The channel capacity is limited by
the frequency and time allocated to
it, and by the degradation (due
mainly to the thermal background
noise)
¡ The frequency reuse is in
neighbour cells not possible.
¡ In case of voice transmission, no
possibility to reallocate the unused
resource ( In a 2 persons
conversation only 40 % of the
resources are really used!)
¡ Terrestrial narrow-band systems
are very sensitive to multi-path
degradation, fading...
