The MBWGPRS is a wireless M-Bus T1, T2 and C1 transceiver (EN13757-4 / OMS) with data logger, UMTS / GPRS modem and lithium battery power supply. The integrated USB interface is used for configuration. The MBWGPRS is programmed for a certain radio reading interval (e.g. once per hour or every 6 hours) where it switches on its internal T1 receiver and stores all received radio telegrams to the internal data logger memory. Equally, it is programmed to connect itself to the Internet using a UMTS / GPRS connection and upload the received radio data to an FTP server (e.g. four times per month). Since the MBWGPRS is working without external power supply and since it only needs a mobile network (UMTS / GPRS) for connections to the Internet it may be operated at nearly every installation location.
