Long-distance link transmission in the Internet of Things (IoT) typically refers to wireless transmission technologies with single-hop transmission distances reaching kilometers or even over ten kilometers. With the increasing demand for widespread coverage in IoT, long-distance link transmission has become an important research direction. It holds significant application value in practical scenarios such as ocean monitoring, outdoor environmental sensing, and emergency disaster relief. However, there are still challenges in long-distance link transmission, including difficulties in precise synchronization, low transmission rates, and weak transmission security, which have become bottlenecks limiting the capabilities of long-distance transmission in IoT.The research conducted by Shengpeng Zhu from Beijing University of Posts and Telecommunications focuses on three aspects: improving synchronization accuracy of long-distance links, enhancing transmission rates, and ensuring transmission security. Progress has been made in precise synchronization, link anti-interference, and continuous authentication.
