What about SecurCube® BTS Tracker?
Forensics equipment to measures the radio environment activity, namely the real cell tower (BTS) coverage at the crime scene.
During this examination it is important to take in mind that the spectrum of the BTS provided by telephone operators is theoretical and the cell towers are affected by variables that can change the coverage. Examining all technologies of every carrier it is possible to envisage a trustworthy digital scenario and potential involvement.
BTS information for a focused examination
2G/3G/4G technologies of every telephone operator
Specific BTS scans on demand
Accurate radio sensitivity (i.e. bands, frequencies)
Weak signal identification, unknown entities (i.e. femtocells)
Smart reconstruction of the digital scenario
Trusty reconstruction of the module field test with SecurCube®BTS Tracker Desktop SW
Understandable results available for everybody, experts or non-technical figures
Validity of the findings in courtroom, certified by HASH code
CASE STUDY
The event took place in a suburb area of the town, not equipped with security cameras. No witness noticed the fact.
How can investigators verify a suspect’s alibi according to the testimony?
Investigators are able to start the analysis of the radio environment activity in order to detect cell sites that literally cover the whole area of interest, with conditions most similar to the day of the crime. According to the survey performed and BTS logs examination, they can specifically focus only on the group of cells with interesting parameters in order to understand suspect’s mobile movements and potential involvement. Asking for the traffic phone records (CDR) of these cells, investigators can search for some valuable junctions in terms of time, location and mobile events which happened under coverage of these cell towers.
STEP 1
Field test examination of the environment activity, with the most similar conditions of the day of the crime, to verify the cell sites that cover and can serve the area of interest. It is important to evaluate possible radio environment variables that can affect the theoretical spectrum of the BTS provided by telephone operators.
STEP 2
Desk analysis of the BTS logs performed at the crime scene survey to highlight the serving cell site and reconstruct the reliable digital scenario, such as the possible suspect’s position or way of escape.
STEP 3
According to the survey performed and the consequent analysis of the BTS logs, it is possible to focus just on the group of cells with interesting parameters. Ask the billing records of only the restricted group of cell sites to correlate the digital evidence with SecurCube® PhoneLog.
