1. A lighting system, comprising:

  • intelligent luminaires, each respective one of the intelligent 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 two way wireless communication for;

    (i) unicast and multicast communication via a control network, over a first of two different wireless communication bands, of control and systems operations information, during luminaire operation and during control network operation over the first wireless communication band; and

    (ii) point-to-point communication via a commissioning network with a mobile commissioning device, over a second of the two different wireless communication bands, of commissioning or maintenance information other than the control and systems operations information;

    (e) a memory accessible to the processor; and

    (f) programming in the memory which configures the processor to control operations of the respective intelligent luminaire, including the communications over the two different wireless communication bands via the dual-band wireless radio communication interface system;

    a standalone intelligent control node, comprising;

    (a) a switch or a detector;

    (b) a sense circuit responsive to the switch or a 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 two way wireless communication for;

    (i) unicast and multicast communication via the control network, over the first of the two different wireless communication bands, of control and systems operations information, during illumination operation of the system and during control network operation over the first wireless communication band; and

    (ii) point-to-point communication via the commissioning network with the mobile commissioning device, over the second of the two different wireless communication bands, of commissioning or maintenance information other than the control and systems operations information;

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

    (f) programming in the memory which configures the processor of the standalone intelligent control node to transmit information based on the sensing signal 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.
