Powell, OH | how is this going to work With the unavoidable 2+ second delay caused by satellite? Low latency is more important to VoIP quality than pure throughtput, which is the exact opposite of what DirecWay offers. | |

| Re: how is this going to work I read that too but it doesn't say if they will be high orbit (like now) or low orbit satellites. If they're high orbit single hop may help a little but most of the latency is still unvoidable and caused by the sheer distance the signal has to travel. | |

| "SPACEWAY employs high- performance, on-board digital processing, packet switching and spot-beam technology to offer single-hop connectivity,"
It's still going to suck. That's why the sat-phone companies (e.g. Iridium) use LOW EARTH ORBIT, not geosync. Of course, the sat-phone companies went bankrupt in a big way because the market is tiny and getting smaller every day. | |

| Delay is not that bad... The average delay on satellite for a round trip ping is 700 to 1200 ms ROUND TRIP (at least on Starband), typical is about 800 ms. Each way is about 400 ms typical. That can be worked around for large economic savings. The only problem in the delay for voice is when someone stops and is waiting for the other party to respond, the satellite delay will only ad about a second to this delay. | |

| Back in the 80's, as long distance competition was just getting started, there were satellite circuits competing with existing landline and terrestrial microwave.
The rule of thumb used to be that satellite circuits could be sold to Texans, but never to New Yorkers, solely due to the difference in their speed of speech....

| Voip is not 911 capatible Voip is not 911 compatible...that is why vontage is having a bad tinme with it...they might be now but they werent two months ago. Voip will take along time for it to catch on. you lose your satelite you lose your phone...you lose your cabel/dsl connection you lose your phone// twisted pair and powered cable telephony will be around for awhile | |

Competition!
Still not going to go to DirecWay, but it's still good news.
