Abstract :
Ray-tracing has become increasingly popular for dense urban microcell prediction, and the results are generally better than can be obtained with other techniques, but questions remain on the sensitivity of the ray tracing algorithms to a number of parameters, including: building materials, environmental parameters, and various types of errors. A number of parameters are tested for its sensitivity to changes in the error of a nominal prediction
