Wi-Fi technology is a fundamental blueprint that defines how wireless data is transmitted to devices such as PCs and smartphones. With each new Wi-Fi standard, the goal is to achieve faster and more efficient wireless connections. The latest standard, Wi-Fi 6 (officially known as 802.11ax), builds upon previous standards to provide faster speeds, better bandwidth, and improved stability for connected devices.

The Advantages of Wi-Fi 6

Wi-Fi 6 incorporates functions such as OFDM (Orthogonal Frequency-Division Multiplexing) and BSS Coloring to ensure that devices can transmit data without delay, even in large networks. It also introduces the 6 GHz frequency, which enables faster Wi-Fi speeds. Device manufacturers have already started offering Wi-Fi 6 devices, and the new standard is gaining traction in the market.

One of the main advantages of Wi-Fi 6 is increased bandwidth for Wi-Fi transmissions. It supports the 6 GHz frequency and can use 320 MHz channels, allowing for faster speeds and more concurrent connections. Additionally, Wi-Fi 6 improves upon previous standards by offering a wider range of radio channels, faster MIMO streams, and features that ensure efficient transmission among multiple devices.

Another important aspect of Wi-Fi 6 is its compatibility with previous standards. Existing devices in your home network will be able to connect to a new Wi-Fi 6 router, ensuring seamless integration. In many cases, Wi-Fi 6 also provides faster speeds and better performance due to improved hardware and antennas.

First Wi-Fi 6 Devices

Many manufacturers have already released Wi-Fi 6 devices, including routers, repeaters, and modules. AVM, a company based in Germany, has even skipped Wi-Fi 6E and opted for Wi-Fi 6 in their new product offerings. This shows the growing demand and anticipation for the advantages that Wi-Fi 6 brings to the table.

Who Benefits from Wi-Fi 6?

The switch to Wi-Fi 6 will be worthwhile for those who require high Wi-Fi speeds or frequently transfer large amounts of data. Gamers, content creators, and users with a large number of connected devices will benefit from the increased bandwidth and improved stability of Wi-Fi 6. Additionally, Wi-Fi 6 is essential for bringing online connections beyond the gigabit limit into home networks without restrictions.

Wi-Fi 6E and the Extended Frequency Range

Wi-Fi 6E is an extended version of Wi-Fi 6 that utilizes the 6 GHz frequency range. This frequency range offers more available channels, resulting in less interference and faster speeds. Wi-Fi 6E allows devices to use a third frequency for wireless transmission, in addition to the 2.4 GHz and 5 GHz frequencies used by previous standards. However, since there are currently few Wi-Fi products designed for this frequency, the 6 GHz connection typically runs without interference.

European users can benefit from the European solution, as no other radio technologies operate in the 6 GHz frequency range. This means that Wi-Fi 6 routers can use the 6 GHz frequency without restrictions and without the need for Dynamic Frequency Selection (DFS).

Wi-Fi 6 Speeds and Data Transfers

The speed of a Wi-Fi 6 connection depends on the number of data streams, also known as MIMO streams, between the transmitter and receiver. Wi-Fi 6 supports more MIMO streams compared to previous standards, resulting in higher theoretical transmission rates. With 16 MIMO streams and a 320 MHz channel over the 6 GHz frequency, a Wi-Fi 6 connection can achieve a theoretical transmission rate of around 46 Gbps, nearly five times faster than Wi-Fi 5.

It's important to note that achieving maximum throughput speeds may not be possible in real-world scenarios, as manufacturers typically do not develop routers with the maximum number of MIMO streams per frequency. However, Wi-Fi 6 devices still offer significant speed advantages due to wider channels and improved modulation techniques such as 4096-QAM.

Multi-Link Operation (MLO) and Simultaneous Transmissions

One of the key features introduced in Wi-Fi 6 is Multi-Link Operation (MLO), which allows devices to establish multiple links and transmit data simultaneously over several frequencies. This feature overrides the basic rule of Wi-Fi transmission, enabling faster and more stable connections. With MLO, devices can establish parallel communication over multiple frequencies, increasing overall Wi-Fi speed and reducing latency.

The use of MLO also enhances the efficiency of Wi-Fi connections by dynamically selecting the link with the least interference. This improves the reliability of data transmission, particularly in congested environments with multiple Wi-Fi devices.

Wi-Fi 6 and Battery Efficiency

Wi-Fi 6 introduces enhancements specifically targeted at devices with batteries or rechargeable batteries. The standard extends the function of Wi-Fi 6 by introducing the Target Wake Time (TWT) feature. TWT allows the router to schedule fixed transmission times with mobile devices, reducing power consumption by ensuring that devices only need to be reachable during specific time intervals.

Wi-Fi 6 further improves power efficiency with the Restricted Target Wake Time, which guarantees that the radio channel is always free for transmissions that must occur at fixed times. By designating specific clients to transmit at certain times, other devices are required to vacate the radio channel, reducing interference and optimizing power usage.

Available Wi-Fi 6 Devices

To take advantage of the numerous innovations offered by Wi-Fi 6, you will need compatible hardware, including routers, repeaters, notebooks, and smartphones. Many manufacturers have announced Wi-Fi 6 routers and mesh systems, with some already available for purchase. The selection of Wi-Fi 6 devices is expected to increase significantly by the end of 2023.

Switching to Wi-Fi 6 is particularly beneficial for users who require high Wi-Fi speeds, have a large number of connected devices, or want to cover a large area wirelessly. Wi-Fi 6 routers are also necessary for bringing internet connections beyond the gigabit limit into home networks without restrictions.

The Future of Wi-Fi

The development of Wi-Fi standards is an ongoing process, and even as Wi-Fi 6 gains widespread adoption, industry experts are already planning for the future. Future Wi-Fi standards will likely include multi-AP operation, allowing multiple routers or access points to transmit data jointly to Wi-Fi clients. This will significantly improve data transfer speeds and stability.

There is also discussion about Wi-Fi standards that support data rates of over 100 Gbps, as well as the possible use of the 60 GHz frequency with extra-large radio channels. Additionally, the 802.11bf standard, known as "Wi-Fi Sensing," is being developed to detect the presence and movement of people using Wi-Fi signals. This technology can be used in applications such as Wi-Fi-based alarm systems and smart home devices.

Wi-Fi 6 in Smartphones and Notebooks

Several high-end smartphones, such as the Samsung Galaxy S23 Ultra, Asus ROG Phone , and OnePlus 11, already feature hardware compatible with Wi-Fi 6. However, firmware updates are needed to activate Wi-Fi 6 functionality on these devices. The availability of Wi-Fi 6 smartphones is expected to increase by the end of the year.

The first notebooks with Wi-Fi 6 support are also expected to be available for purchase by the end of the year, with Intel likely to release a suitable Wi-Fi module alongside its 14th Core generation Meteor Lake processors.


Wi-Fi 6 offers significant advantages over previous Wi-Fi standards, including increased bandwidth, faster speeds, and improved stability. The availability of Wi-Fi 6 devices, such as routers, repeaters, notebooks, and smartphones, is steadily increasing, making it easier for users to transition to the new standard. Whether you require high-speed internet for gaming, content creation, or simply have a large number of connected devices, Wi-Fi 6 provides the performance and reliability needed to meet these demands.
