Making 5G More Reliable
By Ed Sperling - 08 Sep, 2022 - Comments: 0

The rollout of 5G is a complex and monumental effort involving multiple separate systems that need to function flawlessly together in real-time, making it difficult to determine where problems might arise, or how and when to test for them. Investments in 5G have been underway for the better part of a decade, and the technology is considered the next huge growth opportunity for mobile devices... » read more

The Future Of Wireless Test Is Over The Air
By David Vondran - 08 Sep, 2022 - Comments: 0

The deployment of mmWave technology is synonymous with 5G rollout and the initial results for faster links are amazing. For example, using a mmWave band, the prospects of a 1-2 Gbps link means a typical HD movie can download in less than a minute. An upload link of 30 Mbps also enables the transfer of videos back to the cloud at a record pace. These user experiences are enabled by the antenna l... » read more

Hybrid System-Level Test For RF SiP
By Koji Miyauchi - 08 Jun, 2021 - Comments: 0

In recent years, the proliferation of the IoT has focused attention on low-power-wireless applications. IoT modules incorporating functions such as Bluetooth Low Energy (BLE) transceivers, MCUs, and power-management circuitry are becoming system-in-package (SiP) and even one-chip devices. Such devices increase the demand for a mass-production test environment that can measure them in a short ti... » read more

Testing AiP Modules In High-Volume Production
By Jose Moreira - 11 May, 2021 - Comments: 0

Far-field and radiating near-field are two options for high-volume over-the-air (OTA) testing of antenna-in-package (AiP) modules with automated test equipment (ATE) [1]. In this article, we define an AiP device under test (DUT) and examine the measurement results from both methods. Creating an AiP evaluation vehicle Proper evaluation of an ATE OTA measurement setup requires an AiP module. Us... » read more

5G Brings New Testing Challenges
By Bryon Moyer - 11 Aug, 2020 - Comments: 0

As 5G nears commercial reality, makers of chips and systems that will support 5G will need to take on the standard burden of characterizing and testing their systems to ensure both performance and regulatory adherence. Millimeter-wave (mmWave) and beamforming capabilities present the biggest testing challenges. “5G is expected to have the extended coverage plus the bandwidth to harness ... » read more

Cadence To Buy NI’s AWR Unit For $160M
By Ed Sperling - 02 Dec, 2019 - Comments: 0

Cadence signed a deal to buy National Instruments' AWR business unit for about $160 million in cash, a move that Cadence describes as a way to broaden its market into intelligent system design. AWR's strength is high-frequency RF design automation tools, particularly in the millimeter wave and microwave spectrums, which are critical for radar and 5G. Both of those technologies are expected t... » read more

Gaps In 5G Test
By Kevin Fogarty - 20 Mar, 2019 - Comments: 0

Add one more industry to the long list that analysts expect 5G technology to disrupt—test. While the initial versions of this wireless technology will be little more than a faster version of 4G, concern is growing about exactly how to test the second phase of this technology, which will be based upon millimeter wave. A number of fundamental problems need to be addressed. Among them: T... » read more

Wireless Test Faces New Challenges
By Jeff Dorsch - 09 Apr, 2018 - Comments: 0

Your mobile phone is far more complex than it was even five years ago, and it’s about to become even more complex with new wireless technologies. That has set off a scramble among test equipment vendors to come up with solutions, methodologies and equipment that is affordable, effective and reliable enough to make sure all of this technology works as planned—and that it continues to work th... » read more
