WIFI7: Embracing a New Era of Wireless Connectivity

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.

The difference between WIFI6 and WIFI5 lies in what aspect?

In the digital era, as wireless networks continue to evolve, WIFI technology, one of our primary means of daily connectivity, is also undergoing constant upgrades. Over the past few years, WIFI5 has been the preferred standard for many users, providing us with reliable wireless connections. However, WIFI6 has now emerged, introducing a range of new features and being hailed as "High Efficiency WIFI." Let's delve into the differences between WIFI6 and WIFI5, explore the advantages brought by this new technology, and consider the position of WIFI5 in this technological evolution.   Compared to the currently prevalent WIFI5 technology, WIFI6 demonstrates superior performance in multiple aspects. WIFI6 not only boasts faster speeds, support for more concurrent devices, and lower latency but also operates with greater energy efficiency. It adopts OFDMA technology similar to 5G, combined with 1024-QAM high-order modulation, enabling a maximum support of 160MHz bandwidth and nearly tripling the speed compared to WIFI5. Through intelligent frequency division technology, WIFI6 can accommodate concurrent connections for more devices, increasing the access device capacity by four times. Moreover, the reduction of queuing phenomena is facilitated by multi-device concurrent connections, actively avoiding interference and reducing latency by two-thirds. During terminal device standby, WIFI6 also supports on-demand wake-up functionality, effectively reducing the power consumption of terminal devices by 30%. These advanced features make WIFI6 a significant technological upgrade in the current field of network communication.     Under the WIFI5 standard, communication between devices can be likened to a single-channel transmission, where at any given moment, only one device can communicate with the router. Even if other devices are idle, they cannot transmit data simultaneously. If any device experiences interference, the entire communication channel may be affected, similar to a blockage in the entire communication process. In contrast, under the WIFI6 standard, communication has been improved. Multiple devices can communicate in a more flexible manner simultaneously, forming a more efficient multi-user transmission. Devices can be grouped into teams, and each team can independently transmit data without interfering with each other. If a particular device experiences interference, only the team to which that device belongs will be affected, without impacting the entire communication process. This makes the WIFI6 standard more powerful and reliable in the face of interference.     To enhance the device access capacity of WIFI networks in densely populated scenarios such as exhibition venues and sports stadiums, WIFI6 has introduced a technology known as BSS coloring. In traditional WIFI communication, devices adhere to the "listen before talk" principle, meaning they wait until other signals on the same channel are detected to be finished before initiating communication. However, BSS coloring technology allows devices to assess whether other signals might impact communication through specific markers. If a WIFI6 device reads the marker and determines it as "non-impactful," it will initiate communication directly, thereby reducing wait times and effectively improving the speed and reliability of wireless networks.     This is a significant improvement, but WIFI5 devices do not support this technology. WIFI5 devices do not carry markers in their transmitted signals, so surrounding devices cannot determine from these unmarked signals whether they might affect their own communication. The only solution is to remain silent, leaving time for these older devices that do not support the new technology.     In such a scenario, once WIFI5 devices initiate communication, it may force WIFI6 devices, which could have communicated, to remain silent. This highlights the advantages of adopting WIFI6 in high-density environments, while traditional WIFI5 devices become a limiting factor for overall communication efficiency. In summary, WIFI6, as the new standard for wireless connectivity in the digital era, is favored by many users due to its higher speed, support for more concurrent devices, low latency, and low power consumption.     Shenzhen Ofeixin Technology Co., Ltd fully leverages the advantages of WIFI6 technology and has successfully launched the WIFI6 module O2064PM. This module incorporates Qualcomm's QCA2064 WIFI 6 chip, featuring ultra-high integration and outstanding performance. The O2064PM module is compatible with IEEE802.11a/b/g/n/ac/ax 2x2 MIMO wireless standards, supporting Dual-band simultaneous (DBS) operation in the 2.4GHz and 5.8GHz frequency bands concurrently. It utilizes an M.2 PCIe interface, achieving a maximum data rate of 1800Mbps. After market validation, the O2064 module has been successfully mass-produced and stands out uniquely in the market.     Simultaneously, Ofeixin continues to innovate, keeping pace with the trends of the times, and has successfully developed and launched the WIFI7 module O7851PM. Based on Qualcomm's WCN7851 chip, the O7851PM utilizes an M.2 PCIe interface with dimensions of 22302.7mm, achieving a transmission rate of up to 5.8Gbps. It supports the latest WIFI7 technologies such as 4096QAM, 320MHz bandwidth, Multi-RU mechanism, Multi-LINK multiple link mechanism, CMU-MIMO, and collaborative debugging of multiple APs, making it an ideal choice for advancing towards higher levels of wireless connectivity.

