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 karakteristike za čim učinkovitejšo uporabo frekvenčnega spektra, ki je na voljo za brezžične mikrofone in slušne aparate. Ta dokument določa minimalne zahtevane lastnosti in merilne metode podpornih slušnih pripomočkov, radijskih mikrofonov in slušno-monitornih sistemov. Ne vključuje nujno vseh karakteristik, ki bi jih lahko potreboval uporabnik, in ne predstavlja nujno najboljšega mogočega delovanja.
Ta dokument se uporablja za opremo, ki deluje na radijskih frekvencah med 25 MHz in 3 GHz (kot je prikazano v tabeli 1) z uporabo analogne in digitalne modulacije ter hibridne modulacije, ki uporablja tako analogno kot digitalno modulacijo. Priporočena največja moč za opremo, ki je zajeta v tem dokumentu, je 250 mW za radijske mikrofone in 10 mW za podporne slušne pripomočke.
Izjema so javni slušni aparati, opredeljeni v poročilu CEPT 004 [i.9] ter odločbah ECC [i.11] in ES [i.10] glede nekdanjega pasu ERMES (169,4 MHz do 169,8125 MHz), kjer je opredeljena moč 500 mW. Ta dokument zajema tudi radijske mikrofone, ki s uporabljajo v pasu 863 MHz do 865 MHz z največjo močjo 10 mW.
Zahteve za elektromagnetno združljivost (EMC) zajema dokument ETSI EN 301 489-9 [i.4].
Uporabljali se bodo nacionalni predpisi, ki zajemajo:
1) največjo izhodno moč;
2) licenčni status;
ali tisti predpisi, ki so vključeni v najnovejše različice:
• odločbe ES 2005/928/ES [i.11];
• odločbe ECC/DEC/(05)02 [i.12];
• odločbe ES SRD [i.10] ali
• dodatka 10 k priporočilu CEPT/ERC/REC 70-03 [i.8] (glej http://www.erodocdb.dk/).
Za radijske mikrofone so morda potrebne posebne licence, razen če je določeno drugače v odločbi ES SRD, odločbi ECC ali nacionalnih vmesnikih.
Ta dokument zajema naslednje vrste opreme:
• slušno-monitorne sisteme;
• potrošniške radijske mikrofone;
• sisteme za vodene oglede; in
• podporne slušne pripomočke (pripomočki za invalide), ki vključujejo osebne in javne slušne sisteme.
