Overview

This overview includes steps and an example of how to geo-locate a Raspberry PI device. Similar steps can be utilized to locate any other IoT or mobile device that can send Wi-Fi scan events of nearby access points (APs), cellular, and GPS information.The location information can be utilized for locating, tracking and managing devices or resources, geo-fencing and other geolocation use cases.

Location Process

• The device collects information from all of the Wi-Fi Access Points (APs), cellular, and GPS sources.
  • Information collected includes SSID, MAC Address and Signal Strength.
  • Communication with the APs is not required
  • Devices in urban areas typically receive greater than 40 APs 
• The requesting cloud application, using Skyhook/TruePosition's Location API, passes the collected information to TrueFix cloud servers.
• TrueFix calculates the possible location of the device based on the scan information provided.
  • Wi-Fi access points utlize the crowd-sourced database.
  • The crowd-sourced database can be cloud-based or be on-premise.
• TrueFix returns the device location back to the device and requesting cloud application
