1. A monitoring unit for wireless communication with a plurality of self-contained breathing apparatus (SCBA) units configured to form a network, the monitoring unit comprising a communication interface and processing circuitry, the processing circuitry configured to:
receive, via the communication interface, a plurality of updates from each of the SCBA units, each update including information indicating at least one communication link quality to at least one other SCBA unit;
determine at least one distance from each SCBA unit to at least one other SCBA unit that is one hop away in the network based at least in part on the communication link quality;
cause the determined at least one distance to be displayed;
determine that a SCBA unit has triggered an alarm;
determine at least one other SCBA unit within a predefined distance from the SCBA unit that triggered the alarm; and
cause the at least one other SCBA unit that is within the predefined distance to be displayed.
