Abstract: A process of determination of a percentage of glass surface to treat with a decoating process in a defined enclosed space in order to reach a predetermined level of electromagnetic reception and/or transmission at a predetermined frequency, using a database. The process contains the following: measurement of the inside and/or outside electromagnetic signal amplitude; calculation of an expected attenuation level; identification, in said database, of reference percentages of treated surface where the corresponding reference attenuation levels are inferior or equal to the expected attenuation level; determination of a percentage of glass surface to treat in the defined enclosed space corresponding to the identified reference percentage of treated surface where the corresponding reference attenuation level is minimum.

Abstract: An improved glazing unit extending along a plane, P, defined by a longitudinal axis, X, and a vertical axis, Z; having a width, DW, measured along the longitudinal axis, X, and a length, DL, measured along the vertical axis, Z, including a glass panel, a housing able to accommodate a communication device and an opening arranged on the glass panel. The present invention also discloses a communication system including a glazing unit, at least a 4G and/or 5G signal communication unit and a provider fixed station or active or passive repeater, which is placed at least at 1 m outside from the glazing unit, wherein the 4G and/or 5G signal communication unit is fixed to the glazing unit at the opposite side from the provider fixed station or active or passive repeater.

Abstract: A 4G and/or 5G signal communication unit is able to be attached to a glazing unit that includes housing with at least side parts and a cover. A communication device is fixed inside the housing and is surrounded by the side parts and the cover. The 4G and/or 5G signal communication device has at least one antenna. The housing includes a matching element. A communication system includes a glazing unit, at least the 4G and/or 5G signal communication unit and a provider fixed station or active or passive repeater, which is placed at least at 1 m outside from the glazing unit. The 4G and/or 5G signal communication unit is fixed to the glazing unit at the opposite side from the provider fixed station or active or passive repeater.

Abstract: An improved a glazing unit extending along a plane, P, defined by a longitudinal axis, X, and a vertical axis, Z; having a width, DW, measured along the longitudinal axis, X, and a length, DL, measured along the vertical axis, Z, including, at least a first outer glass panel having a S11 surface and a S12 surface and a second inner glass panel having a S21 surface and a S22 surface combined together while maintaining the two glass panels at a certain distance between the surface S12 of the first outer glass panel and the surface S21 of the second inner glass sheet. The glazing unit further includes a housing able to accommodate a 4G and/or 5G communication device and has an opening arranged on the second inner glass panel, the housing having been placed in the opening.
