Wireless M-Bus Repeater (230 VAC, IP67)
Measure to manage
The mains powered FX-WMBUS-R4-M-LR is a wireless MBUS repeater mounted with AC/DC adapter in combined enclosure. The device is a plug-and-play and highly configurable repeater for extending the range between meters and a collector/gateway. The enclosure is chosen to make the repeater as discrete as possible.
Once a minute a packet is sent from the repeater and contains information about the repeater, such as number of routed packets, software version, and current battery level. The packet is also used for time synchronizing between repeaters in a multihop system. Furthermore, this packet can be used as an indication that the device is up and running and the load of the repeater.
The repeater makes use of two high performance internal antennas. The internal antennas are mounted at 90 degrees from each other, thus taking advantage of both horizontal and vertical polarizations for maximum range. This diversity is important, especially for indoor operation since meters and gateway can be mounted either to the sides or above/below the repeater. If meters have different polarization (antenna alignment) a loss of up to 30 dBm can be observed. Having two antennas at an angle also minimizes multipath problems.
