This is a WiFi analyzer based on Raspberry Pi and a WiFi dongle. After two steps, online scanning and offline analysis, MAC addresses are dropped in Google Map. For security reason, a part of the address is masked but technically any information in iwlist scan can be extracted by modified the offline analysis script.
