Should We Even Be Talking About 6G?


Friends and coworkers have been sending me a lot of articles lately about 6G, with snappy headlines that seem to suggest that 5G is already a thing of the past. As a marketing manager working on cellular technology, they want to know what I think. On the one hand, I’m excited to see that the hype surrounding 5G is shining a spotlight on wireless communications research and that visionaries ar... » read more

5G Needs Cohesive Pre- And Post-Silicon Verification


While 5G doesn’t start from a clean slate, it does make significant changes to the 4G architecture. These changes mean that the ecosystem from chips to operators is evolving, giving opportunities to more companies to engage in this growing market. Realignment in fronthaul, midhaul and backhaul In particular, the radio access network (RAN) has been redefined as Cloud RAN (sometimes called ... » read more

High-Performance DSP And Control Processing For Complex 5G Requirements


In the early 2000s, digital signal processors (DSP) were simple in architecture and limited in performance, but complex in programming. However, they evolved to meet of the increased performance requirements of 3G cellular baseband modem applications. A typical 3G modem system would have a single DSP optimized for dual/quad SIMD MAC performance with basic DSP filter instructions like Fast Fouri... » read more

5G OTA Test Not Ready For Production


5G is poised to dominate the wireless world, but over-the-air (OTA) testing of 5G beamforming antennas is still not ready for volume production. Beamforming is a critical element in the millimeter wave version of 5G, because of the limitations of ultra-high-frequency signals. Unlike 4G and its predecessors, millimeter wave technology will not penetrate objects, so signals need to be directed... » read more

Gearing Up For 5G


5G has been touted as the new enabler for many market segments, including mobile phones, automotive, virtual reality, and IoT. But there are many questions and much speculation about when and how this new wireless standard will impact different market segments and what effect it will have on semiconductor design. With a promise of orders of magnitude improvement in communication speed an... » read more

Affordable Design With Wireless Microcontrollers


Today, we are at the peak of technology product availability with the releases of the new iPhone models, Alexa-enabled devices, and more. In the coming days, there will be numerous international consumer OEMs preparing new offerings as we approach the holiday selling season. Along with the smartphones, voice assistant enabled smart speakers and deep learning wireless security cameras, many devi... » read more

Collaboration And Advanced Substrates


Discussions of semiconductor manufacturing tend to focus on CMOS logic and memory devices, sometimes to the exclusion of everything else. Discussions of silicon-on-insulator wafer markets focus on the needs of high performance logic. Lithography analysts emphasize high density memories. It’s easy to forget that real systems contain other devices, too. A modern smartphone probably supports ... » read more

802.11ax: Faster Wireless


Marvell's Sathya Subramanian talks with Semiconductor Engineering about the new 802.11ax wireless standard, how it will work with 5G and existing networks, and how to set up an integrated solution to reduce bottlenecks in the home and in the enterprise. https://youtu.be/KZP59qw6j4Y » 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

5G Gets Closer To Commercialization


Cellular carriers would like to have their new 5G networks up by the end of 2018 or early 2019. One problem: they need a set of standards to create the new technology. In June, tech representatives met and made significant first step for technology companies to start building out the necessary 5G chips and software. In La Jolla, California, the 3rd Generation Partnership Project (3GPP) met f... » read more
