Simplify Dynamic Frequency Selection (DFS) Radar Profile Creation
Keysight Technologies, Inc. Signal Studio software is a flexible suite of signal-creation tools that will reduce the time you spend on signal simulation. For DFS radar profiles, Signal Studio’s performance-optimized reference signals—validated by Keysight—enhance the characterization and verification of your devices. Through its applicationspecific user-interface you’ll create standards-based and custom radar signals for DFS tests.
Dynamic frequency selection (DFS) test
Dynamic Frequency Selection (DFS) Overview
Unlicensed devices, typically WLAN/WiMax™, are being allowed to operate in the same frequency spectrum that is currently allocated to licensed devices, typically radar systems (mainly for military & weather). Radar systems are guaranteed to have spectrum protection. Therefore, unlicensed devices must not transmit on the same frequency upon which a nearby radar system is operating. They must instead choose an operating channel that covers a frequency range not currently utilized by a nearby operational radar. This choice is made dynamically during operation, and is called Dynamic Frequency Selection (DFS). Currently DFS is mainly defined in U-NII band, which is used primarily for WLAN systems, including three frequency bands: 5.150 to 5.350 GHz, 5.470 to 5.725 GHz, and 5.735 to 5.915 GHz. DFS tests typically define the radar profiles which describe the RF and time domain characteristics of a given radar signal type. The radar profiles are defined by various government communication agencies including FCC, ETSI Japan MIC, Korea and China DFS standard.
