The goal is to find the Cell ID of the most reliable nearby tower along with its Radio Type to guide him to the best place for reception.

Investigation Steps

1. Finding the Location: I started by locating the Arab German Company on Google Maps to get a sense of the exact area.

2. Locating Nearby Cell Towers: Using OpenCellID, I examined the cell towers around the company’s location. Several towers were nearby, but after assessing the options, the most stable one I found was a 3G UMTS tower.

The first thing I did was going to google maps and finding the Arab German Company in Cairo location

After finding, its location, the next step is to find the nearby cell towers. To that I used

• OpenCellId

Going to the location of the company on the website's map, I found a lot of Towers, but the most stable one was a 3G UMTS tower
