Roadmap to Capabilities

C4ISR  >  Networked Communications Systems  >  SideHat®

The Exelis SideHat is a simple radio solution that quickly attaches to existing SINCGARS radio installations, offering rapid, affordable and interoperable wideband network communications for Early Infantry Brigade Combat Team (E-IBCT) deployments and other SRW applications.

Using SideHat, mounted and dismounted Soldiers can exchange vital voice and data (including video and position location information) simultaneously in real time. SideHat enables a more accurate picture of the battlefield, fratricide avoidance and battle command on-the-move.
