On July 25, Qualcomm stated in its latest blog post that the goal of Wi-Fi 8 is to "prioritize reliable performance in challenging real-world environments, enhancing connectivity even in crowded, interference-prone, and mobile settings." One of the standout features of Wi-Fi 8 is "seamless roaming." This capability enables devices to achieve a "connect once, always online" experience. When devices are in motion, they can maintain continuous low-latency connections without interruptions or packet loss due to switching. A key strength of Wi-Fi 8 is its ability to deliver consistently reliable and high-quality connections even under less-than-ideal signal conditions. For instance, in certain areas, signals may weaken due to distance from the Wi-Fi source, interference, or power limitations. Qualcomm explained that Wi-Fi 8 employs a suite of physical-layer enhancement technologies that work together to sustain Wi-Fi connectivity even in imperfect environments. This is referred to as edge reliability coverage. Have you ever encountered Wi-Fi connectivity issues in high-density areas like corporate campuses, apartment buildings, or public spaces? Signal overlap or multiple devices competing for shared wireless signals can degrade the user experience. Wi-Fi 8 addresses this problem with one of its most important features—multi-access point (AP) coordination. This feature allows access points to collaborate rather than operate independently. When access points work in isolation, devices may "attach" to distant access points with weaker signals, leading to poor performance. With Wi-Fi 8, access points share resources, delivering a more consistent experience for users. Modern devices are equipped with multiple radios (Wi-Fi, Bluetooth, UWB), posing coexistence challenges. Wi-Fi 8 improves in-device coexistence performance, ensuring smoother operation when multiple radios share antennas or spectrum. This enables wireless networking technologies to gracefully handle temporary interruptions when antennas are used for other technologies. Wi-Fi 8 features enhanced in-device coexistence performance, ensuring smoother operation when multiple radios share antennas or spectrum. It also includes new features to make wireless connections more energy-efficient without sacrificing responsiveness. Notably, all the Wi-Fi 8 features mentioned by Qualcomm focus on improving reliability, with no mention of boosting Wi-Fi speeds.   Qualcomm stated that Wi-Fi 8 will have the greatest impact in smart factories, hospitals, university campuses, homes, and public spaces such as airports, stadiums, and transportation hubs. The IEEE 802.11bn standard, expected to be finalized by 2028, will serve as the foundation for Wi-Fi 8. It will support two major trends: The first trend is the shift toward personal devices like smart glasses, next-generation wearables, and health monitors. These devices require seamless short-range wireless performance to offload intensive tasks to companion devices. The second trend is the move toward AI-driven systems that need "reliable, low-latency connectivity to access edge or cloud-based AI for real-time inference." Again, Wi-Fi 8 will focus on enhancing reliability, not speed. Qogrisys Technology specializes in wireless connectivity and has released Qualcomm's next-generation Wi-Fi modules, including the WiFi 6E modules O2066PM/O2066PB and the WiFi 7 module O7851PM. These modules deliver high-efficiency data throughput in high-density environments, supporting stable performance with concurrent multi-device connections, and provide robust connectivity for corporate campuses and smart factories. Additionally, with support for the 6GHz band, they effectively avoid interference, demonstrating excellent anti-interference capabilities for smart home device connectivity and immersive experiences in public spaces. Their optimized in-device coexistence mechanism aligns with the collaborative philosophy of Wi-Fi 8.

  With the rapid development of technology, wireless networks have become an indispensable part of our daily lives. From the initial WIFI to the current WIFI 7, wireless network technology has constantly broken through, providing users with faster and more stable network experiences. This article will explore the impact of WIFI 7's MLO (Multi-Link Operation) technology on wireless networks.   What is WIFI 7 and its MLO (Multi-Link Operation) technology?   WIFI 7 (IEEE 802.11be) is the latest generation of wireless network standards, expected to gradually gain popularity in the coming years. Compared to previous generations of WIFI technology, WIFI 7 has significantly improved in terms of speed, latency, and performance. MLO technology is a key feature of WIFI 7, allowing devices to connect to multiple frequency bands (such as 2.4GHz, 5GHz, and 6GHz) simultaneously and perform parallel transmissions. This means that on the same network, devices can utilize the bandwidth of multiple frequency bands at the same time, achieving higher speeds and efficiency.     The background of dual-band integration technology   In traditional dual-band routers, the 2.4GHz and 5GHz frequency bands are usually separated, and users need to manually select or let the router automatically switch. However, with the increase in the number of devices and network load, a single frequency band may not be able to meet the needs of all devices. Dual-band integration technology combines the 2.4GHz and 5GHz frequency bands into one network, intelligently assigning devices to connect to different frequency bands, thereby reducing interference and improving speed and stability.   However, in earlier WIFI standards (such as WIFI 4, WIFI 5, WIFI 6), dual-band integration technology was not perfect, and it could only aggregate the throughput of WIFI on two or more different frequency bands through upper-layer application aggregation, which greatly increased the difficulty and stability of development.   How does WIFI 7's MLO technology improve dual-band integration?   MLO technology controls the entire process of data aggregation and disassembly at the link layer, making it imperceptible to the upper layers, allowing devices to connect to multiple frequency bands simultaneously and perform parallel transmissions. This fully utilizes the bandwidth resources of all frequency bands, improving overall network performance. In the dual-band integration mode, devices can simultaneously use signals from the 2.4GHz, 5GHz, and 6GHz frequency bands, achieving higher speeds and greater bandwidth. MLO technology can also intelligently allocate frequency band resources based on the device's location and network load, ensuring that devices are always connected to the best wireless network.   The specific improvements of MLO technology include: Parallel Transmission: MLO allows devices to utilize multiple frequency bands for data transmission simultaneously, significantly enhancing transmission speed and efficiency. Load Balancing: Through intelligent scheduling, MLO technology can distribute traffic to different frequency bands based on real-time network conditions, reducing congestion and improving network stability. Seamless Switching: Devices can seamlessly switch between different frequency bands, avoiding connection interruptions and speed losses, enhancing user experience. Reduced Network Latency: Through parallel transmission and intelligent scheduling, MLO technology reduces waiting time for data transmission, improving response speed.     Taking the newly developed WIFI7 network card module O7851PM from QOGRISYS as an example, with the support of MLO technology, the O7851PM module can achieve intelligent scheduling and load balancing across multiple frequency bands (2.4GHz/5GHz/6GHz), ensuring efficient utilization of network resources. Through intelligent scheduling, the module can distribute traffic to different frequency bands based on the device's location and real-time network load conditions, reducing network congestion and improving connection stability. The seamless switching capability of MLO technology also ensures that devices do not experience connection interruptions or speed losses when switching between different frequency bands, providing a smoother user experience.   In addition, this module also supports WIFI 7 technologies such as 320MHz bandwidth, 4096-QAM, Multi-RU, enhanced MU-MIMO, and multi-AP coordination, significantly enhancing the network performance and user experience of the module.     Conclusion   The introduction of MLO technology marks another significant breakthrough in wireless network technology. Through dual-band integration and parallel transmission, WIFI7 can provide higher speeds, lower latency, and more stable network connections, meeting the ever-increasing network demands of the future. With the gradual popularization of WiFi7, users will be able to enjoy a superior wireless network experience, driving the further development of various industries.

