| Finally It will be interesting to see what actual results/performance will be when companies like Wildblue finally begin service. Even if its Ka band, latency will be still be the problem for interactive applications with the approx .5 second additional delay. Remember with Satellite you can't beat the speed of light and no matter how bright the light is you can't shine it through a brick wall for example in a downpour of rain. |

wouldn't the high latency be like using an older pc on those applications anyway? I think most of those people who need it would be more interested in the speeds for moving big files I would guess.
Rather interesting though.

Yup. I got rid of Primestar back in the day because when a bad storm would wake us up in the middle of the night and we would turn on the Weather Channel to see what was happening; we wouldn't have a signal for all of the cloud cover. |

Broomall, PA | Well I still got Dish Network and it really takes a heavy downpour to make it go away. I got my Dish so well peaked using a spectrum analyzer from my work. |

Anybody happen to know why nobody has yet put a LEO broadband service satellite out there? These other services I presume are all geosynchronous satellites and are waaaay out there which is why the latency comes in. With LEO, it wouldn't be nearly as bad, so I'm wondering why no LEOs? Is it because you'd need several to cover the U.S. and canada since they're closer in?
I've read the Iridium project used LEOs to get around the latency which made phone communications somewhat annoying.

i never had primestar but i have had dish and directv and i have never had it go our for more than a minute or 2 even during bad snow storms. maybe you had a bad install or something. and if all it took was a downpour of rain to block the signal there would no be so many subscibers to dish and directv. |

Several is an undertatement. Deploying a LEO sat network is expensive. At this point it doesn't make economic sense. |

Re: More Ka-Band and Services Info Here is a quick update and a some answers to some of the questions out there.
Most of the technical questions can be answered by doing simple searches on the net for Ka-Band in general so I am not going to duplicate that info here.
Since this is new 'commercial' level Ka-Band high speed multimedia and internet services, there will be a period of breaking in the systems and getting the bugs out when it becomes available the end of 2004. This by far will be the most turn-key and easy to use mobile and fixed technology than what is currently out there like Direcway, DatStorms, and StarBands.
I have found information about the most asked question about the latency involved. Most of the other posters here are correct in that you cant get faster the the speed of light however the Ka-Band is pretty close. Which allows us to get around 200-milliseconds of latency round trip of about 3-4 hops. The popular belief is that because the new sat technology will give us massive amounts of bandwidth capability both on the download and upload, that does not help the fact you are still held back by the physics of the speed of light. It will seem like things are moving very fast however you will still have the minimum of 200ms of latency or so and not counting extra hops around the net.
With that being said, there is a great opportunity for us to get access to this technology in a short period of time. Right now we are offering the FIRST certifications and industry level training plus SBCA Level 3 certification in Nov 2004. If you are in the state of TX or are going to be in the area for this event, please contact us for more info or visit our site. »www.datasatplus.com
