Abstract
A method is disclosed for determining a connectivity status of radios in a coverage group. Each coverage group includes radios configured to transmit and receive range messages on a channel and a timeslot. Each radio in the coverage group is configured to generate a range message and to transmit the range message to each other radio in the coverage group. Each radio in the coverage group is also configured to receive, from each other radio in the coverage group, a range message generated by each other radio. Based on the range message received from each other radio, each radio is configured to determine bi-directional connectivity between the receiving radio and the radios that sent the D-ARTS messages. The determined bi-directional connectivity status is between each radio and each of at least two other radios in the coverage group.
