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.

As I pondered over this headline before starting, I couldn't shake off my concerns about whether it aligns with the content. Having worked in the WiFi industry for 10 years, I've been deeply troubled by the development of domestic WiFi chips two years ago. Back then, domestic digital transmission WiFi chips were mostly confined to the low-end market, with little visibility in the high-end market. Here, I'm compiling a summary. If there are any inappropriate parts, let's just overlook them as a joke.   WiFi chips are roughly divided into digital transmission WiFi and IoT WiFi. Apart from smartphones, hardware is primarily utilized in the form of modules.   Domestic IoT WiFi boasts high cost-effectiveness, with significant advantages closely tied to its characteristics. IoT WiFi is characterized by small data and control applications, featuring a built-in RTOS system that facilitates application development. It is primarily used in smart home and control scenarios, with devices like the ESP8266 serving as typical representatives. On the other hand, digital transmission WiFi is characterized by large data transmission, spanning various applications such as audiovisual and big data scenarios, which demand higher throughput, low latency, multiple connections, and stability. Consequently, chip design for digital transmission WiFi modules is more challenging. Today, we will mainly focus on the development of digital transmission WiFi modules.     Two years ago, WiFi technology had advanced to WiFi 6, while domestic digital transmission WiFi chips were mostly single-antenna 2.4GHz, still adhering to the WiFi 4 standard. Without exception, they were unable to break through to higher specifications due to issues like IP licensing restrictions and unassailable patents. At that time, WiFi 5 and WiFi 6 chips primarily came from Taiwanese and Western manufacturers, leading to fierce competition between domestic and Taiwanese companies for low-end WiFi 4 modules, resulting in intense price competition. Meanwhile, Taiwanese and Western companies dominated the mid-to-high-end WiFi 5/6 module market, reaping profits from niche markets. We could only sigh with frustration at our inability to compete on a global scale.     The year 2023 could be considered the dawn of true development for domestic WiFi chips. Domestic WiFi chips leaped directly from WiFi 5 to WiFi 6, ushering in a wave of new domestic WiFi chip players in the market. For instance, AIC's AIC8800 swiftly captured the market with its cost-effectiveness by initially focusing on 2.4GHz WiFi 6, then rapidly iterating to dual-band WiFi 6 to further consolidate its position. Amlogic's WiFi 6, coupled with its SOC, also gained recognition in the market. Meanwhile, WUQI, leveraging its technological edge and benchmarking against leading industry players, led the charge with its flagship WQ9101, guiding domestic WiFi chips towards greater heights with its technological advancement.     In 2024, there will be a plethora of domestically produced WiFi 6 chips and modules entering the market. Due to varying levels of technological prowess among chip manufacturers, there will be a prevalence of low-end offerings, resulting in significant homogeneity and inconsistent chip performance, primarily relying on cost-effectiveness to penetrate the market. Stronger players in the industry will pursue independent research and development, positioning themselves at the forefront of technology compared to their counterparts.     Parameters of domestically produced WiFi 6 chip modules: Low-end domestic WiFi 6 chip module parameters: 1.2.4GHz single frequency 2.b/g/n/ax 3.1T1R single antenna 4.DBAC   Mid-range domestic WiFi 6 chip module parameters: 1.Dual-band 2.4/5.8GHz 2.a/b/g/n/ac/ax 3.1T1R single antenna 4.DBAC   High-end domestic WiFi 6 chip module parameters: 1.Dual-band 2.4/5.8GHz 2.a/b/g/n/ac/ax 3.1T1R single antenna or 2T2R dual antenna 4.DBAC+DBDC Among high-end domestic WiFi 6 chips, the WQ9101 chip demonstrates advanced features compared to similar domestic counterparts. Based on RISC-V design, its main parameters are as follows: 1.Dual-band 2.4/5.8GHz 2.a/b/g/n/ac/ax 3.1T1R single antenna 4.DBAC+DBDC Its DBDC feature (i.e., dual MAC, allowing two APs to work simultaneously on 2.4/5.8GHz, compared to DBAC which supports only one AP) benchmarks against high-end functions of Western counterparts, placing it ahead of domestic counterparts in the Chinese market in terms of WiFi chip technology.     The WQ9101 features two interface designs: USB and SDIO. Its USB module, the O9101UB, has also demonstrated top-notch performance in streaming tests.     The WQ9101, with its support for DBDC and top-notch performance, excels in high-reliability and complex scenarios such as video conferencing, HDMI transmission, projectors, commercial displays, robotics, and industrial control settings. Meanwhile, the WQ9201 goes a step further with the following parameters: 1.Dual-band 2.4/5.8GHz 2.a/b/g/n/ac/ax 3.2T2R dual antennas 4.DBAC (2T2R) or DBDC (1T1R)   Other notable features include: 1.Enhanced power management, with lower current compared to similar products 2.Multiple interfaces including PCIe, SDIO, and USB 3.Reserved RISC-V for differential development, such as power-saving mechanisms for WiFi 4.Compatibility with domestic operating systems This makes it suitable for a wider range of applications including set-top boxes, laptops, tablets, and more. Corresponding modules include O9201UB, O9201SB, and O9201PM.     From the perspective of the development of domestic WiFi chips, low-end chips have already achieved cost-effectiveness comparable to their Taiwanese counterparts, while mid-to-high-end chips can compete head-to-head with Taiwanese counterparts. However, there still exists a gap between top-tier chips such as WiFi 6E and WiFi 7 and their Western counterparts. Nevertheless, with the efforts of domestic WiFi manufacturers, this gap should be narrowing rather than widening. We will witness more applications of domestic WiFi modules in various scenarios.            

