Axion
A challenger with pooled skills
A new entrant to the Spanish broadcasting market, Axión launched regional DT in Andalusia in 2005 and is now the second largest audiovisual broadcasting operator in the country. In the financial year 2007-2008, the Andalusian operator consolidated its positions in the audiovisual sector and carried out major developments in the telecommunications sector. The renewal of the DT broadcasting contract with television station RTVA brings Axión's regional coverage to 85% from 13 sites. In terms of telecoms, Axión took part in the launch of Yoigo, the fourth-largest mobile operator in the country. Expanding its expertise across the value chain and offering integrated solutions, Axión won a facilities maintenance contract with Correos Telecom in four provinces and independent cities (Andalusia, Extremadura, Ceuta and Melilla), covering 17 urban and 31 rural sites. In order to better assist its clients in the move towards mobile technology and digital convergence, Axión conducted a series of pilot programs this year. The company set up an experimental mobile TV network in Seville, thereby honing its skills in aspects such as the architecture of the sites involved, the equipment required as well as the operating costs associated with the commercial deployment of the service. In terms of digital radio, it conducted an experiment into DR M with Cadena Ser, one of Prisa Group's radio stations, in order to accurately assess conditions for simulcasting.
