prior to the transmission link was well known.
However, we find nothing in Lemson, and the examiner has not
convincingly pointed to anything in Lemson that would suggest
employing a signal level comparator for generating a single gain
control signal and a gain controller for adjusting the gain based
on the single gain control signal, both in each one of a
plurality of remote antenna units, as claimed.
While column 40, lines 22-29, of Lemson suggests the use of
a single gain control signal prior to the transmission link in
the prior art to Lemson, Lemson is comparing that to his
invention. There is no indication therein that the prior art,
being described by Lemson, also had the signal level comparator
and a gain controller for adjusting the gain based on the single
gain control signal both in each one of a plurality of remote
antenna units, as claimed.
While Figure 2 of Lemson, with its attendant description,
clearly does show a signal level comparator for comparing a
received signal level with a predetermined reference level and it
does show a gain controller (attenuators 32 and 34), the
comparator within the controller 42 generates more than a single
gain control signal (one signal each to the attenuators) and
there is no indication of an embodiment wherein only a single
