The DARPA FCS-C program is developing communications /
networking technologies and notional systems architectures to support
the emerging warfighting concepts for the FCS program. The program's
goal is to demonstrate new enabling technologies supporting real-time
FCS fire control and robotic missions.
Since FCS will require high
data rate and low latency communications to operate in a hostile
electromagnetic environment, such systems should provide robustness to
jamming and significantly improved low probability of detection (LPD)
characteristics. FCS-C could meeting these opposing constraints by
implementing multi-tiered mobile ad-hoc networks utilizing directional
antennas at low-band, and evolving systems such as the
Radio System (JTRS) also using highly directional antennas at
high-band (millimeter-wave frequencies).
