Video Tedra™

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 was carried out by Siemens and the Zaragoza University Hostile Environment Technology Group in the Esjamundo cave, in Villanúa (Huesca). Here, you can view the video of the first field-test, together with images showing some of the main characteristics: reduced installation time, low weight, high mobility and high quality communication.
