1. Overview
The Lobaro wireless M-Bus (wMBUS) to LoRaWAN Bridge is a cost-eective & energy-
ecient device that receives, caches and transparently forwards wireless M-Bus metering
data from up to 500 consumption meters via any LoRaWAN network onto the Internet.
Many gas, water, electricity and heat meters can be read wirelessly today using the common
short range Wireless M-Bus standard. Because such wMBUS enabled meters use the classical
energy saving FSK radio modulation, the wireless range is often limited to less than 50m
and therefore requires the use of additional longer-range radio technologies to forward the
metering data onto the Internet. The advanced LoRa radio modulation used inside the Lobaro
wMBUS to LoRaWAN Bridge is such a key technology.

LoRaWAN based LPWANs (Low Power wide area networks) allow connections to the Inter-
net from small battery powered devices with wireless ranges of up to 5 kilometers between
the transmitter and receiving gateway antenna - without the usual cellular network costs in
classical M2M or smart metering solutions. Also - unlike with cellular networks - it's possible
to setup own gateways if needed. This often results in much lower operational costs with the
Lobaro wMBUS bridge compared to conventional remote meter reading via LTE networks.
The metering data will not be decrypted by the LoRaWAN Bridge, instead an unchanged
1:1 forwarding takes place via one or more LoRaWAN packets (depending on the wMBUS
telegram byte size). Thus the end-to-end encryption of sensitive wireless MBUS consumption
data is preserved.
Initial conguration, rmware updates & status readouts are done user-friendly via USB on the
PC with the Lobaro Tool (Windows, Linux, Mac). An additional possibility of conguration
