For many years, engineers have been working on a new wireless technology called 5G. Now, it is getting closer to becoming widely used.
Although it’s not available everywhere yet, most of the top smartphones can now connect to 5G. So, if you have one of these phones, you’ll probably notice a 5G symbol on your screen quite often.
5G is not just a new number; it’s a more complex technology for carriers to introduce. It uses a wider range of frequencies compared to older 4G/LTE technology, and each frequency has its own advantages and disadvantages.
Additionally, 5G has a broader reach, offering the possibility of worldwide connectivity, something that was once only seen in futuristic sci-fi books.
The buzz around 5G might make you wonder what it is, but don’t worry, it’s not too complicated for regular people. It’s mainly about checking if 5G works where you live and work, getting a good 5G phone, and choosing the right 5G cell phone plan.
But because 5G has some amazing new features, understanding how it works can help you make better decisions. Here’s all you need to know about 5G.
What is 5G?
5G is the fifth generation of wireless technology for mobile communication. It’s an improved and faster version of the previous 4G networks. 5G provides faster data speeds, lower latency (less delay), and higher capacity, which means it can handle more devices and data traffic at once.
Moreover, this technology is designed to offer better connectivity and support new applications like virtual reality, augmented reality, and the Internet of Things (IoT).
In simpler terms, 5G helps us access the internet and communicate with each other more quickly and smoothly.
How does 5G Work?
The fundamental working principles of 5G are more complex than previous generations.
It involves a sophisticated network architecture and advanced technologies to achieve its exceptional performance. The 5G network consists of three main components:
- 5G Radio Access Network (RAN)
The Radio Access Network (RAN) is responsible for transmitting and receiving wireless signals between the user equipment (UE) and the core network.
In 5G, the RAN is designed to use both macrocells (larger cell towers) and small cells (compact base stations) to improve coverage and data speeds. Small cells are especially important in urban areas with high user density.
- 5G Core Network
The 5G Core Network is the central part of the 5G system, responsible for managing data traffic, network services, and user authentication.
One of the key features of the 5G Core Network is Network Slicing, which allows the network to be divided into multiple virtual networks tailored for specific use cases.
Each slice can have different characteristics, such as bandwidth, latency, and security, optimized for various applications like industrial automation, entertainment, and healthcare.
- 5G Protocol Stack
The 5G protocol stack consists of a set of communication protocols that enable the flow of data between different layers of the network. This stack is more advanced than the one used in 4G, allowing for faster and more efficient data transfer.
The protocol stack in 5G is divided into three main layers: the Physical Layer, the MAC (Media Access Control) Layer, and the Application Layer.
Key Differences between 3G, 4G, and 5G
|Data Speed||Up to 2 Mbps||Up to 100 Mbps||Up to 20 Gbps|
|Latency||Around 100 ms||30 – 50 ms||As low as 1 ms|
|Bandwidth||Up to 5 MHz||Up to 20 MHz||Up to 400 MHz (mmWave) <br> Up to 100 MHz (sub-6 GHz)|
|Connection Density||Up to 2,000 devices per square kilometre||Up to 20,000 devices per square kilometre||Up to 1,000,000 devices per square kilometre|
|Spectrum Bands||Primarily uses sub-1 GHz and 1-2 GHz bands||Utilises 700 MHz, 1.8 GHz, 2.1 GHz, 2.3 GHz, 2.6 GHz, and other bands||Utilises both high-frequency millimetre wave (mmWave) bands and sub-6 GHz bands|
