Appendix VIII
FBI Ad Hoc Solutions


When technologies are not covered by CALEA, or when a covered technology is not CALEA-compliant, the FBI works to develop an “ad hoc solution” to allow law enforcement to conduct the electronic surveillance it needs. The FBI provided us with some examples:

  • System DCS-3000. The FBI has spent nearly $10 million on this system. The FBI developed the system as an interim solution to intercept personal communications services delivered via emerging digital technologies used by wireless carriers in advance of any CALEA solutions being deployed. Law enforcement continues to utilize this technology as carriers continue to introduce new features and services.
