A Radio Frequency (RF) survey records the mobile network and Wi-Fi signals available at a specific location such as a scene, home address or alibi, or along a route relevant to your case. It helps assess whether a device could have connected to a particular cell site at a specific time, providing valuable context in both prosecution and defence cases. TSG combines advanced SDR & SIM equipment with experienced forensic practitioners to deliver court-admissible RF surveys conducted to FSR standards.

RF Survey Data Analysis & Challenge
• Test whether a device could have connected to the cell site at the relevant time
• Assess coverage limitations and areas of overlapping coverage to challenge assumptions
• Identify alternative cell sites a device may have used
• Support or contest attribution claims in joint enterprise, conspiracy, or EncroChat cases
• Assist with pre-charge case reviews, defence strategy, or trial preparation
Exposing Flawed Prosecution Assumptions
RF surveys are a critical part of forensic cell site analysis, offering real-world geolocation data on which mobile signals were actually available at a location. This is especially powerful when prosecution surveys are limited, outdated, or missing altogether. A robust, independently commissioned RF survey can expose weaknesses in the Crown's case, highlight flawed assumptions, and offer credible alternative explanations that can shift the evidential balance in court.
