Coverage optimization: overshooting, undershooting, tilting strategy

Overshooting and Its Symptoms

Coverage optimization is the most fundamental activity in network optimization — ensuring every location receives adequate signal strength and quality. The primary tool is antenna tilt adjustment, which controls how far a cell's coverage extends. Overshooting occurs when coverage extends far beyond its intended boundary. Symptoms include UEs served at very high Timing Advance values (indicating large distance), the cell appearing as a strong interferer in distant neighbor lists, and pilot pollution where multiple overshooting cells overlap. In drive tests, overshooting is detected when a…
