The Route To 5G


The mobile phone has seen explosive growth over the last two decades to become an essential part of our everyday lives. Right from the outset, ARM has been at the heart of these devices enabling ever more sophisticated capabilities whilst maintaining a focus on maximizing battery life through industry leading power efficiency. The complexity of smartphones is not often fully appreciated, with ... » read more

Mobile Edge Computing For The IoE


More attention is being focused on the edges of networks as the IoE begins taking hold. The reason is that the current wireless infrastructure is inadequate for handling the billions of endpoints that will make up the IoE. So for the IoE to realize its full potential, it will either require some sort of add-on infrastructure or a new discovery in physics. Edge networks were not always suc... » read more

GridComm: Smarter Grids


Streetlights were considered a big improvement over gas lamps when they were first introduced in the late 19th century. And since then, not much has changed, other than the addition of more streetlights as cities and towns grew and different kinds of bulbs. But streetlights do account for about 40% of a city's electricity budget, which can amount to tens of millions of dollars a month for la... » read more

Super Wi-Fi For The IoE


From time to time the term “white space” may have popped up in wireless spectrum discussions. Generally, white space describes parts of the licensed radio spectrum that are unassigned, unused, only used part time by the licensees, or not used by them in certain geographic locations. Virtually every country in the world has some of this. Most of this exists in the television spectrum, and is... » 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

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

BLE For The IoT


Bluetooth low-energy (BLE) is one of the emerging disruptive technologies for the IoT. Also referred to as Bluetooth low-power and Bluetooth smart, as the Bluetooth SIG is calling it, this technology will enable the next level of IoT vertical devices, such as medical devices, home automation, retail, wearables, and much more. For consumers, it comes down to the Internet of Your Things (Io... » read more

Smart Grid Security


Smart energy is an all-inclusive term that refers to upgrading the energy grid so it can support bi-directional flow of energy and data. Such an endeavor involves adding connectivity, communication, and security features not only to the smart grid but to the many devices connected to a smart grid. But how do you ensure all devices on the network are secure? This paper looks into two key softwar... » read more

Blog Review: April 2


Mentor’s Nazita Saye compares roadway roundabouts to networked systems. One roundabout works fine, but add in a bunch of them and you have a massive traffic jam. How many roundabouts are in your design? Cadence’s Richard Goering interviews Stan Kroliskoski, chair of the IEEE Design Automation Standards Committee, about four working groups on EDA standards and what’s ahead. Speaking ... » read more

SoC Integration Mistakes


Semiconductor Engineering sat down to discuss integration challenges with Ruggero Castagnetti, distinguished engineer at LSI; Rob Aitken, an ARM fellow; Robert Lefferts, director of engineering in Synopsys’ Solutions Group; Bernard Murphy, chief technology officer at Atrenta; and Luigi Capodieci, R&D fellow at GlobalFoundries. What follows are excerpts of that roundtable discussion. SE... » read more
