Like the terms 2G, 3G, 4G stands for Fourth-Generation, wireless communication technology fourth generation. 4G support data transfer speeds up to 1 to 1.5 GB / sec, in ideal conditions. And this rate is much higher than 2G and 3G.

From achieving maximum line speed, the 4G network is ideal for users to conduct video conferencing, high definition TV, web browsing speed or even IP telephony (VoIP).

2. 4G network speeds reaching up to how much?

  Download (Mbps)   Upload (Mbps)
LTE CAT 1 10 5
LTE CAT 2 50 25
LTE CAT 3 100 50
LTE CAT 4 150 50
LTE CAT 5 300 75
LTE CAT 6 300 50
LTE CAT 7 300 150
LTE CAT 8 1200 600

As mentioned data transfer speeds higher than 3G 4G. The speed of 3G when the user is 14 Mbps download and 5.8 Mbps upload. And with 4G as mobile users will be 100 Mbps and 1 Gbps for fixed users.

3. The maximum speed of some band LTE CAT

  • 1. Category LTE (LTE CAT 3)

Download speeds of 100 Mbps (Megabits 100 / sec): the actual transfer rate of 12.5 MB / s is equivalent to 1 film download 1 GB storage and 82 seconds of time.

Upload speeds of 50 Mbps (Megabits 50 / sec): the actual transfer rate of 6.25 MB / s is equivalent to download a 1GB file on the network with time 163.84 seconds.

  • 2. Category 4 LTE (LTE CAT 4)

Download speeds of 150 Mbps (Megabits 150 / sec): Transfer rate is 18.75 MB / s can download one file with 1GB time 54.6 seconds.

Upload speeds of 50 Mbps (Megabits 50 / sec) transfer rate of 6.25 MB / s can download 1 GB file 1 time online with 163.84 seconds.

  • 3. LTE Category 5 (CAT 5 LTE)

Download speeds of 300 Mbps (Megabits 300 / sec) transfer rate of 37.5 MB / s download 1 movie with 1GB time 27 seconds.

Upload speed (Upload) is 75 Mbps (Megabits 75 / sec): There is actual speed is 9375 MB / s upload 1 GB with 109 seconds duration.

  • 4. LTE Category 6 (LTE CAT 6)

300 Mbps download speed: equivalent to the speed of LTE CAT 5 transmission rate is 35.5 MB / s. 50Mbps upload speed: Equivalent to Cat 4 6.25 MB per second.

  • 5. LTE Category 7 (LTE CAT 7)

300 Mbps download speed: equivalent to the speed of LTE CAT 5 transmission speed of 37.5 MB / s.

Len150 Mbps download speed: faster CAT 6 with transfer rate is 18.75 megabytes per second. Upload a video with 1GB on Youtube with just 55 seconds of time.

However, this speed depends on many factors such as transmission lines, wave, national carriers.

4. Conditions for using the 4G network?

To be able to register the 4G network, first of all we need to ensure that you are using equipment that supports 4G and support high-speed network. So how to know your device to use the 4G network. We can check the device information to check if you are using a smartphone can register 4G or not.

5. Note the registration of Viettel 4G

The equipment is used to support 4G Subscribers to prepaid roaming, active 02 pm and had time activation use from 60 days (as of the time of day 00h00 27/12/2016)
After switching sim sim 4G Viettel will be white, you need to save your contacts and messages needed before bringing change sim go Sim 4G supports both 3G and 2G networks should be able to use normal

6. Procedures 4G sim change
