Azimuth Systems, Inc., a provider of comprehensive real world wireless test solutions for 2G/3G/4G, LTE-Advanced and beyond, announced that its new ACE™ MX2 MIMO channel emulator supports advanced testing configurations such as MU-MIMO, InterRAT, and Carrier Aggregation scenarios.
A new forecast published today indicates that multi-mode, multi-band handsets and MIMO will drive staggering growth in the number of RF components shipped for mobile devices. By 2017, annual sales of 3 billion mobile devices will drive almost 20 billion different bands and operating modes.
The CTIA MIMO Expert Forum brought together technologists from ETS-Lindgren, Agilent Technologies, Spirent Communications and EB (Elektrobit) to discuss the challenges of OTA testing. The “Top Ten” questions received from attendees at last year’s CTIA MIMO Expert Forum are answered below.
Extensive efforts are underway to standardize on a next generation platform for performance testing of wireless devices, taking into account LTE, A-GPS, uncertainty budgets and use of head/hand phantoms. This Forum provides an understanding of system performance and presents the core elements - such as the chamber, software and instrumentation - that facilitate systematic and repeatable measurements of MIMO devices. A panel discussion with the speakers from ETS-Lindgren, Agilent Technologies, Spirent, and Elektrobit concludes the Forum.
Madhusudhan Gurumurthy is a Senior Applications Specialist at Spirent Communications. He talked with Microwave Journal about beamforming and TD-LTE systems being deployed in China and across the globe.
Agilent Technologies Inc. announced its participation, with ETS-Lindgren, in an educational panel discussion – “MIMO OTA Measurements: The Next Generation Platform for Wireless Testing” – at the International CTIA Wireless event in New Orleans.
Azimuth Systems Inc. announced the ACE™ MX2 wireless channel emulator together with its comprehensive strategy for real world test. The ACE MX2 MIMO Channel Emulator, Azimuth’s newest channel emulator, is the first product created in support of the new strategy.
Agilent Technologies Inc. announced the availability of a wideband MIMO PXI vector signal analyzer that delivers the industry’s highest-bandwidth signal analysis. The new analyzer enables R&D and test engineers to validate their MIMO 802.11ac designs with a unique combination of accuracy, speed, bandwidth and scalability in a small form factor.
Protocols used by LTE networks to leverage MIMO technologies are significantly impacted by correlation and thus by the channel models under which they’re tested. This Forum provides an understanding of over-the-air, multipath signal challenges, the impact on network performance and considerations for end-to-end testing. A panel discussion with speakers from Anritsu, Rhode &Schwarz, Azimuth and more to be announced will conclude the Forum.
