Abstract: An enhanced wireless network system including a visible-light transparent, transmission shielding component for application to or incorporation in windows to create a shielded wireless network operation area. The shielding component enhances network performance by substantially reducing extraneous electromagnetic interference and enhances network security by substantially containing electromagnetic transmissions to desired areas. The shielding component may comprise several alternating layers of metal, to substantially attenuate transmissions to varying degrees, including attenuation of 20 to 50 db in the 1 MHz to 100 GHz range and beyond, while simultaneously permitting substantial transmission of visible light (such as 15-55%).
