Therefore, some people call NFC "wireless USB ". Q3: How can I enable mobile phones to support NFC? First, you need to control the IC (NFC Communication Control IC) and antenna for wireless communication. In addition,Security components (SE)You can use e-currency settlement and other servi

advances have made wireless connections an essential technology for the family, not just for convenience. Our laptops, mobile phones, MP3 players, Blu-Ray DVD players, and even televisions all require wireless network connections. To use the wireless functions of these devices, we must have a network connection. As a result, almost every household in a residential area will use the permanent transmission signals sent by wireless devices to block the

If the housing structure is compared to the skeleton, the wiring in the wall is to connect the neural network of the entire House, and the requirements for wiring in modern homes, it is far from satisfying the power lines, closed-circuit television lines, and telephone lines. In these complex line networks, the role of Network cables is becoming more and more obvious. More and more household appliances can connect with network cables, and complete network wiring in Smart Home will become the bas
