used to exchange near real-time (NRT) information. It is a communication, navigation, and identification system that supports information exchange between tactical command, control, communications, computers, and intelligence (C4I) systems. The radio transmission and reception component of TADIL J is the Joint Tactical Information Distribution System (JTIDS) or its successor, the Multifunctional Information Distribution System (MIDS). These high-capacity, ultra high frequency (UHF), line of sight (LOS), frequency-hopping data communications terminals provide secure, jam-resistant voice and digital data exchange. JTIDS/MIDS terminals operate on the principle of time division multiple access (TDMA), wherein time slots are allocated among all TADIL J network participants for the transmission and reception of data. TDMA eliminates the requirement for a net control station (NCS) by providing a nodeless communications network architecture."Simulation Activities using Gateway and Tactical Digital Information Links" http://www.dtic.mil/cgi-bin/GetTRDoc?AD=ADA460117 Other TADILs included TADIL-A, TADIL-B, and TADIL-C, which were known by NATO as
