The Latest WiFi Standard — WiFi 7

In November 2022, TP-Link released the world's first WiFi7 router. Although WiFi7 is full of gimmicks, the price is relatively high, which also makes consumers wait and see. I have nothing to say about this product,but WiFi7 is still worth talking about. WiFi 7 was established in early 2019, and the protocol group is now named IEEE 802.11 EHT (Extreme High Throughput). In January 2022, MediaTek announced the completion of the industry's first on-site demonstration of WiFi 7 technology, and then WiFi 7 technology entered a high-speed development; at the 2022MWC conference, Qualcomm released the world's first WiFi 7 solution, so what is WiFi 7? WiFi 7 (Wi-Fi 7) is the next-generation Wi-Fi standard, corresponding to IEEE 802.11's upcoming revision standard IEEE 802.11be—Extremely High Throughput (EHT). From the above picture, we can intuitively see that as a new generation of WiFi standard, it has higher speed and lower delay. In fact, in addition to speed delay, WiFi 7 has more and better changes. Compared with WiFi 5 and WiFi 6/6E, WiFi 7 introduces a larger wireless bandwidth (320MHz), a more advanced modulation method (4K-QAM), a more flexible spectrum utilization method (Multi-RU), and a higher space-time New technologies such as multiplexing (16X16 MIMO), more link operations (MLO), and multi-AP cooperation enable Wi-Fi 7 to provide higher data transmission rates and lower latency. Faster: Nearly 4 times the wireless data link performance, the transmission can reach 46Gbps theoretically. More reliable: The new MRU (Multiple Resource Unit) reduces multi-user latency by 25%. More stable link: The new MLO (Multi-Link Operation) reduces single-user latency by 80%, and increases throughput by as much as 300%. New frequency band: Wi-Fi 7 introduces a new 6GHz frequency band (5.925GHz~7.125GHz), increasing the maximum bandwidth to 320MHz to meet high-throughput/low-latency requirements such as 4K video and AR/VR. The multi-link operation, multi-AP cooperative scheduling, time-sensitive network and enhanced retransmission mechanism of WiFi 7 make it more efficient and flexible Although many new functions of WiFi7 are mentioned above, there is still some time before the landing. As the world's leading WiFi module supplier, Oflycomm is now actively introducing Qualcomm WiFi7 chip QCA2067 to make modules to accelerate the landing of WiFi7. In fact, some of the functions in WiFi 7 can actually find some features in the WiFi 6E standard released two years ago, such as supporting 6 Ghz, 4096 QAM and other functions, which can bring us higher network speeds experience.Oflycomm has massly produced the WiFi6E module O2066PM in 2022. If readers are interested in,you can also check it on the official website of Oflycomm.




  AR and VR have always been hot in recent years. IDC believes that the AR and VR markets will develop rapidly at a compound annual growth rate of 56% in the next five years. AR (Augmented Reality) and VR (Virtual Reality) have been hot in the market in recent years. According to the latest report from market research company IDC, the AR and VR helmet market shipments are expected to grow from 13.7 million in 2017 to 81.2 million in 2021. with a compound annual growth rate of approximately 56.1%. Products in the AR and VR markets face a serious pain point: limited mobility, and the delay problem must be solved. To solve this pain point, it is necessary to consider switching from wired to wireless, and the most high-throughput and low-latency wireless application is WIFI technology. From the perspective of previous industry applications, WIFI5 seems to be unable to completely solve the delay problem due to the influence of its own protocol when the technology has not been iterated, and its delay is generally 30ms in the industry. But the new WIFI6/6E and the later new WIFI7 protocol can reduce the delay exponentially. Qualcomm released the new QCA2066 Wi-Fi 6E wireless chip last year, which supports VR streaming via Wi-Fi and achieves "VR-Level latency", providing a solid foundation for this fast-growing industry segment. O2066PM module is based on Qualcomm QCA2066 chip design, fully supports WIFI6E protocol, 160M bandwidth, theoretical 3Gbit/s transmission rate, supports DBS stacking technology, and its support for 6G frequency band is a sharp tool to solve interference and delay. In traditional tethered mode, the VR headset has a resolution of 3840 x 2160 pixels per eye and a refresh rate of 75 Hz. It either supports 2560 x 1440 pixels per eye at 120 Hz. Under the updated demand, 1080p and 4K can no longer meet the demand, and 8K is the trend. The measured throughput of O2066PM is 2.1Gbit/s, which greatly supports the demand for high-standard applications. At present, O2066PM has been designed in the customer's VR product and participated in the 2023CES exhibition, which has won unanimous praise. The transition from Wi-Fi 5 to Wi-Fi 6 and Wi-Fi 6E has been rapid, consumer behavior has fundamentally changed, and customers are now looking for the best possible network connection experience. This has accelerated the momentum for adoption of this new Wi-Fi 6E technology. Also, the world is opening up the 6 GHz spectrum for use. With Ofeixin Wi-Fi 6E module wireless connection solution, WIFI6E will play its important advantages in the fields of AR and VR. We will continue to display the actual measurement data of O2066PM module products for user evaluation.

