Anite signed an agreement to develop advanced multiple-input/multiple-output over-the-air testing approaches with China Telecommunication Technology Labs-Terminals, which is overseen by the China Academy of Telecommunication Research. Anite’s Propsim channel emulators are set to be used for developing MIMO OTA testing to help device original equipment manufacturers and mobile operators examine the actual performance of future mobile devices, without the use of either an anechoic or reverberation chamber – the two hotly debated methods that are typically used in OTA testing.
For more insight on OTA testing, check out this panel from last year’s LTE Innovation Summit.
The agreement covers development of MIMO OTA test methodologies for carrier aggregation, 3D MIMO, virtual MIMO OTA drive testing, MIMO OTA testing of handovers and interference, and device-to-device testing.
• JDSU said that Softbank Mobile will be using its AriesoGeo platform that ties in location data with network intelligence in order to improve quality of experience; the technology is going to be implemented in Softbank Mobile’s 3G and LTE networks in downtown Tokyo.
JDSU launched its Certifier 10G for testing copper up to Category 6A, which is positioned as an early level tester that comes preconfigured with copper cabling specs from the major manufacturers to get testing done quickly, without additional complexities in the equipment by having support for fiber or Class FA.
JDSU also added some features to its T-BERD/MTS metro Ethernet test suite for more network performance visibility, including the ability to perform a traffic-shaping test that will provide insight for coaching end users on getting traffic-shaping settings right on their edge routers, and providing latency measurements within 100 nanoseconds of accuracy.
• Cobham gave an update on the integration of distributed antenna system provider Axell Wireless with test company Aeroflex – the two companies will be combined to form Cobham Wireless, and the integration is expected to be complete by July.
Cobham’s wireless segment will be led by SVP Ian Langley.
• Tektronix said that a newly added option for its 100G optical sampling module used in conjunction with its DSA8300 Digital Serial Analyzer sampling oscilloscopes results in a configuration that is “the first and only test solution with signal sensitivity sufficient to test optical devices and perform clock recovery required by the recently approved 100GBASE-SR4 (IEEE 802.3bm) specification.”
The new Clock Recovery Trigger Pickoff option, used with Tektronix’s 80C15 optical sampling module, is designed to give optical signal analysis for both single-mode and multimode optics and the ability to measure signals as low as -9 dBm.
“Tektronix continues to work closely with standards bodies across the technology landscape to ensure that we are delivering the right test solutions at the right time,” said Brian Reich, GM for performance oscilloscopes. “At the same time, we have embraced the need to minimize noise in the signal path to give our customers complete confidence in measurement results. As demonstrated by this latest introduction, we are the clear leader in providing solutions with the highest sensitivity and lowest noise in the industry today.”
• Keysight Technologies has launched a new tunable laser source for spectral loss measurements; continuous stream measurements for its U5303A 12-bit PCIe digitizer; and a software analysis option for its 89600 VSA software for the Data Over Cable Service Interface Specification 3.1 spec, a.k.a. DOCSIS 3.1.
Keysight also announced a collaboration with Tohoku University’s Center for Innovative Integrated Electronic Systems for testing devices used in extremely low-power electronic systems, as part of an overall effort to move toward lower carbon emissions by reducing the power used in electronic appliances.
