Foreword This Techni
20、cal 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
21、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
22、 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 t
23、o 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
24、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 tho
25、se 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 lab
26、oratory 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. ETSI ETSI TR 102 626 V1.1.1 (2009-08) 61 Scope The pre
27、sent document defines the requirements for radio frequency usage by Citizens Band (CB) Radio which may require a change in the present regulatory framework regarding output power and modulation. The present document includes necessary information to support the co-operation between ETSI and the Elec
28、tronic Communications Committee (ECC) of the European Conference of Post and Telecommunications Administrations (CEPT), including: market information; technical information; expected sharing and compatibility issues; results of compatibility tests. 2 References References are either specific (identi

43、ons (as described in EN 300 433 i.4). Whilst these devices are not at present considered as Short Range Devices (SRDs) by CEPT, ERC/DEC(98)11 i.2 states that “The CEPT PR 27 application is intended for short range radio communications with transmission and reception taking place on the same channel
44、(single frequency, simplex traffic). The radio equipment is designed to be used without the need to have any technical qualifications.“ Therefore, CB radio usage has many characteristics of SRDs contained in CEPT/ERC Recommendation 70-03 i.7 in that it is meant for non technical users and is mobile
45、throughout Europe. It is proposed that ECC and EC may consider harmonizing the frequencies used by CB radio as far as possible, taking into account the results from spectrum engineering studies as proposed by the present document. ECC is requested to conclude their investigations before end of 2009.
46、 9.2 Expected ETSI actions EN 300 135 i.3 and EN 300 433 i.4 are already published as Harmonized European Standards along with EN 301 489-1 i.5 and EN 301 489-13 i.6. It is planned to revise EN 300 433 i.4 to include new power limits and consider the methods of measurement associated with the propos
47、ed power increase. ETSI ETSI TR 102 626 V1.1.1 (2009-08) 14A revision of TR 101 837 i.11 to include the results of measurements as covered by annex A may also be envisaged.

48、from CB radio has traditionally been to Television Broadcast receivers and a possible interference with the working of heart pace makers (WGRR/PT11 (98)28 i.10 annex 11). These issues have been addressed by: Compatibility testing carried out by the Test Laboratory of the German Federal Network Agenc
49、y, results are provided in clause A.3. The conclusion states: No blocking or other kind of picture or sound degradation was visible below a CB radio interference level of 25 dBm at the TV receiver input (valid for both, SSB and AM modulation). Taking into account the minimum isolation provided by free space propagation loss, 4 Watt AM/FM CB radiated signals as well as SSB CB radiated signals with 12 Watt PEP appear unlikely to create visible interference to DVB-T reception.
