L'IEC 60728-1-1:2014 s'applique aux câblages RF destinés aux réseaux domestiques bidirectionnels utilisant des cordons à fil ou des liaisons sans fil à l'intérieur d'une pièce et essentiellement destinés aux signaux de télévision et de radiodiffusion sonore utilisés approximativement entre 5 MHz et 3 000 MHz. La bande de fréquences est étendue à 6 000 MHz pour des techniques de distribution où les cordons à fil sont remplacés par une communication bidirectionnelle sans fil. Cette deuxième édition annule et remplace la première édition parue en 2010, dont elle constitue une révision technique. Elle inclut les modifications suivante: mise à jour des exigences de qualité de l'Article 5 afin d'inclure les exigences pour les signaux DVB-T2.

Standard določa zahteve in opisuje izvedbene smernice RF-okablenja za dvosmerna domača omrežja. Ta standard se uporablja za katero koli domače omrežje, ki distribuira signale, ki jih posredujejo kabelska omrežja CATV/MATV/SMATV (vključno s posamičnimi sistemi za sprejem) s koaksialnim kabelskim izhodom. Ta standard se uporablja tudi za domača omrežja, pri katerih del razdelilnega omrežja uporablja brezžične povezave, na primer namesto sprejemnega kabla. Ta del standarda IEC 60728 se torej uporablja za radiofrekvenčne kable za dvosmerna domača omrežja z žičnimi kabli ali brezžičnimi povezavami znotraj sobe ter je namenjen predvsem za televizijske in zvokovne signale s frekvenco med približno 5 MHz in 3000 MHz. Frekvenčni razpon se poveča na 6000 MHz pri distribucijskih tehnikah, ki nadomeščajo žične kable z brezžično dvosmerno komunikacijo znotraj sobe (ali manjšega števila sosednjih sob), ki uporablja pas med 5 GHz in 6 GHz.

Overview

CWA 45546-1:2004 (IEC 60728-1-1:2014) defines requirements and implementation guidelines for RF cabling in two‑way home networks. It applies to home networks that distribute signals from CATV / MATV / SMATV systems (or individual receivers) with a coaxial cable output, and to hybrid networks where part of the distribution uses wireless links inside a room. The standard covers RF signals primarily between about 5 MHz and 3 000 MHz, with an extended range up to 6 000 MHz for wireless two‑way in‑room distribution.

Key topics and technical requirements

• Scope & applicability: Home networks distributing television, sound and interactive services from cable or satellite distribution systems, including wired and in‑room wireless links.
• Measurement methods: Procedures for measuring RF performance of the home network and system outlets.
• Performance requirements (Clause 5): Impedance, terminal input and system outlet signal levels, isolation between outlets, forward/return path isolation, long‑term frequency stability, and carrier level differences from the Home Network Interface (HNI) to outlets. Updated to include DVB‑T2 performance.
• Noise and interference control: Limits and guidance on random noise, cross‑modulation, intermodulation and other interference into downstream channels.
• Design and implementation guidance: Network planning, example topologies, coaxial and balanced cable considerations, return path design, and calculation examples for installers and designers.
• Wireless coexistence: Use of IEEE 802.11 (WLAN) and other wireless links in the 2–6 GHz range; characteristics of WLAN signals and their interaction with coaxial distribution.
• Terminology and references: Definitions, symbols and normative references to related IEC, EN, ETSI and IEEE documents.

Practical applications

• Designing and installing reliable in‑home RF distribution for multiroom TV, IPTV and audio systems.
• Specifying and testing coaxial cabling, system outlets (SO), terminal inputs (TI) and Home Network Interfaces (HNI).
• Ensuring interoperability between wired coax networks and in‑room wireless two‑way links (e.g., replacement of receiver cords).
• Minimizing RF interference and ensuring compliance with operator/service performance expectations (including DVB‑T2 services).

Who should use this standard

• RF/network designers and system integrators
• Cable and satellite service providers, MATV/SMATV system designers
• Cabling installers, electrical contractors and test engineers
• Equipment manufacturers and product specifiers
• Building designers and facility managers specifying in‑home distribution

Related standards

• EN/IEC 60728‑1:2014 (system performance of forward paths)
• IEC 60728‑1‑2, IEC 60728‑3 (active equipment)
• IEC 60966 series (RF/coaxial assemblies)
• IEEE 802.11 (WLAN standards), ETSI DVB standards (DVB‑T2, DVB‑C, DVB‑S2)

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

INTRODUCTION
Standards and deliverables of IEC 60728 series deal with cable networks including equipment
and associated methods of measurement for headend reception, processing and distribution
of television and sound signals and for processing, interfacing and transmitting all kinds of
data signals for interactive services using all applicable transmission media. These signals
are typically transmitted in networks by frequency-multiplexing techniques.
This includes for instance
• regional and local broadband cable networks,
• extended satellite and terrestrial television distribution systems,
• individual satellite and terrestrial television receiving systems,
and all kinds of equipment, systems and installations used in such cable networks, distribution
and receiving systems.
The extent of this standardization work is from the antennas and/or special signal source
inputs to the headend or other interface points to the network up to the terminal input of the
customer premises equipment.
The standardization work will consider coexistence with users of the RF spectrum in wired
and wireless transmission systems.
The standardization of any user terminals (i.e. tuners, receivers, decoders, multimedia
terminals, etc.) as well as of any coaxial, balanced and optical cables and accessories thereof
is excluded.
The reception of television signals inside a building requires an outdoor antenna and a
distribution network to convey the signal to the TV receivers.
This part of the IEC 60728 deals with the requirements and implementation guidelines for a
home network that can be realised with different techniques. The following types of home
networks (HN) are possible:
• passive coaxial home network;
• active coaxial home network;
• different home network types.
Figure 1 shows typical situations that are possible when considering RF home networks.
The RF home network can be realised using coaxial cables, balanced cables, optical cables
or radio links.
Clause 5 defines the performance limits measured at system outlet or terminal input for an
unimpaired (ideal) test signal applied at the HNI. Under normal operating conditions for any
analogue channel and meeting these limits, the cumulative effect of the impairment of any
single parameter at the HNI and that, due to the home network, will produce picture and
sound signals not worse than grade four on the five-grade impairment scale contained in
ITU-R BT.500. These requirements are given in IEC 60728-1-2. For digitally modulated
signals the quality requirement is a QEF (Quasi Error Free) reception.
This standard describes the physical layer connection for home networks. Description of
protocols required for Layer 2 and higher layers is out of the scope of this standard. Logical
connections between devices within the home network are therefore not always guaranteed.

CABLE NETWORKS FOR TELEVISION SIGNALS,
SOUND SIGNALS AND INTERACTIVE SERVICES –

Part 1-1: RF cabling for two way home networks

1 Scope
This part of IEC 60728 provides the requirements and describes the implementation
guidelines of RF cabling for two-way home networks. This standard is applicable to any home
network that distributes signals provided by CATV/MATV/SMATV cable networks (including
individual receiving systems) having a coaxial cable output. This standard also applies to
home networks where some part of the distribution network uses wireless links, for example
instead of the receiver cord.
This part of IEC 60728 is therefore applicable to RF cabling for two-way home networks with
wired cords or wireless links inside a room and primarily intended for television and sound
signals operating between about 5 MHz and 3 000 MHz. The frequency range is extended to
6 000 MHz for distribution techniques that replace wired cords with a wireless two-way
communication inside a room (or a small number of adjacent rooms) that uses the 5 GHz to
6 GHz band.
