Dominic Perez, Chief Technical Officer at Curtiss-Wright Defense Solutions and Jeff Smith, Vice President of Engineering, REDCOM Laboratories join John Keller, Chief Editor of Military and Aerospace Electronics to discuss solutions to interoperability challenges that involve REDCOM Sigma, standards-based Command and Control software that helps integrate legacy and future infrastructure. Sigma provides voice and radio over internet, video chat conferencing and transcoding and push-to-talk console capability. Sigma supports multiple deployment options and the webinar will discuss how to choose the correct hardware for land, sea and air with examples from Curtiss-Wright's modular and rugged tactical communication systems. This level of interoperability will give war fighters the best chance of maintaining critical Command and Control communications across joint and coalition forces in a contested environment.
