Claim Text:
1. A fueling environment communication system for providing high bandwidth communication between a first location in a fueling environment and a plurality of forecourt devices remote from said first location via a plurality of existing field wiring extending between said first location and respective of said forecourt devices, said communication system comprising: a back room communication module having a first plurality of Ethernet ports for connection to external devices using Ethernet communication and a second plurality of Ethernet ports; said back room communication module further comprising a plurality of modulation interface devices each connected on a first side to a respective one of said second plurality of Ethernet ports, said modulation interface devices operative to convert between a modulated high frequency signal and an Ethernet signal; a combiner module having a high pass filter connected to each of said modulation interface devices on a second side thereof to pass said modulated high frequency signal; said combiner module having a low pass filter through which low frequency legacy data can be passed and combined with said modulated high frequency signal to produce a plurality of combined signals to be passed to respective of said forecourt devices; and said combiner module connectable via said plurality of existing field wiring to communicate said plurality of combined signals with respective of said forecourt devices in point-to-point fashion in respective field wiring.
