2The ICT revolution
- By end 2014, there will be
- 3 billion Internet users,
- two-thirds of them coming from the developing
world - the number of mobile-broadband subscriptions will
reach 2.3 billion globally (5 of these
subscriptions are expected to be in the
developing world) - mobile-cellular subscriptions will reach almost 7
billion by end 2014

3The issue
- Lack of regulation and/or
- non-compliance...
The electromagnetic fields are unknown and
undetectable for people
Lack of communication and information to
citizens
It can generate a lack of trust, which may
become fear
4Regulation of non-ionizing radiations
Exposure standards Specifications that limit the
exposure of people to the Electromagnetic fields
(EMF)
Emission standards Specifications that limit the
emission of electromagnetic fields (EMF) from the
devices
5How can global standards help
- Facilitate compliance with international
standards - Strengthen collaboration among stakeholders
- Ensure transparency
- Enhance communication with citizens

11EMF assessment methods
Calculations or measurements?
