WiFi7-11.be -IPQ9574/IPQ9554-QCN9274-QCN6274-More RU sizes and locations for OFDMA tone plan (Multi-RU) technology
WiFi7 has now slowly entered the market. Many wireless companies are purchasing it and just testing its functions first. It will take some time to enter the large-scale market.
Many technologies of WiFi7 will be improved, whether it is throughput, transmission speed, bandwidth, etc., they are all much higher than WiFi6.
Key benefits of Wi-Fi 7 technology include:
? Extension of 11ax to 240 MHz and 320 MHz
? More RU sizes and locations for OFDMA tone plan (Multi-RU)
? Punctured transmissions
? 4k-QAM
?Multi-Link Operation
?320/240MHz and Multi-RU
?Power save improvements
?Co-ordinated AP
Let’s take a closer look at the detailed introduction of More RU sizes and locations for OFDMA tone plan (Multi-RU) technology:
OFDMA (Orthogonal Frequency Division Multiple Access) is a technology used in Wi-Fi 6 and Wi-Fi 6E routers to improve the efficiency and performance of wireless communication. In the context of Wi-Fi routers, OFDMA tone planning refers to how the available frequency spectrum is divided into subcarriers or tones for transmitting data. The RU sizes and locations are key parameters in this process. Let's break down their roles:
RU Sizes (Resource Unit Sizes): RU sizes determine the number of subcarriers or tones allocated to a specific device or user. Different RU sizes can be allocated to different devices simultaneously, allowing for more efficient use of the available spectrum. Here are some common RU sizes:
26-tone RU: This is typically used for low-data-rate devices and provides narrow bandwidth.
52-tone RU: Offers a moderate bandwidth and is suitable for devices with moderate data needs.
106-tone RU: Provides a wider bandwidth and is suitable for devices that require higher data rates.
The choice of RU size depends on the specific device's requirements and the network conditions.
Locations: OFDMA also allows for the allocation of specific subcarrier locations within the channel. This is important for minimizing interference and optimizing the use of available spectrum. By strategically selecting the subcarrier locations, it's possible to reduce co-channel interference and ensure efficient data transmission.
The primary role of RU sizes and subcarrier locations in OFDMA tone planning within a Wi-Fi router is to:
Optimize Spectrum Utilization: By selecting the appropriate RU sizes and subcarrier locations, the router can efficiently allocate available spectrum to devices based on their data needs. This helps in reducing wasted bandwidth and improving overall network capacity.
Minimize Interference: Careful selection of subcarrier locations can minimize interference between devices, allowing multiple devices to communicate simultaneously without causing excessive signal overlap.
Enhance Network Performance: The ability to tailor the RU sizes and subcarrier locations based on the needs of connected devices leads to improved network performance, lower latency, and better user experiences, especially in crowded Wi-Fi environments.
Support Multiple Devices: OFDMA enables a single channel to serve multiple devices with varying bandwidth requirements simultaneously, which is essential for accommodating the growing number of IoT devices and high-bandwidth applications.
Overall, RU sizes and subcarrier location planning in OFDMA help Wi-Fi routers deliver higher throughput, reduced latency, and improved network efficiency, making them suitable for modern wireless communication demands.
