Overview:
Over-the-air (OTA) measurements are commonly used
to determine the wireless system performance of wireless-enabled devices aside
from field testing. LTE has introduced MIMO in order to improve network
performance. This webinar presents a straightforward and cost-effective solution
for LTE MIMO OTA testing to rank radiated MIMO performance. The LTE MIMO OTA
decomposition approach determines separate figures of merit for the key MIMO
receiver chain subsystems: the MIMO antenna subsystem using the radiated
approach and the MIMO receiver using the conducted approach. The webinar focuses
on the radiated approach, which takes arbitrary angles of arrival (AoAs) for the
MIMO streams into account and provides sufficient control over the AoAs in 3D.

Attendees will learn:

  • LTE MIMO OTA test methodologies
  • Decomposition approach
  • OTA measurements of 2×2 MIMO LTE devices

  • Research and principal engineers
  • RF and transceiver design engineers
  • Test engineers and managers
  • OTA engineers
  • Wireless system engineers
