Cell Tower Analysis & GPS Location Mapping

Location evidence can help establish timelines and provide insight into where a device may have been during events relevant to a legal matter or investigation. CAER analyzes cellular provider records, cell tower information, GPS data, and other available location evidence to help clients understand and present complex location information.

Location Evidence We Analyze

The specific analysis depends on the records and data available. Relevant sources may include:

  • Call detail records and related cellular provider records supplied for analysis
  • Cell site and sector information
  • Historical cell site usage and handoff patterns
  • GPS and device location information when available
  • Location information contained in mobile device extractions
  • Movement patterns and travel timelines
  • Maps and visualizations designed to explain the available location evidence

Understanding Cell Tower Evidence

Cellular-provider records can be highly useful, but they must be interpreted carefully and within their technical limitations.

  • Cell tower records generally require careful interpretation and should not be treated as precise GPS coordinates
  • The usefulness of the analysis depends on the records available, the provider, the time period, and the surrounding circumstances
  • CAER can assist counsel with understanding what provider records may be relevant and with drafting legal process language designed to request appropriate records
  • Once records are produced, CAER can analyze and visualize the data for the matter

How Location Analysis Can Help

When appropriate data is available, location analysis may help counsel or investigators:

  • Develop timelines from available location evidence
  • Compare device location information with known events
  • Identify movement and travel patterns
  • Create maps and visual presentations for consultation or litigation
  • Explain the limitations and significance of the location evidence
