Before I can support any sort of a radio based LAN, I'd like to take a
good close look at how this proposed system is supposed to work. Just
off the top of my head, I can come up with a number of MAJOR problems
that would need to be adressed. These include things like data security,
multiple installation interference, and interference with non-LAN radio
systems, or even non radio electronics!
Anyone within range of your office would at least be able to listen in
on your network traffic, and could even connect to the network without
your permission! The thing is, fifty metres is a long reach in a typical
office building. This would include not only the entire floor the network
is installed on, but at least five floors above and below the network too.
In a typical large office building, several companies would have offices
in the same building. Given that the radio signal from the LAN would
extend many floors above and below the network, how do you prevent
interference between two networks (belonging to different companies)
that happen to be located on different floors?
