#first. What is 2G network?
2G networks, or wireless networks using the second method of data transmission, have appeared in our country since the 1990s. The speed of 2G networks ranges from 50kbps to 1mbps. Very slow compared to the present time, huh.
If you are 8x or 9x, you probably cannot forget such advertisements GPRS to send 8730 It's legendary, isn't it? That's the same syntax for 2G network registration.
Network 2G use frequency band EDGE, and 2.5G use frequency band GSM. Ie network E or network G on Nokia's previous feature phones.
The network has ever released 2G Data Packs with 25MB for 10,000 VND, used all month. This is enough network capacity on a machine with a screen resolution of only 360 × 480, not up to several million pixels as now.
2G network has many limitations such as low speed, high cost, and the connection quality is easily affected…. So since the Smartphome was born, plus the bigger phone screens, the 2G network quickly became outdated, and was replaced very quickly by the 3G or 4G network.
#2. Why stop 2G network?
Very simple: Prepare infrastructure for 5G network!
Our country will be one of the first countries to pioneer for widespread coverage of 5G networks, so it is necessary to kill 2G networks to be able to widen the band of current 3G and 4G networks, and also to deploy the network. 5G is more favorable.
Feature phones are many, but not many people use this network. Devices that only support 2G and 2.75G networks currently only have some old Nokia models, running Java operating systems such as Nokia 2730, Nokia 6300, Nokia N3, etc., which means “ bricks ”but captured the image, according to the user’s perspective.
Content on the Internet has also gradually lost support for Java browsers, and there is almost no application developer for the platform. In short, the Feature phone is a brick that can capture images, that's all.
Our country is planning to turn off the entire 2G network in the next few years, but this has been done by carriers in the US, South Korea and Japan for decades.
That is why the quality of mobile data network over there is very good, because there is good signal infrastructure and a lot faster than our country.
# 3. Those who will be affected when the 2G network is turned off
Yes, of course those who are using “Brick” phones, people in remote areas have very very low income!
Turning off 2G signals will turn "brick" phones into useless items. Basic operations such as listening, calling or texting will no longer be used.
# 4. Conclude
In short, work turn off 2G network in Vietnam is perfectly reasonable, because before anything will have to do. Moreover, the number of users affected is not much, and this is also necessary for the development of Vietnam's Smartphone market, as well as the quality of our country's mobile network.
