What are radio waves and how does mobile telephony work?

During the past ten years, several hundred studies have been conducted using mobile phone signals specifically.

All mobile phones are designed and tested for compliance with national and international RF exposure standards and regulations.

Radio base stations are needed for transmitting and receiving radio signals to and from mobile phones.

Electronic devices can be sensitive to electromagnetic fields. The phenomenon is called electromagnetic interference.

There exist a number of national and international regulations, standards and recommendations dealing with exposure to radio frequency electromagnetic fields.
