Which Wi-Fi6 features are mandatory?

Wi-Fi 6, also known as 802.11ax, is the latest generation of Wi-Fi technology that offers faster speeds, improved capacity, and better performance in congested areas. It brings several new features and enhancements compared to its predecessor, Wi-Fi 5 (802.11ac). In this article, we will discuss the mandatory features of Wi-Fi 6 that you should look for when purchasing a new router or device.

1. OFDMA (Orthogonal Frequency Division Multiple Access)

OFDMA is a key feature of Wi-Fi 6 that allows multiple devices to communicate with the router simultaneously. It divides the available bandwidth into smaller sub-channels, called resource units (RUs), which can be allocated to different devices. This improves the overall efficiency and capacity of the network, especially in crowded environments where many devices are connected.

2. MU-MIMO (Multi-User Multiple Input Multiple Output)

MU-MIMO was introduced in Wi-Fi 5 but has been further enhanced in Wi-Fi 6. It enables the router to communicate with multiple devices simultaneously, both downstream (from the router to the devices) and upstream (from the devices to the router). This is particularly useful in households or offices with multiple devices connected to the network, as it reduces latency and improves overall network performance.

3. Target Wake Time (TWT)

TWT is a power-saving feature in Wi-Fi 6 that allows devices to schedule their wake-up time to communicate with the router. It enables devices to enter a sleep state when not actively transmitting or receiving data, conserving battery life. With TWT, devices can coordinate with the router to determine specific time slots for communication, reducing unnecessary wake-ups and improving power efficiency.

4. 1024-QAM (Quadrature Amplitude Modulation)

1024-QAM is an advanced modulation technique used in Wi-Fi 6 to increase the data transmission rates. Compared to Wi-Fi 5's 256-QAM, it can transmit more data in the same amount of spectrum, resulting in higher throughput and improved network performance. However, it is important to note that both the router and the device need to support 1024-QAM to take full advantage of this feature.

5. BSS Coloring

BSS (Basic Service Set) Coloring is a feature in Wi-Fi 6 that helps reduce interference and improve network efficiency. In crowded environments where multiple Wi-Fi networks overlap, BSS Coloring allows devices to differentiate between signals from different networks. This reduces co-channel interference and enables devices to make better decisions about which network to connect to, resulting in improved overall performance.

6. WPA3 (Wi-Fi Protected Access 3)

While not exclusive to Wi-Fi 6, WPA3 is the latest security protocol for Wi-Fi networks and is highly recommended for any new router or device. It provides stronger encryption and better protection against common security threats compared to its predecessor, WPA2. WPA3 ensures that your Wi-Fi network is more secure and less susceptible to unauthorized access.

When purchasing a new router or device, it is important to check if these mandatory Wi-Fi 6 features are supported. While some devices may offer Wi-Fi 6 compatibility, they may not support all the features mentioned above. To fully experience the benefits of Wi-Fi 6, it is recommended to choose devices that support all these features.
