Overshooting cells analysis

“

What if a cell tower on a hilltop could broadcast its signals for miles in every direction? It sounds idle right? Actually it is a network engineer's headache. Why would too much reach be a bad thing? This is the problem of overshooting. Overshooting happens when a cell's signals travel much farther than intended. This often occurs with sites on high ground like hilltops or tall buildings. While the height is great for backhaul microwave links, but it causes the cellular signal to cover distant areas which it was never designed to serve. The signal doesn't stop at plant cell edge. It flies over the local plateau and lands in the territory of other cells, sometimes kilometers away and this creates massive unintended overlap which leads to interference. We detect overshooting by different parameters by looking into the report and one of that is the timing advance. It measures how far a user is from the tower in terms of signal travel time. In a normal cell, most users cluster within a…
