The entire internet is stored and delivered using 540 billion trillion electrons.

The world’s first all-electric propulsion satellite is now operational

Posted by in categories: electronics, internet, space

Boeing has announced that the ABS–3A, the world’s first all-electric propulsion satellite, has commenced its tour of duty.

The communications satellite is being operated by ABS, a Bermuda-based satellite network that provides TV, Internet, and cellular services across the world. Unlike conventional satellites, which have mostly used propellant systems that burn chemicals of one kind or another to get about the place, the ABS–3A makes use of a xenon-ion propulsion system to achieve thrust.

Specifically, the all-electric propulsion system uses electron bombardment to create xenon ions, which are then expelled by the spacecraft, producing thrust in the opposite direction.

Swarms of smart nano-satellites may offer global connectivity (With video)

Posted by in category: internet

One day we may have global connectivity — even in the remotest parts of the world — thanks to teams of tiny, intelligent, swarming satellites called CubeSats.

In an industry that doesn’t like change and definitely doesn’t like to rely on the latest and greatest in technology, CubeSats appear to be changing the game for the space industry.

And one of the things these cube-shaped satellites could be changing in the next 10 years is how to help people in impoverished or remote parts of the world get long-sought Internet access.

How 5G will Power the Future Internet of Things

Posted by in categories: internet, mobile phones, transportation

At Intel Developer Forum in San Francisco August 18th – 20th, two Intel executives discuss how 5G network capabilities will transform the way we live.

Imagine taking a trip to a cabin in the woods to get some work done and have a mini-vacation. Today, given our need for wireless connection, that’s a sketchy proposition.

You’ve got GPS in your rental car, plus your laptop, your smartphone, maybe a tablet or a smartwatch. But what if there’s no cable? What if there’s no Wi-Fi connection? What if the cellular connection is weak?

What is a Blockchain?

Posted by in categories: bitcoin, cryptocurrencies, economics, finance, government, internet, transparency

This short post is not about Bitcoin. It’s about a new method of organizing and arbitrating communications that is at the heart of Bitcoin

We hear a lot about the blockchain. We also hear a lot of misconceptions about its purpose and benefits. Some have said that it represents a threat to banks or to governments. Nonsense! It is time to form a simple, non-political, and non-economic explanation…

What is a Blockchain?

The blockchain is a distributed approach to bookkeeping. It offers an empowering, efficient and trusted way for disparate parties to reach consensus. It is “empowering”, because conclusions built on a blockchain can be constructed in a way that is inherently fair, transparent, and resistant to manipulation.

New York is getting wired with traffic signals that can talk to cars

Posted by in categories: internet, transportation

Behind self-driving, vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication is one of the biggest sea changes in transportation technology on the horizon — it could have an enormous impact on driving safety, if it’s implemented quickly and correctly. The concept is pretty simple: cars, signs, and traffic signals all communicate to one another over Wi-Fi-like airwaves, so that drivers (and automatic safety systems built into cars) have more information about the traffic and environment around them. (I got a compelling demo of V2V tech put on by Ford at CES a couple years ago, and I can say that the promise is pretty huge.)

There’s no federal rule in place for requiring V2V yet, but the US Department of Transportation is hoping to get those rules in place by the end of this year — and in the meantime, it’s rolling out huge new pilot programs to put the technology to the test. In the New York City boroughs of Manhattan and Brooklyn, traffic signals will be equipped with V2I hardware, while up to 10,000 city-owned vehicles will be outfitted with V2V. (It’s unclear whether drivers of these vehicles will have access to the data through instrumentation, or whether it’s just being collected as part of the DOT’s ongoing V2V research.)

Elon Musk has asked if he can launch 4000 wifi satellites into space

Posted by in categories: Elon Musk, internet, space

Elon Musk has officially requested permission from the Federal Communications Commission (FCC) to launch a 4000 strong flotilla of satellites into orbit.

Elon Musk’s space company ‘SpaceX’ announced their primary plans in January with the official request coming early last week. If all goes to plan the satellites could be in orbit and the Internet operational within five years.

While satellite internet is not new technology, SpaceX plans to reduce the enormous latency over a space connection by launching the satellites into a low Earth orbit at around 650km. The low orbit and slower speeds mean 4000 satellites are needed to cover the earth, far more than necessary for higher orbit networking.

Physicists develop key component for terahertz wireless

Posted by in categories: electronics, internet, mobile phones, physics

Terahertz radiation could one day provide the backbone for wireless systems that can deliver data up to one hundred times faster than today’s cellular or Wi-Fi networks. But there remain many technical challenges to be solved before terahertz wireless is ready for prime time.

Researchers from Brown University have taken a major step toward addressing one of those challenges. They’ve developed what they believe to be the first system for multiplexing terahertz waves. Multiplexers are devices that enable separate streams of data to travel through a single medium. It’s the technology that makes it possible for a single cable to carry multiple TV channels or for a fiber optic line to carry thousands of phone calls at the same time.
