Grid Algorithms for Cellular Coverage Analysis

Analyzing network coverage is a core task in modern telecommunications and spatial data analysis. This course teaches you how to model a physical space—like a shopping mall—as a cellular signal grid and programmatically identify the largest contiguous regions of strong coverage. You will start by understanding how grid systems represent physical environments, learning the core mathematical and logical definitions of contiguity and signal thresholds. Next, you will explore foundational traversal techniques, including Depth-First Search and Breadth-First Search, adapted specifically for two-dimensional grid structures. What you will learn: Understand how to represent cellular signal strengths using two-dimensional matrices; Define and identify contiguous regions using 4-directional and 8-directional neighbor connectivity; Implement grid traversal algorithms to calculate the exact size of connected network zones; Apply threshold filtering to isolate strong signal areas from weak coverage zones; Analyze the computational efficiency and time complexity of your grid search algorithms. You will begin with basic definitions of matrix coordinate systems before progressing to step-by-step algorithmic logic and clean, readable code implementations. This course is designed for beginner programmers, network analysts, and computer science students who want to apply algorithmic thinking to real-world spatial problems.
