Before we talk the SDIO WiFi Module, let's take a quick look at the SDIO, which literally means the I/O interface of SD. SD itself is the standard for memory cards, but now we plug SD into some of the peripheral interfaces , and from that comes what we called the SDIO. It can also be said that SDIO is an interface developed on the basis of SD card. It is not only compatible with previous SD CARDS, but also can connect the external periphery through the I/O pin of SD and transmit data to these periphery through the I/O data bit on SD.   So SDIO WiFi Module, which is simply an embedded module based on the SDIO interface and compatible with wireless network standards. The built-in wireless network protocol IEEE802.11 and TCP/IP protocol stack can realize the conversion of user's main platform data from SDIO port to wireless network.

With the development of wireless transmission technology, high-definition wireless HDMI extender products have begun to be applied to various scenes in life. It is widely used for home high-definition video images at the same frequency, in classroom education and conference office, as a courseware display and enterprise information display, or as a camera and other devices, the HDMI high-definition picture is wirelessly transmitted to the corresponding device for recording and broadcasting.After getting rid of the connection of the wired connection, the wireless projection screen is more convenient to use.   Wireless screencast can transmit images in real time and transmit the images to the required devices in time, providing a very convenient experience for users with different needs. In the past few years, a large number of wireless HDMI extender products have emerged on the market, but in the complex environment and long distance, 2.4G is used for transmission. Because of 2.4G interference, the quality of image transmission is greatly declined. With the 802.11 5.8g gradually becoming the mainstream in recent years, the cost of the wireless module, which is the core component of the wireless projection screen product, is greatly reduced, which makes the related wireless HDMI extender products continue to be innovated, making it suitable for various subdivisions, wireless HDMI extender can be said to have a bright future.   Oflycomm specially developed the 8121N-UH module for the wireless picture transmission field, adopting Qualcomm chip, dual antenna design, adopting 802.11 5.8G frequency band to avoid signal interference of 2.4G frequency band, power up to 19dBm (54M*2), excellent in all aspects of distance and penetration, suitable for wireless HDMI extender, long-distance wireless transmission and other fields.   At present, the performance of the market is stable, and the mainstream products with excellent transmission quality and speed generally adopt the Hisilicon main chip , and use H.264 encoding to transmit high-definition audio and video below 1080P. However, the main chip using H.265 encoding is equipped with 8121N-UH module to transmit 4K audio and video. With the increase of 4K sources, 4K wireless HDMI extender products will also become mainstream.   Due to different solutions or designs, product cost and performance will be quite different. Oflycomm has been committed to providing and assisting customers to optimize product RF solutions.      .

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.

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.
