The wireless Internet of Things system is a cutting-edge embodiment of software-defined radio technology. It is meticulously engineered to meet the stringent demands of long-distance and interference-resistant communications. At its core, the physical layer employs an OFDM adaptive adjustment strategy, enhancing channel estimation to counteract Doppler frequency shifts effectively. This robust design supports vehicular speeds of up to 80 kilometers per hour, enabling seamless cross base station transitions or dynamic self-organizing networks in self-organizing network mode. At the MAC layer, the system leverages the 802.11 connectionless mode, fine-tuned for mobility with enhanced frame formats. To mitigate bandwidth loss from multi-node CSMA/CD conflict detection, the system innovatively implements uplink time-division multiplexing. This strategy empowers applications requiring multiple video uploads, ensuring a smooth, uninterrupted flow of data.
