SIST EN 50090-5-3:2016

Home and Building Electronic Systems (HBES) - Part 5-3: Media and media dependent layers - Radio Frequency for HBES Class 1

This European Standard defines the mandatory and optional requirements for the medium specific Physical and Data Link Layer of HBES Radio Frequency.
Data Link Layer interfaces and general definitions that are medium independent are given in EN 50090 4 1.
This European standard defines the requirements for HBES RF Ready and HBES RF Multi devices. HBES RF Ready is a single RF channel system. HBES RF Multi is an RF multichannel evolution of HBES RF Ready system with 2 additional RF channels for fast reaction time products and 2 RF channels for slow reaction time products.
HBES RF Multi, specified below provides the following features:
-   more reliability in Frame transmissions in presence of interferers.
-   more efficiency when more HBES RF products are installed at the same location.
-   mixing of permanent and non-permanent receiving products.
-   mixing of fast and slow reaction time devices.
-   Listen Before Talk.
Fast RF channels are mainly intended to be used with human controlled applications like for example lights, shutters… Slow RF channels are mainly intended to be used with non-permanent receivers for automatic applications like sensors (smoke, temperature, wind, etc.), heating control, etc.
Compatibility issues with products in compliance with the former HBES RF specification (HBES RF 1.1) and the new versions are considered in Clause 7 at the end of this document.

Elektrische Systemtechnik für Heim und Gebäude (ESHG) - Teil 5-3: Medien und medienabhängige Schichten - Signalübertragung über Funk für ESHG Klasse 1

Systèmes électroniques pour les foyers domestiques et les bâtiments (HBES) - Partie 5-3: Médias et couches dépendantes des médias - Radio Fréquence pour HBES Classe 1

La présente Norme européenne définit les exigences obligatoires et facultatives relatives à la couche physique et à la couche liaison de données, spécifiques au média, de la radiofréquence HBES.
Les interfaces de la couche liaison de données ainsi que les définitions générales, qui sont indépendantes du média, sont données dans l'EN 50090-4-1.
La présente Norme européenne définit les exigences relatives aux dispositifs HBES RF Ready et HBES RF Multi. Le système HBES RF Ready est un système RF monocanal. Le système HBES RF Multi est une évolution multicanal du système HBES RF Ready, avec deux canaux RF supplémentaires pour les produits offrant un temps de réaction réduit et deux canaux RF pour les produits offrant un temps de réaction étendu.
Le système HBES RF Multi spécifié ci-après présente les fonctionnalités suivantes:
-   plus grande fiabilité des transmissions de trames en présence de brouilleurs;
-   plus grande efficacité lorsqu'un grand nombre de produits HBES RF sont installés au même endroit;
-   association de récepteurs permanents et non permanents;
-   association de dispositifs à temps de réaction réduit et à temps de réaction étendu;
-   application du concept « écouter avant de parler » (LBT, Listen Before Talk).
Les canaux RF rapides sont principalement destinés aux applications commandées par l'homme, par exemple les éclairages, les volets… Les canaux RF lents sont principalement destinés aux récepteurs non permanents, pour des applications automatisées telles que les détecteurs (de fumée, de température, de vent, etc.), la commande du circuit de chauffage, etc.
Les problèmes de compatibilité entre les produits conformes à l'ancienne spécification HBES RF (HBES RF 1.1) et les nouvelles versions sont abordés dans l'Article 7, à la fin du présent document.

Stanovanjski in stavbni elektronski sistemi (HBES) - 5-3. del: Mediji in nivoji, odvisni od medijev - Radijska frekvenca za HBES razreda 1

Ta evropski standard opredeljuje obvezne in izbirne zahteve za fizično in podatkovno povezovalno plast, ki je odvisna od medija, radiofrekvenčnih sistemov HBES.
Vmesniki in splošne opredelitve podatkovne povezovalne plasti, ki so neodvisni od medija, so podani v standardu EN 50090 4 1.
Ta evropski standard opredeljuje zahteve za naprave HBES RF Ready in HBES RF Multi. HBES RF Ready je sistem z enim radiofrekvenčnim kanalom. HBES RF Multi je večkanalna različica sistema HBES RF Ready z dvema dodatnima radiofrekvenčnima kanaloma za izdelke s hitrim reakcijskim časom in dvema radiofrekvenčnima kanaloma za izdelke s počasnim reakcijskim časom.
Sistem HBES RF Multi ponuja naslednje:
– več zanesljivosti pri prenosih okvirja v prisotnosti motečih elementov,
– več učinkovitosti, ko je več izdelkov HBES RF nameščenih na isti lokaciji,
– možnost istočasne uporabe stalnih in nestalnih sprejemnih izdelkov,
– možnost istočasne uporabe naprav s hitrim in počasnim odzivnim časom.
– protokol Listen Before Talk.
Hitri radiofrekvenčni kanali so namenjeni uporabi z aplikacijami, ki jih upravlja človek, kot na primer luči, roloji itd. Počasni radiofrekvenčni kanali so predvsem namenjeni uporabi z nestalnimi sprejemniki za avtomatske aplikacije, kot so senzorji (dimni, temperaturni, vetrovni itd.), nadzor ogrevanja itd.
Težave z združljivostjo z izdelki, ki so skladni s prejšnjo specifikacijo HBES RF (HBES RF 1.1) in novimi različicami, so zajeti v točki 7 na koncu tega dokumenta.

