How 5G Affects Test


David Hall, head of semiconductor marketing at National Instruments, talks with Semiconductor Engineering about architectural changes to infrastructure due to the rollout of 5G and how the move from macrocells to small cells is changing test requirements.         Subscribe to Semiconductor Engineering's YouTube Channel here » read more

Challenges Grow For 5G Packages And Modules


The shift to 5G wireless networks is driving a need for new IC packages and modules in smartphones and other systems, but this move is turning out to be harder than it looks. For one thing, the IC packages and RF modules for 5G phones are more complex and expensive than today's devices, and that gap will grow significantly in the second phase of 5G. In addition, 5G devices will require an as... » read more

Gaps In 5G Test


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

System Bits: March 19


Nanomesh material could find use in sustainable applications Imec collaborated with KU Leuven to develop a nanomesh material made of a 3D structure with nanowires. This material could prove to make batteries more energy-efficient, while also improving catalytic converters and fuel cells, and making hydrogen production easier. The research team is touting the 3D nanometer-scale metal grid st... » read more

MIMO And Phased-Array Antennas For 5G


Evolving communication systems are driving developments in the RF/microwave industry. The large umbrella of 5G focuses on supporting three main technologies: enhanced mobile broadband, which is the natural development of long-term evolution (LTE), massive machine-type communications, also known as the industrial internet of things (IIoT), and ultra-reliable, low-latency communications providing... » read more

Issues In Designing 5G Beamforming Antennas


As 5G networking inches closer to reality, one of the more stubborn problems also will be one of the smallest. Several issues have yet to be cracked with beamforming and massive MIMO antennas, which will make millimeter wave (mmWave) spectrum—a key ingredient in 5G networks—work on multiple devices and base-station locations. Millimeter wave is problematic yet promising. Between bands 30... » read more

Will 5G Deployment Lag in the U.S.?


China and other countries are creating “a 5G tsunami” that the U.S. will not be able to match unless it steps up its national investments in 5G cellular communications, Deloitte Consulting warns in a new report. The firm notes that China has outspent the U.S. on wireless communications infrastructure by $57 billion since 2015, constructing 350,000 new sites, compared with less than 2... » read more

Software-Defined Test And Measurement


Software-defined radios, instrumentation and test are ramping up alongside a flood of new technologies related to assisted and autonomous vehicles, 5G, and military/aerospace electronics, breathing new life and significant change into the test and measurement market. Software-defined test adds flexibility in markets where the products and protocols are evolving or still being defined, and wh... » read more

Wireless Test Faces New Challenges


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

System-Level Simulation Of Technologies Supporting Enhanced Spectral Efficiency For 5G New Radio


By Gent Paparisto, Joel Kirshman, and David Vye 5G New Radio (5G NR) is the wireless standard defining the next generation of mobile networks. 5G will offer higher capacity than current 4G, enabling a higher density of mobile broadband users and supporting device-to-device and massive-machine communications. 5G research and development will support lower latency, improved reliability, and... » read more
