The architecture and operation of a wireless instrumentation bus based on the Bluetooth standard are presented together with a detailed characterization. The bus, via suitable wireless interface boards, allows measurement instruments equipped with standard RS232, IEEE488, universal serial bus, and local area network interface ports to be simply connected within the wireless area without any firmware modification. In addition, a comparison with traditional wired interface buses is carried out in terms of communication reliability and throughput with reference to some basic operating modes. Finally, the results of distance tests and a detailed evaluation of power consumption for each wireless interface module are reported. This will enable measurement system designers to evaluate the convenience of the solution for their application requirements.

Abstract

The architecture and operation of a wireless instrumentation bus based on the Bluetooth standard are presented together with a detailed characterization. The bus, via suitable wireless interface boards, allows measurement instruments equipped with standard RS232, IEEE488, universal serial bus, and local area network interface ports to be simply connected within the wireless area without any firmware modification. In addition, a comparison with traditional wired interface buses is carried out in terms of communication reliability and throughput with reference to some basic operating modes. Finally, the results of distance tests and a detailed evaluation of power consumption for each wireless interface module are reported. This will enable measurement system designers to evaluate the convenience of the solution for their application requirements.
