DIN EN 13757-5:2009-01

This standard defines the requirements for the protocols to use when performing relaying in wireless meter readout networks. This document is an extension to Part 4 of EN 13757 'Wireless meter readout (Radio meter reading for operation in the 868 MHz to 870 MHz SRD band)'. It supports the routing of mode R2, but the routing of mode S and T is not supported. The main use of this standard is to support routed wireless networks for the readout of meters. Note: Electricity meters are not covered by this standard, as the standardisation of remote readout of electricity meters is a task for IEC/CENELEC.
