Large-Area Super-Resolution 3D Digital Maps for Indoor and Outdoor Wireless Channel Modeling

摘要

This paper reports our recent work on creating the world's first super-resolution 3D digital maps for indoor and outdoor wireless channel modeling. By exploiting the recent technological breakthroughs in unmanned aerial vehicle (UAV), Light Detection and Ranging (LiDAR) and the Simultaneous Localization and Mapping (SLAM) technology, this work develops a surveying system prototype to produce super-resolution 3D digital maps of centimeter-level resolution for large areas covering both indoor and outdoor environments. In addition, the resulting maps are designed to precisely capture building shapes even for skyscrapers with wall material information. It is believed that these new maps can potentially revolutionize the network planning practice commonly performed in the telecommunication industry by providing highly accurate indoor and outdoor channel models. By exploiting these new channel models, wireless service operators will be able to better optimize their wireless networks with reduced necessity of labor-intensive drive tests.
