Engineers set new world record internet speed

Published

on

The world’s fastest data transmission rate has been achieved by a team of University College London engineers who achieved internet transmission speed a fifth faster than the previous record.

Working with two companies, Xtera and KDDI Research, the research team led by Dr. Lidia Galdino (UCL Electronic & Electrical Engineering), achieved a data transmission rate of 178 terabits a second (178,000,000 megabits a second) – a speed at which it would be possible to download the entire Netflix library in less than a second.

The record, which is double the capacity of any system currently deployed in the world, was achieved by transmitting data through a much wider range of colors of light, or wavelengths, than is typically used in optical fiber. (Current infrastructure uses a limited spectrum bandwidth of 4.5THz, with 9THz commercial bandwidth systems entering the market, whereas the researchers used a bandwidth of 16.8THz.)

To do this, researchers combined different amplifier technologies needed to boost the signal power over this wider bandwidth and maximized speed by developing new Geometric Shaping (GS) constellations (patterns of signal combinations that make best use of the phase, brightness and polarization properties of the light), manipulating the properties of each individual wavelength. The achievement is described in a new paper in IEEE Photonics Technology Letters.

The benefit of the technique is that it can be deployed on already existing infrastructure cost-effectively, by upgrading the amplifiers that are located on optical fiber routes at 40-100km intervals. (Upgrading an amplifier would cost £16,000, while installing new optical fibers can, in urban areas, cost up to £450,000 a kilometer.)

The new record, demonstrated in a UCL lab, is a fifth faster than the previous world record held by a team in Japan.

At this speed, it would take less than an hour to download the data that made up the world’s first image of a black hole (which, because of its size, had to be stored on half a ton of hard drives and transported by plane). The speed is close to the theoretical limit of data transmission set out by American mathematician Claude Shannon in 1949.

Lead author Dr. Galdino, a Lecturer at UCL and a Royal Academy of Engineering Research Fellow, said: “While current state-of-the-art cloud data-center interconnections are capable of transporting up to 35 terabits a second, we are working with new technologies that utilize more efficiently the existing infrastructure, making better use of optical fiber bandwidth and enabling a world record transmission rate of 178 terabits a second.”

Since the start of the COVID-19 crisis, demand for broadband communication services has soared, with some operators experiencing as much as a 60% increase in internet traffic compared to before the crisis. In this unprecedented situation, the resilience and capability of broadband networks has become even more critical.

Dr. Galdino added: “But independent of the COVID-19 crisis, internet traffic has increased exponentially over the last 10 years, and this whole growth in data demand is related to the cost per bit going down. The development of new technologies is crucial to maintaining this trend towards lower costs while meeting future data rate demands that will continue to increase, with as yet unthought-of applications that will transform people’s lives.”

GOOGLE OFFICIALLY ANNOUNCES ANDROID 11 FOR ANDROID TV

Published

on

By

A few weeks ago, Google officially released its latest system, Android 11 for smartphones. Today, the company announced that Android 11 will now be available for Android TVs. However, the Android 11 for TV is not a direct copy of Android 11 for smartphones. There are some features that are exclusive to the large screen. According to Google, it will partner with multiple OEMs and Android 11 on TV will be available in a few months. However, those who already have the ADT-3 Developer Kit can get the update today.

This system for Android TVs will retain most of the basic features of the Android 11 for smartphones. This system will come with better memory management and one-time permissions for secure workability. Google also did more work on privacy features to reduce the system’s vulnerability.

In addition, the Android 11 for Android TVs will come with an “Auto Low Latency Mode and low latency media decoding”. This system will also bring a new Tuner Framework with updated Media CAS support. Furthermore, this system will support gamepads, a feature that will be important for Stadia on the TV. Developers of Android TV apps can seamlessly test their apps with Google’s “test harness mode for Android TV”.

According to Google, the Android 11 system allows better control over TV functions. The company said the “…new framework functionality for managing System LEDs and physical microphone mute buttons also facilitate integrations for far-field microphone enabled devices”.

Google Chrome prepares new tab groups feature that creates groups automatically

Published

on

By

Months after announcing it, Google finally rolled out tab groups widely in the past couple of weeks. Now, an improvement could be coming to Chrome’s tab group feature — the ability to recreate them automatically.

In the latest Chrome Canary release, a new flag is present that describes a feature Google is working on. That flag, titled “tab groups auto create,” is one that has had us scratching our heads since it popped onto our radar earlier this week.

Google’s description, too, unfortunately doesn’t help matters. the company simply explains that the feature “automatically creates groups for users, if tab groups are enabled” in Chrome. What does that mean? We’re not entirely sure, but there are a few possibilities!

For one, Google might be able to remember tab groups from a previous session and drop them into a group when opened. Alternatively, Google could intelligently create groups based on similar types of tabs. At this point, it’s all up in the air. We can say pretty confidently, however, that this feature is not live in the latest Canary release.

Facebook Is Apparently Adding Instagram Stories to Its Key Application

Published

By

Facebook has built it no key that it would like to entwine Instagram into its principal blue app as a great deal as possible (to some Instagram users’ chagrin.) Its most recent experiment evidently requires placing Instagram stories right on Facebook.

In accordance to a report in the Verge, some Facebook customers have lately started looking at Instagram stories in their Fb story feeds. A Fb representative apparently verified the news to Matt Navarra, a social media marketplace commentator and advisor, and stated that it was a restricted examination. The representative added that Facebook would be listening to feedback from its group on the prospective new characteristic.

In a screenshot posted by a Twitter consumer and Navarra on Friday, Fb seemingly points out that not just anyone can view an Instagram story on Facebook. In get to do so, consumers have to website link their Instagram accounts to Facebook and have this viewing placing turned on. Fb states that men and women who don’t abide by a user on Instagram will not be ready to see that user’s tales.

Fb also purportedly pressured that even however tales will be in two sites, users’ overall practical experience would not improve. That is mainly because people will nevertheless essentially be sharing their tales with the similar persons on Facebook and Instagram. In addition, Instagram stories on Facebook (which will have a pink and orange circle) will surface with a user’s Instagram take care of. And even though the tales will be seen on Fb, end users will see all tale sights and replies on Instagram.

In new many years, Facebook has labored to convey all of its popular apps, which involve WhatsApp and Instagram, nearer with each other. Very last thirty day period, Facebook released a new exam working experience on Instagram messaging for some users. The new experience up-to-date the look of Instagram immediate messages and promoted the likelihood of chatting with individuals who use Fb.

Who knows, possibly in the foreseeable future we won’t have an application named Instagram or Fb. We’ll just have a person giant purple and blue app, owned by Facebook, that does almost everything.
