Appeal No. 1999-0084
Application No. 08/448,854
The operating transmission ranges of omnidirectional antennas
at each of the central stations 10, 26, 42 and 62 are denoted
by numerals 24, 40, 60 and 72, respectively. The central
station 10, for example, communicates with fixed remote
stations 12 through
16 via directional antennas 12a through 16a, respectively
(column 3, lines 17 through 35). “Each central station
transmits at a distinct frequency and each remote station
assigned thereto receives at the frequency of its assigned
central station and transmits at a different frequency, unique
to itself” (Abstract). Based upon a broad statement in Mack
(column 2, lines 3 through 7) that “[m]ore particular objects
of the invention are to provide improved transmission quality
monitoring and adaptiveness in a communication system itself
having improved set up time
. . . , ” the examiner concludes (answer, page 3) that “[i]t
would have been obvious to one of ordinary skill in the art at
the time the invention was made to modify the method of
handover of Menich et al. by including a plurality of cells
containing a plurality of transceiver units as taught by Mack
. . . . ”