This certification introduces a range of powerful new features aimed at enhancing Wi-Fi performance and improving connectivity in various environments. WIFI 7 supports emerging applications such as multi-user AR/VR/XR, immersive 3D training, electronic gaming, hybrid work, industrial IoT, and automotive technologies. It is anticipated that by 2028, Wi-Fi 7 will see the market entry of 2.1 billion devices, with smartphones, PCs, tablets, and access points among the early adopters of Wi-Fi CERTIFIED 7 certification.     Broadcom, CommScope's RUCKUS Networks, Intel, MaxLinear, MediaTek, and Qualcomm, among other companies, have formed the certification testbed and are among the first to receive Wi-Fi CERTIFIED 7 devices. The introduction of this certification will drive widespread adoption of Wi-Fi 7, offering users a faster, more efficient, and reliable wireless network experience.   WIFI 7 introduces a range of cutting-edge features, such as 320MHz bandwidth, 4096-QAM, Multi-RU multi-link operation, enhanced MU-MIMO, and multi-AP collaboration technologies, aiming to provide higher data transfer rates and lower latency.     Among them, Multi-AP Collaboration is a significant innovation in Wi-Fi 7. Within the 802.11 protocol framework, various access points (APs) primarily engage in collaborative activities such as channel optimization selection, AP transmit power adjustment, load balancing, and spatial reuse for efficient resource utilization. However, in practice, the collaboration between APs is relatively limited. To further enhance the efficiency of radio frequency resource utilization in specific areas, Wi-Fi 7 introduces collaborative scheduling among multiple APs. This includes coordination planning in both time and frequency domains for neighboring cells, interference coordination between neighboring cells, and distributed MIMO (Multiple Input Multiple Output), effectively reducing interference between APs and significantly improving the utilization of airborne resources.   The Multi-AP Collaboration scheduling in Wi-Fi 7 encompasses the following aspects:   Coordinated Orthogonal Frequency Division Multiple Access (Co-OFDMA):   By coordinating and allocating subcarrier resources among different APs, multiple APs can simultaneously engage in parallel communication on different subcarriers. This allows for the sharing of spectrum resources among multiple APs, thereby improving spectrum utilization efficiency and network capacity.       Coordinated Spatial Reuse (Co-SR):   Coordinating the transmission and reception time slots of different APs in the spatial domain, allowing different APs to simultaneously transmit data in adjacent areas, reduces interference between different APs, thus improving spatial reuse efficiency, network capacity, and throughput.     Coordinated Beamforming (Co-BF):   Through Coordinated Beamforming, multiple APs collaborate to concentrate signal energy and alter antenna radiation direction, transmitting the wireless signal in a more directional manner to specific user devices. This enhances signal coverage, improves link quality, and increases transmission efficiency.     Coordinated Joint Transmission (Co-JT):   Allowing the combination of data from multiple APs into a more powerful signal, simultaneously transmitting coordinated data to the same user device, improving the reception signal quality, transmission rate, and coverage range of the user device.     Coordinated Time Division Multiple Access (Co-TDMA):   Allowing multiple APs to transmit data in different time slots, through coordinated scheduling and allocation of time resources, avoiding conflicts and interference between APs, reducing transmission latency, providing a more stable and reliable connection, and improving network capacity and spectrum utilization efficiency.   Basic Service Set Coloring Mechanism (BSS Coloring):   By identifying and distinguishing different BSSs, it avoids mutual interference between multiple Wi-Fi routers or APs on the same channel, thereby enhancing the performance and reliability of the Wi-Fi network.     Clear Channel Assessment (CCA):   Dynamic Channel Sensing technology used to detect, perceive, and assess channel activities in the surrounding environment. It adjusts based on real-time channel conditions, aiding APs in selecting relatively idle channels to enhance performance and reduce interference with other Aps.   In the wave of technological innovation in Wi-Fi 7, Shenzhen Ofeixin Tech Co., Ltd.'s O7851PM wireless Wi-Fi 7 card has emerged as a standout performer. As a leading product with Wi-Fi CERTIFIED 7 certification, it is designed with the Qualcomm WCN7851 chip, supporting the M.2 PCIe interface with a transmission rate of up to 5.8Gbps. This card features support for the aforementioned Multi-AP collaboration technology and also boasts ultra-low latency (below 2ms), 4096QAM, 320MHz bandwidth, Multi-RU mechanism, Multi-LINK multi-link mechanism, CMU-MIMO, and other Wi-Fi 7 technologies. With its exceptional performance and innovative design, this Wi-Fi 7 card module is poised to be the pinnacle choice leading the Wi-Fi 7 era, providing users with an outstanding wireless connectivity experience.     This article has introduced the Multi-AP Collaboration technology of WIFI 7.

