Wi-Fi 6: Welcome to High-Efficiency Wireless

Lately, we have heard about “Wi-Fi 6”. As it sounds strange to us, the first question that comes to our minds is what happened with the standard nomenclature we were used to, like the latest, so far, 802.11ac (Wi-Fi 5). The W-Fi Alliance set a new naming standard, so the 802.11ax, also known as ‘high-efficiency wireless’ will be commonly referred to as Wi-Fi 6.

The new generation of Wi-Fi will still do the same basic thing, connect us to the internet. But, it will add a bunch of extra capabilities to make it more efficiently, saving energy and speeding up connections.

While plenty of routers are being built with a chip using a draft of a specification of 802.11ax, it won’t be officially launched till December 2019. Yet, we can find that Wi-Fi 6 will deliver improvements and new features to make the devices operate efficiently, even in dynamic environments involving a large variety of device types.

New Capabilities Wi-Fi 6 Brings

OFDMA

Uplink and downlink Orthogonal Frequency Division Multiple Access (OFDMA) will benefit users with faster network speeds, streamlined data, and network bandwidths, which connect devices more efficiently.

MU-MIMO

Multi-User Multiple Input, Multiple Output (MU-MIMO) allows us to transfer more data at one time. It also enables access points (APs) to handle larger numbers of devices simultaneously

1024-QAM

1024 Quadrature Amplitude Modulation mode (1024-QAM) increases throughput for emerging, bandwidth-intensive use cases

TWT

Target Wake Time (TWT) wake-time scheduling instead of contention-based access. A router can tell a client when to sleep and when to wake. This addition can make a considerable difference in battery life since a device will know when to listen on a channel.

WPA3

Wi-Fi 6 must use the new security protocol WPA3 that makes it harder for hackers to crack passwords by constantly guessing them. It also makes some data less useful even if hackers manage to get it. https://itpeernetwork.intel.com/fastest-wi-fi-three-things-know-about-802-11ax/#gs.3a7gum

The next WLAN standard, 802.11ax or Wi-Fi 6, is being developed to deliver considerable efficiency increases. As well, the new standard has more capacity for dense populations centers, bringing enhanced performance to users in demanding environments.

As Wi-Fi will have an immediate impact on the performance of networks in crowded places, it is expected that this new standard adopted faster than old Wi-Fi iterations. The difference is that Wi-Fi 6 can provide home users with throughput from 100Mb/s to 1Gb/s broadband connections.

Wi-Fi 6 brings the promise of real connectivity between everyone and everything anywhere. Still, we should keep in mind that the boost in multi-user support, and particularly the increase in simultaneous upstream connections in Wi-Fi 6, will help to accelerate the demand for user data. The growth cames from IoT devices and used for purposes such as machine learning, fueling artificial intelligence, the future of technology as a whole, and a growing digital economy.
