Field Tests
Throughout 2007, the Tedra™ device is being tested in underground environments with the attendance of caving exploration groups from different countries, as well as members of rescue and emergency groups.Villanúa (Huesca), 26th March 2007
“Esjamundo Caves (New Caves)”
See video of test
On 26th March the first public on-field presentation was held for Tedra™, the new digital device for underground communication. Those attending the demonstration included, among others, members of diverse Civil Guard Units, the Mossos d’Esquadra (Catalan police) underground city unit, the Basque government emergency department, Aragon speleo-aid, the Zaragoza fire brigade and the Spanish Speleology Federation.
The field test attended by BARRABES took place in the Esjamundo Cave, in Villanúa (Huesca). Reaching this cave by road is easy and there is a horizontal entrance to the cave which facilitates fast deployment of the team. Two groups were established; one accessed the inside of the cave while the other stayed on the surface to carry out communication tests with the other Tedra device at different distances.
The sudden change in climatic conditions (first rain and then snow), made access by car, to previously planned areas, complicated for the surface group. Communication was finally made from two areas at different distances: 450 and 800 metres. In spite of the less-than-perfect conditions of the terrain, wet ground caused by the rain and high level of the phraetic stratum inside the cave, communication was perfectly possible.

The test was carried out by the mountain rescue section of the Ertzaintza (Basque Autonomous Police) and communication was first made from the surface to the mid-point of the cave at 450 metres, then to the furthest point at 900 metres. This event made impact on the media (TV & newspapers) and their articles can be viewed here.
