Find below information about the use of radio frequencies and interferences, as well as the granting of rights and the supervisory role of EETT.
Radio frequencies are widely used by companies, state authorities, organizations and individual users for the provision of services or for serving their own needs. A typical example is the use of radio frequencies by:
- Mobile telephony providers for the provision of services to their subscribers.
- Broadcasting network providers for broadcasting television programs to the general public.
- Radio stations for transferring the signal from the point of production to the general public.
- The Hellenic Civil Aviation Authority (CAA) for the communication of aircrafts with ground operations, as well as by other state bodies and agencies (e.g. National Center of Emergency Care-EKAV and Fire Department) to cover their communication needs.
- Professionals (e.g. radio taxi service) to meet their communication needs.
Radio frequencies are also used, for instance, for the operation of cordless phones and wireless networks (WiFi), as well as remote control systems (alarms, garage doors, etc.).
Interference is any signal transmission that:
- Disrupts wireless communications, such as mobile telephony, television and radio broadcasting, telecommand, WiFi networks and radio amateur stations.
- Creates problems to the operation of wired networks and electronic/electrical equipment, such as corded phones, speakers, video door intercoms, modem/router.
