A fueling environment is equipped with leak detection probes and liquid level probes. Each of the probes is associated with a wireless transceiver. The wireless transceivers send probe data to a site communicator wireless transceiver. To ensure that the site communicator receives the probe data, repeaters are used within the fueling environment. The repeaters receive the probe data, and some period of time after the sensor transceivers stop transmitting, the repeaters retransmit the probe data to the site communicator. The site communicator discards duplicative information and processes the probe data as needed.
