In-depth look at several trends in wireless testing during the evolution of mobile technology from 2G to 4G and beyond

Details the complete workflow of an antenna design for the LTE mobile phone applications, starting from the antenna design to the bit rate channel capacity calculations

Details how system simulation will help understand the design performance and requirements needed to achieve transmitter system-level metrics

The Centre for Wireless Communications (CWC), a project-funded research group operating in conjunction with the Department of Communications Engineering at the University of Oulu, Finland, is employing EB Propsim F8 radio channel emulator and EB MIMO OTA Application to provide wireless testing and research capabilities under the most realistic propagation conditions.

Anritsu Co. and ETS-Lindgren announced the Anritsu MT8820C RF Tester has been selected by ETS-Lindgren as an approved test solution for 2G to 4G/LTE/MIMO Over-the-Air (OTA) testing. As part of the selection, support for the MT8820C has been integrated into the CTIA-compliant ETS-Lindgren EMQuest™ EMQ-100 Antenna Measurement Software.

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.

Introduction to MIMO beamforming in TD-LTE networks highlighting current challenges and an effective test solution

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.
