Abstract
A wireless telecommunication system for an equipment in an underground structure is disclosed. The system comprises a metal cover fitting in an opening of the underground structure while being supported by a shoulder. A porthole is formed in the cover. The porthole has a lens in plastic material letting radio waves pass. A cradle hangs across the opening. An antenna arrangement is mounted on the cradle and extends near and in alignment with the lens. A radio transceiver connects to the antenna arrangement and to the equipment in the underground structure to establish a wireless telecommunication with the equipment via the antenna arrangement and the lens.
