Highlights of achievements (III)
In the field of human exposure to electromagnetic fields (EMFs):– New Rec. K.70, together with associated EMF
estimator software, gives guidance on mitigation methods for reducing the radiation level from radio-communication installations in order to comply with exposure limits
– Recs. K.52 and K.61 on EMFs calculation and
measurement methods have been revised

Highlights of achievements (IV)
In the Home Network field: – The new Rec. K.74 provides EMC,
Resistibility and Safety requirements for home network devices that mainly have the function of telecommunication
– In the new Rec. K.75, Manufacturers, Network Operators and Test Houses can find classification of telecommunication equipment interfaces for the application of standards on resistibility and safety

Highlights of achievements (V)
Protective Components characteristics are given in the new Recs. K.65 and K.69 and revision of Recs. K.12 and K.30The new Recs. K.66 and K.73 are in the field of Earthing and Bonding, whereas the new Rec. K.76 and the revision of the Rec. K.48 are in the EMC field The deployment of broadband services has increased the risk of interference of wire-line telecommunication networks with radio services. The revision of Rec. K.60 deals with the management of this risk

Thank you!Mr Roberto Pomponi earned a degree in Electrical
Engineering from the Polytechnic of Turin (Italy) in 1972 and in the same year he joined TILAB (formerly CSELT, Centro Studi e Laboratori Telecomunicazioni in Turin, Italy), where he has carried out activities on protection of telecommunication installations against lightning, electromagnetic interference and safety. He has been professor of EMC seminars at the Polytechnic of Turin, University of Ancona and at High School of the Telecom Italia Group. He is Chairman of the some Italian Technical or Sub-Technical Committees and is Chairman of ITU-T SG 5.
