Urban REMs dataset We present a Radio Environment Map (REM) dataset of urban scenarios. Each map provides coverage information in areas from 2290 x 3670 m2 to 3810 x 5160 m2 with a resolution of 10 m. Coverage areas are sampled from Colombian cities (Armenia, Bogota, Cali, Ibague, Manizales, Medellin, and Pasto) and U.S. cities (Columbus and Washington). The simulations include topographic and building vector database information, and Intelligent Ray-Tracing as propagation model.
