Abstract
The invention relates to a heatable glazing comprising an electrically conductive coating and a data transmission window. The data transmission window comprises a plurality of grids made by ablations in the electrically conductive coating and at least one break line between adjacent grids. At least one of a width 'a' of the grids and a distance 'b' between adjacent grids is selected to maximise transmission of a predetermined frequency of electromagnetic radiation and to reduce the formation of hot spots. Preferred embodiments conform to a standard size of an ERTICO window and a frequency range from 5 GHz to 6 GHz.
