In order to take into account the precautionary idea of health in the construction of mobile radio transmitters on community-owned residential complexes or land, the following procedure for the future installation of mobile communication systems in the context of private law contract design between the municipality of Vienna as a house and landowner and the mobile operators decided:
If the mobile network operator plans to build a mobile radio system on a building in the municipality of Vienna, the latter must provide a calculation in which it must demonstrate that the optimization value for the power density of 100 mW / m2 in the building is not exceeded. This optimization value must be adhered to by all residents of this transmission system and, of course, also in the homes of the residents of the house on which the system is installed.
Following the licensing by the Federal Regulatory Authority (September 2010), which enabled the expansion of LTE mobile technology to mobile operators, the implementing provision for the approval of the construction of mobile stations on the properties of the City of Vienna and Wiener Wohnen was revised.
This procedure refers only to the construction of mobile radio systems on urban residential buildings or land, since only there the city of Vienna can conclude private-law agreements with the operators. Due to the current legal situation, compliance with the optimization value is only possible in the context of private law contracts between the respective property owners and the mobile network operators, as the construction of these facilities is (except for a few exceptions) without a license. The commission was not only involved in the implementation of this voluntary approach by the City of Vienna to adhere to the optimization value, but is also involved in the assessment of the calculations to be submitted by the mobile network operators. This approach by the City of Vienna is a responsible step in the direction of a sufficient consideration of the health protection and the concerns of the residents regarding mobile radio systems.
