Abstract
An interference analyzing system and method analyze interference in a dual mode system having a digital network overlaid on an analog network. The digital network includes portable units operating within digital cell sites; whereas, the analog network includes mobile units operating within analog cell sites. The interference analyzing system measures the amount of interference caused by and to the portable units, and the amount of interference caused by and to the digital cell sites. The system individually compares these interference amounts to a predetermined threshold. If either of the interference amounts exceeds the predetermined threshold, the system selects one of the analog cell sites for spectrum clearing and determines the amount of spectrum to be cleared from the selected analog cell site.
