RKF develops custom spectrum analysis tools for clients and in-house analyses. These tools aid in the development of spectrum sharing techniques by calculating the amount of potential interference to legacy spectrum users and new users of a particular frequency band. RKF spectrum analysis tools have served many satellite and terrestrial communication companies interested in optimizing the use of their allocated spectrum. These customers have traditionally been concerned with estimating the amount of interference that their receivers will see from newly deployed secondary users of their spectrum or they have been interested in bidding for newly available spectrum.

For example, in recent analyses performed for DirecTV, RKF determined the effect of improperly pointed satellite dishes on the interference received from neighboring satellites. In other analyses for DirecTV, RKF analytically and experimentally verified the amount of interference received from newly deployed Multichannel Video and Data Distribution Service (MVDDS) stations sharing their satellite broadcast band. RKF provides tools and analyses which account for 3D antenna patterns, rain losses, 3D geometries, the operating frequency, as well as other link budget items.

In addition, RKF has a vast amount of experience developing detailed and extensive link budgets and link budget tools for complex systems, such as CISCO's IRIS, TerreStar's TerreStar-1, and DirecTV's satellites. These link budgets include analysis of all end-to-end losses and gains, including ITU models for rain, cloud, gaseous, scintillation, and other attenuations types.
