What is 802.11, 802.11ax, Wi-Fi 6, And Wi-Fi 6E?

User’s need for wireless access has changed from being a luxury to a need. The demand for bandwidth is increasing at an exponential rate. Network performance is now crucial for both consumers and businesses as a result of this. Everyone now expects a fast and dependable Wi-Fi 6 connection.

In a relatively short period of time, technology has advanced significantly. The current networks are overworked due to the exponential rise in the demand for remote work, as well as the different kinds of usage and traffic they must handle. This means that wireless standards must also adapt. The largest network problem, aside from bandwidth, is latency. As the network attempts to keep up with traffic, latency is the lag in the connection. This negatively impacts all live events, including voice, video conferencing, gaming, and Internet of Things traffic.

It was compulsory to create wireless networks that could handle the promising bandwidth-hungry traffic more appropriately in order to help reduce latency. In 2018, a new standard known as 802.11ax was created. It is presently familiar as Wi-Fi 6 by the Wi-Fi Confederation. Improving access points’ ability to manage numerous devices efficiently was one of Wi-Fi 6’s primary goals.

A Wi-Fi network’s speed is no longer its metric. The network’s ability to manage numerous clients concurrently without experiencing terrible latency problems is now at issue. Now, we can think of it as having a wider bandwidth rather than a faster rate of data movement. Virtually, several network connections serve simultaneously, instead of depending on a single connection to handle all data transfer at maximum speed.

Wi-Fi 6 (802.11ax) provides a more extended solution for handling numerous network connections and transferring exhaustive volumes of data.

What is Wi-Fi 6?

The most current Wi-Fi Alliance excellence, Wi-Fi 6, is based on the 802.11ax protocol and offers compulsory features expected for next-generation business needs.

Wi-Fi 6E: The Future

Access to the unaccustomed 6 GHz frequency band is made possible by Wi-Fi 6E, which also holds unreliable new potential for wireless networking.

By improving on today’s Wi-Fi capabilities, these newer protocols are essentially giving our current Wi-Fi a turbo feature. They will be utilized in 5G support as well as AI and IoT technologies. Time-sensitive applications should virtually completely eliminate latency with Wi-Fi 6.

2.4 GHz, 5.9 GHz, and 6 GHz: Fast Forward to the Future

Since 2point, 4 GHz, and 5 GHz are beforehand providing ultra-low suspension and fast multi-gigabyte speeds, why does the FCC need to open these frequencies? There were 7.6 billion appendant devices in 2019. Over 25 billion appended devices are expected to be sold worldwide by 2030. These agglutinate devices are required to originate over 150 zettabytes (ZB) of data, which is coordinated to 150 trillion gigabytes.

Wi-Fi 6, 5G, C-V2X, Bluetooth 5, Zigbee, Z-Wave, and promiscuous other wireless protocols under development today would all be used to concatenate these wireless devices. According to growth projections, the FCC has concluded that by 2025, it will have to permit unlicensed use of mid-band spectrum up to 1 GHz.

The bandwidth of the 2 GHz and 5 GHz bands is 100 MHz and 665 MHz, respectively. Opening the 5 GHz and 9 GHz bands will increase bandwidth by 45 MHz, but the new 6 GHz band will offer up to 1,200 MHz. Almost everything will be able to be wireless once these extra bandwidths are made available. For example, autonomous vehicle communications will be possible.

What makes Wi-Fi 6 work?

To support dozens of high bandwidth connections cumulatively, the Wi-Fi 6 standard makes utilization of new wireless technology developments like OFDMA, MU-MIMO, and TWT.

Wi-Fi 6 addresses the largest challenges for all Wi-Fi networks: The variation of applications and the growing number of devices. By increasing bandwidth throughput up to four times over the previous 802.11ac standard, 802.11ax addresses these issues. Using both the 2.4 GHz and 5 GHz bandwidths to control traffic is one of the other enhancements of Wi-Fi 6. However, OFDMA (Orthogonal Frequency Division Multiple Access), a multi-user performance feature, is the 802.11ax’s greatest improvement. This enables the simultaneous connection and use of the network by numerous devices with various bandwidth requirements. When devices had to queue up and compete with one another to send and receive data, this was an improvement over earlier wireless standards. Since every device can simultaneously send and receive data independently, there is no competition when accessing over an 802.11ax network. Large volumes of data can be handled by the network by using the 802.11ax protocol to manage the available bandwidth. Voice and video are examples of latency-sensitive applications that can be handled concurrently.

Another protocol, Time Multi-User Multiple Input/Multiple Output (MU MIMO), which was first introduced in 802.11ac, is designed to manage high traffic from multiple devices. It can now support up to eight devices transmitting and receiving simultaneously using a dedicated channel per device after being upgraded for use with 802.11ax. Low bandwidth data from IoT devices and voice data would be better handled by OFDMA, but MU MIMO has the added advantage of supporting large amounts of data, such as streaming HD video.

Target Wake Time (TWT), a scheduling scheme negotiated with the access points, is another advantage of the Wi-Fi 6 protocol. It allows devices to stay idle until it is their turn to send data. The extended battery life of smartphones, tablets, and Internet of Things devices is an inherent advantage of their ability to enter an inactive mode. Given that TWT has an operating mode for low-power, low-bandwidth devices like sensors, industrial automation, and medical devices, the Internet of Things gains a lot from it. Devices will be divided into 2GHz, 4GHz, or 5GHz bands by the 802.11ax access point according to their data needs.

The 802.11ax’s efficiency improvements are evidently perceived as a faster network and better access for every client connected to the network. Wi-Fi networks’ capacity to manage significantly more traffic, such as voice and video streaming in high-density settings, is significantly increased by the 802.11ax protocol. Since 802.11ax makes better use of the 2.4 GHz, 5 GHz, and 6 GHz Wi-Fi spectrums, its release coincides with the ideal moment.
