What is 5G network and Amazing Benefits of 5G Network

In a world of instant gratification, the need for faster internet has grown exponentially.

4G was designed with a maximum download connection speed of 100 megabytes per second and a maximum upload connection speed of 50 megabytes per second. 

The need for a more reliable connection and a higher download speed is a priority for many people. 

5G, the newest network, has a maximum download connection speed of 10 gigabytes per second with a maximum upload connection speed of 4 gigabytes per second. 

With 5G, you will be able to watch movies in a matter of seconds and be able to download the latest song in seconds as well. 

This increased download and upload speed will allow for the instant gratification many people are looking for in today’s digital world.

5G is the next big step for developers. The high speed and low latency have a big advantage for developers. 

When 4G was introduced, people were surprised/delighted by the speed of the network and the way it worked. 

Later with the emergence of LTE (Long Term Evolution), more content was available for streaming videos and live gaming.  

What is 5G network and its Benefits in more details

5G offers a speed of 50-100 MBps and a latency of less than one millisecond across the wireless spectrum. 

It also offers the ability to use different frequency bands, harmonious with the ongoing use of spectrum in 4G.

5G networks are here to stay!

The next-generation mobile internet is almost here! 5G networks will be ten times faster than your current 4G.

5G is poised to transform cities, connect cars, enable drones, and, along with IoT & AI, usher in the next industrial revolution.

5G networks will also lead to a more connected smart world. 

This means that you’ll be able to seamlessly connect with devices such as drones and cars and have more seamless connections with the internet, as well as other people.

Advantages of 5G

5G is a promising technology that has the potential to revolutionize wireless communication. With 5G, we will be really able to harness the power of IoT (Internet of things). 

It promises to provide faster data rates, lower latency, and greater energy efficiency. 

These improvements should enable new applications, services, and experiences.

-Higher data rates: 5G promises to deliver much higher wireless data rates than existing 4G standards.

-Lower latency: 5G promises to provide much lower latency than existing 4G standards.

-Greater energy efficiency: 5G promises to consume much lower power than existing 4G standards.

-New applications: 5G promises to enable new applications that are not possible under current standards.

 It will enable new ways to use the internet, and even new industries could be created.

 5G can provide a speed of 20 Gbps with the help of enhancing mobile broadband. This will be very helpful for applications that need high bandwidth in virtual reality and augmented reality.

How does it work?

While using wireless communication systems, information is carried through the air using radio frequencies (known as a spectrum).

5G also uses the same method, but it has higher radio frequencies and is less cluttered. Therefore, more information is carried at a faster rate. Millimetre waves are used for this process.

The shorter the wavelength, the higher the frequency.

Currently 2G, 3G and 4G operate on different frequencies across a range from 800MHz right up 2,600MHz.

5G signals will use wavelengths (between 30 and 300 gigahertz) that are measured in millimetres.

While higher bands are faster at carrying information, there can be problems with sending over large distances. They are easily blocked by physical objects such as trees and buildings.

To solve this challenge, MIMO (multiple input, multiple output) concept is used.  

MIMO is an antenna technology for wireless communications. Here multiple antennas are used at both the source (transmitter) and the destination (receiver).

The antennas at each end of the communications circuit are combined to minimise errors and optimise data speed.

Taking your slice of the network

With 5G, you can get ‘a SLICE of Network’, dedicated to you.

So, with 5G, a dedicated piece of the spectrum will be provided to customers…that is a guaranteed level of service.

This will be very useful in the healthcare industry (if you are taking help of video, to get instruction from a doctor/expert during surgery or in case, the surgical robot is at work).

In these scenarios, you are offering, the capability of cellular & guaranteed quality of service (in terms of security & privacy).

5G and the Concept of Programmability

With 5G, network providers/operators will be able to provide, a lot of flexibility& a diverse range of services. And programmability will be central to achieving this.

5G networks will be programmable, flexible, modular, software-driven and managed in a holistic fashion.

Today, the compute/processing power is within the network. So network does all the processing work (Like managing the subscription layer of your customer, customer’s identity management, content management & distribution of the content around the network).

Now, what if, we can push all that work, away from the core network & near the customer. That’s put computing power and processing power into the base stations at the site.

This concept goes by the name of edge computing and it is achieved with SDN (Software-defined Networks) and NFV (Network function virtualization).

It’s about moving away from the limitations of hardware and to a very flexible and readily upgradable software capability.

Role of SDN & NFV in 5G architecture

With software-defined networking (SDN) and Network Functions Virtualization (NFV) supporting the underlying physical infrastructure, 5G comprehensively cloudifies access, transport, and core networks.

SDN has been proposed as a promising technique for these networks, which will be a key component in the design of 5G wireless networks.

The 5G is going to be based on a user-centric concept instead of operator-centric as in 3G or service-centric as seen for 4G.

And with help of SDN and NFV, a big part of 5G technology will have multiple hierarchies, which will constitute the network topology.

SDN technology utilizes software-defined centralized network management and dynamic network configuration programming.  With this, operators will be able to give scalability and flexibility for 5G network provisioning and end-to-end network performance and monitoring.

SDN architecture is structured on three primary layers.

  1. Data plane: This consists of the network elements,
  2. Control plane: This acts as the central Controller
  3. Application plane: This consists of the different applications.

The basic SDN principle is based on the separation of the data plane from the control plane and the logical centralization of all the control functions.

The SDN controller can provide a more centralized approach and an end-to-end view on the 5G network chain.  The main concept is that each application communicates with the network directly via an interface to the central Controller without the need to communicate with each network element.

The Controller can monitor the network centrally, propose changes in the requirements, and implement any re-configuration needed.  So, it acts as a central control instance between the application and the network. 

So, the SDN controller can suggest the optimum route across multiple domains by calculating the path with the shortest delay based on latency measurements on the network.

SDN provides a programmable approach, where the features and functions of the network are not limited to the capabilities of the network elements.

Now they can be complemented by new processes developed on demand and per request by the network operator. 

So, in essence, with centralized decisions, now the Controller can implement, the appropriate changes that result in an efficient automated manner and optimum 5G network utilization.

SDN can give a competitive edge to 5G network operators by combining NFV and the cloud, to support a flexible and scalable 5G network. 

With SDN and NFV, it is possible to use virtual networks whose topology is independent of the hardware network on which they are based. 

NFV (Network Function Virtualization), represents a framework for a modern network architecture in which high-performance and high-capacity hardware is virtualized This allows multiple virtual instances (VMs, virtual machines) to share a pool of resources within the virtualization layer.

NFV is the process of decoupling the network functions from proprietary hardware appliances.

These functions (such as firewall, deep packet inspection, and intrusion prevention) become virtual network functions (VNF).

Here, software-based functions take over the role of the network element and are controlled by an element manager network system.

NFV helps service providers or operators to virtualize functions like load balancing, routing, and policy management by transferring network functions from dedicated appliances to virtual servers.

As of now, many countries including South Korea, China, Canada, and the United States have confirmed rollouts of 5G. 


5G is a next-generation wireless technology that is also called the “Fifth Generation wireless network.”

This new technology will be able to deliver broadband speeds that are ten times faster than the current 4G LTE.

 In order to achieve these speeds, 5G will be able to support streaming 4K videos and other broadband services.

It’s expected that the rollout of 5G will happen over the next couple of years.

5G will offer significant benefits for consumers and businesses. The speed of the service will be much faster than 4G, and 5G will be able to provide broadband speeds to more people.

 This will enable consumers to stream high-quality content and use other broadband services. Also, along with IoT & AI, it will usher new possibilities/useful solutions in healthcare, personal education, security & transportation etc.
