RKF creates simulations and models of wireless communications systems. In our work with satellite systems, we have used simulations to support the conceptualization, design, and development of satellite communications payloads with on-board digital processing as well as conventional bent-pipe designs. This work includes systems in all orbits (LEO, MEO, HEO, GEO) and all operating bandwidths (S-band, L-band, C-band, Ku-band, Ka-band). In our work simulating terrestrial systems, we have developed LTE, Wi-Fi, and 5G models, and traffic, and clutter models to create highly-realistic dynamic simulations of systems utilizing these technologies. Additionally, RKF EMI modeling can perform interference analysis of electromagnetic environments modeled in accordance with a wide variety of propagation models to account for intermodulation as well as co-channel, adjacent-channel, and harmonic interactions. These interference analyses are used to assure compliance to coordination and spectral sharing agreements and provide spectrum managers with situational awareness across their communications systems. 

We develop models and simulations at many levels of granularity to adequately predict a system’s performance before it has been deployed or even built. For individual system components, such as antennas, amplifiers, filters, and processors, we develop custom models to capture component-specific behavior. For end-to-end systems, we chain together these models and incorporate wireless propagation models along with link budget analyses to accurately determine the system’s overall performance. For simulations of large-scale deployment of systems in both terrestrial and space settings, we develop clutter and traffic models and perform interference studies to ensure that the system is capable of performing up to the client’s desired specifications at scale in a realistic environment.
