Armed forces radiocommunications are vulner-
able to intentional or unintentional eavesdropping
and jamming in today’s communications scenarios.
R&S®SECOS, the secure EPM communications sys-
stem, was developed to counteract such activities.
The EPM method is based on a proven technical
solution.
R&S®SECOS
for R&S®M3xR and
R&S®SDxR radios
R&S®SECOS can be provided with all R&S®M3xR radios
and is available as an option for the new R&S®SDxR radios.
R&S®SECOS can be deployed in secure fixed-frequency
and in frequency hopping mode. It was specifically de-
signed to take advantage of the radios’ technical charac-
teristics and therefore offers a very high range without
compromising transmission quality. R&S®SECOS em-
ploys customized encryption. For voice operation, vari-
ous speech codecs are available that can be selected as
required.
The R&S®SECOS waveform is suitable for use in fast
airborne platforms as well as shipborne and vehicular
applications.
R&S®SECOS allows simultaneous, collision-free opera-
tion of several R&S®SECOS frequency hopping networks
so that multiple orthogonal R&S®SECOS communications
networks can be operated nationwide in parallel without
impacting system performance.
R&S®SECOS supports point-to-point and broadcasting
data transmission and uses forward error correction (FEC).
An integrated time division multiple access (TDMA) meth-
od makes it possible to create tactical data networks. The
multistage TDMA concept enables automatic data ex-
change between different subscribers of an R&S®SECOS
data network. Multiple TDMA data networks can be oper-
ated in parallel.
