BTS and Wi-Fi Info

The project involves the development of an Activity that has to be integrated into a general app Android 2.2 or higher. I need an activity that can retrieve and record the list of all GSM/UMTS BTS and all access to Wi-Fi Lan. The activity must provide all information relating to the BTS and must identify them using google maps. If you need an example of what I need, you can download the app "G-Mon" from the Android Market. I need the same functionality.
