Network optimization flowchart

You have collected all the drive test data, now what next? How do engineers actually use it to fix a network? Do they just change the things randomly? Of course not. They follow a clear step-by-step process to turn that real-world data into a better experience for every user. Today, I'll walk you through the 3 key phases of network optimization after a drive test. The first phase is a single site verification. This is a hygiene check. Imagine a new cell tower has got built. Before we worry about how it works with its neighbors, we have to make sure it was built correctly. Engineers visit the site to check is the antenna pointed in the right direction, is it at the planned height or not, are all the cables connected properly and they also verify any software settings like transmitted power or any configuration related to power boosting. And this step ensures the basic building block is solid before we connect it to the rest of the network. we move to the cluster optimization. A city…
