The purpose of ICS Manager is to assist the Regulation Authorities to handle all these processes.
First of all, ICS Manager provides a database, able to contain all the technical and administrative data related to Spectrum Management, i.e. : • The frequency allocations • The frequency allotments • The frequency assignments • The shared resources : Sites, Antennas, Equipments...

ICS Manager allows to manipulate these data easily, i.e. to : • Display the data in various and adequate ways • Input the data easily • Validate the data (redundancy, consistency, tracability...) • Print maps, notification forms, coordination requests,
customized reports... • Exchange data with other organizations (ITU-R, Foreign
Administrations, Operators,...) • Access the data following a secured privileges policy • Configure the working environment...And eventually, ICS Manager allows to manage all the processes mentioned above...
