The TENA Middleware is the high-performance, realtime, low-latency communication infrastructure used by range resource applications and tools during the execution of a range event. All data exchange and control commands between range systems are accomplished by the TENA Middleware, which provides system developers with a unified Application Programmers Interface (API) to support the real-time exchange of software objects, messages, and data streams (audio, video, telemetry, or tactical data links).
