Claim of US Patent No. 10,172,219

1. A lighting system, comprising:a lighting control group including lighting control group members that are connected together over a lighting control network, one of the members being designated as a lighting control group monitor;
some of the lighting control group members are luminaires, each respective one of the luminaires comprising:
(a) a light source;
(b) a driver circuit coupled to the light source;
(c) at least one processor coupled to the driver circuit and configured to control light source operation via the driver;
(d) a dual-band wireless radio communication interface system for communicating over two different wireless communication bands, including:
(i) a first transceiver configured for wireless communication via the lighting control network over a first wireless communication band of the two different wireless communication bands, related to light source control operations, over the first wireless communication band; and
(ii) a second transceiver configured for wireless communication via a second network, over a second of the two different wireless communication bands, related to commissioning, configuration, or maintenance operations;
wherein respective frequencies of the two different wireless communication bands differ by at least a factor of two (2);
(e) at least one memory accessible to the at least one processor; and
(f) programming in the at least one memory which configures the at least one processor to control operations of the respective luminaire, including the communications over the two different wireless communication bands via the dual-band wireless radio communication interface system;
wherein at least one of the lighting control group members or the lighting control group monitor is a control node, comprising:
(a) a switch or a detector;
(b) a sense circuit responsive to the switch or the detector to generate a sensing signal;
(c) at least one processor coupled to the sense circuit and configured to receive and respond to the sensing signal;
(d) a dual-band wireless radio communication interface system including:
(i) a first transceiver configured for wireless communication via the lighting control network of light source control operations, over the first wireless communication band; and
(ii) a second transceiver configured for wireless communication via the second network of commissioning, configuration, or maintenance operations, over the second wireless communication band; and
(e) at least one memory accessible to the at least one processor of the control node; and
(f) programming in the at least one memory which configures the at least one processor of the control node to transmit information based on the sensing signal for the light source control operations over the first communication band via the dual-band wireless radio communication interface system.
