Introduction As written in the scope the signal characteristics are defined across the operating frequency and in accordance with network equipment built to European standards. Clause 4 gives an overview of the cable network system architecture characteristics to suppor

20、t delivery of a wide range of digital entertainment and informational programming via the use of a hybrid fibre/coaxial network. It provides details of the frequency allocation and usage for digital television signals carried on the cable plant using channelization though different modulation. This

21、clause presents also characteristcis of the various signals delivered to the non-radio end user equipment for fixed broadcasting and broadband electronic communication services, in particular those services delivered by cable operators in Europe, analogue television, digital television, telephony an

22、d high speed data (internet). Clause 5 gives details of the signal characteristics of European CATV systems and their protection criteria in terms of the minimum and maximum signal levels and the signal to noise level thresholds before the desired signal is disturbed to a level that impacts its rece

23、ption by the non-radio end user equipment for fixed broadcasting and broadband electronic communication services. Three instances of harmful interference from new radio services (NRS) operating in the frequency bands occupied currently by cable networks is considered , the first is between the NRS a

24、nd coaxial part of the network (both in-home and external), the second is defined between the NRS system and a remote cable headend receiver and the third type of interference is defined from the NRS system on the non-radio end user equipment itself (e.g. cable modem, settopbox, digital cable receiv

25、ers, etc.). ETSI ETSI TS 102 866 V1.1.1 (2014-07)5Clause 6 gives calculation methods in terms of the limits of unwanted signals and their relevant characteristcis that can influence the reception of the delivered signal by the cable network to non-radio end user equipment for fixed broadcasting and

26、broadband electronic communication services. Equations are derived based on noise margins and maximum interference levels for calculations of acceptable limits across different operating frequency ranges and modulations. The limits derived are based on the characteristcis of cable distribution netwo

27、rks built according to European standards and industry best practices. Calculations of maximum EIRP limits for no degradable service (dBm) i.e. to mitigate impact to the non-radio end user equipment for fixed broadcasting and broadband electronic communication services are presented in relation to t

28、he distance between the radio transmitter and cable system. The graphs given present typical use cases with modulation and signal maximum and minimum levels as operated by European cable networks. Clause 7 contains references to experiments that are representative as realistic situations with respec

29、t to the calculated results. Clause 8 gives a summary of the potential impact from new radio services operating within the frequency bands currently used by cable networks to non-radio end user equipment for fixed broadcasting and broadband electronic communication services. ETSI ETSI TS 102 866 V1.

30、1.1 (2014-07)61 Scope The present document defines the transmitted signal characteristcis delivered across a HFC cable network to the customer network interfaces distributed within the home network received and processed by the consumer end terminals for reception of multimedia services. The signal

31、characteristics are defined across the operating frequency and in accordance with network equipment built to European standards. The present document provides valuable input to engineers and developers containing the technical basis to take into account when developing harmonized technical condition

32、s for new radio services operating in the same frequency range as currently occupied by cable distribution networks. It presents the technical basis for coexistence between these new radio services and existing non-radio end-user equipment for fixed broadcasting and broadband electronic communicatio

33、n services, specifically those services delivered by European cable based systems (PAL/SECAM, DVB-C, Euro-DOCSIS). The impact to non-radio end user equipment for fixed broadcast and broadband electronic communication services is given in terms of the operational characteristics of the wanted signals

34、 and tolerable limits of the unwanted signals as a factor of the distance between them before the unwanted interfering signal will disrupt the end users equipment for fixed broadcasting and broadband electronic communication services (e.g. digital and analogue television, internet high speed data an

35、d telephony services). 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
