REN/ERM-TG17WG3-014-1

Elektromagnetna združljivost in zadeve v zvezi z radijskim spektrom (ERM) - Brezžični mikrofoni v frekvenčnem območju od 25 MHz do 3 GHz - 1. del: Tehnične karakteristike in merilne metode

Ta dokument zajema minimalne značilnosti, ki se štejejo za potrebne, da se najbolje izkoristi razpoložljiv frekvenčni spekter za brezžične mikrofone in pripomočke za slušno prizadete.
Ta dokument določa minimalne zahteve za zmogljivost in metode merjenja podpornih slušnih naprav, radijskih mikrofonov in nadzornih sistemov v ušesu. Ne vključuje nujno vseh značilnosti, ki jih potrebuje uporabnik, niti ne predstavlja nujno dosegljive optimalne zmogljivosti.
Ta dokument velja za opremo, ki deluje na radijskih frekvencah med 25 MHz in 3 GHz (kot prikazano v preglednici 1) z uporabo analogne, digitalne in hibridne (uporaba analogne in digitalne) modulacije.
Maksimalna priporočena moč za opremo, zajeto v tem dokumentu, je 250 mW za radijske mikrofone in 10 mW za ALD.
Izjema so javni slušni pripomočki, določeni v poročilu 004 CEPT [i.10], in pozneje ECC [i.12] in odločbe EK [i.11] na nekdanjem pasu ERMES (od 169,4 MHz do 169,8125 MHz), kjer je določen 500 mW.
Ta dokument prav tako zajema radijske mikrofone, ki se uporabljajo v pasu od 863 MHz do 865 MHz, z maksimalno močjo 10 mW.
Zahteve za elektromagnetno združljivost (EMC) so zajete v EN 301 489-9 [i.5]
Državni predpisi za:
1) maksimalno izhodno moč;
2) licenčni status
veljajo oziroma tisti, ki so podrobno opisani v zadnji različici:
• Odločba EK 2005/928/EK [i.12];
• Odločba ECC (05)02 [i.13];
• Odločba SRD EK [i.11]; ali
• CEPT/ERC/REC 70-03 [i.9], priloga 10 (glej http://www.erodocdb.dk/).
Če ni drugače navedeno v Odločbi SRD EK, Odločbi ECC ali državnih vmesnikih, so radijski mikrofoni lahko predmet posamezne licence.
Vrste opreme, ki jo ta dokument zajema, so:
• profesionalni sistemi brezžičnih mikrofonov (PWMS) [i.1];
• nadzorni sistemi v ušesu;
• potrošniški radijski mikrofoni;
• sistemi za vodenje; in
• podporne slušne naprave (pripomočki za invalide), sestavljene iz osebnih in javnih sistemov slušnih pripomočkov.
