RKF's award winning modeling and simulation team specializes in the virtual representation of next generation radio access and network layer systems. Our team is adept at rapid prototyping and development of customized modeling software for virtually any application. RKF Engineering develops different types of software simulation tools including:
RKF's design and optimization tools are used to simulate many different propagation and network environments to allow for system optimization. Our tools use advanced coding methodologies to ensure fast execution. Optimization tools, such as genetic algorithms are used to automatically find optimal solutions based on user defined cost functions. For example, RKF developed a satellite system beam placement and optimization design tool that allows engineers to optimize beam laydown patterns based on link constraints, population, customer demographics, coverage area, and rain conditions based on an artificial intelligence engine.
The RKF Engineering team has developed analysis tools in a wide variety of areas to support trade, performance and interference studies. For example, RKF developed simulators to model earth station interference from deployments of radars and multichannel data and video distribution. RKF has also developed traffic, rain and link analysis tools for simulating the performance of satellite air interfaces.
- Data Visualization & Demonstration
Demonstration tools can be used to illustrate complex technologies to potential customers, management or other engineers. Typically these animations are driven by sophisticated computer simulations whose parameters can be dynamically changed during the demonstration. This provides the viewer with an intuitive feel for how the system will eventually operate. Visualization tools aid the design process by providing insight into interrelationships of complex data and a variety of system parameters. RKF offers two and three-dimensional computer animation capabilities to illustrate important concepts.
The figure above on the left illustrates data transmissions across a satellite network. The sliders show on the left allow users to interactively control the simulation. The abstract graphics provide a visualization of the various elements.
- The roadway represents transponder bandwidth
- The blocks represent channels
- The width of the blocks represent channel bandwidth
- The speed of the blocks moving up the roadway indicates relative data rate
- The spacing between blocks represents latency
- The color of the blocks represent the type of data being transmitted
The figure above on the right illustrates the Quality of Service for different location on the earth as a user moves using a satellite handset.
