Title: Test of an experimental SATCOM network in EHF band

In 2008, the French MoD has started an experimental SATCOM network which aims at using EHF resources (44/21 GHz) in an efficient manner. It will lead to an operational use of this frequency band in order to cope with the lack of SHF frequency resources. Contrary to the SHF concept of use where links are planned with constant data rates and static margins, the EHF band requires the use of fading mitigation Techniques to adapt to transmission conditions. The EHF experiment consists of two networks: - the first one is based on DVB-S2/DVB-RCS (digital video broadcasting satellite 2)/(digital video broadcasting-return channel satellite) standards, the second one uses a frequency hopping electronic protected modem (EPM). The aim of the experiment is to: assess solutions based on COTS (components on the shelf (DVB-S2/DVB-RCS) and EPM test and define EHF terminals, define and to test services offer in EHF.
