story category Satellite May Spread 1.2 Gbps Speeds Across Japan
Japan sprints forward in broadband and space races
(old news - 11:18AM Saturday Feb 23 2008)
tags: satellite · alternatives · world
Japan has just launched a satellite with the hope of using it to provide high speed Internet across the country. Japan’s goal is to make sure that the country has access to broadband speeds at all times, including when ground-based structures go down.
"If the technology proves successful, subscribers with small dishes will connect to the Internet at speeds many times faster than what is now available over residential cable or DSL services."
Those speeds are reported to be up to 1.2 Gbps. In addition to serving as a disaster network in the event that ground service goes down, the goals of this project include improving rural broadband and increasing opportunities for remote education and telemedicine throughout Japan.

1.2 GB/sec to selected businesses. Here is some info on sat capabilities:

»www.jaxa.jp/projects/sat/winds/index_e.html
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.
I could not find anywhere the full capacity of the satellite. It may be proprietary info they don't want released to the public.

Isn't this satellite? Are the pings going to be better, or is this just a huge pipe?

It's a lot more than that if you think about it. It's 22,300 miles up, another 22,300 down, then it gets routed to the website on ground, and then finally, it goes back up and down to you. It totals about 90,000 miles.

My point was, the distance will never be reduced, thus the pings will never be reduced.

Newer satellites have routing built in. They can actually beam it to a closer downlink and uplink center to try and lessen lag. I have heard they are dropping the latency by as much as 200 ms. Which is a nice drop for satellite.

Er, internet packets are a form of electromagnetism. EM waves travel at ~186,000 miles per second. This means even if it were 90,000 miles round trip, the packets could traverse the distance in about half a second.

The satellites are 22,000 miles above the equator, which means that if you look at the geometry, it will be further away than that from us folks in North America. Nonetheless, it still would take well less than a second for the round trip.

Well, I kind of guesstimated it from what I've learned about DirecTV as an installer.

Why, do you not agree?

Re: Satellite - 22,000 miles?

Satellites such as these are put into geosynchronous or geostationary orbits, a position where they are in the same apparent place in the sky all the time, or at the same place at the same time each day. That makes them easy to aim at with the ground antenna. Such orbits are always at 22,000 miles up. »en.wikipedia.org/wiki/Geosynchronous_orbit

Re: Satellite

No, i'm just surprised. I imagined they'd be closer. 22,000+ miles up is nearly three times Earth's diameter. Almost three Earths would fit between Earth's surface and the satellite. That's far!

In contrast, the International Space Station and Shuttle, when it goes to the ISS, orbit at less than 250 miles up. 189-246 miles vs 22,223 miles, a huge difference.

Satilite broadband could be useful

It could be used to deploy bulk traffic across the internet instead of choking up landlines for other things. Say you ordered a movie online the first 20 minutes are blasted across landlines and the rest of it is delivered via satilite at even faster speeds.

Re: Satilite broadband could be useful

for large file-size items(like movies) you don't care about lag. it takes 30 sec- 1min to buffer, then its streaming...

Lag only counts in on-line gaming, (to an extent) web brousing, and things of that nature. A video stream or large files or even VOIP/ IPTV this is great for

from the JAXA website...

"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."
It is satellite, but there is no mention of latency (lag)... but keep in mind, this is intended for fat-pipe usage and rural areas where there is nothing else available AND during disasters (like typhoons and earthquakes they get there frequently)

This is an awesome thing!

I hope OUR country looks seriously at this implementation. For regions with nothing better, this is awesome.

Huge speed with 3,000+ ping times is useless except for people who upload and download tons of things.

Re: So?

Which makes it perfect for disaster response where the biggest problem is access to massive asset inventory and GIS datasets while out in the field after the communications network is down.
Residential broadband should not even be allowed to see a service like this at all; it should be reserved for critical infrastructure uses.

 i beg the difference. if you download and upload that much this is a good and cheaper solution for the ISPs to provide you with cheaper access. plus if you are dl that much, you probably select the files/movies or what ever it is and walkaway until is done. so the ping times is relative unless you are one that monitor sec by sec a 5 or 30 gb download.

Re: So?

The article says that businesses will have access to 1.2 Gbps with a five meter dish. This would be a perfect way for localized ISP's to buy access and then send, say 20 Mbps, to rural customers via a wireless connection of some sort.

If I lived in the boonies, I would be glad to put up with the high latency if I could get 50-100 Mbps downloads. This would be much better than DirecTV's 1 Mbps with the same latency. Unless you play online games, there is no disadvantage except that websites will load a few milliseconds slower.

I used to be an installer for a DirecTV contractor. You and I both know full well that HughesNet (formerly DirecWAY) is nothing but the Internet arm of DirecTV. Why you attempt to argue and split hairs I have no idea.

This sounds awesome, but how many people can be on it before the pipe starts to sputter? but like someone mentioned earlier, i wouldn't doubt they would put caps on there and i wouldn't doubt they'd traffic shape or filter it.

that's one of the questions this experimental satellite is meant to answer.
WINDS (Wideband Inter-Networking engineering test and Demonstration Satellite ) is a testbed for several newer technologies.
»www2.nict.go.jp/w/w122/winds/eng···dex.html
while it will be tested in remote parts of japan, it will also cover many countries in the southeast asian hemishere, palces that don't have and are unlikely to get broadband coverage any other way any time soon.
It is mostly intended to serve gov't and business interests due to the high cost. ($490 million US for a 5 year lifespan)

High-speed Broadband over Satellite for the USA

The Japanese are serious consumers. The Empire of Japan does provide subsidy for its communications system.

But this is the good old USA where special interests determine communications policy. The game is rigged; it is not competitive. When our Manchurian Candidate headed the Senate communications committee, he paid off his honest and supportive lobbyists with legislation and policies designed to foster their employers.

Why is high-speed broadband widely available in Hong Kong, Taiwan, South Korea, and Japan? Because pro-consumer public policy responds to citizen demands. Anybody in the USA think that the communications moguls are going to be competitive, innovative, or even attuned to consumer interests? All they need and want is to maintain their monopolistic, non-competitive, favorable positions. They contribute to the politicians and the politicians protect their selfish interests and profitable positions. That is how a mature, devolving system works in post- modern America.

Sweet .!

Even if I cant get 1.2 gbps , just 100 mbps for me would suit me just fine.

To the Japanese, You would sell millions if this Satellite (or more) were GLOBAL...

Either way , at least someone out there is trying to get broadband to more people instead of complaining about it.

Many things have been done with Satellite

Low Earth Orbit (LEO) only have a 200 mile to 950 mile trip at the speed of light lower ping times as with the new Hughes (aka the owners of DirecTV) system they are testing now with large down and upload speeds. I have used Satellite for many types of service and it works. The government as used it for many years and major phone companies used it for most international calls for years. Ever seen the ping times on an EV-DO system 200-1800 ms and the round trip on that system is only 1 to 4.5 miles.

Re: Many things have been done with Satellite

EV-DO has ping problems because each packet uploaded must be given a time slot by the NOC's computers (which control many cell towers and control the hand offs between them) before it can be sent. So you need a couple round trips just to send the first packet in TCP 3 way handshake.

The ping for the satellite that Level3 backbone is using is only 74 ms for pinging bbc.co.uk This a low ping and it's good for online playing I could even send you a screenshot if you don't believe it I'm in Canada. I believe that this satellite will be able to have pings lower than this