MESH networking, on the other hand, is a network topology that connects multiple nodes (Access Points, APs) to form a mesh network, offering seamless wireless coverage.     The working principle of MESH networking   In a WIFI 6E MESH network, multiple Access Points (APs) connect to each other through the 6GHz band, forming a dynamic mesh network. These APs not only provide conventional wireless access functionality, but also extend network coverage and enhance network stability through their interconnections. When one node needs to send data to another node, the data can be transmitted through multiple hops via multiple intermediate nodes, ultimately reaching the destination node. This approach ensures that the network can maintain connectivity through other nodes even when a node fails.   Advantages of MESH Networking   High Bandwidth: Utilizing the 6GHz band, WIFI 6E MESH networking can provide higher throughput to meet high data transmission demands.

These technical characteristics make the O2066PM module have broad application prospects in areas such as remote diagnosis, industrial internet, tablets, set-top boxes, smart robots, and more. With its high performance and reliability, the O2066PM module can provide more powerful wireless network solutions for various application scenarios.      

With the rapid development of multiple industries such as smart cars, smart terminals, smart homes, and smart manufacturing, various application fields have posed common requirements for wireless short-range communication technology in terms of low latency, high reliability, and low power consumption. The inherent limitations and technical potential of existing mainstream wireless short-range communication technologies cannot meet the technical requirements of new applications. In response to addressing the industry's technical pain points, the new generation of wireless short-range communication technology, StarFlash, has emerged. Essentially a new generation of wireless short-range communication technology, StarFlash offers six major advantages over traditional wireless short-range communication technologies: low latency, high speed, interference resistance, high reliability, high concurrency, and precise positioning.     The StarFlash technology aligns with the industrial development trends of various application fields, encompassing four typical areas: smart cars, smart homes, smart terminals, and smart manufacturing. This article primarily explains the application of StarFlash technology in the field of smart cars: 1.In-Car Wireless Active Noise Cancellation: By measuring the noise waveform entering the ear and generating sound waves of the same amplitude but opposite phase to neutralize the noise. Compared to wired noise cancellation systems, StarFlash's wireless solution reduces equipment weight and installation costs and is not restricted by wire harness layout. 2.Wireless Car Keys: Enabling keyless entry and one-button start by locating the key to intelligently unlock, lock, and start the car. StarFlash technology enhances the user experience of keyless entry systems and addresses the deficiencies of existing solutions. 3.In-Car Hands-Free Calling and Entertainment Systems: Utilizing in-car microphones to capture voice signals, which are then processed and played through speakers to enable voice communication. Current wireless short-range technologies have limited latency, anti-interference capabilities, and concurrency capabilities. StarFlash technology allows in-car communication terminals to connect with multiple phones simultaneously, enabling multiple phones to use the car's speakers and microphones for calls, reducing overall vehicle cost and weight. 4.Wireless Battery Management System (BMS): Managing and monitoring the power battery, which requires communication support between the master control and multiple slave controls, the entire vehicle, and the charger. Compared to CAN and daisy-chain communication solutions, the wireless BMS based on StarFlash technology simplifies system structure, improves the energy density of the battery pack, and enhances the reliability, accuracy, and safety of cell management. It addresses the reliability issues of long-term use of wire harnesses and connectors, reduces after-sales maintenance, eliminates high-voltage risks, and offers strong scalability with low power consumption.     The widespread application of StarFlash technology is driving transformation in the field of smart cars. StarFlash technology not only enhances the efficiency of in-car wireless active noise cancellation systems, reducing equipment weight and installation costs, but also improves the user experience of wireless car key systems and in-car hands-free calling and entertainment systems, addressing multiple deficiencies of existing solutions. Additionally, in wireless battery management systems, StarFlash technology demonstrates its strong technical advantages and potential by simplifying system structure and enhancing the reliability and safety of battery management.     From the widespread application of StarFlash technology in the field of smart cars, we can see that 2024 will be a breakthrough year for StarFlash technology.
