Check and Measurement: R&S touts 5G mmWave angle-of-arrival testing


Rohde & Schwarz says it’s the first take a look at firm with an over-the-air take a look at system that’s CTIA-authorized for a number of angles-of-arrival (AoA) testing, which is a crucial side of 5G gadget efficiency in millimeter-wave bands.

R&S mentioned that testing a number of angles of arrival is “essential for verifying the efficiency of cell gadgets within the mmWave area, as radio waves at these excessive frequencies … endure from excessive path loss and subsequently have to be centered in slim beams which are difficult to seek out, observe and hand over whereas transferring.”

The take a look at system that may obtain any such testing consists of the corporate’s R&S TS8980 conformance take a look at system, plus its R&S CMX500 5G tester and its R&S ATS1800M mmWave (FR2) over-the-air testing chamber.

In different take a look at information:

UL Options says it has acquired U.Okay. agency Cimteq, which focuses on design and manufacturing software program for wire and cable producers. Monetary phrases of the transaction weren’t disclosed, however the deal closed September 9.

“Rising applied sciences inside sensible cities, Trade 4.0, mobility and communications industries all depend on wire and cable to function the supply spine for brand new service choices,” mentioned Jennifer Scanlon, president and CEO of UL Options. “We’re assured the acquisition of Cimteq permits us to assist wire and cable clients proceed to evolve and succeed as these applied sciences introduce new challenges and alternatives.”

Cimteq is predicated in Wrexham, Wales and was based in 1998; it had personal fairness backing from Foresight Group.

Keysight Applied sciences has a new MIPI compliance take a look at resolution for automotive serializer/deserializer receivers, developed in partnership with BitifEye Digital Check Options and Wilder Applied sciences with assist from Valens Semiconductor. Keysight mentioned that the answer helps implementations of MIPI A-PHY, a long-reach bodily layer interface for automotive purposes and others that rely on a surround-sensor surroundings similar to cameras and in-vehicle infotainment shows.

Keysight additionally this week launched the newest model of its flagship Pathwave Superior Design System software program for high-speed digital (HSD) design; the corporate highlighted enhancements to its reminiscence design options for the Double Knowledge Fee 5 (DDR5) interface normal.

Rohde & Schwarz additionally mentioned this week that its R&S ATS1500C antenna take a look at system has a brand new temperature take a look at possibility with the flexibility to check in a variety from -40 °C to +85 °C, in addition to a brand new feed antenna that helps parallel entry to each polarizations.

-Analyst agency International Trade Analysts estimates that the worldwide marketplace for wi-fi take a look at tools can be about $5.8 billion this 12 months and can attain $7.7 billion by 2026, reflecting a compound annual progress fee of 6.9%. In a July 2022 report, the agency mentioned that the wi-fi infrastructure take a look at tools section of the market will develop barely sooner than the market general, at 8.4% CAGR, to hit $4.9 billion by 2026.

Ericsson is working with the Aerial Experimentation and Analysis Platform for Superior Wi-fi (AERPAW), funded by the Nationwide Science Basis and a consortium of business companions, to discover the usage of 5G drone operations for sensible agriculture purposes. Full story right here.
