The wireless local area network of notebook computer, unexpectedly measured 1.47Gbps! Verify that "Wi-Fi 6" and "three belts" are easy to get out of two compatible network files of the latest router

And another key word-"three bands"-may be a phrase often heard before.

A brief description of that three-band, that is, the radio band that Wi-Fi can use has three systems.

In Wi-Fi, which uses radio waves to communicate, basically in the same space, only one communication using the same frequency can be carried out. Because if multiple terminals communicate at the same frequency, the radio waves will interfere.

However, if you use a Wi-Fi router that supports three bands, you can use Wi-Fi communication in three systems at the same time, such as 2.4GHz band + 5 GHz-1 band + 5 GHz-2 band.

Metaphorically speaking, it can be regarded as a three-lane road. On roads with a small number of lanes, if the number of vehicles increases, there will soon be traffic jams. However, if it is a 3-lane wide road, this congestion can be eliminated, or the additional 1 lane can be used separately for purposes such as overtaking lanes.

Similarly, the three-band compatible Wi-Fi router can use the Wi-Fi of the three systems at the same time, so, for example, connect the smartphone and the PC in the 2.4GHz-1 band of the first system, the 5 GHz-1 band of the second system is used exclusively for the game PC that wants to ensure speed, and allocate the 5 GHz-2 band of the third system to the repeater to expand the communication range. It can be used like this.

At present, most of the ordinary Wi-Fi 6 routers sold support the dual band of 2.4GHz band + 5 GHz band, so the use will be repeated somewhere.

For example, if you combine the game PC in the band connected to a smartphone or PC, the throughput and latency of the game environment will be reduced, or even if you combine a trunk in the band of a smartphone or PC to expand the communication range, you will run into a lack of speed this time.

Wi-Fi has recently been used in all scenarios, including smartphones, PC, and game consoles, not to mention appliances, sensors, AV devices, safety-related devices, toys, and learning materials. In order to be able to simultaneously and high-speed use of these Wi-Fi devices throughout the home, and will be added in the future, there are already many physical "lanes" of three-band compatible Wi-Fi routers is essential.
