This changes with the new WLAN standard Wi-Fi 6
The new Wi-Fi standard IEEE 802.11ax is in the starting blocks. Technical improvements are introduced and cryptic designations are finally abolished.

For years, Wi-Fi standards have been revised and improved. Data throughput is increasing, connections are stabilising and interference from other devices is decreasing. These Wi-Fi standards go by the name IEEE 802.11, followed by an abbreviation. The current WLAN standard is called 802.11ac and will soon be replaced by 802.11ax.

What will change with the new Wi-Fi 6 WLAN standard?
What Wi-Fi 6 can do
As with any new WLAN standard, the focus is on the speed and reliability of the connection. Wi-Fi 5 was already adopted in December 2013; at that time, video streams in 4K were still dreams of the future and 50 GB games were purchased exclusively on shimmering discs. Today, such data volumes are considered normal and should be able to be handled by any modern household.

Wi-Fi 6 will widen technical bottlenecks and be up to 30 per cent faster. In the 5 GHz network, up to 1200 Mbit per second and antenna can be transmitted. In the 2.4 GHz network, 287 Mbit per second are possible. In flats and single-family homes, 5-GHz networks are usually not a challenge, so a router with four antennas can transmit 600 MB per second wirelessly under the best conditions.
At first glance, the question of sense may arise, because hardly any private internet connection can manage 600 MB per second. However, internal networking also benefits when data is copied from the notebook to the network storage (NAS) or several people access the network at the same time. Wi-Fi 6 also increases the range. In addition, one router serves more devices at the same time - this is just as important for hotels as for shopping centres, schools or companies.
Available devices
End devices that support Wi-Fi 6 should make their debut across the board this year. Existing devices will remain compatible. In any case, a new router that supports 802.11ax or Wi-Fi 6, such as the Netgear RAX80 Nighthawk, is required for use.
Wi-Fi 6 will take smartphones by storm and will be standard in better devices next year at the latest, such as the Samsung Galaxy S10, which already understands it today. It will still be a few years before the entire device fleet is sworn in to Wi-Fi 6. That shouldn't stop you from looking out for it in new hardware. ....
