We conducted our audit of the Integrated Wireless Network in accordance with Government Auditing Standards. In connection with the audit, and as required by the standards, we reviewed management processes and records to obtain reasonable assurance about the organization’s compliance with laws and regulations that, if not complied with, in our judgment, could have a material effect on IWN.

We audited IWN at the headquarters offices of DOJ, the Joint Program Office, and visited an FBI field office and a FEMA regional office. We performed fieldwork between January and October 2006. We also interviewed the DHS and Treasury CIOs and the Director of the DHS Wireless Management Office. Our audit included an analysis of the strategic and program level management of IWN and a determination of the level of departmental compliance with a federal mandate.

Our audit included examining evidence concerning laws and regulations. The specific laws and regulations we reviewed included the Telecommunications Authorization Act of 1992 and the NTIA Narrowband Mandate of 1993.

While performing our audit, we determined that DOJ is not in compliance with the NTIA Narrowband Mandate of 1993. DOJ is aware of this non-compliance issue and its consequences as discussed beginning on page 33 of this report.

With respect to areas that were not tested, nothing came to our attention that caused us to believe that DOJ was not in compliance with the laws and regulations cited above.
