Testing the Big Bang of Smart Devices

Thanks to the proliferation of smart devices in the Internet of Things (IoT), it’s a circumstance not unlike the overwhelming sense of wonder and bewilderment that ancient Greek astronomer Ptolemy must have felt when gazing up at a sky full of stars on a clear winter’s night, trying to rationalize the vast tableau before him. But just as we wouldn’t critique early astronomers and philo... » read more

Power/Performance Bits: April 19

Ferroelectric non-volatile memory Scientists from the Moscow Institute of Physics and Technology (MIPT), the University of Nebraska, and the University of Lausanne in Switzerland succeeded in growing ultra-thin (2.5-nanometer) ferroelectric films based on hafnium oxide that could potentially be used to develop non-volatile memory elements called ferroelectric tunnel junctions. The film was g... » read more

Interference In The Car

Once again, a paradigm shift is upon us. Mobile connectivity has radically changed the automobile’s place in the world of connected everything. And that paradigm will shift even further once the IoE is in full bloom. As all of this unfolds and technology marches on, some see the connectivity of the automobile as being a better and more powerful alternative to the smartphone. It is touted a... » read more

Developing Effective Design Strategies for Today’s Wearable Devices: Power Management

As the next wave of wearable devices expands into a new class of revolutionary and innovative products, there will be a growing importance placed on the real-time operating system (RTOS) and corresponding middleware. Wearable System-on-Chip (SoC) processors require an operating system optimized for size and performance with power-efficient wireless connectivity options needed for machine-to-mac... » read more

Inside Mesh Networks

Mesh networks could revolutionize communications in the future. Independent of the Internet we know today, wireless mesh networks (WMN) allow both ad-hoc and fixed wireless “nodes” to form a communications net that can become a very powerful information sharing hub. The idea is that all devices, both user-controlled and autonomous, would be open to act as relay points for the transmissio... » read more

The Rise Of Dynamic Networks

The Internet of the future, and particularly the [getkc id="260" comment="Internet of Everything"], will be interlaced with millions if not billions of intelligent, dynamic, self-organizing networks. These networks will be full of elements that are capable of autonomic self-registration across these multitudes of networks. It is one thing to put up a security perimeter when you know who the... » read more

A Primer For The 802.XX Physical Layer

This is the second installment of the 802.XX for the IoE series of articles. The first one was published in the August issue and addressed the Media Access Control (MAC) layer. In this article, we will examine the elements of the physical (PHY) layer of the 802.11 protocol stack. For reference, the protocol stack is shown in figure 1. The best designs, like everything else, are built on a so... » read more

802.XX And The IoE

Ever since the first 802.11 standard was published in 1997, it has evolved to become the de facto protocol for much of the wireless networking across a wide range of devices and implementations. Today the protocol family includes 802.b 802.11a, 802.11g, 802.11n, and 802.11ac, respectively. Some of these will play a very important role in the IoE. There are other 802.xx protocols (such as 802.15... » read more

Smart Grids, Smart Cities

What makes today’s power grid “intelligent” is the modernization of the technologies that both provide and support power distribution. These technologies use intelligent data analysis and communications, via a two-way, automated communications network to analyze what is going on within the grid. Information about the activities of both suppliers and consumers is collected, analyzed, an... » read more

Wireless Technologies For The IoE

It's generally understood the [getkc id="76" kc_name="Internet of Everything"] eventually will be the interconnect platform of all things, wireless and wireline. The utopian scenario is to have a common platform, with standardized protocols, which everyone builds to. Will that happen? Perhaps, but for a time, especially while the IoE evolves, that won’t be the case. Count on the early IoE bei... » read more
