The Joint Network Emulator (JNE) project is used to model and develop a wide array of tactical radio technologies that span the joint services of Army, Navy and Airforce under Project Manager Joint Tactical Networks (PMJTN). This program aims to develop and enhance all joint networking waveforms with common network managers. Scalable Network Technologies first developed the project as the JTRS Network Emulator before the official project expired and the company continued its development of radio technologies with PMJTN.
