With the development of wireless transmission technology, high-definition HDMI wireless on-screen 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 HDMI wireless on-screen products have eme...

On August 9, Huawei developer conference grand opening with a spectacular display of its products and applications. The display of Hisilicon Hi3921 PLC(Power Line Carrier) solution  also attracted a large number of of developers to focus on.The corresponding model of module is named as 3121N-H, developed by FN-LINK and debuted at this conference.Now here is a brief introduction of PLC-IOT. For business or more details,please contact us.   PLC Summary   1、Meaning Of PLC Communication On the AC or DC loading carrier signal to transmit data , such as AC 10Kv，220V/380V，DC 12V/24V 2、Tree Network Architecture Of PLC CCo: Master node, create and maintain the power carrier communication network. STA: Child node PSTA:  Relay node 3、Standard Evolution of PLC 4、Why PLC Under the premise of using power line s...

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 O2066PM is based on the latest QCA2066 WIFI6E chip. O2066PM basic parameters: PCIE M.2 interface; support 802.11a/b/g/n/ac/ax; support 2*2MU-MIMO; DBS stacking tech...

At present, WiFi has officially entered the WiFi6 era. With more and more intelligent devices’ application, WiFi6 based on 2.4GHz and 5GHz frequency band has also become a hot term in the field of wireless transmission. However, with the rapid development of technology, WiFi 6E has also been officially released. Compared with WiFi6, the progress is also a great leap forward.  ▶  What is WiFi6? When it comes to 6,For wifi1, 2, 3... people may not be particularly clear. In 2018, the WiFi alliance decided to directly call the new generation of WiFi technology 802.11ax WiFi6, so it replaced the previous one. Make a simple list: 802.11b — WiFi 1 (1999) 802.11a — WiFi 2 (1999) 802.11g —WiFi 3 (2003) 802.11n — WiFi 4 (2009) 802.11ac —WiFi 5 (2014) ▶   Transmission speed of WiFi6 Here we mainly talk about its theoretical speed: 2.4G...

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...

After wifi embedded applications in the industry in recent years, for the large area of video and other code streams, the bandwidth requirements are relatively high, because of the IEEE 802.11ac standard, the next application for Realtek's 11ac standard wifi module Reference analysis: F11AUUM23-W1 is an RTL8811AU chip, size 23.0*17.0mm, package is LGA-9, power supply voltage DC 3V3, antenna through ANT pin extension or I-pex block external connection, 1T1R single channel maximum transmission rate up to 433.3Mbps , in line with IEEE 802.11a/b/g/n/ac standard, USB interface dual-band WiFi module; F21AUUM13-W1 is an RTL8821AU chip, size 19.0*17.1mm, package is LGA-12, power supply voltage DC 3V3, antenna through ANT pin extension or I-pex block external connection, 1T1R single channel maximum transmission rate up to 433.3Mbps ,...
