[Short Range Communication Wireless Channel and Changeself Prism Channel Emulator]

The wireless channel environment of short-range communication (such as WiFi, Bluetooth, etc.) is characterized by a relatively short communication distance , generally a few meters to tens of meters, the channel simulation mainly considers the basic multipath channel simulation under the condition of lossless delay, so that the simulated channel delay and multipath characteristics are as close as possible to the wireless channel environment of the actual short-distance communication, and then realize More realistic and reliable wireless channel simulation for short-range communications.

Short-range communication systems include a lot, such as: WIFI, Bluetooth, UWB, etc. In the short-distance communication system, the interference and damage of the main channel caused by the spatial multipath interference is very large, especially the short-range multipath, which requires optimization of the channel, including algorithm and anti-interference optimization. Changeself Prism can simulate the optimization in the optimization. The underlying channel environment of space.

The Prism channel emulator is designed for spatial channel emulation of short-range communications, ultra-low latency for short-range communications , fading, multipath characteristic design, infinitely close to the actual simulation of short-distance communication, and can verify performance problems in the early stage of product development.

For short-range channel emulators, the most important factor to highlight short-range is that the processing delay of the instrument itself cannot be greater than The distance delay that needs to be simulated, the basic signal of most simulators on the market The processing delay is 1.9μs above, but for WIFI and Bluetooth applications, usually within a range of tens of meters, the signal spatial transmission delay at150ns , the basic processing delay is far beyond the distance that needs to be simulated and cannot be compensated.

Prism It belongs to a modular architecture, which consists of a pluggable RF front-end and a core signal processing system. span>consistency, repeatability, precise fading, distance Mock, wearVery useful for wall simulation , which overrides 500MHz—6GHz is the most cost-effective basic spatial channel emulator in the industry, allowing you to build flexible test scenarios in the laboratory, and it is also the most cost-effective basic spatial channel emulator in the industry. Creation of a real short-range channel scenenew product.
