Appeal 2007-1481
Application 09/915,091
We affirm.
Appellants’ invention relates to identifying sufficient bandwidth
which is free of interference for use in wireless communications. Appellants
passively monitor a plurality of frequency bands, and select a wide
frequency band made up of a selected plurality of frequency bands judged to
be free of interference.
Claims 1 and 13 are exemplary:
1. A method of selecting a plurality of frequency bands for use
in a desired wireless communication from among a plurality of
frequency bands available to be used for the desired wireless
communication, comprising:
passively monitoring the plurality of frequency bands to
determine interference information for each of the frequency bands;
combining the interference information of said each of the
frequency bands to produce a signal quality indication; and
selecting the plurality of frequency bands for the desired
wireless communication in response to the signal quality indication.
13. A wireless communication station, comprising:
an antenna for use in wireless communications;
a band selection controller coupled to said antenna for selecting
a frequency band for use in a desired wireless communication from
among a plurality of frequency bands available to be used for the
desired wireless communication;
said band selection controller operable for passively monitoring
at least one of the available frequency bands to determine whether the
at least one frequency band is acceptable for the desired wireless
communication;