O2066PM Wireless WIFI 6E Network Card Throughput Testing in Windows Environment

Starting from 2023, wireless terminal devices, aside from smartphones, have gradually upgraded to WIFI 6/6E. Devices based on 802.11ax technology can further meet user expectations for superior performance and coverage in the new generation Wi-Fi standard. Users typically focus on the throughput of WIFI modules, and upon receiving samples, they often conduct throughput tests on the modules. In a previous discussion, we introduced the throughput testing of the O2066PM WIFI 6E module in a Linux environment. This article will further test its throughput in a Windows environment. WIFI throughput refers to the actual maximum speed supported by WIFI devices (AP/STA) on the uplink and downlink links. It is a type of stress test that closely resembles real-world usage scenarios, especially as products become increasingly wireless, and wired Ethernet port designs gradually fade away, making it particularly important.     一、Hardware Preparation: PC1: Processor: i5-12400 Memory: 16.0 GB Operating System: Windows 11 (Chinese version) Additional Hardware: PCIE to 2.5G Network Card PC2: Processor: i5-1240P Memory: 16GB Operating System: Windows 10 (English version) Additional Hardware: O2066PM WiFi 6E Module Router: NETGEAR-RAX200 by NETGEAR Antenna:Type: Standard Dual-band PCB Antenna     二、Network Topology     三、Routing Configuration, and Connection Status     四、Screen Room Test   Screening room testing is an ideal environment test, primarily aimed at eliminating interference and assessing the module's actual throughput capacity.   Testing software: IxChariot_670   Throughput test data (actual measurement screenshots):   1、TCP UL: 2.4G HE20(287Mbps),TCP DL: 2.4G HE20(287Mbps)     2、TCP UL: 2.4G HE40(574Mbps),TCP DL: 2.4G HE40(574Mbps)     3、TCP UL: 5G HE20(287Mbps),TCP DL: 5G HE20(287Mbps)     4、TCP UL: 5G HE40(574Mbps),TCP DL: 5G HE40(574Mbps)     5、TCP UL: 5G HE80(1200Mbps),TCP DL: 5G HE80(1200Mbps)     6、TCP UL: 5G HE160(2402Mbps),TCP DL: 5G HE160(2402Mbps)   7、Summarized actual throughput test data:     五、Actual testing in office environment   The actual testing in office environment aims to assess the module's resistance to interference and throughput performance in real-world conditions. The measurements were taken at a distance of 4 meters, with a multitude of active routers, creating a complex testing environment.       六、Summary   1.For high-throughput WIFI module testing, it is necessary to enable multi-threaded testing to demonstrate the module's actual throughput capability. 2.Due to the extreme testing conditions, running TX/RX simultaneously results in significant module heat generation. Therefore, a fan was used throughout the entire process to cool the module. When designing with this module in high-throughput environments (considering mainly TX in AP mode), attention should be paid to heat dissipation issues. 3.Under 2.4G HE40 mode, the throughput rates reached 419.8Mbps (TX) and 447.1Mbps (RX). This indicates that even in the crowded 2.4GHz frequency band, the network card can still provide considerable throughput, making it an ideal choice for high-density user environments. 4.In 5G HE160 mode, the TX and RX throughput rates further increased to an impressive 1678.5Mbps and 1860.3Mbps, respectively, showcasing the outstanding performance of O2066PM in the 5GHz frequency band, supporting higher speeds and larger bandwidth. 5.In actual office scenarios, the O2066PM throughput rate decreased by approximately 700Mbps compared to the shielded room, reaching around 1Gbps, demonstrating good stability.   In summary, the O2066PM, designed based on QCA2066, demonstrates outstanding throughput in both HE40 and HE160 modes. The network card is capable of operating in a wide temperature range from -30 to 85°C, making it well-suited to meet diverse network performance requirements in various application scenarios.

