The signal repeater Wireless M-Bus-RFM RPT3, is a device that allows to repeat, extending its coverage, the radio signal transmitted by the radio modules installed on water meters, heat meters and heat cost allocators, in accordance with the WMBUS standard.

The device can be set with a daily activities window, inside which it performs the repetition of WMBUS telegrams in accordance with the requirements of the EN13757 standard.

It then repeats the signals sent by the measuring devices excluding those already repeated and sent from other repeating devices (simple repeater with single-hop logic).

The same device can be set notwithstanding the standard, to enable the realization of up to 3 levels repeating chains.
