Where 5G Works, And Where It Doesn’t
By Ed Sperling - 16 Jul, 2019 - Comments: 0

The rollout of 5G hype has begun. Companies are building 5G chipsets for mobile devices, and they are working on the infrastructure that will allow massive amounts of data to move freely between devices. There is little doubt that more bandwidth is required everywhere. Files are growing in size, particularly with streaming video and images and various flavors of AI and machine learning.

The Power Of Integrating Bluetooth Low Energy Into SoCs
By Synopsys - 15 Jul, 2019 - Comments: 0

The Bluetooth Low Energy (BLE) specification, released in 2011, enables designers of System-on-Chips (SoCs) to maximize the battery life of IoT devices and minimize the implementation costs of wireless sensors and other “connected things” by maximizing sleep time and simplifying Radio operation. Because it is built on the established ecosystem of Bluetooth Classic for mobile phones and P... » read more

5G OTA Test Not Ready For Production
By Kevin Fogarty - 09 Jul, 2019 - Comments: 0

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

Miles Wide And High Security
By Ed Sperling - 07 Feb, 2019 - Comments: 0

Talk about security in autonomous vehicles seems to have subsided. It shouldn't, because the problem is far from solved. In fact, it's not just one problem. It's layers upon layers of problems spread out across all roadways, technology design houses, IP developers, network infrastructure, and the entire supply chain. And even though one vehicle's security may be bulletproof, it may be no... » read more

How Much Data Can Be Pushed Through Copper Wires?
By Jeff McGuire - 08 Oct, 2018 - Comments: 0

As the amount of digital data grows, so do requirements on the speed of the transmission at all levels of the transmission chain—between dies in a shared package, between packaged chips inside a device, and between devices. The communication channels encountered at every stage of this communication are different in nature. Those between dies in a shared package, or between packaged chips in a... » read more

Chord Signaling by Generalizing Differential Signals
By Kandou Bus - 06 Aug, 2018 - Comments: 0

Chord signaling is a multi-wire signaling approach that is a generalization of differential signaling. With differential signaling, a single bit is transmitted on two correlated wires. In Chord signaling, n bits are transmitted on n+1 correlated wires. The number of wires, the Chordal code and the design of the multi-input comparators together. Background Companies connect chips in elect... » read more

The Route To 5G
By Arm - 09 Nov, 2016 - Comments: 0

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
By Ernest Worthman - 07 Apr, 2016 - Comments: 0

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
By Ed Sperling - 01 Feb, 2016 - Comments: 1

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
By Ernest Worthman - 03 Dec, 2015 - Comments: 0

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
