1. A mesh network comprising:

  • multiple nodes including a plurality of star nodes and a plurality of routing nodes, each star node configured to transmit and receive wireless signals, each routing node configured to transmit and receive wireless signals for communication with at least one of the star nodes;

    wherein each star node is configured to communicate with at least one of the routing nodes using a plurality of different frequencies; and

    wherein each routing node is configured to become available for communication with at least one of the star nodes based on a time and frequency schedule that is coordinated between multiple ones of the routing nodes and at least one of the star nodes;

    wherein the coordinated time and frequency schedule defines at least one randomized sequence of different frequencies used; and

    wherein the coordinated time and frequency schedule is coordinated with other routing nodes and indicates a start time for each frequency.
