The Spectrum Management System for Developing Countries (SMS4DC) provides various functionalities for spectrum management activities. Version 5.2 of the software was developed from the contribution of MSIT (Republic of Korea). It contains the revised Article 5 of the Radio Regulations (as per decisions made at WRC- 19), as well as further development on data transfer from other databases to the SMS4DC, such as BR Space IFIC Version 9, and calculations according to the HCM (European cross-border frequency coordination agreement). The SMS4DC also contains monitoring network planning for optimization of spectrum monitoring networks, an interface to the spectrum monitoring software of Rohde & Schwarz and of Thales and a general interface for any other monitoring software (TCI's for example). Self-learning training material can be provided upon request.
The SMS4DC Edition 5.2 on a USB key is currently available for purchase. Please be aware that this version is outdated. A new edition, featuring the latest updates from the WRC, is anticipated by Q3 2024. Current Edition 5.2 subscribers may be eligible for free online access to the new edition on a case-by-case basis.
