Where a geotechnical or structural monitoring solution is required to cover a large area, such as a mine or a city, we would usually recommend our GeoWAN communication platform.
GeoWAN uses a lower frequency radio band than FlatMesh. It is based on the industry-standard LoRaWAN protocol and is capable of long-range transmission with sensors able to communicate with a gateway at a distance as great as 15 km.
Monitoring systems using GeoWAN have the power to transmit through physical obstructions, enabling, for example, integration of sensors in boreholes or on buildings above a tunnel with movement sensors measuring deformation inside the tunnel.
From the gateway the options for getting the data to the outside world are restricted only by the available infrastructure. The simplest option in most cases is to use the gateway’s integrated cellular (2G/3G/4G) modem; alternatively, the gateway’s Ethernet connection may be used to enable connectivity via WiFi, ADSL or cable connections.
