ADSL may be suitable for
analog voice, but not digital voice, ie, MPEG2 based VoIP technology.
What is the bandwidth required for MPEG2 sound?
But Analog voice can only be heard
by a telephone set. Voice over IP can be heard, analyzed and understood by a machine. So in the
future you can call home to your refrigerator, with a DSP processor that decode the MPEG2, it
will understand your instruction to raise its temperature a bit. That's why Cable will win.
Maybe long term. But it will be a long time before people will be doing what you mention here. It requires the new technology to hook up to your refrigerator, hooked together into a local network at home. Plus it requires a substantial investment by individuals to be able to do it. Plus this is an extremely wacky example, since I can't figure why anyone would ever want to remotely control the refrigerator! Please come up with more compelling examples. Even if you replace "refrigerator" with "room temperature", I don't see that as a compelling application (i.e. one that will be widely adopted). For most applications, current analog voice is quite acceptable. When I call my parents, I do not need to hear them in THX or Dolby surround sound. |
