Qosmotec announced that it would support Azimuth’s portfolio of real world test solutions with the Qosmotec Propagation Effects Replicator (QPER) software. With QPER, Azimuth’s customers will have access to a powerful application that creates virtual environments, which can then be recreated with the dynamic RF fading capability available with the Azimuth ACE MX MIMO Channel Emulator.
Spirent Communications announced that several companies and government research organizations in the Asia Pacific region are using the Spirent VR5 HD Spatial Channel Emulator to test implementations of advanced MIMO beamforming.
When network operators upgrade to LTE they want to take full advantage of their new and existing resources, so to support this objective, Rohde & Schwarz has added MIMO-specific measurements to its R&S ROMES4.65 drive test software. Using this feature, the R&S TSMW network scanner can quickly identify interferers that reduce MIMO performance in LTE networks.
Understanding MIMO OTA Testing: CTIA Wireless MIMO Expert Forum The MIMO Expert Forum at CTIA 2011, provides an understanding of system performance and presents the core elements that facilitate systematic and repeatable performance measurement of MIMO devices. This event is free to all CTIA 2011 Attendees. Presented by ETS-Lindgren, Agilent, Elektrobit, and Spirent. Organized by RF/Microwave Zone and Microwave Journal.
This month, we asked several of our contributing experts to "The Masters of MIMO" August cover story to respond to audience questions from our last webinar on MIMO. Below are the individual replies from repesentatives from SATIMO (Microwave Vision Group) and MI Technologies.
Testing mobile devices involves many phases, including the validation of the devices in the actual field conditions where subscribers will use them. However, field testing in the diverse conditions of terrain, population density, physical location and motion of devices is extremely time-consuming and costly. As the wireless industry works...
Techniques for measuring over-the-air (OTA) performance of wireless devices with single antennas do not work as well for multiple antennas because they assume that the radiation pattern of the device is fixed such that the measured result is a snapshot of the device performance at any given instant in...
This article describes a repeatable reference environment for over-the-air (OTA) testing of multiple input multiple output (MIMO) devices and why the reverberation chamber is uniquely suited to provide insight into MIMO device performance. The importance of reference environments and the characteristics of the reverberation chamber in the context of...
