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

Looking To Unlicensed Spectrum For 5G


When the International Telecom Union (ITU) outlined the key objectives for 5G, the 3GPP faced the difficult task of expanding the capabilities of the current wireless network under the constraint of limited spectrum. Spectrum equates to bandwidth, and the industry needs more spectrum to increase data rates and address specific use cases beyond 4G. Unfortunately, there isn’t much unoccupied sp... » read more

On The Cusp Of 5G


Carriers and chipmakers are celebrating the rollout of the first standards-compliant commercial 5G services. "We are, officially in the era of 5G," said John Smee, vice president of engineering at Qualcomm at the recent 5G Summit at IEEE's International Microwave Symposium (IMS) in Boston. Movement is happening on the commercial end. Major U.S. carriers Verizon, AT&T and Sprint have set ... » read more

GaN Versus Silicon For 5G


The global race to launch 5G mmWave frequencies could provide a long-anticipated market opportunity for gallium nitride (GaN) as an alternative to silicon. GaN is more power-efficient than silicon for 5G RF. In fact, GaN has been the heir apparent to silicon in 5G power amplifiers for years, especially when it comes to mmWave 5G networks. What makes it so attractive is its ability to efficie... » 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

Edge Complexity To Grow For 5G


Edge computing is becoming as critical to the success of 5G as millimeter-wave technology will be to the success of the edge. In fact, it increasingly looks as if neither will succeed without the other. 5G networks won’t be able to meet 3GPP’s 4-millisecond-latency rule without some layer to deliver the data, run the applications and broker the complexities of multi-tier Internet apps ac... » read more

Antenna Array Design for ADAS


By Milton Lien and David Vye By implementing radar technology over the 76 to 81 GHz spectrum, advanced driver-assist systems (ADAS) enable smart vehicles with the ability to alert and assist drivers in a variety of functions, from low tire-pressure warning to collision avoidance to self-parking. These automotive radar applications use the millimeter-wave (mmWave) spectrum to exploit more ban... » read more

Psst, Says 5G… Wanna See What My New Antenna Tech Challenge Looks Like?


5G offers incredible potential, enabling 1000X more traffic, 10X faster speeds and an increase in the device battery capacity by 10X! So why hasn’t 5G technology been rolled out yet? The benefits all sound great, but there are also some challenges that need to be addressed. 5G is destined to cause a revolution around the world with burgeoning industries like autonomous driving, internet of... » read more

Optimizing 5G With AI At The Edge


AI touches our lives in many different ways, and while some AI-enabled applications are highly visible, like the increasingly popular Amazon Echo and Google Home voice-controlled intelligent digital assistants, others are less obvious. But by no means are they less important. For example, AI techniques are essential to the successful rollout of 5G wireless communications. 5G is the develop... » read more

Manufacturing Bits: Feb. 6


GaN trusted foundry HRL Laboratories--an R&D venture between Boeing and General Motors--has launched a new foundry service for use in advanced millimeter-wave (mmWave) gallium-nitride (GaN) technology applications. HRL’s process, called T3-GaN, is a high-electron-mobility transistor technology. It will enable the fabrication of GaN-based monolithic microwave integrated circuits (MMICs... » read more
