The Wireless Internet of Things (IoT) system is a cutting-edge implementation of software-defined radio technology. To ensure robust long-distance communication and counteract interference, it employs an advanced OFDM adaptive adjustment method at the physical layer. This method enhances channel estimation, effectively compensating for Doppler frequency offsets, and supports uninterrupted communication for vehicles moving at speeds up to 80 kilometers per hour. It seamlessly achieves cross-base station switching or dynamic self-organization within network mode. At the MAC layer, it utilizes the 802.11 connectionless mode with a refined frame format, meticulously optimized for mobility. To prevent bandwidth loss due to CSMA/CD conflicts from multiple nodes, the system integrates an intelligent uplink time-division multiplexing approach, ensuring robust support for applications involving multiple video uploads.
