This is a new 3D UX network design tool making complex 5G network design accurate, easy and fast. Thanks to a Visual Object Palette, users can easily add buildings/shrubs and other changes to an identical virtual environment. Network design data is provided by phase for easy design following the system’s steps. Digitized simulation results visually marked on the 3D map allow quick grasp of strong/weak signal spots. Without complex data entry, users can intuitively operate (move/rotate) base stations with the mouse.
