Hi, I don't have a stake in either of these technologies but Windows magazine (2/99) has an article on High Speed Surfing that essentially states ADSL is faster than cable. They described SDSL and VDSL as even faster than ADSL but unable to handle poor line quality the way ADSL can.

I have no idea whether that is correct. It doesn't really matter. If the lay press spews it out as fact, the masses may well follow.

They seemed to be impressed but slightly less so by cable.

Jing, great post! I know the participates on the ATHM message board at The Motley Fool site would appreciate and benefit from your knowledge on cable, satellite, optical and broadband technology. I believe you would find some of their post enlightening too!

Hope to see your post there soon!

Best
Pike

You really missed the number 1 problem with satellite access. People complain about sharing bandwidth over cable, well think about satellite! You data goes to every subscriber on your channel. They have a limited number of channels to transmit on and a limited total bandwidth. Every single user shares the same bandwidth. This has extreme implications during peak usage.

Here's my list:

1) Limited bandwidth.
2) Still need a phone line and modem.
3) Fixed delay from request to response on every packet. (2.7 seconds? roughly 22k miles * 2/c)
I've got to imagine it becomes very annoying.
4) Cost.

Low orbit solved some of these problems, but you'll still have to deal with #1 and #4.
