5G in a Nutshell

In a nutshell: 5G is the next generation of wireless technology. It has the potential to completely alter many other sectors due to its faster speed, reduced latency, and higher dependability.

5G wireless technology powers the Fourth Industrial Revolution.

5G beats 4G.

How does it work?

Like existing cellular networks, 5G networks divide their coverage areas into “cells.” Through radio waves, wireless devices may connect to the internet and a telephone network through the local antennas that make up each cell. 5G achieves its lightning-fast speeds by using millimeter waves.

Millimeter waves, also known as mmWaves or high-band 5G, are electromagnetic waves with a frequency of 24 GHz or higher. The wavelength of a radio wave decreases as its frequency rises. Due to its high frequencies, mmWave can only reach 300 to 500 feet in range and has trouble penetrating structures. 3G and 4G networks, on the other hand, can reach further distances and penetrate more solid objects, such as walls and ceilings.

Only satellite and radar systems, mostly run by the military and aerospace industries, made use of millimeter waves until recently. The industry saw the necessity and potential to use millimeter waves for the next generation of mobile networks as data demand skyrocketed.

In 2019, mobile phone companies began rolling out 5G networks. Several areas in the US now have access to 5G. By 2025, although 2G and 3G are still in use, 5G networks are expected to have billions of users.

What can we achieve with 5G?

1. Improved mobile broadband: 5G might allow on-the-go, ultra-high-definition video, virtual reality, and other sophisticated applications.
2. Internet of Things (IoT): The explosion of linked gadgets, from smart refrigerators to industrial shop floor battery monitors, has overwhelmed existing cellular networks. 5G will enable considerably more low-power IoT connectivity.
3. Mission-critical control: Vehicle safety systems and medical gadgets are increasingly using connected devices for dependability. Time-critical applications will be more dependable with 5G’s decreased latency and robustness.

Why is 5G so important?
The four business sectors that will most likely be transformed by 5G are as follows:

1. Intelligent mobility solutions, such as car sharing, public transportation, infrastructure, hardware, and software, will be powered by connectivity.
2. With increased connectivity, the healthcare business has the potential to evolve. Robotic surgery may benefit from data flow and low-latency networks. AI-powered decision support systems may provide quicker and more accurate diagnoses, as well as automate duties, allowing caregivers to spend more time with patients.
3. Private 5G networks enable new manufacturing and other industrial processes. In a smart factory, AI, analytics, and sophisticated robots are combined to optimize operations in real time. High-band 5G speed and latency are required for self-driving trucks, as well as bin selection and quality control enhanced by computer vision.
4. Retailers can use sensors, trackers, and computer vision to monitor inventory, warehouse operations, and supply chain coordination.
