American Action Forum Report Urges More Use of Probabilistic Interference Tools
Increased spectrum congestion shows the need for the FCC to put more emphasis on the use of probabilistic interference assessments, said Jeffrey Westling, American Action Forum technology and innovation policy director, in a report. Traditional spectrum management decisions “were based…

on impact estimates using deterministic, single-value calculations that employ worst-case scenarios,” he said Monday: “This approach results in an overly conservative management regime that often prevents the deployment of new services even if the likelihood of harmful interference, and the potential impact if harmful interference did occur, remained relatively insignificant.” Probabilistic interference assessments “better account for the actual operating parameters in the field, as well as the actual impact the interference will have on operations,” he said. They “provide regulators with a more complete picture of the radio environment when determining whether new services can be deployed and operate, allowing for increased spectrum efficiency in the United States.”
