HD radio won't just go away.

You make requests or upload files / data over the phone line. The download path to you is the satellite dish. If you are surfing the net your requests and upstream data are small and the downloads such as movie trailers, video, and streaming media are high bit rate. -- Telamon Ventura, California |

Typically the phone line or DSL or cable line flows both down & up across the same wire, but not satellite: DOWN - from the satellite UP - via the phone line So the down channel is broadband, while the up channel is narrowband. The thing Brenda forgot is that virtually all of these AM websites are optimized for phone line usage. I don't need broadband to DX to California or the UK or Australia via my 56K modem. Well, Wildblue and Hughesnet are the two major providers of satellite access in the US and they both use two way satellite connections. They do not use the phone. Both offer higher upload speeds than a conventional phone line can provide. Makes one wonder what else you don't understand. |

If you can now get up link and down link satellite then the up link bit rates can improve. Ping times will still be larger compared to DSL due to the propagation time to from the 22K miles away bird. -- Telamon Ventura, California |

(2) I looked-up two-way satellite communication on wikipedia before I posted, but it said the upstream is limited to only 2.4 kbit/s. That's a LOT slower than a 56k phone line connection. (3) If wikipedia is wrong, please provide a citation so I can update it. Back-up your "higher upload speeds" claim. |

Your posts show you don't have experience with what you are talking about. If you don't like that being pointed out, too bad.

(3) If wikipedia is wrong, please provide a citation so I can update it. Back-up your "higher upload speeds" claim. Go to the Wildblue or Hughesnet web sites. You'll find they offer 128kbit or higher upload rates. |
