1. A system for monitoring a tool comprising:
- a portable tightening tool locatable at a work point and including a microprocessor unit for management and measurement of tool operation parameters and a transponder unit; and
a monitoring and control station having at least one decoder for communication with the transponder unit of the tool, the decoder having an antenna that can generate a signal over a predetermined limited range in order to enable real time communication between the tool and the station, wherein the antenna of the decoder is in juxtaposition to the work point so that the tool at the work point is within the predetermined generated signal range; and
wherein the microprocessor unit of the tool receives tightening parameters from the station through the transponder and the microprocessor unit of the tool sends to the station through the transponder measurement data taken by the tool when enabled within the predetermined signal range generated by the decoder antenna.
