1. A lighting system, comprising:

  • luminaires, each respective one of the luminaires comprising;

    (a) a light source;

    (b) a driver circuit coupled to the light source;

    (c) a 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 configured for wireless communication;

    (i) via a lighting control network, over a first of two different wireless communication bands, of light source control operations over the first wireless communication band; and

    (ii) via a commissioning network with a mobile commissioning device, over a second of the two different wireless communication bands, of commissioning, configuration, or maintenance operations for the respective luminaire;

    (e) a memory accessible to the processor; and

    (f) programming in the memory which configures the 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;

    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) a 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 configured for wireless communication;

    (i) via the control network, over the first of two different wireless communication bands, of light source control operations over the first wireless communication band; and

    (ii) via the commissioning network with the mobile commissioning device, over the second of two different wireless communication bands, of commissioning, configuration, or maintenance operations for the control node;

    (e) a memory accessible to the processor of the control node; and

    (f) programming in the memory which configures the processor of the control node to transmit information based on the sensing signal for the light source control operations over the first of the two different wireless communication bands via the dual-band wireless radio communication interface system;

    wherein each dual-band wireless radio communication interface system comprises;

    a sub-gigahertz band radio transceiver for the wireless communications over the first band; and

    a two gigahertz or higher band radio transceiver for the wireless communications over the second band.
