Equipment used by Project Roll Call
Roll Call is a joint effort by the Federal Communications Commission (FCC) and Department of Homeland Security/Federal Emergency Management Agency (DHS/FEMA). In the wake of a national-level disaster, the effectiveness of first responders and critical infrastructure managers can be hindered by disrupted or destroyed communications systems. Restoring or replacing these systems is a high priority for Federal responders.
At FEMA's request, FCC agents deploy to the disaster area and use Roll Call equipment to examine the radio spectrum and identify disaster-related communications outages. Outages are identified by studying the radio frequency spectrum "Pre-disaster" and "Post-disaster" and comparing those results to each other and to licensee databases to determine which public safety or critical infrastructure systems are unexpectedly off the air. Using this information, FEMA can then assist the public safety/critical infrastructure entities in restoring their vital communications infrastructure. Additionally, Roll Call is also used to identify mass media licensees such as AM, FM and TV broadcast stations that may have been affected in the "Post-Disaster" area. Identifying these licensees is of vital importance to the FCC and FEMA in ensuring that public welfare and evacuation information is disseminated to the disaster area in a timely and accurate manner.
Roll Call is supported by a team of engineers and technical specialists from FCC Headquarters, FCC Enforcement Bureau field offices, and staff at the High Frequency Direction Finding Facility in Columbia, MD.
