Beidou Positioning Antenna PCB Board and Software Design

Short-range wireless transmission has the advantages of strong anti-interference performance, high reliability, good security, limited by geographical conditions, flexible installation, etc., and has a wide application prospect in many fields. Low power consumption and miniaturization are the actual needs of users for current wireless communication products, especially portable products. Short-range wireless communication has gradually attracted wide attention. Common short-range wireless communication has 802.11-based wireless LAN WLAN, blueTooth, HomeRF and HiperLAN (high performance wireless LAN) in Europe, but its hardware design, interface mode, communication protocol and software stack are complex, requiring a special development system, high development cost and long cycle. The end product costs are also high. Therefore, these technologies are not widely used in embedded systems. Common RF products do not have these problems, and short-range wireless data transmission technology is mature, simple function, easy to carry, so that it has been widely used in embedded short-range wireless products.
