Cell Tower Data Analysis

Get a second opinion.

Outdoor coverage estimate for a 2G DCS1800 test cell in the SOMA district of San Francisco. Most of the coverage on this map is on rooftops, not at street level. This coverage estimate was verified with measurements, which were found to be consistent with signal levels on this map. Image by the author. Obviously, this is not a nice, neat circle.

Many of the calls I get from attorneys are requests for the analysis of cellphone records to determine the location of a phone at some given time. The analysis can resolve questions of fact, but lazy thinking and easy answers are giving cell tower data a bad name.
