Evaluation of EMF inside Motorcycle Helmet with installed Bluetooth Communicator under Laboratory Condition

Evaluation of electromagnetic field (EMF) inside motorcycle helmet with Bluetooth communicator is the main goal of the paper. Measurement was made under the laboratory condition using two helmets with integrated Bluetooth communicator set in intercom mode for three cases, helmet distance set to 500mm without communication, same distance with communication and for distance of 2500mm with ongoing communication. As measurement setup BK PRECISION 2650A spectral analyser together with Rohde & Schwarz antennas were used.
