Over deze norm
This European Standard applies to electrical equipment using signals in the 2 MHz - 4 MHz frequency range to transmit information on low voltage electrical systems/networks within installations in home. The purpose of this European Standard is to describe a mechanism to limit mutual interferences between equipment operating in the 2 MHz - 4 MHz frequency band and to specify the way systems should share the same band. It does not specify the signal modulation methods nor the coding methods or functional features (except those preventing mutual interference in the same band). Any new PLT product should be designed in respect with this standard which means that peak voltages of all transmitted signal within LRWBS will not exceed the maximum requirements of the normative EMC standards for this band. Applications complying with this coexistence standard may offer low rate (lower than 1 Mb/s) services in home. This European Standard: - covers typical applications such as energy efficiency, real-time displays of metering information, general command and control, home automation; - excludes high rate communication (higher than 1 Mb/s) applications such as Video or Internet networking.
