[opendtv] Re: 5th gen receivers

25 to 35 years? It sounds surreal. And here I am thinking of a wireless 
mesh Gbps network that could be built now.

Just how does a broadcast system that is stuck in the stone age with 
8-VSB and MPEG2 and can't quite deliver a 1080i signal well survive for 
35 years in the radical world of change we live in?

Or for the next five years for that matter.

The technology to build a wireless 12.5 Gbps mesh network exist now and 
cost in quantity would be about the same as that for the initial ISDN 
modems that were sold in 1995 that delivered 144 Kbps. In ten years that 
will be the NORM in major cities IMO. For example in 1995 I was selling 
ISDN at 144 Kbps and talking to Time Warner about using their fiber to 
deliver 10 Mbps Internet. They thought I was crazy. Ten years later they 
are broadband.

BTW a 12.5 Gbps network is equivalent to 8375 T-1's or 100,500 ISDN lines.

Who will be watching OTA DTV in 35 years using 8-VSB and MPEG2?
