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. |

| I was wondering the same thing. There is not a way that voice traffic could make it on time. It is the same reason why the old over-seas calls where so horrible, because they used satellites. With fiber running to most countries now it is no longer as bad.
DirecWay service has an enormous amount of latency. I guess another thing is a jitter problem where the time for travel of the packet changes often.
Then there is the clouds problem. When a bad storm rolls in there goes your phone. Reliability is something we have all come to expect with our phones, more than our internet connections.

Spaceway is a whole different animal than DirecWay. Operating in globally assigned Ka-band spectrum, SPACEWAY employs high- performance, on-board digital processing, packet switching and spot-beam technology to offer single-hop connectivity, regardless of location.
There is no NOC or terrestrial routing involved. Oh, this is business-class service we're talking about. The DW6040 is going to be really expensive. Since you'll need a DW4020 too, your looking at around $2000* just for hardware. 
* Estimated price.

| 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. |

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. |
