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.

1. A wireless communication system in a fueling environment at a fuel dispensing site, comprising: a first sensor adapted to detect a condition in the fueling environment;a first wireless transceiver associated with said first sensor;a repeater positioned in the fueling environment for repeating transmissions from the first wireless transceiver; anda second wireless transceiver associated with a site communicator at the fuel dispensing site, wherein said site communicator receives data from said first sensor through said first wireless transceiver, said repeater, and said second wireless transceiver. 2. The wireless communication system of claim 1, wherein said first sensor is selected from a group consisting of: a tank probe and a fuel dispenser sump probe. 3. The wireless communication system of claim 1, wherein said second wireless transceiver broadcasts a beacon signal. 4. The wireless communication system of claim 3, wherein said first wireless transceiver receives said beacon signal and synchronizes thereto. 5. The wireless communication system of claim 1, wherein said first wireless transceiver is powered by a battery. 6. The wireless communication system of claim 5, wherein said battery is recharged via solar energy. 7. The wireless communication system of claim 1, wherein said site communicator is selected from a group consisting of: a tank monitor and a site controller. 8. The wireless communication system of claim 1, wherein said first wireless transceiver initially transmits sensor data and said site communicator receives said sensor data from said first wireless transceiver and subsequently, after a predefined delay, from said repeater. 9. The wireless communication system of claim 1, wherein said first wireless transceiver is powered by an AC power source. 10. The wireless communication system of claim 1, wherein said repeater is positioned on a fuel dispenser. 11. The wireless communication system of claim 1, wherein said repeater is positioned on a canopy. 12. The wireless communication system of claim 1, wherein said repeater receives a signal from said first wireless transceiver. 13. The wireless communication system of claim 1, wherein said first wireless transceiver communicates at a frequency selected from a group consisting of: 900 MHz, 866 MHz, and 433 MHz. 14. The wireless communication system of claim 1, wherein said site communicator uses said data. 15. The wireless communication system of claim 1, further comprising a plurality of repeaters positioned in the fueling environment. 16. The wireless communication system of claim 15, wherein said plurality of repeaters repeat a transmission including the data as received from said first sensor to the site communicator. 17. A method of reporting probe data in a fueling environment at a fuel dispensing site, said method comprising: receiving sensor data at a first wireless transceiver from a sensor in the fueling environment;wirelessly transmitting the sensor data, creating transmitted sensor data;receiving at a repeater a transmission from the first wireless transceiver comprising the transmitted sensor data;repeating the transmission comprising the transmitted sensor data via the repeater; andreceiving the transmitted sensor data at a site communicator at the fuel dispensing site via a second wireless transceiver. 18. The method of claim 17, wherein receiving sensor data comprises receiving sensor data from either a tank probe or a fuel dispenser sump probe. 19. The method of claim 17, further comprising broadcasting a beacon signal from the site communicator. 20. The method of claim 19, further comprising detecting, at the first wireless transceiver, the beacon signal. 21. The method of claim 20, further comprising synchronizing the first wireless transceiver to the beacon signal. 22. The method of claim 17, further comprising powering the first wireless transceiver with either a battery or an AC power source. 23. The method of claim 17, further comprising powering the repeater with either a battery or an AC power source. 24. The method of claim 17, further comprising sending, from the site communicator, an acknowledgement signal upon receipt of the transmitted sensor data. 25. The method of claim 24, wherein repeating the transmission from the repeater does not occur if the repeater receives the acknowledgement signal. 26. The method of claim 24, wherein repeating the transmission from the repeater occurs regardless of whether the repeater receives the acknowledgement signal. 27. The method of claim 17, wherein receiving the transmitted sensor data comprises receiving the transmitted sensor data at the site communicator from the first wireless transceiver and the repeater. 28. The method of claim 17, further comprising positioning the repeater on a fuel dispenser. 29. The method of claim 17, further comprising positioning the repeater on a canopy in the fueling environment. 30. The method of claim 17, wherein wirelessly transmitting the sensor data comprises wirelessly transmitting at a frequency selected from a group consisting of: 900 MHz, 866 MHz, and 433 MHz. 31. The method of claim 17, wherein repeating the transmission from the repeater comprises delaying a predetermined amount of time before repeating the transmission. 32. The method of claim 17, wherein receiving the transmitted sensor data at a repeater comprises receiving the transmitted sensor data at a plurality of repeaters. 33. The method of claim 32, further comprising repeating transmission of the transmitted sensor data from each of the plurality of repeaters. 34. A method of reporting probe data in a fueling environment at a fuel dispensing site, said method comprising: receiving sensor data at a first wireless transceiver from a sensor in the fueling environment;wirelessly transmitting the sensor data, creating transmitted sensor data;receiving the transmitted sensor data at a repeater;retransmitting the transmitted sensor data from the repeater;receiving the transmitted sensor data at a site communicator at the fuel dispensing site via a second wireless transceiver; andsending, from the site communicator, an acknowledgement signal upon receipt of the transmitted sensor data. 35. The method of claim 34, wherein retransmitting the transmitted sensor data from the repeater does not occur if the repeater receives the acknowledgement signal. 36. The method of claim 34, wherein retransmitting the transmitted sensor data from the repeater occurs regardless of whether the repeater receives the acknowledgement signal.
