Introducing a revolutionary solution for the Internet of Things — our Wireless LTE Connectivity System, brought to you by Safety-Protection (Beijing) Trading Co., Ltd. This state-of-the-art system is an embodiment of advanced software-defined radio technology, meticulously designed to meet the rigorous demands of long-distance and anti-interference communication. Our innovative approach employs an OFDM adaptive adjustment methodology at the physical layer, optimizing channel estimation to effectively mitigate Doppler frequency offsets. This ensures seamless operations, even with vehicles moving at speeds up to 80 kilometers per hour. The system is adept at executing cross-base station switching and supports dynamic self-organizing networks, promising unmatched flexibility. At the MAC layer, we have incorporated the 802.11 connectionless mode with optimized frame formats, tailored to enhance mobility. To overcome the typical bandwidth limitations posed by multi-node CSMA/CD conflict detection, our system features uplink time-division multiplexing. This sophisticated technique significantly bolsters the capability to support applications demanding high volumes of video uploads.
Network Functionality
Our pioneering OFDM/CDMA air interface, a hallmark of the adaptive cognitive wireless Internet of Things system, masterfully merges the superb transmission strengths of OFDM with the robust long-range anti-interference capabilities of CDMA. This innovation has triumphantly achieved product realization within the UHF frequency band.
