The Big Kizuna

Tipped by GOLFnSUN See Profile
Last February, Japan launched their Ka-band WINDS (Wideband InterNetworking engineering test and Demonstration Satellite, aka Kizuna) satellite with the hope of using it to provide broadband country-wide at all times, particularly during disasters or Godzilla attack. The Japanese Aerospace Exploration Agency is currently conducting successful tests on the satellite, which by July should provide Japanese homes with speeds up to 155Mbps (businesses could see up to 1.2Gbps). Initial tests seem very promising:
Engineers testing a recently launched Japanese data communications satellite have succeeded in establishing a two-way Internet link running at 1.2G bps (bits per second) each way, they said Monday. The speed represents a record for satellite communications, according to the Japan Aerospace Exploration Agency and the National Institute of Information and Communications Technology.
Technically it was two 622Mbps channels, but Kizuna is still kicking the hell out of HughesNet's Spaceway-3 and taking its lunch money.

Fast with lag

When they solve the latency problem, then they'll have something

Re: Fast with lag

Just be careful you don't hit certain frequencies:

Warp factor 7 ?? to overcome normal speed of light?

But seriously, they did reduce overall latency by cutting in half the # of trips up and down to handle one internet transaction:
One of the satellite's special features is an on-board Asynchronous Transfer Mode (ATM) switch. In other satellite Internet systems data sent to the satellite has to be sent to an earth station, demodulated, switched to its destination and then remodulated and sent again via the satellite to reach its destination.

I'll put up with some latency for speeds like that- though I don't play online games much.

Being as resourceful as the Japanese tend to be, I'm sure they'll very soon come out with a way to make something go faster than the speed of light.

Max speeds for a std home antenna are more reasonable

uplink communications at 1.5M bps and downlink at 155M bps using a compact 45-centimeter antenna
And I suspect they will have tiers with speeds lower than that for most users.

Kizuna is still kicking the hell out of HughesNet's Spaceway


Hmm maybe you think Hughes knows this and sees a lot more money in Sat TV? Why Spaceway-2 was re-assigned TV duty?

To me the bottom line is there are so many natural restrictions to sat internet, it is only useful for mobile applications or as last resort for remote locations. It will never be mainstream in the near future and should not be promoted or advertised as such.

oooooohhhhh

Apple needs one of those 1.2Gbps Satellites for itunes & iphone

makes u wonder why don't netflix or blockbuster launch there own Sat's with those speeds u can deliver HD movies in few seconds.

+
saves $0.40 stamps
saves tree (paper)
no pollution (fuel USPS waste)
super fast delivery

wonder why directv can't do this they already got the satellites in space they just have to stop making movies playback in real time and deliver the whole payload in few seconds to the receivers instead of letting the DVR software capture the movie in however long is the movie length.
most likely there Sat's were not made to work that way

they are doing that part way they also use your internet link as well.

Re: oooooohhhhh

Yep. Mine (My new HD DVR) uses ethernet to download VOD and other apps I have not tried out yet. The device specifies that you have at least 768K to download.

So I think Directv is using ethernet (gets rid of that stupid phone line) with there extra sats to provide some services that will blow everyone else out of the water.

hmmm.....

me thinks the Japanese always have "thunked" outside the box. kudos and props to them. We should be doing this here, but will not happen in my lifetime.Peace

Could you even use the full 155Mbps. When trying to download files from the net.

Re: hmmm.....

Well, some fiber ISP's in US have offered cheap 100 megabit connections for a while now and people find a way to use that connection. Back in 1998 I've had no problems alone fully utilizing 45megabit DS3. A speedy connection simply allows you to do more things at the same time and finding use for additional bandwidth is always easy. As some say, if you build it they will come.

How big is it?

Knowing the Japanese penchant for miniaturization the satellite is probably about the size of a shoe box.

Presto the magic man is right again! Ain't i great?

Hey what do you expect? I've been right about everything my whole life. Like when i said the future of Canadian broadband is satellite. Right on cue presto ha, ha, ha! Here it is. Canada's salvation from these oligopolies who bilk Canadians dry. But no more, it had to happen and it's happening later rather than sooner because of these Canadian's naiveties.

"Being as resourceful as the Japanese tend to be, I'm sure they'll very soon come out with a way to make something go faster than the speed of light"

As cool as that would be, it is impossible to go faster than the speed of light.

Nice for them

I bet videotron will offer 150mbps soon but with a 60GB cap. lol

*yawn*

It sounds like 1.2Gbps shared between all the customers. That's enough for seven 155Mbps subs before they're oversubscribed.

Contention != oversubscription. All bandwidth apart from leased circuits is contended.
