What is  Wi-Fi 6

WiFi 6(802.11ax) is designed to improve speed, increase efficiency and reduce congestion in heavy bandwidth usage scenarios

The demand for wireless access from users has shifted from a nice to have to a necessity. Due to this, network performance has become a business-critical requirement. Both workers and consumers have come to expect a reliable Wi-Fi connection – the absence of which can influence their decision to enter an establishment or to leave. In order to attract and retain customers and employees, companies need to offer reliable Wi-Fi and an amazing experience, or risk losing business. And, to accommodate the growing number of mobile and IoT devices, improvements to the efficiency of a wireless network – and how it handles congestion and ever-increasing capacity demands has become a key factor of success.

Top 6 Benefits Of Wifi 6

Wireless networks are beginning to take advantage of the new features of WPA3. It helps in providing secure wireless networking. This feature is not mandatory in previous Wifi networks, but accreditation from the Wifi Alliance mandates its usage in Wifi 6, resulting in an overall more secure setup. The user experience is the same, but with enhanced capabilities to thwart hackers, boost encryption, and, most crucially, for sites using the IoT devices.  to you.

Wifi 6 has features to effectively put specific devices’ Wifi settings to “sleep” when it’s not being used. This frees up bandwidth by sleeping connections, not in use and opening them up to other active devices. 

An environment that is more protected, interconnected, secure, and efficient must be developed across industries. One may accomplish this by leveraging the low power demands of Wifi 6 and boosting the use of tiny IoT sensors. Because these devices lack the battery capacity of larger personal devices, they rely on Wifi 6’s more efficient power requirements, which use fixed scheduled communications through Target Wake Time.TWT helps IoT and mobile devices maximize battery life by waking up infrequently to receive buffered data.

 

Increased device density often leads to a speed reduction, which is not the case with Wifi 6. When a signal is sent, a new technique known as Orthogonal Frequency Division Multiple Access (OFDMA) assists in dividing the load. That is, a single Access Point may communicate with several devices simultaneously. This is a significant benefit when one must connect several devices. This feature changes the long-established paradigm of “only one device can talk at a time,” which has defined the previous Wifi standards since their inception. 

Wifi 6 dynamically uses resource units to enable the AP to support multiple clients simultaneously using smaller channels within channels for lower-bandwidth applications. Performance is enhanced in areas with several connected devices, and consumers would have less competition for bandwidth. 

The device number for access points and network access control is not restricted to a particular workstation in today’s typical office environment. They will most likely own a desktop, a smartphone, and maybe a smart accessory. With a growing workforce, the number of sensor nodes, scanning devices, and other equipment would continue to rise.

This necessitates providing a degree of usability in which users do not experience jitter, lag, or total freezing during video and audio sessions. This is possible because of the increased access point capacity provided by the Wifi 6 standard. Wifi 6 now supports configurations up to 8×8:8 antennas, up from the previous maximum of 4×4:4 — permitting more concurrent communication, increasing speeds, and enabling several users to “speak” simultaneously. 

Wifi 6 may even direct its signal to the site of a wireless device to increase dependability and throughput. Beamforming focuses the signal in that pathway instead of distributing it uniformly across the area. This aids in improving the reliability and speed of the connection.

In terms of access points, wireless vendors are shipping both 8×8 and 4×4 products. This nomenclature refers to the number of spatial streams, which is an essential building block in the overall Wifi LAN performance. Because of size and power limitations, many smaller wireless devices will never support more than 2×2. But having a Wifi 6 router capable of 8×8 spatial streams means one can service more devices simultaneously and achieve more general efficiency. The increase in the maximum spatial stream of Wifi 6 is a factor defining overall cell performance.

Overall, Wifi 6 delivers more throughput and capacity than previous generations of Wifi. It can use 1024 quadrature amplitude modulation compared to the 256 maximum used by Wifi 5 accounts for most of the improved performance.  

Multi-User  Performance

Arguably the most important new feature in the 802.11ax standard
is an enhanced multi-user feature called OFDMA (Orthogonal
Frequency Division Multiple Access). Multiple devices with
varying bandwidth needs can be served simultaneously instead of
the existing model where devices compete with one another to send
data. With 802.11ax there is no contention as each device is
simultaneously scheduled to transmit data in parallel.
Handling data packets in this way improves performance, as a large
number of packets – especially those that are latency sensitive such
as voice traffic – can be transmitted simultaneously. In dense
environments, instead of using a single vehicle to carry traffic, it’s like
using a carpool model. Traffic is pooled into a transport allowing for
multiple conversations to happen at once. This allows access points
to handle traffic from multiple 802.11ax devices more efficiently.
