SEAMCAT - Spectrum Engineering Advanced Monte Carlo Analysis Tool

Introduction to SEAMCAT 

SEAMCAT is a software tool, based on the Monte-Carlo simulation method, which is developed within the frame of the European Conference of Postal and Telecommunication administrations (CEPT).

The tool allows statistical modelling of different radio interference scenarios for performing coexistence studies between wireless systems operating in overlapping or adjacent frequency bands.

The software is maintained by the European Communications Office (ECO) and is distributed free of charge.



Current official version (5.2.0, released on 2 March 2018) 5.2.0 Release note
Current test version      (5.3.0 Alpha 3, released on 8 June 2018)

Installation and system requirements

SEAMCAT is a JAVA application with extension ".jar". Therefore, it is necessary to install the JAVA Runtime Environment (JRE) in your computer to be able to run it. 

In order to ensure an optimal performance on 64-bit computer architectures, please install the 64-bit version of JRE.

You can verify your JAVA version here: https://www.java.com/verify/

The most recent documentation is the online SEAMCAT handbook

A pdf version of the SEAMCAT Handbook was published in April 2016 as ECC Report 252 (51 Mbytes)

The ECO organises SEAMCAT workshops in a regular basis. You will find the latest presentations available in the documentation area of the STG page. 

You can find some practical tips here.


SEAMCAT source code

It is possible to request access to the SEAMCAT source code. More information is available at the SEAMCAT source code page.


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.


SEAMCAT community

There is one e-mail address to report bugs and enhancements and two e-mail reflectors open to administrations, industry and academia. They have different purposes:

You can report bugs or suggest enhancements by clicking here. This directly creates an issue in our issue tracking system, JIRA.

Alternatively, you can send an e-mail to seamcat@eco.cept.org attaching the description of the issue using the STG template

This e-mail reflector 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 SEAMCAT community, etc..). This e-mail is NOT intended to report bugs (see above).You need to register in order to be able to send an e-mail to the reflector:

  • Public STG E-mail reflector

This e-mail reflector is intended for exchanges between active STG members, who contribute to the enhancement of SEAMCAT. When you become a member of the STG Group you are automatically added to the e-mail reflector. You can find more information in the STG page.
