Adesirable interface between multiagents is through over-the-air RF connections that include not only the intended direct RF communications paths but also highly variable multiray propagation, range attenuation, external RF influences, and near-earth influence. These influences are all difficult to predict, control, and repeat in an outdoor environment. This outdoor testing, as has traditionally been done, is extremely expensive while simultaneously providing fewer data points than more controlled events and the testing events are generally not repeatable.

Currently, in certain types of antenna design fields, the correlation between model and simulations (M&S), hardware-in-the-loop (HITL) testing, and open-air range (OAR) testing is minimal. Open-air test ranges introduce many uncontrolled variables that not only affect the perfor mance of an RF communications system but also impact the quality of the test data.
