What is 4G network? What is LTE network? How fast is 4G network speed?
The telecommunications industry is growing and the speed of accessing data on mobile networks is increasing day by day. And the 4G network, the LTE network appeared, bringing the 4th generation mobile Internet connection technology, helping phones or laptops connect to the network with speeds that can be 7 to 10 times faster than 3G networks. Learn about 4G network through the article below!
1. What is 4G network?
4G network is the abbreviation of Fourth-Generation , this is a wireless communication technology that allows maximum data transmission up to 1–1.5Gb/s under ideal conditions. The established standards for 4G connectivity, issued in March 2008 by the International Networking Organization ITU-R, require all services with 4G to comply with a series of transmission line standards. degree and connection.
2. What is LTE network?
LTE network is the English term called Long Term Evolution , which is roughly understood as “Long Term Evolution”. LTE network is not considered a network technology, instead LTE is just a technology standard improved from the GSM.UMTS standards.
More specifically, LTE network is the standard next to 4G network technology. When your mobile device is connected to LTE, there will be an icon like 4G in the corner of the screen. Currently, the LTE technology standard impresses users with high and strong network speed and capacity.
3. What is 4G LTE network?
4G LTE network is a type of communication network that is not yet a 4G standard technology, but instead is just an asymptote to the fourth network technology. When a connection has data transmission at up to 1 or 1.5 Gb/s, it is considered a 4G network.
Currently, there is no network device or smartphone that can achieve such transfer speeds. This has caused carriers to add the word “LTE” to help users understand that this is just a standard technology close to 4G network technology.
4. 4G and 4G LTE the same or different?
The answer to this question is definitely different because 4G LTE is just a faster connection than 3G and has not yet reached the ideal data download speed like the 4G network in the research benchmark. In other words, 4G LTE offers much lower speeds than a true 4G network. However, the data transmission of 4G LTE between smart devices through this connection network has improved significantly compared to the time of GPRS network.
5. Benefits of 4G . network
Faster speed
Standard 4G (or 4G LTE) is about 5–7 times faster than 3G. This network offers theoretical speeds of up to about 150Mbps. To make it easy to imagine, with 4G LTE, you can download a 2GB HD movie in 3 minutes and 20 seconds, while with standard 3G it takes more than 25 minutes.
Lower latency
Besides download speed, 4G network also has better response time than 3G network thanks to lower latency. According to the published specs, the 4G network is reduced from 80 milliseconds (this is the latency of 3G) to about 45 milliseconds. This is most evident when you play online games and stream live videos (Livestream).
Better call signal
Through the 4G network platform, voice and video calls will be sharper and clearer thanks to the fast and strong network speed. Plus, you can call and text when you only have a 4G connection, something you couldn’t do before.
6. How fast is 4G network speed?
4G network speed far exceeds 3G network. To achieve 4G technology, network speeds must reach 100 Mbps for mobile users (who are on the go) and 1 Gbps for fixed users (who are not on the move).
Currently, most of the mobile devices sold on the market support LTE technology to connect to 4G services, some are not even equipped with the old 2G or 3G connection standards.
7. Some Commonly Used LTE CAT Bands
Note : These are only theoretical parameters of the product, the actual speed depends on many other factors such as: Transmission line, wave, carrier,…
- 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) is 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 is 300 Mbps (300 Megabits/s): The transmission speed is 37.5 MB/s, equivalent to downloading a 1 GB movie with a time of 27 seconds.
+ Upload speed is 75 Mbps (75 Megabits / s): There is an actual speed of 9,375 MB / s, equivalent to 1 GB upload 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/s.
- 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 MB/s ( What is MB ? — is a multiple of byte units). Uploading a video with a capacity of 1 GB to Youtube in a very fast time of only 55 seconds.
8. List of carriers that support 4G
Currently, all network operators in Vietnam are supporting 4G network technology, leading among them are Viettel , Vinaphone , Mobifone , Vietnamobile . The packages of each carrier will have an appropriate price, enough services to meet the needs of users.
9. Conditions for using 4G mạng network
4G SIM registration
To use 4G network, you must subscribe to 4G SIM service. You can access the app of the carrier corresponding to your SIM to get detailed information. For example, Viettel operator accesses the My Viettel application, MobiFone operator accesses My MobiFone application, VNPT operator accesses My VNPT application, and Vietnammobile operator accesses My Vietnamobile application.
Alternatively, you can visit carrier websites, social media channels or nationwide stores to register for a 4G SIM. You just need to go to the carrier’s service points, request to change to 4G SIM and register for a package to be able to use it.
4G enabled mobile device
In addition, to use 4G network, your phone must be supported for this network. Most of today’s high-end smartphones from LG, Sony or Samsung support 4G LTE. Even mid-range smartphones like Lenovo, OPPO , Meizu or Xiaomi have the ability to connect to 4G LTE networks. Therefore, you need to read the device’s specifications clearly, or ask the salesperson to search for you before deciding to buy.
