Until now, operational challenges have held back the full adoption of wireless data capability for legacy analog combat network radios: security limitations, flexible digital modem for the kHz bandwidth, and interoperability difficulties between dissimilar systems.

TSI SIGMA™ provides the four critical elements of a comprehensive solution to the combat network radios:

• Integrated GPS for Location Reporting
• Data capability
• Interoperability
• End-to-end security

TSI SIGMA™ is an attachment upgrade to the legacy analog radios. TSI SIGMA™:

• Delivers data capabilities to provide analog radios with true digital capabilities.
• Vastly improves the capacity of mobile wireless devices accommodating new bandwidth-intensive applications, faster current application performance and significant increases in the number of simultaneous users a system can support.
• Promotes complete interoperability between wireless data systems, simplifying information sharing and collaboration.
• Provides security features - end-to-end physical and cyber security - that are unmatched, especially by traditional cellular operators.
• Converges voice and data traffic onto one network, resulting in resource savings and network management efficiencies.
• Integrates GPS technology hence delivering Force Tracking capabilities for the modern force.
