5989-3443ENAgilent MIMO Wireless LAN PHY Layer [RF] Operation & MeasurementApplication Note 1509IntroductionThis application note is written for people who need an understanding of MIMO radio operation as it applies to WLAN, and the test configurations for multi-channel radios. Increasing use of wireless systems and new applications like digital video streaming mean a continued desire for higher throughput or better coverage from radio systems. To some extent, the use of more complex modulation formats such as Orthogonal Frequency Division Multiplexing (OFDM) and 64 QAM has satisfied this need, but further advances are being made. Changing the use of the spectrum available is being pursued in several ways. Ultra-Wideband (UWB) is one approach for increasing throughput; another is called Multi-In……
