Wireless Testing and Channel Emulation

What are the Key Channel Emulation Issues?

Wireless communication is a demanding application that requires complex air interface protocols to seamlessly interact and mitigate harsh radio channel effects. When a wireless signal is sent from the transmitter to the receiver it traverses a complex radio channel that distorts the intended signal transmission. The radio propagation effects can be characterized by fast fading or multi-path fading, relative path delay, relative path loss, and slow shadow fading or log-normal fading. Different mobile environments generate various combinations of these effects.

Spirent Solves Your Critical Test Challenges.

Spirent offers an industry-leading multi-path fading test platform. Accurate fading emulation of complex wideband wireless channel characteristics allows thorough testing of wireless devices such as access points, handsets, base stations, and other wireless devices. Wireless fader test standards across the industry call for performance metrics under various conditions. Spirent's solution offers pre-defined test cases to meet these specifications, and the flexibility to create custom real-world fading scenarios.
