More about RFnest
The RF spectrum environment is constantly changing due to a number of factors. For example, these include terrain and man-made blockages, atmospheric changes, unintentional or intentional interference, the coexistence of civilian/government RF usages, and non-conforming radios. Specifically, RFnest is designed to emulate these RF effects. RFnest enables vendors to achieve critical deadlines on time and within budget by reducing the cost and number of field-tests.
Features & Benefits
The RFnest RF channel emulator allows users to customize and integrate channel emulation into other hardware-in-the-loop emulation environments. It detects trouble spots for simulated mobile routes and suggests suitable locations of base stations considering terrain and RF environment. It combines the following to provide the most complete RF channel-modeling emulation:
RFnest utilizes 3D geometric RF-modeling algorithms, powerful hardware, and easy-to-use software to support both stationary and mobile RF-channel emulation. With an integrated multi-RF record and playback toolkit, users capture and replay snippets or display signals in real-time in two directions. Users generate the desired signal, simulating a source, then record and analyze it through the emulated RF path.
RFview is an integrated GUI-based operations and management (O&M) software tool. For example, it supports the following capabilities:
- integrate control and monitoring of all levels of network performance
- interface with third-party network emulation software including EMANE
- control RFnest hardware to set parameters such as channel impulse response and frequency band
- interface with third party channel modeling tools for additional channel models
Our engineering team continually upgrades RFnest with new features to meet customer needs. In addition to the new D600 series, the existing D500 series continues to be supported.
