In this chapter, you injected our TelZaViBa tool with more functionality. You learned about the ArcGIS coordinates system and how to interact with the map by adding a tool. You then used this tool to add a point to simulate the location of a cell phone. Using the proximity operators, you have used this location to find the closest tower to the cell phone, which is the one the cell phone will be connected to. You were introduced to the display object, which was used to highlight and flash the connected tower. After completing all these tasks, you were ready to finally achieve the chapter aim by displaying the signal strength of that particular cell phone.

In the next chapter, you will complete the TelZaViBa tool by doing the real-time maneuvering; you will learn to read GPS coordinates from a text file, convert them into map points, and simulate a moving cell phone that constantly updates its signal.
