1 edit | Shows what i know..me=dumb I thought satellites that were released in space never die unless something dies that couldn't be possibly fixed?
Unless something that dies that keeps it in orbit..

| Re: Shows what i know..me=dumb They don't "fall from orbit". When the onboard consumables get low, they let it drift North-South for a while, and then use the remaining fuel to boost it up and out to a graveyard orbit. About half the lift-off weight is fuel, and about 90% of that is used for North-South station-keeping. Once they're in the proper orbit, they drift very little East-West.

| Well...."kinda-sorta". Hughes (now Boeing) invented the "XIPS" Xenon-Ion-Propulsion-System which uses electric power to produce a plasma from Xenon liquid. It's very efficient, but still relies on having a tank of *something* to use. Eventually, you run out of "stuff" to use, which renders an otherwise "good" satellite defunct.

kudos:1 | Re: Must you call it broadband? Broadband in my book:
To be broadband, it must:
- Have data speeds comparable to DSL, Cable etc
- Have latency comparable to decent quality DSL, cable etc (on this, satellite fails)
- Have stability comparable to decent quality DSL, cable etc, which is in my experience with both around 95% uptime (on this, satellite fails: watch it die in fog, rain, snow, sleet, cloud cover, and when you accidentally bump the dish)
- Have stable speeds (on this, satellite fails except at 2am)
- Have priceing comparable to DSL, cable etc (on this, satellite fails: $700+ install anyone? Not to mention from what I've heard from alot of satellite users here, first install usally fails) | |

League City, TX | Well as much as I dislike the FCC I will use their definition
The term broadband commonly refers to high-speed Internet access. The FCC defines broadband service as data transmission speeds exceeding 200 kilobits per second (Kbps), or 200,000 bits per second, in at least one direction: downstream (from the Internet to the user’s computer) or upstream (from the user’s computer to the Internet).
This satellite will deliver plenty more then this so it is broadband internet. Dialup is 56 kilobits per second hence not referred to as broadband according to the FCC and is generally accepted to not be called broadband.

| Re: Must you call it broadband? The original definition of broadband was the use a medium (such as coax) with have multible separate channels, each operating at different frequency ranges.
This was in contrast with baseband where the medium had one channel encompassing a single frequency range and multiple users shared that one channel either in time division or stat mux.
your residential cable is considered boadband because it carried different channels of information on different frequency ranges. (your analogue TV channels, each on different frequencies, as well as internet service also in its own frequency range).
The term "broadband" for internet came from the fact that the first high speed internet service came from the cable companies whose media (the coax) is used in a broadband fashion.
"broadband" for internet was probably coined by mistake by clueless bimbos on news^H^H^H^Hentertainment channels like CNN etc and the term stuck.
Not all coax is broadband. 3270 terminals used baseband coax, as did ethernet when it was on coax (thin and thick wire).
mobile phones are hybrids. They have multiple channels, each occupying a different frequency range, but each channel also multiplexes different connections (GSM with time division, CDMA with collision detection/retransmission).
Boradband was genereally meant to say that the medium useed a wider spectrum of frequencies versus baseband that used a narrower range of frequencies. | |

| That's a Big Bird When Arianne lofts this one to orbit, it'll break records for the largest single unmanned payload from ground to GEO.
One fun problem they are going to have with this design is the hardening of the processors. I'm certain that it'll be a robust design with plenty of fault tolerance built in. | |

| Why Bother? I've had WildBlue in the past, that is until I discovered that EV-DO was in my area (and I live in the sticks). With EV-DO expanding so quickly what is the point of expanding Satellite at all? Besides, the latency is too high for it to be very useful to many people and the cost is way to high!

| | | You're in the sticks on the east coast--makes a big differen netwire,
You're fortunate because you live in "sticks" located on the super-densely populated east coast. Those of us in "sticks" farther west are just lucky to be able to get a cellular signal once and a while, let alone EV-DO. (There are still large areas near me where there is absolutely no cellular coverage.) EV-DO will never be built up out in the large, less-populated west. Outside large urban populations in the west, you'll only possibly see EV-DO along highways. | |
