Appeal No. 2000-1703
Application No. 08/963,545
BACKGROUND
Appellants’ invention relates to a building control system
including individual control units (non-master nodes) and a
central control unit (master node) for wirelessly communicating
control signals between the nodes (specification, page 7). When
a message is received in a non-master node, the destination
address is checked to determine if the signal is directed to that
node (specification, page 18). If that node is not the intended
recipient, the message is repeated for the intended node
(specification, page 19).
Representative independent claims 20 and 23 are reproduced
below:
20. A building network comprising, within a building:
a master node for wirelessly transmitting information
at a power level;
a first non-master node, disposed within a transmission
range of the master node operating at the power level, for
wirelessly repeating the information;
a second non-master node, disposed outside the
transmission range, for receiving the information repeated
by the first non-master node.
23. A node for use in a building network including
transceiver means suitable for receiving and
transmitting wireless communication of information either
