Abstract

A solution for communicating between devices located within and outside of an effective Faraday cage volume is provided. An enclosure structure forming the effective Faraday cage volume can be used as an antenna for a transceiver of a wireless device located within the Faraday cage volume. An antenna connector of a transceiver of the wireless device can be physically connected to the conductive material of the enclosure structure using any solution. The enclosure structure can transmit wireless signals generated by the wireless device external of the enclosure structure and/or transmit external wireless signals to the transceiver of the wireless device for processing by the device.
