Electromagnetic compatibility and Radio spectrum Matters (ERM);Wireless microphones in the 25 MHz to 3 GHz frequency range; Part 1: Technical characteristics and methods of measurement
The present document covers the minimum characteristics considered necessary in order to make the best use of the
available frequency spectrum for wireless microphones and Aids for the hearing impaired.
The present document specifies the minimum performance requirements and the methods of measurement of Assistive
Listening Devices, radio microphones and in-ear monitoring systems. It does not necessarily include all the
characteristics that may be required by a user, nor does it necessarily represent the optimum performance achievable.
The present document applies to equipment operating on radio frequencies between 25 MHz and 3 GHz (as shown in
table 1) using analogue, digital and hybrid (using both analogue and digital) modulation.
The maximum power recommended for equipment covered by the present document is 250 mW for radio microphones
and 10 mW for ALDs.
An exception to this are the Public Hearing Aids defined in the CEPT Report 004 [i.9] and subsequent ECC [i.11] and
EC Decisions [i.10] on the ex ERMES band (169,4 MHz to 169,8125 MHz) where 500 mW is defined.
The present document also covers radio microphones used in the 863 MHz to 865 MHz band, with a maximum power
of 10 mW.
Electromagnetic Compatibility (EMC) requirements are covered by ETSI EN 301 489-9 [i.4].
National regulations on:
1) maximum power output;
2) licensing status;
will apply or those detailed in the latest version of:
• EC Decision 2005/928/EC [i.11];
• ECC/DEC/(05)02 [i.12];
• the EC SRD Decision [i.10]; or
• CEPT/ERC/REC 70-03 [i.8], annex 10 (see http://www.erodocdb.dk/).
Unless otherwise stated in the EC SRD Decision, ECC Decision or National Interfaces, Radio Microphones can be
subject to individual licence.
The types of equipment covered by the present document are as follows:
• in ear monitoring systems;
• consumer radio microphones;
• tour guide systems; and
• Assistive Listening Devices (Aids for the handicapped) comprising personal and public hearing aid systems.
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.
