Terms of Reference

SG 5 is responsible for studies related to electromagnetic compatibility (EMC) of telecommunication systems including to avoid hazard to human beingsLead SG for: – Area 0 “Generic”, Domain 15 “ElectroMagnetic

Compatibility (EMC), Protection and Safety”


4


Highlights of achievements (I)

SG 5’s leadership on the management of electro-magnetic interference to telecommunication systems from power systems has been consolidated by:

– New Recs. K.54 and K.68 – Revision of Volume V and VI of the

Directives “Protection of telecommunication lines against harmful effects from electric power and electrified railway lines”


5


Highlights of achievements (II)

SG 5’s leadership on the standardization of equipment resistibility has been consolidated by :– Revision of Recs. K.20, K.21, K.44 and K.45

as well on lightning protection of telecommunication systems by :– New Recs. K.67, K.71 and K.72 – Revision of Recs. K.46 and K.47


6


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


7


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


8


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


9


Future Work (I)

Continuation of Questions dealing with:– Home Network– Security of telecommunication and information

systems regarding electromagnetic environment

– EMC requirements for Information Society– Interference on telecommunication systems

from power systems– Resistibility and Safety requirements


10


Future Work (II)

Continuation of Questions dealing with:– Lightning protection of telecommunication

installations– Human Exposure to Electromagnetic fields

from telecommunication installations– Earthing and Bonding techniques– EMC requirements for telecommunication

equipment

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.
