Wireless Location Forensic Analysis
ZK Services has over 35 years of experience in cell phone
and wireless technology and location data collection and
analysis. We use a proprietary interface to cell phone
chipsets, Wi-Fi adapters, Bluetooth dongles, etc. We collect
hundreds of measurement parameters that can be used to
determine location within a high degree of resolution.
Messaging, location and other relevant data can be
extracted from the mobile phones. CDR and Call Trace
records are obtained from the wireless network providers and
compared with actual test data in order to determine exact
location. Location can be determined for outdoor as well as
indoor venues. Wi-Fi, Bluetooth and other wireless data can
be combined with cellular data in order to enhance the
resolution further, in some cases determining the exact floor
and location within a building. Download the article to find

Truck or Vehicle GPS Tracking
Data from the GPS tracking systems on commercial vehicles can be used for identifying the path and time
driven. Typically, because the data is in raw form when received from the GPS unit, an expert must be used to
interpret it. This typically includes having the expert show, on maps and photos, the location information from the
GPS system. In addition, the expert will be needed to describe the GPS system, its accuracy and any other
information necessary to show its relevancy to the issue at hand.
