Initial tests for Kizuma satellite successful
(old news - 06:39PM Wednesday Apr 09 2008)
tags: satellite · business · bandwidth · world · HughesNet Satellite Broadband
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 when terrestrial solutions go on the fritz during disasters. 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):
KIZUNA satellite communication system aims for a maximum speed of 155Mbps (receiving) / 6Mbps (transmitting) for households with 45-centimetre aperture antennas (the same size as existing Communications Satellite antennas), and ultra-high speed 1.2 Gbps communication for offices with five-meter antennas.
Lets briefly compare that staggering capacity to leading U.S. satellite broadband provider HughesNet, who currently can't consistently provide customers even the bare minimum of what they're advertising because of capacity problems. While Japanese consumers' satellite latency won't be any better, hopefully their "FAP" will be.

HughesNet sux

wow why can't HughesNet afford one or two of those satellites

this totally sux we(USA) are 3rd world

I'm glad to hear the test were A-Ok. I was starting to get a little worried

With speeds like that........

FAP would be soooooo cruel. You would reach it in less than 30 minutes....lol. Still, this just goes to show how a lot of people are getting the short end of the stick when it comes to this type of service in America.

We will see if it will work any better than Wildblue or Hughesnet......

This makes comcast seem like dial up! :(

I hope someday soon we will see speeds like that in the USA!

Only on speeds. On ping time (which you need for doing anything fun), it makes dialup look glorious.

But if you're someone living in the middle of nowhere and isn't a gamer, the pings wouldn't make a difference as long as you get the speed!

Wow...

That's really impressive, especially for satellite... though, 155/6 has to be among the least symmetric plans out there.

Though, I notice this is JAXA, a Japanese government agency, behind the proposal... cue the "free market" people, I guess.

Re: Wow...

155mbps is great......but really when your talking 1200 - 1400ms of latency does it really matter?

I'd rather have better latency then speed..........without good latency you really have nothing.

Re: Wow...

Actually I'd like to see this as a way to deliver large content where latency is not an issue. If we could work out QOS methods where downloads and such were put on high latency paths then more interactive content could be handled on the low latency paths.

Well it depends on what you're doing- if you're just viewing webpages and downloading files latency isn't a huge issue, but when you get into real-time things it does become one... hm, isn't online gaming very popular in Japan? That would probably injure this product.

Maybe there is Japanese Self-Defense Force interest in this satellite? Having broadband available even after a major earthquake could be useful to more than just the general public.

Holy cow! Wow is right. In one hand I'm wishing we had something like this in the USA and... well, you know in the other. I wonder which will fill up first.

Something like this could make living in the sticks a whole new ballgame.
If we did get something like this and it worked, especially if they could improve the latency issues, maybe there would be mass switching of service practically overnight. Then again maybe not because you'd likely have to sell your soul and a kidney to afford it.

Pricing would be retarded

It wouldn't matter if we did have it here in the U.S.. Somehow a damn oil refinery will have a light bulb go out and it would sky rocket the prices of the satellite access.. Don't ask me how, but the lame ass excuse's company's come up with to restrict and bump up fees is nearly insane...No.. No it is insane!!

Go ahead, I suspect that you will find the trade offs to not be worth it, assuming you are not a big city ant hill resident already. Although, high speed and good food.....makes it almost worth it except I have been over there and I will take Qwest 1.5/1 service and my house over 100/? and the ant hills most people in my income bracket live in over there.

Yeah but

How many connections can run 155 Mb and 1.2 Gb before the bird is saturated and no one gets that any more? Only so much data will fit through a radio link that has limited licensed radio bandwidth ... it's not like it's tethered by fiber or something.

It can be if the satellite is tied to the earth through centripetal force.

Re: Yeah but

Ha, yeah, if only they had a cable strong enough.

But seriously, there are a LOT of people here who keep wishfully thinking they can get some wireless high bandwidth broadband solution to bypass their crappy, greedy or nonexistent last-mile oligopoly, but it's just not practical nor ever going to happen.

Radio is too bandwidth-limited to cover the number of people in a large area, and too expensive to try to serve a lot of small areas. Cell service succeeds because of the low bandwidth and high subscription cost of all the handsets funding a relatively large number of towers.

Clearwire is about as good as wireless broadband of any kind is ever going to get. Anything else is same stuff, different channel.

Re: Yeah but

Should have included a line about the space elevator in my OP. But then its not flame bait.

Your right. Radio gets expensive when you have to split "cells", just as with cable tv nodes. There is some hope in wireless through using unconventional bands, MIMO and its friends, and higher transmit powers.

Ah, one of the wishful thinkers.

Yes, but the difference is, a cable node (or DSL RT) can have fiber run to it, be wired in many branches from there to homes as needed, and thus a single node can carry MAGNITUDES more data than any radio transceiver, which has to operate in limited licensed bands competing with all other radio services, and the only way to use the same frequency for more than one subscriber from the same radio location is to try to make it directional or polarized. Tricks like these and MIMO transmission etc only give a relatively small boost in capacity and don't help the fundamental problems much.

Wireless broadband must ALWAYS be expensive, slow or FAP limited, much more so than cable or DSL, because of the above. This is a physical limitation of the topology and can't be wished (or even geniused) away.

Oversubscribing much?

I haven't seen any mention of the total capacity of this satellite. It's not so impressive if each of those 155Mbps to 1.2Gbps links are all sharing the same 1.2Gbps maximum capacity.

Not too bad ping.

The ping on this would only be 600-700ms possibly 500ms. The reason most satellite internet providers are around 1200ms is because THEY INTENTIONALLY CAUSE THIS BY TRAFFIC SHIFTING...even worst than Comcast.

Have you found a way to transmit data faster than the speed of light?

Re: Not too bad ping.

WOW, did you even read my post? the ping for satilite is around 500-700ms-thats going at the speed of light. Wildblue uses traffic shifting, because this traffic shifting involves examining and prioritizing each protocol. THIS ADDS 400ms to 700ms of LAG ON THE SYSTEM.

Please read before you post nonsense.

Latency will be the same. Now the biggest advancement I see here is that radios on both ends can communicate at such rates over satellite. Now since this seems to be able to have multiple uplinks and downlinks, I suppose there are multiple channels in place a few khz apart in order to achieve those speeds.

Capacity depends on what type of hardware placed on the satellite by NICT »www.nict.go.jp/index.html

It might be 155 Mbps now, but wait a while

The satellite is new, with few users. Let's see what the bitrate is when 10,000 or so people are online watching streaming video, downloading pirated movies, etc. It sure as hell won't be 155 Mbps.

Driving on the Interstate at 3:00 AM is pleasant, but during rush hour ...