On January 8, 2024, the Wi-Fi Alliance announced the Wi-Fi CERTIFIED 7 certification, introducing powerful new features aimed at enhancing Wi-Fi performance and improving connectivity in various environments. This certification marks the official beginning of the WIFI7 era. On January 10, Bingo Corporation announced the launch of the world's first WIFI7 public network at the CES exhibition, marking the official transition of Wi-Fi 7 technology into a new phase of practical application. Against the backdrop of this technological revolution, let's explore the differences between WIFI7 technology and previous Wi-Fi technologies to gain a more comprehensive understanding of this new era in wireless network technology and prepare for the arrival of the WIFI7 era.   In the previous article, we provided a detailed introduction to the Multi-AP Coordination technology in WIFI7, and those interested can click the link to learn more: https://www.wifibtmodule.com/news/the-era-of-wifi-7-has-officially-arrived-165518.html.In this article, we will discuss the QAM modulation and 320MHz bandwidth in WIFI7 technology.     Orthogonal Amplitude Modulation (QAM) is a core technology in WIFI7, representing a digital modulation technique that maps digital signals onto multiple carriers with varying amplitudes and phases to achieve high-speed data transmission. In QAM, we often encounter a numerical value, which refers to the Modulation Symbol. The modulation symbol serves as the fundamental unit for carrying data in a specific modulation scheme. It signifies a particular signal state, and the information it contains can be transmitted and received through the modulation and demodulation process, typically represented by a set of discrete signal states or symbol points. Each modulation symbol represents a certain quantity of bits, or bits, depending on the modulation scheme and modulation order employed.     QAM modulation represents different modulation symbols by varying the amplitude and phase of the signal in two dimensions. In QAM, the number of modulation symbols is related to the modulation order. For instance, 16-QAM signifies 16 different modulation symbols, 64-QAM indicates 64 different modulation symbols, and the progression continues with WIFI4 using 64-QAM, WIFI5 employing 256-QAM, WIFI6 incorporating 1024-QAM, and WIFI7 introducing 4096-QAM modulation. Each modulation symbol can carry a specific amount of bit information, and with higher modulation orders, each symbol carries more bits, resulting in higher data transmission rates. Taking the example of the WIFI7 card O7851PM from Shenzhen QOGRISYS Technology Co., Ltd., which integrates 4096-QAM modulation technology, each modulation symbol can carry 12 bits. Compared to WIFI6 with 10 bits per symbol, this means a 20% speed improvement under the same encoding conditions.     Maximum 320MHz bandwidth   The bandwidth of WIFI is akin to the width of a road, where a wider bandwidth corresponds to a broader road, allowing for faster transmission of information.       In the early stages of WIFI and other wireless technologies like Bluetooth, the 2.4 GHz frequency band has been extensively shared, leading to significant congestion in that range. While the 5GHz frequency band offers more bandwidth compared to 2.4GHz, translating to faster speeds and greater capacity, it also faces congestion issues.   To achieve the goal of maximizing throughput, WIFI7 will continue to introduce the 6GHz frequency band and incorporate new bandwidth modes, including continuous 240MHz, non-continuous 160+80MHz, continuous 320MHz, and non-continuous 160+160MHz, providing users with a faster and more efficient data transmission experience.     Taking the O7851PM card module from QOGRISYS as an example, the O7851PM supports DBS and operates on both 2.4 GHz + 5 GHz and 2.4 GHz + 6 GHz frequency bands. Additionally, it also supports HBS, offering a maximum bandwidth of 320MHz in the 5GHz + 6GHz frequency bands or the standalone 6GHz frequency band. The maximum data rate reaches up to 5.8Gbps, providing users with an enhanced connectivity experience.   In conclusion, with the official release of WIFI7 technology, wireless networks have entered a new era, bringing forth enhanced performance and a more stable connectivity experience. The continuous evolution of QAM modulation technology and the introduction of a maximum 320MHz bandwidth have significantly improved the data transmission rates and efficiency of WIFI7. The modulation upgrades from 1024-QAM to 4096-QAM, along with the introduction of new frequency bands and bandwidth modes, provide users with faster and more efficient wireless connectivity options.     QOGRISYS Technology's O7851PM card module, serving as an exemplar of WIFI7 technology, showcases its robust performance with integrated 4096-QAM modulation technology and support for a maximum 320MHz bandwidth. This not only delivers an enhanced connectivity experience for users but also opens up new possibilities for the future development of wireless communication. With the advent of the WIFI7 era, we can anticipate further innovations and advancements, ensuring that wireless networks can provide more powerful and reliable services in various environments.