WIFI7: A New Era in Wireless Communication

  In the digital era, wireless communication has become an indispensable part of our lives. With the advent of Wi-Fi 7, we usher in a new era of wireless connectivity. The upgrade to this standard completely revolutionizes our expectations for speed, efficiency, and connectivity. Wi-Fi 7 represents the next generation of Wi-Fi standards, corresponding to the upcoming release of the new revision standard IEEE 802.11be – Extremely High Throughput (EHT). Building upon Wi-Fi 6, Wi-Fi 7 introduces technologies such as 320MHz bandwidth, 4096-QAM, Multi-RU, multi-link operation, enhanced MU-MIMO, and multi-AP coordination. These advancements enable Wi-Fi 7 to provide higher data transfer rates and lower latency compared to Wi-Fi 6. The theoretical throughput of Wi-Fi 7 is expected to support up to 46Gbps, roughly more than four times that of Wi-Fi 6.     Analysis of Key Features of WIFI 7:   Maximum 320MHz bandwidth:   The 2.4GHz and 5GHz frequency bands, being unlicensed spectra, are limited and congested. Existing Wi-Fi encounters inevitable low Quality of Service (QoS) issues when running emerging applications such as VR/AR. In order to achieve a maximum throughput goal of no less than 46Gbps, WIFI 7 will continue to introduce the 6GHz frequency band. It will also add new bandwidth modes, including continuous 240MHz, non-continuous 160+80MHz, continuous 320MHz, and non-continuous 160+160MHz. This represents more than a fourfold increase compared to the previous generation, providing robust support for high-demand applications such as 4K and 8K video (with potential transmission rates of up to 20Gbps), VR/AR, gaming (with latency requirements below 5ms), remote work, online video conferencing, and scenarios involving cloud computing.     Multi-RU Mechanism:   In WIFI 6, each user can only send or receive frames on the specific RU (Resource Unit) assigned to them, significantly limiting the flexibility of spectrum resource scheduling. To address this issue and further enhance spectrum efficiency, WIFI 7 defines a mechanism that allows the allocation of multiple RUs to a single user. Of course, to balance the complexity of implementation and spectrum utilization, the protocol imposes certain restrictions on the combination of RUs. Specifically, small-sized RUs (less than 242-Tone RUs) can only be combined with other small-sized RUs, and large-sized RUs (242-Tone RUs and above) can only be combined with other large-sized RUs. Mixing small-sized RUs and large-sized RUs is not allowed.     4096-QAM modulation technology:   The 4096-QAM modulation technology of WiFi 7 opens up a new frontier in transmission, with each modulation symbol carrying 12 bits of information. Under the same encoding, compared to WiFi 6's 1024-QAM, it achieves a 20% increase in speed. This means that more data can be transmitted in the same amount of time, providing you with a faster and more stable connection experience.     Multi-Link Mechanism:   WiFi 7 not only supports a wider spectrum but also introduces the Multi-Link mechanism to maximize the utilization of available spectrum resources. The working group has defined technologies related to Multi-Link aggregation, including enhanced Multi-Link aggregation MAC architecture, Multi-Link channel access, and Multi-Link transmission. These technologies aim to provide a more reliable and efficient wireless connection.     Support for more data streams, enhanced MIMO functionality:   The powerful MIMO capabilities of WiFi 7 propel your connection to new heights. Supporting more data streams, from 8 to 16, theoretically doubling the physical transmission rate. Additionally, the introduction of distributed MIMO enables multiple access points to collaborate, delivering a more robust and stable wireless connection.     Support for collaborative scheduling among multiple Access Points (APs):   Currently, within the 802.11 protocol framework, there is limited collaboration among Access Points (APs). WiFi 7 not only focuses on the performance of individual access points but also introduces collaborative scheduling among multiple APs. The collaborative scheduling in WiFi 7 includes coordinated planning in both time and frequency domains within cell boundaries, interference coordination within cell boundaries, and distributed MIMO. This can effectively reduce interference among APs, greatly enhancing the utilization of air interface resources.     The launch of WiFi 7 signifies a leap forward in the field of wireless communication, providing stronger and more efficient support for digital living and innovative applications. As experts in the wireless communication domain, Shenzhen Ofeixin Technology Co., Ltd. has successfully developed the WiFi 7 module. Our O7851PM WiFi 7 module, based on the independently developed WCN7851 chip from Qualcomm, is a significant innovation, encompassing all the functionalities of WiFi 7. Stay tuned for our latest achievements!
