Massive IoT Interop Fuels Protocol Battle


Wireless standards are plentiful, but most are not capable of being scaled to the level of a smart city. As a result, such networks have been built application-by-application using proprietary stacks, often with non-interoperable network layers. That, in turn, has slowed the proliferation of dense wireless connectivity at scale. “In a hyper-connected world, connectivity choices are driv... » read more

Getting Ready For An Efficient Shift To PCI Express 6.0 Designs With Optimized IP


PCI Express (PCIe) 6.0 technology with key changes will bring about challenges that high-performance computing, artificial intelligence, and storage system-on-chip (SoC) designers will face. This article provides designers a summary of the major changes and how they can be handled to ensure a smooth and successful transition to PCIe 6.0. The three major changes in PCIe 6.0 that designers nee... » read more

The Quest To Make 5G Systems Reliable


Semiconductor Engineering sat down to discuss 5G reliability with Anthony Lord, director of RF product marketing at FormFactor; Noam Brousard, system vice president at proteanTecs; Andre van de Geijn, business development manager at yieldHUB; and David Hall, head of semiconductor marketing at National Instruments. What follows are excerpts of that conversation. SE: How do we measure the reli... » read more

Efficient Sensitivity-Aware Assessment Of High-Speed Links Using PCE And Implications For COM


This technical white paper, originally presented at DesignCon, investigates the challenges of increased data rates and reduced margins in high-speed link design. Section 1: Introduction Section 2: State of the Art Link Evaluation and Assessment of Parameter Variability Section 3: Proposed Modeling Framework Section 4: Sensitivity Analysis of a High-Speed Interconnect Section 5: Conclusio... » read more

Beyond-Line-Of-Sight Troposcatter Communications Primer


Though tropospheric scatter (troposcatter, or tropo) communications technology has existed since the 1950s and was used by the U.S. military from 1960 to 2002, this legacy technology is being revitalized in the wake of concerns around the reliability of tactical satellite communications (Satcom). For several decades, satellites were a reliable and secure method of communications that provided s... » read more

Optimizing Embedded Narrowband IoT Modem Solutions To Meet IoT Connectivity Challenges


As the concept of the internet-of-things (IoT) was taking shape, the communications industry started addressing the anticipated need to connect these “billions of IoT devices” (Figure 1). Since these devices are meant to address low-cost, low-power (battery operated) applications, cellular technology trends to increase bandwidth – driven largely by mobile phones – needed to be revisite... » read more

Power-Hungry Safety And Security


There is a price to pay for everything. When it comes to adding safety and security into a device, the costs in terms of power and area can be significant, but if the task is taken seriously, those costs can be managed and minimized. New analysis and implementation tools are coming to market that can also help to keep the costs contained. But it also requires the right mindset. As more indus... » read more

More Rare Earth Rumblings


It’s time to look at the market for rare earths again. Rare earths are chemical elements found in the Earth’s crust. These elements, which are critical, are used in cars, consumer electronics, computers, communications, clean energy and defense systems. So why worry about them? China produces and controls 80% of the world’s rare earths. Other nations depend on China for these materi... » read more

High-Speed Communications: On The Road Again


Lately, we’ve had quite a lot of trade show participation. I discussed ISSCC last month. I will be careful right now to state that ISSCC is a technical conference and not a trade show. The organizers are quite particular about that. Nonetheless, we were invited to demonstrate our high-speed SerDes there, and we got a lot of great questions from a lot of very smart people. Since ISSCC, we... » read more

System Bits: March 26


Swear to tell the truth Lots of lies are told on the Internet. Shuyuan Ho of Florida State University wants to unveil those falsehoods with an online polygraph. “The future of my research is an online polygraph that could be used many different ways,” said Ho, an associate professor in the College of Communication and Information. “You could use it for online dating, Facebook, Twitter... » read more
