A passive GSM interception system with unmatched sensitivity, supporting simultaneous interception of tens of calls. While the rest of the market developed a wideband receiver solution, PICSIX came to an understanding that with a narrowband receiver unmatched sensitivity of -109 dBm could be delivered. The greater sensitivity translates into better ranges, superior call quality and less dropped calls.
