Maximizing Cellular Coverage In LA With Viewshed Analysis

Goal: This project assesses the current cellular coverage of T-mobile in LA County and three possible scenarios to improve coverage.

Methodology

Viewshed analysis was conducted using ArcMap 10.7 using T-mobile cell tower locations and a 3-arc-second resolution SRTM Void Filled DEMs from USGS Earth Explorer. DEMs were combined using the raster mosaic function.

Maps

Current estimated T-Mobile cellular coverage in LA County

Estimated T-Mobile cellular coverage in LA County if three new cellular towers are added in underserved areas

Estimated T-Mobile cellular coverage in LA County if the height of all existing cellular towers is increased by 10 meters

Estimated T-Mobile cellular coverage in LA County if the maximum range of all existing cellular towers is increased by 5 km
