  The reduction of the average charge per count in the gas along with the
capability to discriminate very small signals from noise can allow an efficient
and long-term Resistive Plate Chamber detector operation in high radiation
background environment. This goal has been reached during the R&D program of
the BIS78 upgrade project of the ATLAS detector at LHC through the deep
integration of a fast (100 ps peaking time) and sensitive (as small as 100 `V
threshold) Front- End electronics (FE) with a very large size detector
structure. This innovative RPC integration concept pivots on a newly conceived
faraday cage, embedding the readout strips and the FE, tightly wrapped around a
1 mm gas gap RPC with 1.2 mm thick electrodes, as a fully independent singlet
structure. We studied the performance of BIS78 production triplet chambers,
made of 3 independent singlets of 2 <2, each providing a 2D space and time
information, showing a minimum threshold achievable of 2 pC of average charge
per count produced inside the gas gap. We show that these chambers grant a
record combined performance of better
