Elektromagnetna združljivost in zadeve v zvezi z radijskim spektrom (ERM) - Naprave kratkega dosega (SRD) - Tehnične karakteristike za opremo SRD, ki uporablja ultra širokopasovno (UWB) tehnologijo - Objektna diskriminacija in karakterizacija motorno gnanih naprav, ki obratujejo v frekvenčnem pasu od 2,2 GHz do 8,5 GHz - 1. del: Tehnične karakteristike in preskusne metode
Pričujoči dokument določa zahteve za aplikacije objektne diskriminacije in karakterizacije (ODC) motorno gnanih naprav z uporabo tehnologije UWB, ki deluje v celotnem ali delu frekvenčnega pasu od 2,2 GHz do 8,5 GHz. Poleg tega določa zmanjšane emisije v pasovih od 0,96 GHz do 2,2 GHz in 8,5 GHz do 10,6 GHz. Pričujoči dokument velja za:
a) UWB opremo za objektno diskriminacijo in karakterizacijo za aplikacije slikanja in detekcijo objektov;
b) opremo, opremljeno z vgrajeno anteno;
c) dve glavni kategoriji:
1) kategorija A: zaščita uporabnika pri namiznih orodjih/miznih žagah (navidezno pritrjeni opremi za žaganje).
2) kategorija B: zaščita proti preboju pri vrtalnih napravah.
Pričujoči dokument ne velja za:
- UWBkomunikacijske naprave in
georadarske naprave ter
- naprave za radarsko slikanje skozi steno;
- naprave za gradbeni material;
kot določeno v Priporočilu ITU-R SM.1754 [i.1] in EN 302 435-1 [i.6]. Pričujoči dokument določa opremo, ki je narejena tako, da ne seva v odprti prostor. Načrtovan je, da deluje samo takrat, kadar je nameščen tako, da seva naravnost v:
a) prosti prostor (za opremo A kategorije) ali
b) absorptivni material, kot so stene in drugi gradbeni materiali, ki absorbirajo emisije kategorije B. Pričujoč dokument ne vključuje nujno vseh značilnostih, potrebnih za uporabnika, niti nujno ne predstavlja največje dosegljive zmogljivosti.

ETSI ETSI EN 302 498-1 V1.1.1 (2010-06) 8 1 Scope The present document specifies the requirements for Object Discrimination and Characterization Applications (ODC) for power tool devices using UWB technology operating in all or part of the frequency band from 2,2 GHz to 8,5 GHz. Additionally, it specifies reduced emissions in the ranges from 0,96 GHz to 2,2 GHz and 8,5 GHz to 10,6 GHz.
The present document applies to: a) UWB object discrimination and characterisation equipment for imaging and object detection applications; b) equipment fitted with an integral antenna; c) Two main categories: 1) Category A: user protection in bentchtop tools/table saws (quasi fixed sawing equipment). 2) Category B: breakthrough protection in drilling devices. The present document does not apply to: • UWB communication devices; and • Ground penetrating radar devices; and • through-wall radar imaging devices; • building material devices; as defined in ITU-R Recommendation SM.1754 [i.1] and EN 302 435-1 [i.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:
a) free space (for category A equipment); or
b) to the absorptive material such as walls and other building materials which absorb emissions for category B.
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 specific (identified by date of publication and/or edition number or version number) or non-specific. For specific references, only the cited version applies. For non-specific references, the latest version of the reference document (including any amendments) applies.

1 Scope
The present document specifies the requirements for Object Discrimination and Characterization Applications (ODC)
for power tool devices using UWB technology operating in all or part of the frequency band from 2,2 GHz to 8,5 GHz.
Additionally, it specifies reduced emissions in the ranges from 0,96 GHz to 2,2 GHz and 8,5 GHz to 10,6 GHz.
The present document applies to:
a) UWB object discrimination and characterisation equipment for imaging and object detection applications;
b) equipment fitted with an integral antenna;
c) Two main categories:
1) Category A: user protection in bentchtop tools/table saws (quasi fixed sawing equipment).
2) Category B: breakthrough protection in drilling devices.
The present document does not apply to:
• UWB communication devices; and
• Ground penetrating radar devices; and
• through-wall radar imaging devices;
• building material devices;
as defined in ITU-R Recommendation SM.1754 [i.1] and EN 302 435-1 [i.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:
a) free space (for category A equipment); or
b) to the absorptive material such as walls and other building materials which absorb emissions for category B.
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.

1) Category A: user protection in bentchtop tools/table saws (quasi fixed sawing equipment).
2) Category B: breakthrough protection in drilling devices.
The present document does not apply to:
• UWB communication devices; and
• Ground penetrating radar devices; and
• through-wall radar imaging devices;
• building material devices;
as defined in ITU-R Recommendation SM.1754 [i.1] and EN 302 435-1 [i.6].
The present document specifies the equipment which is designed to not radiate into the free space. It is designed to

1 Scope
The present document specifies the requirements for Object Discrimination and Characterization Applications (ODC)
for power tool devices using UWB technology operating in all or part of the frequency band from 2,2 GHz to 8,5 GHz.
Additionally, it specifies reduced emissions in the ranges from 0,96 GHz to 2,2 GHz and 8,5 GHz to 10,6 GHz.
The present document applies to:
a) UWB object discrimination and characterisation equipment for imaging and object detection applications;
b) equipment fitted with an integral antenna;
c) Two main categories:
1) Category A: user protection in bentchtop tools/table saws (quasi fixed sawing equipment).
2) Category B: breakthrough protection in drilling devices.
The present document does not apply to:
• UWB communication devices; and
• Ground penetrating radar devices; and
• through-wall radar imaging devices;
• building material devices;
as defined in ITU-R Recommendation SM.1754 [i.1] and EN 302 435-1 [i.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:
a) free space (for category A equipment); or
b) to the absorptive material such as walls and other building materials which absorb emissions for category B.
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.
