Description

Studies of Electromagnetic environment is a work line in which measurements of the electromagnetic environment are made due to radio frequency emissions, the registration of values in electric and magnetic fields in the following environments are considered particularly important:

Studies of Electromagnetic environment in open spaces: Averages and high frequencies: Frequencies rank between 100 KHz and 6 GHz.

Field measurements in broadband are carried out, travelling around the built-up areas in the center of villages of interest. Once the broadband study is finished, we take measurements on narrowband for middle and upper frequencies in the most interest points.

Low frequencies: the measurement of electromagnetic low frequencies (ELF) is covered, emitted by various sources (Power transformers, electrical substations, wiring, high-voltage power lines, etc. ) in population centers. The margin of frequencies of interest for these measurements is the 1Hz to 100KHz range, specially the margin of frequencies around 50Hz, which is the frequency of the Spanish's electrical grid, and its main harmonics.

Study of the electromagnetic environment in enclosed spaces: WiFi and mobile phone: Study of the electromagnetic environment generated by radiofrequency emissions inside public buildings, focused on wireless communication technology WiFi and mobile phone. In these measurements specifically, carried out in public buildings of Castilla y León, the emissions of GSM, DCS, UMTS ans WiFi technologies have been analysed in narrow band, namely, in the bands of associated frequencies ranging from 900MHz and 2,5 GHz.

In hospitals: Study of the electromagnetic environment generated by radiofrequency accross the entire magnetic spectrum, from 1Hz to 6GHz in hospitals.
