The Electromagnetic Monitoring Systems (MonitEM) are continuous monitoring systems that make it possible to check continually the strength of the fields generated by electromagnetic radiation emitters (antennas, power lines, etc.) and publish the data obtained over the Internet in regular automatic reports. The two basic aims are: The systems consist of a number of monitoring devices located near the electromagnetic field sources (antennas) or in places of special importance (schools, hospitals, etc.) and remotely controlled from a computerized control center. The monitoring devices sample the electromagnetic field continuously (all day, every day), store the measurements temporarily and transmit them at regular intervals to the control center.
The electromagnetic field is measured using a triaxial isotropic probe, to allow measurement of the full composite field arriving from all directions. The computerized control system has been designed for direct integration with the Internet, allowing an authorized user to check the stations from anywhere with a connection. Likewise, the data collected can be published so that any interested party can consult it. The continuous monitoring systems have been developed by Wavecontrol in co-operation with the Electromagnetic Compatibility Group at the Technical University of Catalonia.
