Appeal No. 95-5053
Application 08/048,188
from 824-894 mHz" (col. 2, lines 48-51). The admitted prior
art of appellant's figure 3 shows that the cellular handset
transmits in the frequency band of 824-849 MHz and receives in
the frequency band of 869-894 MHz.
Rose teaches that conventional prior art cordless
telephones used a radio frequency band usually in the 46 and
49 MHz bands and used Narrow-Band Frequency Modulation (NBFM)
(col. 1, lines 27-35), but that revised FCC regulations
authorized cordless radio channels in the frequency band of
902-928 MHz (col. 2, lines 55-61). Rose teaches a cordless
telephone where the handset and the base unit communicate
using frequency shift keying (FSK) in the 902-928 MHz band
where, for example, the base unit operates in the frequency
band of 905.6-907.5 MHz and the handset operates in the
frequency band of 925.5-927.4 MHz (col. 4, lines 50-54).
Thus, the handset in Rose transmits in the frequency band of
925.5-927.4 MHz and receives in the frequency band of
905.6-907.5 MHz.
The examiner concludes that it would have been obvious to
one of ordinary skill in the art to modify the
cordless/cellular telephone of Gillig to use the 900 MHz band
