Rohde & Schwarz solution offers complete MIMO measurements for LTE

Rohde & Schwarz
No Comments

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.

Bridging the Gap between MIMO Lab and Field Test Results

Azimuth Systems
No Comments
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...

Creating a Complex Multipath Environment Simulation in an Anechoic Chamber

Michael D. Foegelle, ETS-Lindgren
No Comments
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...
