IEC 60728-101-1:2023 provides the requirements and describes the implementation guidelines of RF cabling for two-way home networks; it 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. It is also applicable to home networks where some part of the distribution network uses wireless links, for example in place 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 3 300 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. In a building divided into apartment blocks, the distribution of the signals inside the home starts from the home network interface (HNI) up to the system outlet or terminal input. The requirements at the system outlet are given in IEC 60728-101:2016, Clause 5 and the requirements at the HNI are given in IEC 60728-101:2016, Clause 7. In Clause 5 of this document, additional requirements are given. This document deals with various possibilities to distribute signals in a home network, using coaxial cables, balanced pair cables, fibre optic cables (glass or plastic) and also wireless links inside a room (or a small number of adjacent rooms) to replace wired cords. This document gives references to basic methods of measurement of the operational characteristics of the home cable network in order to assess its performance. All requirements refer to the performance limits, which are obtained between the input(s) at the home network interface (HNI) and the output at any system outlet when terminated in a resistance equal to the nominal load impedance of the system, unless otherwise specified. Where system outlets are not used, the above applies to the terminal input. The present document also provides limits for the accumulation of degradations if the home network is subdivided into a number of parts, using different transmission media (e.g. coaxial cabling, balanced cabling, optical cabling, wireless 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 digital 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 produces signals not worse than the requirements given in IEC 60728-101-2. For digitally modulated signals, the quality requirement is a QEF (quasi error-free) reception. This document 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 document. Logical connections between devices within the home network are therefore not always guaranteed. This International Standard is to be used in conjunction with IEC 60728-101:2016. LIEC 60728-101-1:2023 formule les exigences et presente les lignes directrices de mise en ouvre dun cablage RF pour reseaux domestiques bidirectionnels. Elle sapplique a tous les reseaux domestiques qui distribuent les signaux transmis par les reseaux de distribution par cable CATV/MATV/SMATV (y compris les systemes individuels de reception) qui disposent dune sortie a cable coaxial. Elle sapplique egalement aux reseaux domestiques dans lesquels une partie du reseau de distribution utilise des liaisons sans fil (en lieu et place dun cordon de recepteur, par exemple). La presente partie de lIEC 60728 sapplique donc au cablage RF pour reseaux domestiques bidirectionnels avec cordons cables ou liaisons sans fil a linterieur dune piece, et concerne principalement les signaux de television et les signaux de radiodiffusion sonore compris entre 5 MHz et 3 300 MHz environ. La plage de frequences est etendue a 6 000 MHz pour les techniques de distribution qui remplacent les cordons cables par une communication bidirectionnelle sans fil a linterieur dune piece (ou dun nombre restreint de pieces adjacentes) qui utilise la bande comprise entre 5 GHz et 6 GHz. La distribution des signaux a linterieur dun batiment divise en blocs dappartements setend de linterface du reseau domestique (HNI) a la prise dabonne ou a lentree de terminal. Les exigences au niveau de la prise dabonne sont donnees a lArticle 5 de lIEC 60728-101:2016. Les exigences au niveau de linterface du reseau domestique sont donnees a lArticle 7 de lIEC 60728-101:2016. LArticle 5 du present document fournit des exigences supplementaires. Le present document traite des differentes possibilites de distribution des signaux dans un reseau domestique, a laide de cables coaxiaux, de cables a paires symetriques, de cables a fibres optiques (verre ou plastique) ainsi que de liaisons sans fil a linterieur dune piece (ou dun nombre restreint de pieces adjacentes) pour remplacer les cordons cables. Le present document fait reference a des methodes de mesure de base des caracteristiques operationnelles du reseau domestique de distribution par cable afin devaluer ses performances. Toutes les exigences font reference aux limites de performances qui sont obtenues entre lentree ou les entrees de linterface du reseau domestique (HNI) et la sortie de toute prise dabonne lorsquelle est equipee dune resistance de terminaison egale a limpedance de charge nominale du systeme, sauf specification contraire. Si les prises dabonne ne sont pas utilisees, les elements ci-dessus sappliquent a lentree de terminal. Le present document fournit egalement des limites concernant laccumulation des degradations si le reseau domestique est divise en plusieurs parties qui utilisent differents s
