The study of radio propagation models for urban areas prediction [articol]

Abstract

The development of the mobile communications and the integrated services provided using the cellular networks has exploded in the last years, and the expansion keep an asceding slope, due to continuous request of new services on the mobile communications market. Although the radio cellular networks already exist, new technologies evolve, and that imply the usage of new frequncy bands and new propagation models to caracterise the propagation problems that can appear.
