Appeal No. 2002-1318
Application No. 08/693,662
BACKGROUND
Appellants' invention relates to a method and apparatus for
using unintended radio frequency propagation. An understanding
of the invention can be derived from a reading of exemplary claim
1, which is reproduced as follows:
1. A repeater for coupling data from a first power line to a
second power line where the power lines are each a data
communications medium comprising:
a radio frequency receiver tuned to sense data signals
propagated from the first power line, the first power line
serving as a first data communications medium for a plurality of
first nodes; and,
a power line transmitter coupled to the radio frequency
receiver and the second power line, the second power line serving
as a second data communications medium for a plurality of second
nodes, so that the data signals originating from the first data
communications medium and sensed from the first power line by the
receiver are coupled to the power line transmitter for the second
data communications medium without the use of an RF transmitter
on the first power line.
