Measurement location in the center of Tripolis

Field strength (V/m) for different frequency bands (Project: ‘EU/GR-INTENTION’ 2013)

Projects:

  • Field measurements in urban and suburban environments,

    BSc Thesis completed in 2014. The level of the electromagnetic radiation was studied in urban, suburban and rural
    environments in the area of Tripolis. The results were compared to the exposure limits set by the Greek legislation and to those proposed by the Bio-Initiative report. 

Narrowband Propagation Measurements

Narrowband propagation measurements for outdoor and indoor environments.

Power model for the corridor (Tsesis: Mpasiaka-Tsirivakou 2012)

Projects:

  • Indoor Power Measurements

    BSc Thesis completed in 2012. In this thesis extensive indoor power measurements were held in the first floor of the Department’s building in order to determine an indoor path loss prediction model for this area.

  • Study of antennas radiation pattern in realistic environment
  • Electromagnetic radiation measurements for GSM-900 networks
