Popularization of Science: The Difference between 5G WiFi and Mobile 5G Signal

My WiFi name has a '5G' after it, is the internet speed going to be super fast? "With the widespread use of 5G, many citizens have raised questions. Regarding this, Zou Xing, a WiFi technology expert from China Mobile, stated that 5G in WiFi means 5G Hz, representing the 5G frequency band, which is not the same as 5G in mobile phones.

We have two common WiFi operating frequency bands, 2.4G and 5G; And 5G on mobile phones refers to the 5th generation communication technology, which is not the same as 5G on WiFi.

Why is there a 2.4G and a 5G after the WiFi name? Previously, routers only had WiFi signals in the 2.4G frequency band, which was very limited. Many devices worked in the 2.4G frequency band, and the interference between signals was significant and the speed was not very fast. With the popularity of fiber optic broadband, many new routers are dual band wireless routers that transmit WiFi signals in both 2.4G and 5G frequency bands.

The 2.4G WiFi signal has a low frequency, longer wavelength, less attenuation during propagation, and is easier to pass through obstacles, resulting in longer propagation distances; However, 2.4G has a narrow bandwidth, high interference, and is prone to congestion. 2.4G WiFi can reach up to 10M/S.

In contrast, 5G WiFi has a wider bandwidth, less interference, fast and stable speed. The newly developed frequency band is like driving to a new urban area, with fewer cars and wider roads, and faster speed; But its ability to penetrate walls is poor, and its propagation distance is close, with 5G WiFi reaching up to 60M/S.

So, if it's closer to the router, we should prioritize using 5G WiFi signals, which will result in faster network speeds. On the contrary, if you are far away from the router, you will find that 2.4G WiFi signal is better, while 5G WiFi signal is almost impossible to connect to.

Network characteristics:

1. The peak rate needs to reach the standard of Gbit/s to meet the transmission of Big data such as high-definition video and virtual reality.

2. The delay level of the air interface needs to be around 1ms to meet real-time applications such as autonomous driving and telemedicine.

3. Super large network capacity, providing connectivity for billions of devices, meeting the needs of IoT communication.

4. Spectral efficiency is 10 times higher than LTE.

5. Under continuous wide area coverage and high mobility, the user experience rate reaches 100Mbit/s.

6. The flow density and connection Number density have been greatly improved.Vehicle Router

7. The level of system collaboration and intelligence has been improved, manifested as collaborative networking with multiple users, multiple points, multiple antennas, and multiple uptake, as well as flexible automatic adjustment between networks.4G Industrial Router

8. At present, most new phones launched by mobile phone manufacturers support 5G networks. First tier cities have already laid out a large number of 5G network communication, while third and fourth tier cities and towns have not yet popularized it.

So, the true popularization of 5G networks will take two to three years.5G Industrial Router