The Differences Between WiFi 6E And WiFi 6

    Three years ago, Wi-Fi 6 technology entered the market, providing faster speeds, lower latency and improved security for many homes. Since then, a series of technological developments have made the Wi-Fi experience better. In order to solve the congestion problem of 2.4Ghz and 5.8Gh, in 2020, the Wi-Fi Alliance announced the expansion of Wi-Fi 6 from the 2.4GHz and 5Ghz frequency bands to 6Ghz , namely Wi-Fi6E, what are themain improvements of Wi-Fi6E compared to Wi-Fi6? Follow in my footsteps and let's go see it together.     Powerful 6Ghz   Wi-Fi6E has one more E than Wi-Fi6. E stands for "Extended", which means extension and strengthening. It can be seen that WiFi6E is an enhanced version of WiFi6. We can see from the following figure that Wifi 6E has new frequency:6Ghz which is added beside 2.4Ghz and 5Ghz.       The 6GHz band enables higher concurrency, lower latency, and higher bandwidth, with an operating frequency range of 5925 MHz to 7125 MHz (including 7 160MHz channels, 14 80MHz channels, 29 40MHz channels, 60 20MHz channels, a total of 110 Compared with 45 channels of 5Ghz and 4 channels of 2.4Ghz, the capacity is larger and the throughput is greatly improved.   Substantially Improved Wi-Fi Speed   Wi-Fi6E brings a more efficient way to pack data, because it transmits on one signal, thus quadrupling the data rate for a given channel, thereby increasing network speed, the ideal peak rate for Wi-Fi6E Can reach 3.6Gbps.     Greatly Extend Battery Life   Each version of the Wi-Fi standard has improved the battery life of network devices. Since each version brings faster speeds, data transfers are faster and the device doesn't consume as much energy. And, Wi-Fi 6/E will further improve battery saving with a feature called Target Wake Time, it has a feature called Target Wake Time, this feature puts the device into a low power mode, these short sleep times also increase the battery life.     Even though Wi-Fi 6E has improved a lot compared to Wi-Fi 6/5 in various aspects, due to the price of the router and the limitation of network bandwidth, it will take some time for the large-scale popularization of Wi-Fi 6E devices. The mainstream transmission protocol is still Wi-Fi 5 (802.11ac). While major terminal manufacturers are still promoting Wi-Fi 6/5, Oflycomm quietly launched its first Wi-Fi 6E wireless module model O2066PM in early 2022, using Qualcomm's QCA2066(QCA206X) , the new O2066PM is designed in the form of M.2 2230. In addition to supporting Wi-Fi 6E, it also supports Bluetooth 5.2. It is equipped with 2x2 antennas, 2*2 TX/RX streams, supports MU-MIMO, and adds support for the 6GHz frequency band. Support, wireless transmission speed up to 3000Mbps.      



