“…Another, more visual way of filling the public information gap would be the use of a heat map, an easily comprehensible graphical representation of the magnitude of the RF-EMF exposure over an urban, suburban, or rural area. Naturally, heat maps can also be constructed using RF-EMF simulators, or from non-measurement-based models like the ones by Beekhuizen et al (2013), Breckenkamp et al (2008), Bürgi et al (2008Bürgi et al ( , 2010, Elliott et al (2010), Frei et al (2009b), and Neitzke et al (2007), by calculating the exposure at arbitrary locations, probably using a uniform grid with a resolution of choice. However, these approaches are heavily dependent on accurate data, e.g., base station parameters, building coordinates, building heights, etc., data which is seldom readily available.…”
