Siemens S.A. Argentina has installed a long-distance radio relay network in the mountains of Northern Argentina, part of an ambitious program by private long-distance carrier Telecom Argentina to upgrade the region's telecommunications facilities. The network features both one of the world's longest radio hops (126 km), and one of the world's highest relay stations - perched atop the nearly 5000-meter high Cerro Esperanza in the Argentine Cordilleras.
