RE: high speed data

Hi Galt,

to realize 1Mb/s you will need at least 1Mhz or more bandwidth. This could be a problem on lower frequencies. Maybe 23cm/13cm is ok, but to use it in a city? I got no experience about this high frequencies. On the other hand is 1Mb/s not really much for streaming or copying large files - especially for many users. I don't know a solution for your problem, not even a commercial one.

802.11 MAY be a solution though the hidden transmitter problem still
bothers me.  Directional antennas increase distance but limit all
stations being heard.  point to point works for links but I'm looking
at the case of many users in a metro area sharing a common resource,
probably in a partial mesh star topology (many users linked via one
node who can't hear each other.  Full duplex would be usefull as well
and I could forsee many of the end users of this network regularly
moving large files between nodes (iso images for example or
installing/mirroring the latest suse) and realtime digital AV
streaming would probably be an often used app.
