Abstract
A scheme of identifying nonfunctional two-way radios from among a known group of two-way radios expected to be operating within a region may include establishing a corresponding window of time for each of the two-way radios expected to be operating within the region. For each of the established windows of time, a transmission from the corresponding radio is awaited. If, for a particular radio, no transmission is detected within its corresponding window of time, the absence of the transmission is recorded. Finally, if, for a particular radio, the number of times absence of transmission has been recorded exceeds a threshold, the particular radio is identified as nonfunctional.
