Dear Jim:

Shant is not always absolutely correct:

a) The higher the frequency, the more LOS
the propagation becomes. So MMDS is not LOS,
but LMDS is (though the LOS can be created
artificially through the use of reflectors).
A building wall is not a good reflector,
since it creates a loss, which when combined
with additional rain induced losses, deteriorates
the quality of the link.

b) The higher the frequency, the more rain has
an effect, although at LMDS frequencies, rain
only creates the need for either power or
rate control.

c) The higher the frequency, the smaller the size
of cells. This is the key advantage of LMDS:
frequencies can be reused in neighboring cells.

And, yes, the available bandwidth at high frequencies
is very large, which made LMDS possible.

Best regards,

Bernard Levy
