Have you ever paid attention to the numbers next to your Wi-Fi sign Have you read 3G, 45, 5G Do you know what these letters and numbers mean?
It is proof of the recent development in wireless networks, as it means that each number of them means the generation attributed to it from the generations of cellular wireless communications until it develops according to specific standards and provides a solution faster than one network to another, and it clearly shows the difference between each generation and another, all to meet the huge demands for communication and to take care of new applications Which is increasing rapidly in the world of technology, which makes us always need an increase in speed and the right information flow.
In this article, you will find an explanation of the latest, most advanced, fast and secure networks, the fifth generation computer systems, which have been specially made to keep pace with the massive development of new applications and other digital experiences (such as online games, video conferencing, and self-driving cars).
With very high data flow (several gigabytes), to give high interaction (short wait time of a few milliseconds) and high reliability, it is specifically designed to increase speed, reduce response time and improve the resilience of wireless services.
The tremendous development appears in the difference between two successive networks, 4G and 5G, where the difference between the two networks is evident in an attempt to keep pace with development and achieve a balance between modern technologies and the communications network, as 5G technology has a maximum speed of 20 gigabits per second while the maximum speed of fourth generation technology is one gigabyte per second. second only. Of course, here I noticed the extent of development that occurred only between two successive networks, to explain to you more about the beginning of communication networks, and then move on to explaining the fifth generation computer systems.
First, the evolution of wireless networks:
The evolution of wireless networks has occurred through the gradual introduction of new technologies, each addressing the shortcomings of its predecessor. Older systems used analog radio technology to transmit voice or data signals over long distances without the need for physical connections between stations. Digital technology replaced this technology in the 1990s, and it is now being replaced by the fifth generation (5G) standard.
How did it all start
In the late 19th century, physics professor Nikola Tesla discovered radio waves. In 1895, it was able to transmit signals a distance of one mile as the first wireless communication in history.
The evolution of wireless networks over time has been largely driven by increased consumer demand. “The 'one-size-fits-all' approach to enterprise networking is no longer feasible," said Sanjay Uppal, Vice President and General Manager, HPE Networking.
Wireless network technologies such as 3G, 4G, and 5G have evolved over time.
The first wireless networks were cellular networks and used a wide range of frequencies across the electromagnetic spectrum, from about 800MHz to 2GHz. Cellular networks have made it possible for people to make phone calls using cell phones when they are away from their landline phones at home or at work.
What is the fifth generation of computer systems
Whereas previous generations of cellular technology (such as 4G LTE) focused on connectivity, 5G takes connectivity to the next level by providing connectivity experiences from the cloud for customers. 5G networks are software-based virtual networks that use cloud technologies.
5G will also simplify mobility, providing seamless open roaming between access from one Wi-Fi network to another, where they can stay connected even outside the building without user intervention or the need to re-authenticate considering cost and available capabilities.
5G technology should improve connectivity in underserved rural areas and in cities where demand can exceed 5G capabilities. New 5G networks will also have a dense and distributed access architecture, bringing data processing closer to the network edge and for users to enable faster data processing.
How does 5G technology work?
5G technology will deliver updates across the network architecture. The 5G New Radio standard, the global standard that provides a high-capacity 5G wireless aerial interface, will cover spectrums not used in 4G networks. The new antennas will incorporate a technology known as Massive MIMO (Multiple Input, Multiple Output) technology, which enables multiple transceivers to transmit more data at the same time.
But 5G technology is not just limited to new wireless spectrum, it is designed to support a converged and heterogeneous network that includes both licensed and unlicensed technologies and this will increase the bandwidth available to users.
The 5G architecture will be software-defined interfaces in which the business function is managed by software rather than hardware. Advances in virtualization services, cloud-based technologies, information technology, and business automation will enable 5G to become a flexible and resilient network that provides access to users anytime and anywhere.
5G networks can create software-defined subnetwork structures known as network segments. These network segments enable network administrators to define network functions based on users and services.
5G technology is also improving digital experiences through machine learning and meeting the demands of accelerating response times to milliseconds (as in self-driving cars) requires that 5G networks integrate automation with machine learning and eventually with deep learning and artificial intelligence. Proactive provisioning and management of data traffic and services will reduce the cost of infrastructure and enhance the connectivity experience.
Some of the benefits of using Fifth Generation Computer Systems technologies:
1 - Holographic Meetings:
The 5G network will allow meetings to be delivered using hologram technology at a high speed so that employees of a particular organization, regardless of the country in which they reside, can come together as if they were in one place.
2- High speed gaming and download speed:
The 5G network will enable people to play high-volume games on their smartphones in high quality, after it was previously difficult to access these games only after downloading them to the PC. It will also allow downloading large size movies in a few seconds.
3- Smart homes:
Smart homes will use the 5G network to connect and control devices wirelessly via a phone, without the need to connect these devices to a central computer.
4- Self-driving cars:
Self-driving cars could use the 5G network to exchange information with each other, which could help reduce congestion, for example.
5- Surgical operations:
Experts say this new network could allow doctors to perform remote surgeries using robots and the Internet.
Regulatory and healthy framework
5G follows the international guidelines of the International Committee for the Protection of Non-Ionizing Radiation and the Institute of Electrical and Electronic Engineering recognized by the World Health Organization. The frequencies used in 5G are part of the radio frequencies that have been devoted to thousands of studies for more than 20 years. After a systematic analysis of all these studies, national and international health authorities have concluded that there are no specific risks to health below the thresholds set in international guidance, and thus the integrity of the regulatory framework for the 5G network, which is now available for many phones and mobile networks, and which is in constant acceleration and race To catch up, it was guaranteed.