Status of WIFI 6GHz frequency band allocation in the world

With the official opening of MWC2022, the world's most influential mobile communication exhibition, Qualcomm launched the world's first Wi-Fi 7 solution - FastConnect 7800, which supports a peak speed of up to 5.8Gbps and a latency of less than 2ms. The public also expects to transition from the mature WIFI4 and WIFI5 to the updated WIFI6, WIFI6E and WIFI7 products to enjoy a smoother wireless experience. The distribution of the 6GHz frequency band related to WIFI in various regions of the world is also the focus of wireless-oriented people. The frequency band used by WIFI6 is the same as that of WIFI5, namely 2.4GHz+5GHz, but only supports the updated 802.11 AX protocol. WIFI6E and WIFI7 support 2.4GHz+5GHz+6GHz with tri-band at the same time. From the figure, we can see that the frequency range of 6GHz is 5.925~7.125GHz, with a total bandwidth of 1200MHz, which can accommodate 7 frequency bands of 160MHz, or 14 frequency bands of 80MHz and 60 frequency bands of 20MHz, which greatly expands the WIFI frequency band and reduces the frequency of daily WIFI. Frequency interference will decrease a lot. At present, the division of WIFI 6GHz in various regions of the world has not been completely clear. The following is the classification status of each major region. Country and Region Classification Status of 6GHz The US,Canada,Latin America All for WIFI EU, UK 5.925~6.425GHz for WIFI Japan, Korea All for WIFI Australia New Zealand undecided China undecided Brazil, Chile All for WIFI It can be seen from the chart that overseas use of WIFI 6GHz is relatively clear, and my country has not yet determined it, so the current WIFI6E and WIFI7 cannot use the 6GHz frequency band in principle. However, we can also experience better performance than WIFI4 and WIFI5 through the new protocols of WIFI6 and WIFI7. Similarly, chip manufacturers also allow users to experience better throughput performance through technical aspects. For example, Q2064PM1 designed with Qualcomm QCA206X series chips, although only supports 2.4GHz+5GHz, but through DBS (Dual-Band Simultaneous) concurrent dual-band technology, 2.4GHz+5GHz is combo, which further improves the transmission throughput.



Throughput—Qualcomm WIFI6E module Q2066PM1

In the past two years, people have gradually transitioned from the new term WIFI6 to using WIFI6 devices, such as routers, mobile phones and other products. Other WIFI6 products are also more and more now. With the rapid iteration of technology, WIFI6E and WIFI7 are also well known to everyone. Is it worth spending more to replace and update products at this stage? Here we take a look at the advantages of WIFI6E through the throughput test,let’s check the core indicator of WIFI6 E. Qualcomm has launched the latest WIFI6/6E series of iterative WIFI chips, the QCA206X series, covering the full range of WIFI6/6E product lines. This test module Q2066PM1 is based on the latest QCA2066 WIFI6E chip. Q2066PM1 basic parameters: PCIE M.2 interface; support 802.11a/b/g/n/ac/ax; support 2*2MU-MIMO; DBS stacking technology supports up to 3Gbps rate; bandwidth supports 2.4GHT20/40, 5G/6G Support HT20/40/80/160; bluetooth supports BT5.2; support LTE. A close-range test environment: 1、 AP side:Linux+ Q2066PM1 2、 STA side:Win10+ Q2066PM1 3、 Software/Hardware:iperf professional throughput test software/M.2 adapter board     Before the test, the CPU performance of the PC needs to be adjusted to the maximum, otherwise the speed under the high throughput of WIFI cannot be shown.   1).2.4G HE40(standard:574Mbps):       2) 5G HE160(standard:2042Mbps)       3)DBS(2.4G HE40+5G HE160)       4).DBS(2.4G HE40+6G HE160)     Arrange the above data into the following table:                2.4G 5G 2.4+5G(DBS) 2.4+6G(DBS) Bandwidth HE40 HE160 2.4G HE40+5G HE160 2.4G HE40+6G HE160 Theoretical Rate 574Mbps 2400Mbps 3000Mbps 3000Mbps Tested Throughput 457Mbit/s 1.75 Gbit/s 2.1Gbit/s 2.1Gbit/s   From the measured data, the 5GHz frequency band is basically the same as the 6GHz frequency band. The key is that WIFI6E has increased the 6GHz frequency band. The frequency band also begins to feel "grabbing the position", and the 6GHz frequency band added by Wi-Fi 6E can solve this problem for you very well. There are more performance tests for WIFI6E, we will continue to do so, please pay attention to us, Oflycomm will bring you more information.



