next level to bring the advanced connection experience from the cloud to clients.
Now we know that 5G brings us a higher data speed. But the most important benefit that 5G brings is the reduction of network latency, what is so called “low latency”.

What is low latency and why we need it ?
Latency is the time it takes for data to pass from one point on a network to another, you can image that the latency is the delay time between a video captured and displayed on a viewer’s device. So, the latency builds up at every step of the streaming workflow.
The low latency of 5G can be exploited to achieve lots of challenges such as: mission-critical communication and enormous IoT.
Mission-Critical Communication and Service:
5G can boost the fourth industrial and AI (Artificial Intelligent) industry. 5G enables new services and communications to evolve industries with ultra-reliable, available, low-latency links like remote control of critical infrastructures, vehicles, medical, machines and facilities procedures.
Enormous IoT:
5G’s seamless connectivity plays the crucial role to manage enormous number of IoT today. The embedded sensors inside the IoTs receive and send huge data between end and cloud through the 5G to scale down the data rates, low latency and mobility providing extremely lean and low-cost connectivity solutions.
5G also helps to improve much more possibility to support use cases that require very high reliability and extremely low latency. Examples of these use cases include industrial automation, intelligent transportation, smart electricity grid, entertainment support, autonomous vehicles and remote diagnosis and surgery.
