Foreword This European Standard
24、(Telecommunications series) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). Equipment covered by the present document operates in accordance with ECC Decision ECC/DEC(07)01 on Building Material Analysis (BMA) devices. For non EU countries
25、 the present document may be used for regulatory (Type Approval) purposes. The present document is part 1 of a multi-part deliverable covering Ultra WideBand (UWB) Building Material Analysis (BMA) and Classification equipment applications operating in the frequency band from 2,2 GHz to 8 GHz, as ide
26、ntified below: Part 1: “Technical characteristics and test methods“; Part 2: “Harmonized EN covering the essential requirements of article 3.2 of the R b) equipment fitted with an integral antenna; c) handheld devices. The present document does not apply to: UWB communication devices; and Ground pen
27、etrating radar devices; and through-wall radar imaging devices; as defined in ITU-R Recommendation SM.1754 6. The present document specifies the equipment which is designed to not radiate into the free space. It is designed to function only when positioned such that it radiates directly into the abs
28、orptive material such as walls and other building materials which absorb emissions. The present document does not necessarily include all the characteristics which may be required by a user, nor does it necessarily represent the optimum performance achievable. 2 References References are either spec
