Wi-Fi 6

Wi-Fi 6 is the sixth generation of the wireless LAN standard. Its official name is IEEE 802.11ax. It sends more data in the same frequency band than the older Wi-Fi 5 by sharing the channel in a new way. So it is designed to slow down less when many devices use the internet at the same time.

This standard came about to reduce the crowding that happened in spaces with many devices, such as homes and offices. As phones, laptops and home appliances multiplied, wireless signals began to collide more often. So Wi-Fi 6 developed in the direction of raising power efficiency and the performance of many simultaneous connections together.

Wi-Fi 6 divides one channel into several small pieces and shares them out. Many devices can send and receive at once, each using only the piece it needs, so the waste of every device waiting for its turn is reduced.

It also improves the ability to send signals to several devices at the same time. The antennas split the signal and send it in several directions, so the wireless space is used more efficiently.

It suits homes and offices where many smart appliances, cameras and laptops are connected. You get the full effect only when both the router and the devices support Wi-Fi 6.

You can also expect more stable connections in places where many people gather at once, such as public spaces and concert halls. But if your internet line is slow, changing the wireless standard will not change the speed you feel very much.

It is easy to think that something called Wi-Fi 6 is always fast. Actual speed depends a lot on the performance of the router, the material of the walls, the distance and the speed of the internet line.

Older devices may not be able to use Wi-Fi 6 features. It is a good idea to check that the device and the router support the same generation. If you buy by the label alone, the result may not match what you expected.

Picture a restaurant at lunchtime where many people at the tables are placing orders. If the line of orders is split up and handled all at once, the waiting gets shorter. Wi-Fi 6 gets a similar effect by splitting up and carrying the data of many devices together.

Knowing about Wi-Fi 6 makes it easier to compare the supported standards in the descriptions of wireless internet products. Even with the same speed label, how many devices can use the network reliably at the same time depends on the standard.
