EN 50090-5-3:2016 (E)BS EN 50090-5-3:20161 Scope This European Standard defines the mandatory and optional requirements for the medi
25、um 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 channe
26、l 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 i
27、n 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 co
28、ntrolled 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 R
29、F specification (HBES RF 1.1) and the new versions are considered in Clause 7 at the end of this document. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

For two reasons medium access cannot be completely controlled on RF. 1) Unidirectional senders access th
46、e 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 fre
47、e 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 comp
48、leted, 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 cod
49、ed in the Frame.
