What is SEAMCAT?

SEAMCAT® is a software tool based on the Monte-Carlo simulation method, which was developed within the frame of European Conference of Postal and Telecommunication administrations (CEPT). This tool permits statistical modelling of different radio interference scenarios for performing sharing and compatibility studies between radiocommunications systems in the same or adjacent frequency bands.

        SEAMCAT Stakeholders

        The SEAMCAT project is an ongoing WGSE (Working Group Spectrum Engineering) activity. The daily maintenance of the project and the SEAMCAT software is entrusted to the ECO. STG (SEAMCAT Technical Group) acts as the supervising committee and source of technical expertise.

        There exists 2 mailing reflectors open to administration, industry and academia:

        • Public SEAMCAT E-mail reflector

          • This email list allows to disseminate useful information within the group of SEAMCAT users (i.e. user support messages, usage tips, information on updates and questions/answers from members of the group, etc..).

        • Public STG E-mail reflector 

          • This email list is not just for users, but people who want to develop and contribute to the insides of SEAMCAT.

        Free JAVA development of the SEAMCAT source code is possible.
