The white paper, written in collaboration with EB presents the various MIMO test technologies with an in-depth presentation of spatial fading emulation technique, OTA channel models, system calibration and analysis of results.
To meet the increased demand on high data rate applications, new wireless technologies such as LTE, LTE-Advanced, and Mobile WiMAX (Worldwide Interoperability for Microwave Access) require the use of multiple antennas in mobile terminals. Multiple-Input and Multiple-Output (MIMO) technology in a wide sense covers any multi-antenna technology, such as Spatial Multiplexing (SM), Beam Forming (BF), and spatial diversity. MIMO offers significant increases in data throughput, quality of service (QoS) and cell coverage without additional bandwidth or transmit power.
