Japanese Satellite to Provide Hyper-speed Wireless Internet Service

Posted February 23rd, 2008 by Steve Levenstein

KIZUNA hyper-internet satellite
Japan's KIZUNA satellite, successfully launched from the Tanegashima Island Space Centre on a domestically developed, Mitsubishi H-2A rocket will introduce a new era of hyper-speed data communications across Asia. How fast is hyper-speed? Try 1.2 Gbps... the "G" stands for Giga (billion).

Let's put things in perspective here: 1.2 Gbps is 150 times faster than the average high-speed ADSL connection rate (around 8 Mbps). It's also 12 times faster than FTTP, or fibre-optic communication delivery. What this means is that students, researchers or company employees in different Asian cities will be able to communicate with each other without experiencing any time lag. Now THAT, is awesome... and so is the launch of KIZUNA, viewable here but previously watched live by millions in Japan over the Internet. Naturally.

According to JAXA, Japan's Space Agency, the type of societal breakthrough enabled by KIZUNA isn't the main reason why the experimental satellite was designed and launched - though it's still a darned good one. We're talking super-high speed wireless Internet communication in a country that experiences dozens of moderate to major earthquakes each year, every year.

The bigger quakes cause widespread destruction to roads, gas & water mains, and - wait for it - wired communication services. With KIZUNA orbiting above, uninterrupted communication can be maintained when a ground-based network is disrupted by an earthquake or any other natural disaster. Not only in Japan, mind you, but in almost any Asian country - the service will be available at 19 different locations across Southeast Asia.

KIZUNA (which means "winds" in Japanese) was developed at a cost of $342 million and is expected to function for 5 years once it begins service this coming July.While it's up there, the satellite will be the test-bed for about 100 experiments. One of the most anticipated will be a test broadcast of the next generation of high-definition television.

Even disregarding its usefulness in the event of a disaster, the existence of low cost, super-high speed wireless Internet service throughout the length and breadth of Japan may inaugurate a new era of techno-culture in what is arguably the world's most technologically advanced nation. (via JAXA)

No Lag Time - Not Really.

"What this means is that students, researchers or company employees in different Asian cities will be able to communicate with each other without experiencing any time lag."

WRONG!!!!

As a matter of fact, the minimum lag time is twice the length of time for light to travel from one earth terminal to the satellite and back to the other earth terminal. Assuming the satellite is geosynchronous (like most communications satellites are), the time lag is at least 0.477 seconds. Yes, almost half a second!!

Not much of a problem for sending data files (assuming the communications protocol is reasonably well designed).

By the way, I believe in the world of spy satellites, communication of data at gigabit rates has been common place for several decades.

time lag

Submitted on February 24th, 2008 by Steve Levenstein

OK, any appreciable time lag. I don't have stats handy pertaining to land lines, but the lag in that case has got to be MUCH more than half a second. As for spy satellite technology, most of us don't have access to it. C'mon people, consider the possibilities here - and don't think that this breakthrough will be restricted to Japan and Asia. They just made it first (which seems to annoy some folks)... "Stop hyping it"? Ok... better, let's all bury our heads in the sand.

Kizuna doesn't mean "winds". "WINDS" = Wideband InterNetworking engineering test and Demonstration Satellite. The nickname of the satellite - Kizuna - means "bond" in Japanese.

I love seeing internet speeds increase and in this particular case, increase greatly. I generally get high speed internet via satellite and while those speeds have definitely improved dramatically over the last few years, these Giga speeds certainly up the ante….just a bit!

The super high speed ominous internet connection marks a turning point in Human evolution, the "on" era, when people are connected to a world consciousness and transformed into super humans.
