Adding “5G” after the Wi-Fi name will make the Internet faster?

When connecting to Wi-Fi, many netizens may find that two Wi-Fi signals appear at the same time, one with the "5G" suffix and the other without. Why do the same Wi-Fi have two signals? Does the "5G" after the Wi-Fi name mean faster network speed? Let's find out with the editor~

What does the “5G” after the name of Wi-Fi mean?

In fact, the 5G in the name of Wi-Fi means 5G Hertz (Hz), which represents the 5G frequency band; while the 5G in mobile phones refers to the fifth generation of communication technology, and G means generation; the two "5G" are not the same thing.

The common Wi-Fi we use has two operating frequency bands: 2.4G and 5G. In the past, routers only had 2.4G Wi-Fi signals, which had limited bandwidth and many devices worked in this frequency band, resulting in large interference between signals and low speeds. With the popularization of fiber-optic broadband, dual-band wireless routers have emerged, which can transmit signals in both 2.4G and 5G frequency bands at the same time.

What is the difference between these two frequency bands?

2.4G refers to the signal frequency band between 2.4GHz and 2.4835GHz, which has strong wall penetration ability and longer transmission distance; however, the bandwidth of 2.4G Wi-Fi is narrower and it was developed earlier. Many devices use this frequency band, which has a lot of interference and is relatively crowded, just like encountering traffic congestion during rush hour, and the speed is slower.

The 5G signal frequency band is between 4.910GHz and 5.875GHz, with poor wall penetration ability and a shorter propagation distance than the general 2.4G; but the bandwidth is wider, there is less interference, and the speed is fast and stable, just like driving smoothly on a highway.

Two Wi-Fi signals, how to choose when connecting?

If you are close to the router device when using Wi-Fi and your location changes little, you can prioritize connecting to 5G Wi-Fi, which has a more stable signal and faster network speed.

If your location changes frequently and there are multiple walls between you and the router, please connect to 2.4G Wi-Fi first, as it provides better signal coverage and smoother network.

Note: To use 5G Wi-Fi, mobile phones, laptops and other devices must support dual-band Wi-Fi. Most old desktop computers and TVs can only search for 2.4G Wi-Fi signals.

How to speed up Wi-Fi? A few tips to help you

1. The router is set in the middle of the house

The location of the router is very important. You should try to choose a location in the middle of the house. If it is a two-story building, you can consider fixing it on the wall or in a corner close to the ceiling. Generally speaking, the signal tends to radiate downward, so you can consider setting it on the second floor.

2. Avoid signal blocking

Although the signal can penetrate walls, the thicker the wall, the more the signal will be attenuated. In addition, if the house is made of brick or concrete, the signal will be absorbed by the wall and the signal will be greatly weakened. Similarly, the sink will also greatly absorb and weaken the signal, hindering the propagation. In addition, materials such as metal and mirrors will reflect the signal, and behind the TV and in the bathroom are not the best places to place the router.

3. Stay away from interfering electrical appliances

The electromagnetic waves emitted by microwave ovens and routers are both at 2.4GHz, so using a microwave oven will interfere with Wi-Fi signals. Metal will also absorb signals, so the router should also be kept away from metal objects such as refrigerators and stoves.

In fact, adding "5G" after the Wi-Fi name does not mean that the Internet speed is super fast. The specific Wi-Fi connection should be selected according to different situations.
