Rai Way has always recognised the importance of verifying the quality of transmitted signals, the use of the spectrum and the evaluation of the impact of electromagnetic fields.
The control centres in Monza and Sorrento are responsible for monitoring the compliance of transmission services with current laws in Italy and abroad. They are centres of excellence and are recognised leaders in their field at a global level.
The Centres are equipped with laboratories furnished with advanced professional equipment dedicated to the development of procedures, methodologies, and measurement systems to assess user reception quality and monitor the signals transmitted by the company's television and radio transmitters. The laboratories are also used to assess receiver performance and latest generation measurement tools available on the professional market, as well as to calibrate company equipment.
The Centres’ workforce is composed of technicians with highly specialised knowledge of the radio frequency sector. This proficiency is maintained at the highest level thanks to the participation in the study groups of some of the leading national and international organisations in the field (ITU-R, EBU, Cenelec, CEI, BNE).
Rai Way has access to an extensive monitoring system (approximately 50 stations) designed, developed and managed by the Control Centres. This system provides detailed information on the user receiver status of radio and television signals.
Launched in the early 1990s as the “Light Network” and designed to carry out simple checks, the system has since developed into an integrated and transversal monitoring system and is used to monitor various company activities such as the control of broadcasts by Rai Way and private companies in sites with NIR (non-ionising radiation) issues and the evaluation of KPIs in conjunction with data from other company systems.
The network has a hierarchical structure and enables the detection of issues on the broadcasting network (on a continuous basis, through random sampling, at predefined or scheduled intervals, etc.) or situations that depend on the system in use and the surrounding conditions.
In addition to being widely used for internal purposes, the control network is able to provide data to Clients. Rai Way offers a “turnkey” control service including the real-time detection of significant events and regular Reports on the principle parameters under observation.
As well as the routine control measures, the network is also used for experimental analysis and specific studies, as well as to support system surveillance.
NIR Evaluations: Electromagnetic Impact Assessments
The electromagnetic fields generated by radio and television systems are classified as NIR (Non-Ionising Radiation) as they do not possess sufficient energy to ionise matter. However, in the last few decades public interest in the effects of electromagnetic radiation on human health has increased significantly, resulting in the need to assess the exposure of the local population and the workforce to electromagnetic radiation.
Changes in legislation regarding exposure of the public and the workforce to electromagnetic radiation has led to the development of specific industry regulations and the need to measure both very low and very high levels of radiation, a process which requires specialised equipment suitable for the purpose.
Rai Way is one of the most experienced and skilled companies in Italy in the management of matters relating to the health impacts of electromagnetic radiation and its Control Centres are recognised as Centres of Expertise for activities in this field. The Centres have played a primary role in the development of equipment and the definition of appropriate operating conditions and measurement methods thanks to participation in studies, experiments and study groups focused on the identification of national and international standards (CEI, Cenelec).
Thanks to long-standing experience in the field, the Centres have developed expert knowledge of the measurement techniques for the aforementioned levels, defined exclusively by Italian legislation regarding public exposure to radiation (electric field, magnetic field and power density).