WiFi 6/6E—May be Necessary Metaverse In the Future

With the rapid development of the Internet of Things, the WiFi market continues to increase. According to IDC, global WiFi chip shipments will reach 4.9 billion units in 2022, accounting for more than 40% of the shipments of major mainstream interconnection solutions. It can be said that WiFi is One of the most important solutions among mainstream. With the following significant advantages, WiFi 6 has rapidly penetrated the WiFi market. 1. Faster speed, support for more concurrent devices, lower latency, and lower power consumption   2.Under the WiFi 6 standard, a fleet departing at the same time can form a team of at least 26 adjacent vehicles. Each team can be sent to different customers. If a vehicle fails (disturbed), it willonly affect the team.     3. The interference coloring technology adopted by WiFi 6 can mark the neighbor network signal frames coming through the wall so that the user's router can ignore them. WiFi signals between neighbors can transmit data on the same channel at the same time without interfering with each other, reducing the interference rate by 30%.   3. WiFi 6 negotiates the timing of WiFi wake-up with the terminal, and wakes up on demand, without power consumption during sleep periods.   Therefore, many chip manufacturers believe that the penetration rate of WiFi 6 chips in the PC market will reach 30% this year, and the penetration rate in the router market will reach by 20%, which will further double next year. It is estimated that in 2023, chips supporting the WiFi 6 standard will account for 90% of the total WiFi chips, and the WiFi 6 chip market will be 24 billion yuan. At the same time, many module manufacturers have recently launched WiFi 6 and WiFi 6E modules. As a company dedicated to providing customers with complete IOT solutions, Shenzhen Ofeixin Technology Co., Ltd. has also actively responded to the rapid changes in the market and launched the corresponding Wi-Fi 6(Q2064PM1) and Wi-Fi 6E modules(Q2066PM1), the design of Q2064PM1 and Q2066PM1 is based on Qualcomm's QCA206x chip.Wi-Fi 6 modules Based on Q2064PM1, M.2 interface, complies to IEEE802.11 a/b/g/n/ac/ax standard, supports DBS (2.4G and 5.8G), the transmission rate can reach 1.8Gbps. The Wi-Fi 6E module is based on the Q2066PM1, M.2 interface and conforms to the IEEE802.11 a/b/g/n/ac/ax standard. It not only supports 2.4G and 5.8G, but also 6G, and supports DBS (2.4 G+5.8G or 2.4G+6G), the transmission rate can reach up to 3Gbps. The main parameters of its products are as follows:         Wi-Fi 6 Wi-Fi 6E Model NO. Q2064PM1 Q2066PM1 Interface M.2 M.2 Bands 2.4/5.8 2.4/5.8/6G Wi-Fi BT Standard a/b/g/n/ax+BT5.2 a/b/g/n/ax+BT5.2 Dual Band Simultaneous 2.4+5.8 2.4+5.8 or 2.4+6   It is precisely because of the close integration of various internet devices and activities such as social interaction, entertainment, games, work, display, education, and trading that human life style has been greatly changed, and the term "metaverse" has gradually entered people's field of vision. This year, the concept of metaverse has exploded. Some observers believe that although metaverse is still in the stage from 0 to 1, the explosive power shown recently is similar to the cluster effect experienced by the Internet in 1995. The future development should not be underestimated. At present, many technology companies have begun to launch devices that support WiFi 6/6E. Because the application of underlying technologies such as virtual reality, artificial intelligence, blockchain, big data, 5G communications, and wearable devices is becoming more and more mature, it is finally possible to create a "metaverse", and people are about to usher in an unpredictable future.      



