If you are using a building automation system (BAS) protocol operating on RF media at 19,200 b/s in the 868 MHz band, which protocol are you using?

EIB RF (European Installation Bus Radio Frequency) is standardized to use the 868 MHz license-free ISM band, which is the designated short-range device band in Europe, at a data rate of 19,200 b/s. These two parameters together - 868 MHz and 19,200 b/s - uniquely identify the EIB RF variant within the KNX/EIB protocol family. EIB is part of the broader KNX standard and is used for integrated building automation control including lighting, HVAC, and security applications.

LonTalk operates at 78 kbps over twisted-pair or power-line media within LonWorks networks and is not defined for RF operation in the 868 MHz band at 19,200 b/s.

MODBUS is a master-slave serial communication protocol originally designed for wired RS-232 and RS-485 connections and has no native specification for 868 MHz RF operation.

LonMark is an interoperability certification and testing organization for LonWorks-based devices, not a communication protocol specification.

Modicon is a brand name for Schneider Electric's line of programmable logic controllers and is not a communications protocol.
