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.
