5G is the new technology. You need to know about 5G.
Introduction
In the new technology world of smartphones, staying ahead of the curve means adopting the latest innovations. Among these, 5G stands out as the latest technology for lightning-fast speeds, unlimited connectivity, and improved user experiences. But what exactly is 5G? and how does it transform the way we use our smartphones? Now we'll explore deep how it works, and the various benefits it offers to consumers worldwide.
History of 5G
The fifth generation of mobile network technology innovated in the early 2010s. In 2018, 5G deployments began in the United States.The first commercial 5G network launched in South Korea in April 2019. Verizon was the first carrier to roll out 5G in 2019 in Chicago and Minneapolis., In 2020 all EU countries had commercial 5G launches, except for four. This networks have since been rolled out in many other countries, including China, Japan, and parts of Europe.
What is 5G?
5G is short for the fifth generation of wireless technology and represents a significant jump forward from its predecessors for Ultra-fast speeds, ultra-low latency, and outstanding connectivity. It isn't just about faster download and upload speeds. It's about opening more opportunities through unlimited connectivity and real-time interactions. You can know about more in Qualcomm.
How does 5G work?
5G networks utilize advanced antenna systems with dozens or more hundreds of antenna elements. This technology is known as MIMO (Multiple-Input Multiple-Output) for more efficient use of the available spectrum and improved data transmission rates.
5G uses beamforming techniques , which focus the radio signal in a specific direction, rather than broadcasting it in all directions. This focused transmission not only improves coverage but also enhances overall network capacity and efficiency.
5G can combine multiple carriers (frequency bands) to create a wider data pipeline for increasing the available bandwidth and supporting higher data rates.
One of the most exciting features of it is network slicing, which allows carriers to create multiple virtual networks on top of a single physical infrastructure. This helps the customization of network resources and capabilities based on specific use cases, such as enhanced mobile broadband, ultra-reliable low-latency communications, and large machine-type communications.
5G Band
Low-Band (Below 1 GHz):
Bands: 1, 2, 3, 5, 8, 12, 13, 14, 20, 28, 66, 71 (depending on carrier)
Frequency Range: 600 MHz - 900 MHz
Speeds: Up to 100 Mbps
Benefits: Excellent coverage, good for basic tasks like web browsing and social media.
Coverage Area: ( Up to 10 km from Cell Tower ) Low-band frequencies are used for extensive coverage and penetrate buildings and obstacles for providing wide-area coverage in urban, suburban, and rural areas.
Drawbacks: Slower speeds compared to mid and high-band.
Mid-Band (1 GHz - 6 GHz):
Bands: 7, 25, 26 (3.5 GHz), 40, 41 (2.5 GHz), 75, 78 (3.5 GHz)
Frequency Range: 1 GHz - 6 GHz
Speeds: 100 Mbps - 1 Gbps
Benefits: Good balance between coverage and speed, suitable for streaming, video calls, and downloading.
Coverage Area: ( Up to 1-5 km estimated from Cell Tower ) Mid-band frequencies hit a balance between coverage and speed for faster data rates than low-band frequencies but provide lower coverage than low-band.
Drawbacks: Coverage might be less extensive than low-band, but wider than high-band.
High-Band (Above 6 GHz):
Bands: 28 (28 GHz), 38 (24 GHz), 77 (38 GHz), 79 (mmWave)
Frequency Range: Above 6 GHz ( 24-47 GHz )
Speeds: Up to 20 Gbps (theoretical)
Benefits: Ultra-fast data speeds for activities like downloading large files and high-definition video streaming.
Coverage Area: ( Up to 100-900 meters estimated from Cell Tower ) High-band frequencies, also known as mmWave, are used for ultra-fast speeds and the lowest latency of any band.
Drawbacks: Limited coverage due to shorter signal range and difficulty penetrating buildings and trees.
5G SA/NSA
SA (Standalone) is the true future of 5G. It utilizes a completely new network architecture including dedicated 5G base stations and a brand-new 5G core network. This releases the full potential of 5G for delivering ultra-fast speeds, ultra-low latency, and the ability to support innovative applications like network slicing (creating virtual networks for specific uses) and the Internet of Things (IoT) on a large scale.
NSA (Non-Standalone) approach acts as a bridge between 4G and 5G. It leverages the existing 4G LTE core network but adds a layer of 5G New Radio (NR) technology on top. This allows for a quicker and more cost-effective 5G rollout for carriers. As they can use their existing infrastructure. However, NSA doesn't open the full potential of 5G in terms of speed and latency.
How will you get benefits from 5G?
Ultra-fast speeds: You can wave goodbye to buffering and lengthy download times. Imagine downloading a full-length 4K movie in a few seconds or streaming ultra-high-definition content without waiting. Because it can reach speeds up to 20 GB/s. This level of speed opens up a world of opportunities for content consumption, gaming, and productivity on the go.
Ultra-low latency: Latency or the time it takes for data to travel between devices and the network, is a critical factor in real-time applications. 5G promises latency as low as 1 millisecond helping great experiences in areas like remote surgery, cloud gaming, and autonomous vehicles, where every millisecond counts.
Increased capacity: 5G can support a large number of connected devices simultaneously. From smart cities to the Internet of Things (IoT), it increased capacity provides that every device can communicate unlimited without compromising performance.
Enhanced mobility: 5G has advanced antenna technologies and intelligent network management to help unlimited mobile experience at high speeds. If you're on a high-speed train or in a fast-moving vehicle, it provides a consistent and reliable connection for opening up new opportunities for mobile productivity and entertainment.
