Intellectual Property Rights

IPRs essential or potentially essential to the present document may have been declared to ETSI. The information

pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found

in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in

respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web

server (http://webapp.etsi.org/IPR/home.asp

Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee

can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web

server) which are, or may be, or may become, essential to the present document.

Foreword

This Technical Report (TR) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio

spectrum Matters (ERM).

Introduction

The present document has been developed to support the co-operation between ETSI and the Electronic

Communications Committee (ECC) of the European Conference of Post and Telecommunications Administrations

(CEPT).

Technical parameters for terrestrial television have changed dramatically since the original investigation of

compatibility between Citizens' Band Radio (CB) and domestic receivers resulting in ERC Recommendation

T/R 20-09 [i.1] (Chester 1990) and the ERC/DEC(98)11 [i.2].

The present document seeks to explore those changes along with the change in use patterns of CB users.

Following the Chester 1997 Multilateral Coordination Agreement television is now well on the way to becoming fully

digital throughout Europe in the UHF frequency range 470 MHz to 862 MHz, whilst the use patterns of CB is now

increasingly mobile, thus the original interference problem of domestic use of CB at 27 MHz and terrestrial television at

45 MHz to 70 MHz are a subject of the past.

Increasingly stringent EMC requirement (within EN 60601 [i.9]) for pacemakers and other medical implants referred to

in document WGRR/PT11 (98)28 annex 11 [i.10] are no longer likely to receive sufficient EMF from CB radio devices

to interfere in any way with their function.

At present National regulations within Europe are not fully harmonized which is confusing for users especially those

such as long distance truck drivers crossing a number of National borders in a day and needing to change settings on

their transmitters. CB may be considered as one of the first implementations of the e-safety and Intelligent Transport

System agendas.

The present document seeks to examine via laboratory tests, practical tests and calculation the compatibility issues

which are likely to occur with modern equipment and considers the present regulation with a view to achieving full

harmonization of both technical parameters and regulation.
