Product Overview

KSW-WNS04 Wireless Channel Emulator (also known as "Wireless Channel Simulator" or "RF Channel Emulator") is a device designed to simulate wireless channel environments, enabling RF channel interconnection and the emulation of dynamic wireless channels.

Equipped with cutting-edge technology in the industry, the wireless channel emulator simulates and reproduces the spatial conditions and noise of complex wireless channels. This enables customers to replicate real-world radio environments in the laboratory, identifying performance issues early in the development cycle. The emulator not only builds upon established leading technologies but also innovatively adopts a fully modular architecture, combining RF front-ends with signal processing units. This design delivers strong scalability and flexibility, comprehensively meeting the testing requirements of next-generation radio equipment in mobile communications, navigation, direction finding, and more.

Depending on different testing needs, the wireless channel emulator supports a wide range of simulation functions, including complex topology networking of multi-point to multi-point RF channels, multipath effects, Doppler frequency shift, fading channel impulse response, dynamic delay, interference signal superposition, signal-to-noise ratio (SNR), and more.
