The rapid advancement in technology has propelled the world into the era of seamless communication and unlimited connectivity. The introduction of the 4G network, also known as the fourth-generation wireless network, revolutionized the way we access the internet and communicate with one another. 4G stands for “fourth generation,” signifying the fourth major iteration of wireless technology. It is a successor to the 3G network and promises faster speeds, broader coverage, and enhanced capabilities. 4G networks are designed to provide high-speed mobile internet access to users, enabling them to stream videos, download files, engage in video calls, and browse the internet effortlessly. There are two primary types of 4G networks: LTE (Long Term Evolution) and WiMAX. LTE is the most widely adopted 4G technology, offering impressive data transfer rates and seamless connectivity. On the other hand, WiMAX, though less prevalent, is known for its wider coverage area. Both LTE and WiMAX networks deliver significantly faster internet speeds compared to their predecessors. 4G networks boast average download speeds ranging from 10 to 50 megabits per second (Mbps), with peak speeds exceeding 100 Mbps in ideal conditions. These speeds facilitate the smooth functioning of a wide range of applications and services, contributing to a more connected and technologically advanced society.
The telecommunications industry is growing and the speed of accessing data on mobile networks is increasing day by day. Today let’s find out with Thptlaihoa.edu.vn what is 4G network and is its speed really fast?
What is 4G network?
4G (4-G), short for Fourth-Generation, is the fourth wireless communication technology, allowing data transmission at maximum speeds under ideal conditions up to 1 to 1.5 Gb/s. The name 4G was coined by IEEE (Institute of Electrical and Electronics Engineers) to express the meaning “3G and beyond”.
With diverse applications such as high-speed web browsing, IP telephony (VoIP), games, high-definition television, video conferencing… 4G is a promising technology to create new breakthroughs in services. telecommunication.

How fast is 4G network?
4G speeds are meant to be far ahead of 3G. The maximum speed of 3G is: 14 Mbps download and 5.8 Mbps upload. To reach 4G technology, speeds must reach 100 Mbps for mobile (or mobile) users and 1 Gbps for fixed (non-moving) users.

Currently, most mobile devices sold on the market support LTE technology to connect 4G services, some are not even equipped with the old 2G or 3G connection standards.
Some commonly used LTE CAT bands
LTE Category (LTE CAT 3):
+ Download speed is 100 Mbps (100 Megabits/s): The actual transfer speed is 12.5 MB/s, equivalent to downloading a 1 GB movie with a time of 82 seconds.
+ Upload speed (Upload) 50 Mbps (50 Megabits/s): The actual transfer speed is 6.25 MB/s, equivalent to uploading a 1 GB file to the network with a time of 163.84 seconds.
LTE Category 4 (LTE CAT 4):
+ Download speed is 150 Mbps (150 Megabits/s): The transmission speed is 18.75 MB/s, which means you can download a 1 GB file in 54.6 seconds.
+ Upload speed is 50 Mbps (50 Megabits / s): The transfer speed is 6.25 MB / s equivalent to uploading 1 GB file to the network with a time of 163.84 seconds.
LTE Category 5 (LTE CAT 5):
+ Download speed (Download) is 300 Mbps (300 Megabits / s): The transmission speed is 37.5 MB / s => download a 1 GB movie with a time of 27 seconds.
+ Upload speed (Upload) is 75 Mbps (75 Megabits / s): There is an actual speed of 9,375 MB / s => uploading 1 GB with a time of 109 seconds.
LTE Category 6 (LTE CAT 6):
+ Download speed (Download) is 300 Mbps: Equivalent to the speed of LTE CAT 5 with a transmission speed of 35.5 MB/s.
+ Upload speed (Upload) is 50Mbps: Equivalent to Cat 4 is 6.25 MB per second.
LTE Category 7 (LTE CAT 7):
+ Download speed (Download) is 300 Mbps: Equivalent to the speed of LTE CAT 5 with a transmission speed of 37.5 MB/s.
+ Upload speed is 150 Mbps: faster than CAT 6 with a transfer rate of 18.75 Megabytes per second. Uploading a video with a capacity of 1 GB to Youtube in a very fast time of only 55 seconds.
Note : These are only theoretical parameters of the product, the actual speed depends on many other factors such as transmission line, wave, carrier, … and currently LTE supports up to CAT 20.
How to use 4G network?
To establish a 4G network connection, both directions are required: the high-speed network and the device that supports it. Before service providers can support LTE access speeds throughout the region or territory, there will inevitably be a wave of terminal devices (phones, tablets, etc.) connect ability.
Next, carriers will gradually officially provide the new connection standard in a limited way before deciding on full coverage.
LTE is a significant step forward in the development of technology to support wireless connectivity, with outstanding advantages in speed and network optimization.
Up to now, 4G LTE network has covered everywhere, typically in Vietnam, major mobile networks have supported: Mobifone, Vinaphone, Viettel, Vietnamobile with easy-to-access packages.

In conclusion, 4G network refers to the fourth generation of mobile network technology, which offers faster and more reliable wireless communication. It provides increased bandwidth and improved internet speeds compared to its predecessors. There are two main types of 4G networks, namely LTE (Long Term Evolution) and WiMAX (Worldwide Interoperability for Microwave Access). LTE is the widely adopted 4G standard globally, while WiMAX is mainly used in certain regions. The speed of 4G networks can vary depending on various factors such as network congestion, signal strength, and the specific technology used. However, on average, 4G networks can deliver download speeds ranging from 5 to 50 megabits per second (Mbps), and upload speeds from 2 to 25 Mbps. These speeds enable seamless streaming of high-definition content, smooth video calling, fast file downloads, and efficient browsing experiences on mobile devices. With the advent of 4G technology, users have witnessed a significant improvement in their mobile connectivity and internet usage, revolutionizing the way we communicate and interact in the digital age.
