Cell Phone Location Data vs. Cell Network Data: Which is More Accurate?

When handling a case where the defendant’s location matters, it is common for law enforcement to provide data in multiple formats such as Call Detail Records (CDRs) labeled TA, CT, Trucall, PCMD, NELOS, Data Sessions, CDR Mediations, and SUB_TIBCO. Additionally, you might receive Cellebrite Reader Reports to supplement this data. Upon opening these spreadsheets, the sheer volume of thousands of data lines can feel overwhelming. Instead of panicking, take a step back and focus on analyzing the data systematically—starting with the most accurate information available.
