1.3 Applicability of the SEAMCAT tool to Spectrum Engineering ProblemsSEAMCAT can assist spectrum managers in providing solutions to a number of problems commonly encountered inthe field of spectrum engineering. These include the ability to:identify candidate frequency bands for radio systems;determine the appropriate size of frequency separations (or guard bands);derive transmitter emission masks needed to protect adjacent services;specify receiver susceptibility to preserve system performance in a given radio environment;identify band sharing issues between different services and technologies;help provide band refarming strategies.A number of various radiocommunications systems can be modelled using SEAMCAT, such as:Land Mobile Systems, Short Range Devices and Earth based components of satellite systems;Point‐to‐Point and Point‐to‐Multipoint fixed systems;terrestrial Broadcasting systems and Earth stations of satellite systems.The Monte Carlo technique can address any of the radio interference scenarios regardless of the interfering and victimsystems, for example a population of cellular mobile telephones interfering with a Wireless Local Loop base receiver.There is no restriction upon the victim or interfering systems. The only requirement is that there is knowledge of theparameters which can be used to model them. This includes the receiver and transmitter specifications, thepropagation model associated with the medium of communication and a measure of the quality of service required.Note: SEAMCAT assumes a flat Earth model for calculating path geometries and propagation losses. This limits therange of considered standard interference scenarios to terrestrial configurations and non‐path‐specific propagationmodels.Note: The technical specifications of the receiver and transmitter are commonly extracted from theETSI standard (see http://www.etsi.org/WebSite/Standards/Standard.aspx).25
