Multi-RUs: The Key to Superior Wi-Fi 7 Performance

Modern homes are packed with internet-connected devices, all vying for a strong signal from your wireless access points. From smartphones and PCs to gaming consoles, smart TVs, tablets, and smart home gadgets, each relies on a stable internet connection to deliver the experiences you expect. Therefore, your access points must be capable of communicating with all of them effortlessly. Wi-Fi 7 brings in new technologies to enhance bandwidth, minimize latency, and more effectively handle numerous connected devices. One of these innovations is Multi-RU Puncturing. In this article, we will cover the key concepts of Multi-RUs puncturing: RUs, puncturing, and Multi-RUs, and how these components come together to enhance your networking experience.

What is RU?

Resource Units (RUs) are composed of multiple small segments of wireless radio frequency, with each RU consisting of a certain number of tones. It is a fundamental concept in Wi-Fi technology that is critical in optimizing network performance. In the context of Wi-Fi 6 and Wi-Fi 7, RU refers to how the available spectrum is divided into smaller sub-channels or units. These sub-channels are then allocated to different devices, allowing multiple users to transmit data simultaneously over the same frequency band. By efficiently utilizing the available spectrum, RU helps reduce latency, improve throughput, and enhance overall network efficiency.

Multi-RUs of Wi-Fi 7

Wi-Fi 7, the latest evolution in wireless technology, takes the concept of Resource Units introduced in Wi-Fi 6 to a new level with Multi-RUs. While OFDMA was a key component in enhancing networking experiences with Wi-Fi 6, there was still room for improvement. In Wi-Fi 6 access points, a single user could only utilize one RU at a time, often leaving other RUs underutilized.

Multi-RUs addresses this inefficiency by allowing a single device to leverage multiple RUs simultaneously, whether across different frequency bands or within the same band. This advanced feature not only boosts the efficiency of bandwidth usage but also significantly increases the amount of data that an individual user can download and upload. As a result, Wi-Fi 7 achieves higher data rates, reduced latency, and improved performance in high-density environments. This makes Multi-RUs particularly beneficial for applications that demand large amounts of data, such as 4K/8K streaming, virtual reality (VR), and augmented reality (AR).

Overcoming Interference with Puncturing

Interference is a major factor that can lead to an unstable wireless connection. Various elements, such as the presence of multiple wireless networks in the same area, can cause this interference. Wi-Fi protocols require data transmissions to utilize wireless channels continuously, which are categorized as primary and secondary channels. However, when a secondary channel conflicts with a radar system or is restricted by regional regulations, the network's bandwidth may be limited to just the primary channel. Puncturing offers a solution by enabling routers to optimize the use of available Wi-Fi channels. This technique allows the slicing or bonding of 80 MHz and 160 MHz Wi-Fi channels into 20 MHz increments. While the primary channel remains intact, puncturing helps to alleviate congestion caused by interference, maintaining transmission speeds and preventing signal drops in multi-user environments.

Multi-RUs Puncturing: Combining Technologies for Optimal Performance

Individually, Multi-RUs and puncturing are highly effective in mitigating channel interference and delivering high transmission speeds to numerous users. When combined, they create a powerful synergy. For example, consider an 80 MHz channel with three available 20 MHz subchannels, totaling 60 MHz. A Wi-Fi 7 access point can dynamically split or combine these subchannels based on traffic demands. In this scenario, User #1 can utilize two 20 MHz channels, rather than being restricted to just one, while User #2 maintains a stable connection despite interference.

Additionally, Wi-Fi 7's multi-link operation (MLO) plays a crucial role by allowing devices to transmit and receive across multiple bands and channels simultaneously, with separate data and control planes. This parallel processing boosts speeds by aggregating bandwidth and ensures more reliable Wi-Fi connections across multiple bands used concurrently.
