Li-Fi gets office install in Philips lighting

Broadband data-over-light, sent through lighting fixtures commonly seen in commercial buildings, moves a step closer to possible mass adoption through an apparently functioning smart-office installation in Paris.Li-Fi uses light waves for data communications, as opposed to Wi-Fi, which uses microwave radio. Li-Fi has 10,000 times Wi-Fi radio’s RF spectrum, experts say. The pilot installation by Philips is at a French real-estate company’s office.Philips Lighting, the giant lighting-system maker, says it is now offering Li-Fi modems installed within its existing LED luminaires, such as its downlighters. A luminaire is the building-industry term for a complete lighting fixture.To read this article in full, please click here

Fake News Spreads Fast, but Don’t Blame the Bots

Fake news spreads much faster than real news, and real people – not bots – are to blame, according to a recent study.

Fake news – defined by the researchers as stories debunked by six major fact-checking services – can spread 10 times faster than legitimate news stories, according to the study by researchers at the Massachusetts Institute of Technology.

The researchers studied rumors spread on Twitter between the service’s launch in 2006 and 2017. While some U.S. lawmakers and other critics have blamed automated bots for the spread of fake news before the 2016 election, the MIT researchers filtered out tweets spread by bots for their study.

The researchers found that false news not only spread faster than true stories, but it also had a much wider reach, according to the study, published this month in Science. The top 1 percent of news “cascades” – the researchers’ word for widely spread tweets – reached between 1,000 and 100,000 people, while Continue reading

IDG Contributor Network: The 4 decision makers at each company who drive how IoT is used

Internet of Things (IoT) is becoming important to remain competitive for almost every industry out there. Business goals for implementing IoT can range from improving internal operations to offering completely new services to improving regulatory compliance. But who at each company should be responsible for digging into this new world and defining how to implement IoT? We’ve learned that it’s important to have supporters across several groups to develop a truly successful IoT solution:1. Initiative lead Those who lead initiatives should always keep a pulse on competition, market conditions, changes in business models, risk assessment and supporting technologies among many other trends. This high-level perspective means executives should be the internal champions of initiatives like adopting IoT into an organization. Their involvement, however can range from setting high level direction and enabling teams within the organization to executing on an initiative directly.To read this article in full, please click here

What is the open packet optical switch, Voyager?

Modern web-scale data centers are thirsty for bandwidth. Popular applications such as video and virtual reality are increasing in demand, causing data centers to require higher and higher bandwidths — both within data centers and between data centers. In this blog post, we will briefly discuss the current challenges in the optics space as well as some of the key technical aspects of the Voyager’s DWDM transponder. In part two of this series, we will cover why Voyager is a unique, powerful and robust solution.

The challenges to accommodate longer distances

Within a data center, organizations are adding higher and higher bandwidth ports and connections to accommodate the need for more bandwidth. However, connections that accommodate longer distances between data centers may be limited and expensive. Therefore, a critical requirement for businesses with this challenge is how to support longer distance spans at higher bandwidths over a small amount of fiber pairs.

The optical industry solves the bandwidth problem using Dense Wave Division Multiplexing (DWDM). DWDM allows many separate connections on one fiber pair by sending them over different wavelengths. Although the wavelengths are sent on the same physical fiber, they act as “ships in the night” and don’t interact Continue reading
