The SDR as part of the communications system
The SDR is a secure radiocommunications router
The SDR ensures secure communication with other network nodes inside and outside the platform/command post
The SDR integrates voice and data
Voice (as VoIP) and data are routed in parallel via an integrated network
The SDR can easily be integrated with IP-based intercom, C2-systems, sensors and weapon systems
The SDR connects other network-enabled systems inside the platform/command post to the forces network via IP or legacy interfaces

Waveform
A waveform is the representation of a signal as a plot of amplitude versus time. In JTR System usage, the term waveform is used to describe the entire set of radio functions that occur from the user input to the RF output and vice versa. A JTR System "waveform" is implemented as a re-useable, portable, executable software application that is independent of the JTR System operating system, middleware, and hardware. [JTRS ORD]
