Radio Modelling in Cities

When planning or modelling a radio network the underling terrain, clutter and building layers will impact the outputs from your study. With the growing demand for wireless in our cities we see a growing demand for high resolution data sets for coverage and propagation modelling.

Free to use data sets are available worldwide with a planimetric resolution of 20-30m. This is great for wide-area rural coverage but lacks accuracy when modelling dense urban environments. Utilising high resolution DTM and DSM can increase the accuracy of model predictions before team members are set to site to confirm site viability.

What do you mean by high resolution?

Within built up areas such as cities the height of buildings can change from block to block. Using a surface model that shows the details to a 1m resolution will allow greater accuracy in modeling prediction. Propagation models must be tested and optimised for use with these datasets.

Higher frequency spectrum requires line-of-sight between links are becoming more common. The path profile function can show the individual building outlines and line of sight required for a point to point link.