5.1.3 Medium access RF Ready
5.1.3.1 Definition and use
Medium access control shall serve for prevention of collisions on the RF medium. For two reasons
medium access cannot be completely controlled on RF.
1) Unidirectional senders access the medium at non-predictable times.
2) Non HBES RF devices access the medium at non-predictable times.
Bidirectional devices shall be able to sense whether the medium is free before they transmit. The inter-
Frame time shall be the time interval during which a bidirectional device shall wait for a free medium
(regardless of whether it is addressed by a preceding Frame or not). If no preamble is detected during
this interFrame time the device may start sending.
If a Frame is received while the Physical Layer gets a request to send, the interFrame time shall start
after the Frame reception is completed, this is after the last CRC is received. The same shall apply for
sending: if the Physical Layer gets a send request while it is sending, the interFrame time shall start when
the last CRC is transmitted.
NOTE RF supports no collision avoidance; therefore the transmission priorities are not coded in the Frame.

The assumed typical ‘blind time’ for devices is 1 ms.
The step for the random time shall be 1 ms.
5.2 Physical Layer for HBES RF Multi
5.2.1 General requirements (HBES RF Multi)
The RF channels used in the HBES RF Multi shall be composed of the following 3 + 2 RF channels.
Table 5 – RF channels of the HBES RF Multi Physical Layer
signalling speed preamble length
RF channel name Abbreviation encoding
kbps ms
Primary fast RF channel F1 16,384 Manchester 15
Second fast RF channel F2 16,384 Manchester 15
Third fast RF channel F3 16,384 Manchester 15
Primary slow RF channel S1 8,192 Manchester 500
Second slow RF channel S2 8,192 Manchester 500

The RF channels shall be divided in two categories.
1) The first category shall contain RF channels for “fast” RF Telegrams. The fast Telegrams shall
be composed of a short 15 ms wake-up at 16,384 kbps signalling speed.
2) The second category contains RF channels for “slow” RF Telegrams. The slow Telegrams are
composed of a long 500 ms wake-up at 8,192 kbps signalling speed.
The two categories of RF channels define explicitly two application domains.
EXAMPLE 1 Non-permanent receivers: smoke sensors, heating control.
EXAMPLE 2 Permanent receivers: all devices concerning human interaction
The first three Fast RF channels are primarily used in application for fast permanent and non-permanent
receivers and the last two RF channels are primarily used for slow non-permanent Rx devices. The
receiver reception capability determines the preamble length.
Devices from both categories can coexist independently without link or with links done by specific mains
powered products receiving all the 5 RF channels.
Fast Telegrams are Telegrams transmitted on any of the Fast RF channels; slow Telegrams are
Telegrams transmitted on a Slow RF channel.

---------------------- Page: 11 ----------------------

SIST EN 50090-5-3:2016
EN 50090-5-3:2016 (E)
Typically NPRM devices using slow Telegrams can only receive RF Telegrams with long wake-up. This
enables the NPRM devices to stay in low power mode most of the time and to become periodically active
for the reception of a long preamble. It is suggested that battery powered devices use mainly the RF
channels S1 and S2 with the lower data rate.
PRM devices supporting the Fast RF channels shall be in permanent scanning and receiving mode.
NPRM devices supporting the Fast RF channels shall scan each RF channel every 15 ms (1 ms for
hopping, 1 ms for scanning one RF channel). If a preamble is detected, it shall listen to the Frame, if not it
shall jump to next RF channel.
A receiver on only one RF channel without scanning any other is not permitted.
In the first three Fast RF channels, the first RF channel is the one used by RF HBES Ready devices and
the two other Fast RF channels are escape RF channels used in case of a busy RF channel.
In the two Slow RF channels, the first one is S1 for slow products and the other Slow RF channels is an
escape RF channel used in case of a busy RF channel.
Devices will mainly use F1, F2, F3 or S1, S2: 5 RF channels will only in very seldomly be supported in
applications.
