1. A network node that is configured for use in a wireless packet-hopping network that includes a plurality of network nodes and at least one control node, comprising:

  • a transceiver, a threshold comparator that is configured to compare a signal strength of a received signal from the transceiver to a threshold level to provide a comparator output signal, a controller that is configured to enable transmission of packets from the transceiver based on the comparator output signal, wherein;

    the controller is further configured to;

    receive one or more commands from the at least one control node, and adjust the threshold level based on the commands from the at least one control node, and the controller is further configured to enable reception of packets by the transceiver based on the comparator output signal, the network node further including a dimming ballast that is configured to control a lamp, and wherein the controller is further configured to control the dimming ballast based on information contained in one or more packets.