Analysis of Low Power IP Camera Market

According to industry surveys, from 2018 to 2020, the home intelligent vision (consumer IPC) market has grown rapidly. Since 2016, the compound annual growth rate of China's home camera sales has reached 53.5%. After the explosive growth in previous years, home camera market is now at a relatively mature. Looking at the world, global home camera shipments in 2020 will be 88.89 million units, which is about 2.2 times that of the Chinese market. The compound growth rate in the next five years is expected to be 19.3%. According to this calculation,Shipments of home cameras will exceed 200 million units all over the world in 2025 In the past few years, the home camera market was dominated by long-power-supply cameras, with low cost and large shipments. However, along with the lower technical threshold of traditional long-power-power cameras, the market competition was extremely fierce, and there was a shortage of chips starting in 2020. As well as the sharp increase in raw material prices, the profits of various enterprises have been drastically reduced, and enterprises at home and abroad have to seek new revenue and profit growth points. Under this circumstance, companies and chip manufacturers have set their sights on the low-power IPC market. Its biggest feature is ultra-low power consumption and battery-powered power, which perfectly solves the problems of external power supply and network wiring and completely solves the problem. The cable restraint, especially for countries with high labor costs such as overseas, Europe and the United States, easily solves the problem of high installation costs.     Next, several common low-power IPC solutions will be introduced: 1.Hisilicon Hi3518EV300+Hi3861L The Hi3518EV300 chip is widely used in the field of video surveillance. Most low-power solution providers use this chip as the main component, with Hi3861Lwifi module. In order to achieve low power consumption and accelerate the device wake-up speed, this solution generally uses the LiteOS system, HiSilicon With its advantages of high integration, short development cycle, low development difficulty, low price and local services, it has grown rapidly in this market and its market share has reached 70%. Half a year after HiSilicon was sanctioned, other chip manufacturers were unable to meet market demand, making the market lack of chips more seriously. At the same time, due to the difficulty of switching low-power solutions, there was a supply gap in the middle. 2.Ingenic T31ZL/T21+Hi3861L/MTK7682 Ingenic firstly set foot in low-power products is T21, and has now switched to T31 chip, adopting 22nm specifications, currently it is mainly equipped with MTK7682 or Hi3861L modules, in fact, in 2020, Ingenic's low-power solutions have many problems. With the increase of customers connecting with Ingenics solutions, the optimization and improvement speed of the original factory has also been accelerated. Ingenic’s low-power solutions have now become one of the mainstream solutions in the market. Firstly,more stable it has been, the second is that the development documentation of the Ingenic program is relatively complete and the development difficulty is relatively low. 3.Realtek RTL8715 RTL8715 integrates the main chip and wifi, which not only has advantages in cost, but also provides customers with convenience in technical support. At the same time, it adopts a small RTOS system to speed up the startup speed of the device and is also friendly to power consumption. However, due to the difficulty of RTOS system development, there are few customers who really adopt this solution, but it also has advantages. Due to the lack of market coverage, the supply has certain advantages. Although HiSilicon has been in the technology blacklist, Hi3861L's outstanding performance in all aspects of low power consumption is still the first choice for low-power solutions. With HiSilicon’s support for other mainstream main controllers, the market’s recognition of Hi3861L is very high. High, Ofeixin also launched the 3161A-SLwifi module based on Hi3861L chip in 2020, the specific parameters are as follows: 1. Supported wireless protocol: IEEE 802.11b/g/n 2. Bandwidth and rate: support 20 MHz standard bandwidth and 5 MHz / 10 MHz narrow bandwidth, providing up to 72.2 Mbit/s physical layer rate 3. Supported modulation technology: Orthogonal Frequency Division Multiplexing (OFDM), Spread Spectrum Technology (DSSS), Complementary Code Keying Technology (CCK) 4. Rich peripheral interfaces: SPI, UART, I2C, PWM, GPIO and multi-channel ADC 5. Working temperature: -40℃~+85℃ 6. Other: integrated high-performance 32-bit microprocessor
