Abstract
An electromagnetic (RF) and light transparent enclosure having a perforated metallic wall. The enclosure is particularly adapted for an RF wireless tracking system, as a housing for the transmitter device or for a cargo container in or on which the transmitter device is positioned. The enclosure is optically transparent to ensure any photovoltaic device of the transmitter device receives sufficient photons or other energy to power the transmitter device. The RF transparent enclosure attenuates less transmitted and/or received signal at specific frequency bands.
