What is Wi-Fi 6? All you need to know about it!

WiFi 6 has become a new buzzword! Apart from knowing that it is the sixth generation of WiFi behind the 802.11ax specification, we have little idea about this technology. So, wha,t this technology holds for us and how is it different from its previous iterations. These are some of the questions we will attempt to answer in today’s post!

What is Wi-Fi 6

Wi-Fi 6 is a new labeling convention developed by Wi-Fi Alliance, which is a non-profit organization that promotes Wi-Fi technology and certifies Wi-Fi products in compliance with certain standards of interoperability. The new labeling is considered as the faster version of Wi-Fi technology we have been using for more than a decade now.

The organization came up with the convention since the earlier names were difficult to recall (real name being 802.11ax). The Wi-Fi currently in use, 802.11ac, is also known as Wi-Fi 5 and supports a speed of up to 3.5 Gbps. Wi-Fi 6 will support 9.6 Gbps, more than double the 3.5 Gbps you get with Wi-Fi 5.

Having said that, let us further explore:

1. Differences between Wi-Fi 4, Wi-Fi 5 and Wi-Fi 6 technology
2. Why do we need Wi-Fi 6
3. Key benefits of Wi-Fi 6 technology
4. How Wi-Fi 6 technology will work?

2] Why Wi-Fi 6

The ubiquity of Wi-Fi and its ability to complement other wireless technologies like Artificial Intelligence is slowly translating the vision of connecting everyone and everything into reality. At the same time, the popularity of Wi-Fi has created very diverse and densely populated Wi-Fi conditions. This calls for new technological advances to meet the needs of users. Wi-Fi 6 believes, it has answers to this as it will possess the capability to enable Wi-Fi devices to operate efficiently in the most dense and dynamic connectivity settings.

Apart from robust connectivity and speed, users demand stable performance in most demanding Wi-Fi environments. Wi-Fi 6 promises to deliver this, alongside other benefits.

3] Key benefits of Wi-Fi 6 technology

• High performance in environments having many devices connected.
• Increased capacity
• Higher data transfer rates
• Improved power efficiency

In addition to the above, devices certified by this technology a.k.a. Wi-Fi CERTIFIED 6 devices will meet the highest standards for security and interoperability. Besides, they’ll also enable lower battery consumption, making it a preferred choice for the Internet of Things (IoT) and emerging applications like,

• Virtual and augmented reality used in e-Learning
• Healthcare
• Telepresence

The reason why Wi-Fi 6 is considered as the idle choice for the development of the Internet of Things is that it supports the TWT (Target Wakeup Time) technology. The technology enables devices to determine the number of times they can be allowed to send or receive data which in turn allows 802.11ax (WiFi 6) access points to effectively increase device sleep time and significantly conserve battery life. This idea remains a core feature in the development of IoT. In addition to this, Target Wake Time enables wireless access points and devices to negotiate and define specific times to access the medium. This optimizes spectral efficiency by manifolds and reduces contention and overlap between users.

4] How Wi-Fi 6 technology works?

Wi-Fi 6 mainly uses two technologies – MU-MIMO and OFDMA.

• MU-MIMO – stands for ‘multi-user, multiple-input, multiple-output’. It is supported by routers and endpoint devices. The technology is used to increase the number of antennas on a wireless router that is used for both receiving and transmitting, improving capacity for wireless connections.
• OFDMA –  It stands for ‘orthogonal frequency division multiple access’ and as the name suggests, the technology allows single AP connect simultaneously to multiple clients with varying bandwidth requirements.

Already, we are experiencing a demand for increased capacity and throughput speeds. This will continue to grow further as users will keep adding more wireless devices to each network and expect faster response times for their activities (streaming favorite videos or downloading large files) As such, moving to WiFi 6 or 802.11ax technology that promises to meet all our demands will seem as the most viable option.
