1 ITU-T Workshop Human exposure to electromagnetic fields (EMFs) Mobile and Base Station standards developed by CENELEC Joe Wiart Phd France Telecom R&D CENELEC TC106x WG1

2 Outline CENELEC WG1 overview Mobile standards Base stations standards

3 Base station and mobile: 8 CENELEC standards WG1 dedicated to mobile and base station WG is working since WG has drafted 8 standards Mobile standards Handsets compliance EN50360 & EN50361 Base station Putting base stations on the market EN50483, EN50484 & EN50485 Putting base stations into service EN50400, EN50401 Market enforcement tool (in situ) EN50492

4 RTTE directive Product and basic CEN,CENELEC & ETSI were mandated by the Commission to develop a comprehensive set of Harmonised Standards for the R&TTE Directive in 1999 HS don t require transposition in national standards, but give presumption of conformity directly after publication in the OJ The list of harmonised standards in the context of the RTTE Directive have been published in the OJ

5 Mobile Basic and product standards for handset Adopted by CENELEC in 2000 Product Standard published in OJEC in 2001 Based on ES Head phantom and liquid definition Test positions and protocol Uncertainty estimation Range : 300 MHz to 3 GHz The maximum SAR average over a cube of 10 grams is compared to the related limits

6 Mobile New usages and technologies CENELEC and IEC The EN50360 has been transferred to IEC in The IEC improved the document The IEC replaced the EN50360 in 2006 For new usages and higher frequencies: No specific work in CENELEC Work in performed in IEC ( )

7 Put Base Station on the market Basic and product standards to demonstrate the compliance of the product when it is put on the market EN 50383, EN and EN50385 Adopted by CENELEC in 2001 EN is published in OJCE in 2002 Measurement and Simulation Phantom and position Range: 110 MHz to 40 GHz. EN50383 under maintenance to take into account recent scientific results.

8 EN50383 content SAR measurement Limited to local SAR E-Field measurement Surface scanning Volume scanning E-Field simulation In free space

9 Putting on the market to determine compliance boundaries

10 Put Base Station into service Basic and product standards to demonstrate the compliance of the product when it is put into service EN50400 and EN50401 adopted by CENELEC in 2005 EN published in OJEC in 2006 Range 110 MHz to 40 GHz.

11 EN50400 Specify when it is put into service in its operational environment, the methods to assess the value of the Total Exposure Ratio or to establish whether the Total Exposure Ratio is less than or equal to one in relevent areas where the general public has access. Take into account -the environment - the other sources With a manageable method

12 In situ measurement This standard specifies the measurement methods that shall be used to determine in-situ human exposure assessment EN50492 under final discussion within NC, should be adopted in 2008 Range 100 khz to 300 GHz. Coherent with the EECCEPT-ECC and taking into account existing national measurement protocol

13 Measurement Protocol In-Situ Measurement Site analysis (clause 6) Source determination (clause 6.2) Case A : Global exposure assessment (broadband) Measurements (clause 9) Case B : Comprehensive exposure assessment (narrowband) Measurement system selection (clause 6-8) Measurement quantity determination (clause 7) Measurements (clause 9) Case determination (clause 6.3) Case A : Case B : power density S 10 mw/m² No power density S 10 mw/m² Extrapolation postprocessing (clause 10) (optional) (section) No Measurement uncertainty determination (clause 11) Ye s Measurement report preparation (clause 12)

14 50492 Specify basic requirements of measurement system Sensitivity, isotropy, frequency selectivity Specify the measurement protocol measurement method versus situation, averaging Extrapolate (if required) to the maximum traffic, post processing.. applicable to GSM, UMTS, WIFI.
