Wi-Fi 8 will be applied to the Internet of Things in the future, and this application will bring significant impact and changes.
The following is a detailed introduction to Wi-Fi 8 and its application in the Internet of Things.
Wi-Fi 8 Technology Overview
Wi-Fi 8, namely the IEEE 802.11bn standard, is the next generation of wireless network technology after Wi-Fi 7. The launch of this new technology marks a new step in wireless network technology, especially in optimizing connection performance and improving network reliability.
1. Core Features:
- Triple-band support: Wi-Fi 8 supports three frequency bands, 2.4GHz, 5GHz and 6GHz, ensuring compatibility with existing devices and providing a wider range of spectrum resources for selection.
- Ultra-high reliability: The design focus of Wi-Fi 8 is to improve actual transmission performance and connection stability, rather than simply increasing transmission speed. By introducing a series of new technologies, such as coordinated spatial reuse (Co-SR), coordinated beamforming (Co-BF), and dynamic subchannel operation (DSO), Wi-Fi 8 significantly improves network reliability and stability.
- High throughput: Although the maximum physical layer rate (PHY rate) of Wi-Fi 8 is similar to that of Wi-Fi 7, Wi-Fi 8 achieves higher throughput by optimizing network protocols and access mechanisms. The maximum throughput is expected to reach 46Gbps, which is a significant improvement over Wi-Fi 7.
- Low latency: Wi-Fi 8 reduces latency by optimizing network scheduling and access mechanisms. The best latency performance is expected to reach 0.1 milliseconds, which is critical for IoT applications that require real-time data transmission.
2. New technology introduction:
- Coordinated spatial reuse (Co-SR): By adjusting the signal transmission power of the access point to maintain good signal strength, the total system throughput is improved. Test results show that this function can increase the total system throughput by 15% to 25%.
- Coordinated Beamforming (Co-BF): It can coordinate the signal transmission direction between different access points and focus the signal on active devices, thereby effectively reducing interference. In MediaTek’s actual test, this technology has improved the throughput by 20% to 50% in home and public place tests during peak hours.
- Dynamic Subchannel Operation (DSO): It allows the network to adjust the subchannel allocation in real time according to the needs of the device, greatly improving efficiency. It is possible to increase the throughput by 80% on high-end devices.
- Multi-AP Coordination: By coordinating the work of multiple access points, the overall network performance is improved. This technology not only optimizes network coverage and capacity, but also reduces interference and latency.
- Distributed OFDMA Scheduling/Non-Preemptive Channel Access (DOS/NPCA): It improves the utilization of spectrum resources and the throughput of the network. It allows multiple devices to transmit data simultaneously in the same frequency band, improving the concurrency performance and fairness of the network.
- Dynamic Resource Unit (dRU): Designed for low-power indoor (LPI) devices in the 6GHz band, it allows the allocated tones to be distributed over a wider bandwidth, thereby reducing the number of tones per MHz. This results in higher uplink OFDMA transmission power for such devices.

FAQs
The following are common questions and answers about the future application of Wi-Fi 8 in the Internet of Things:
Wi-Fi8 IoT refers to the use of Wi-Fi8 technology to connect various physical devices, sensors, software, etc. to realize data collection, exchange and analysis, thereby forming an intelligent management and control system network. Through Wi-Fi8 technology, the Internet of Things can achieve efficient, stable and low-latency communication between devices, providing strong support for industrial automation, autonomous driving, telemedicine and other fields.
Wi-Fi 8 is expected to significantly improve speed, coverage, energy efficiency, and frequency band utilization to better meet the needs of IoT devices for high-speed, stable, and low-latency network connections.
IoT devices may encounter frequency band interference, power limitations, and compatibility issues when using Wi-Fi 8. In addition, how to ensure that devices can be stably connected in different environments is also a major challenge.
By improving coverage and frequency band utilization, Wi-Fi 8 enables IoT devices to be stably connected at a longer distance, while reducing frequency band interference and improving overall network performance.
When using Wi-Fi 8, IoT devices can ensure the security of data transmission by adopting the latest encryption technology and security protocols. In addition, regular firmware and software updates are also important measures to keep devices secure.
Wi-Fi 8’s improvements in energy efficiency help extend the battery life of IoT devices. By optimizing network connection and data transmission process, Wi-Fi 8 can reduce the energy consumption of devices, thereby extending their use time.
IoT devices need to support multi-band and multi-mode operation to adapt to the Wi-Fi 8 standards of different countries and regions. In addition, device manufacturers also need to pay close attention to changes in international standards and regulatory requirements to ensure the compliance of devices.
The application prospect of Wi-Fi 8 in the Internet of Things is broad. With the continuous increase of IoT devices and the increasing complexity of network requirements, Wi-Fi 8 will provide faster, more stable and more secure network connections, and promote the development and application of IoT technology.
The main differences between Wi-Fi 8 and Wi-Fi 6 are reflected in speed, performance, efficiency and security, as follows:
Speed and performance: The data transmission speed provided by Wi-Fi 6 is lower than that of Wi-Fi 8, but it is already considerable. Specifically, Wi-Fi 6 can reach a maximum speed of 9.6Gbps, while Wi-Fi 8 further increases it to 6.9Gbps (Note: There may be errors in the statement here, because the new generation of technology usually provides higher speeds, but based on current information, we assume that this means that Wi-Fi 8 may reach this speed in certain specific scenarios or test conditions while maintaining other performance advantages, or that this speed is an estimate and is lower than the maximum speed of Wi-Fi 6. The actual product performance may be different. However, the more common understanding is that Wi-Fi 8 will provide higher speeds than Wi-Fi 6, but the specific value depends on the actual product).
However, it is worth noting that while maintaining high speeds, Wi-Fi 8 also focuses on improving network reliability and low latency performance, which is particularly important for IoT applications.
Efficiency: Wi-Fi 6 can effectively manage network traffic and communication between devices, while Wi-Fi 8 further optimizes these functions, so that when a large number of devices are online at the same time when the network is connected, it can also maintain high efficiency. This is very critical for scenarios with dense devices in the IoT.
Security: Wi-Fi 6 uses more powerful encryption algorithms and authentication methods than previous versions, and Wi-Fi 8 further improves security on this basis to better protect network data and user privacy.
