SCADALink Nomadic Wireless Networks are designed for long distance wireless connectivity for portable and nomadic  industrial applications such as Oil and Gas, Mining, and Industrial for Frac Water Transfer, Offset Well Monitoring, and Dewatering, Water Transfer/Bypass. Mobile applications like this may involve over 20 nodes spanning over 20 miles. The system requires easy and rapid deployment; and highly reliable operation with minimal maintenance. The Nomadic networks feature long distance combined with high speed operation allowing real time monitoring and control operations.

Multiple Wireless Technologies

Nomadic networks feature multiple wireless technologies including 900 Mhz Unlicensed Radio, Cellular, WiFi, Satellite and Wireless Sensors technology. The basic Nomadic network features 900 Mhz with fail over to Cellular to allow for ubitqitous connectivity.  High power 900 Mhz Unlicensed Radio is used as the primary connection. This allows connectivity in areas without any terrestrial network. Cellular connectivity when available provides redundancy and backup. Additional connectivity including satellite options are possible. WiFi Gateways at each node allow untethered access by users via laptop or tablets.  Security is provided via encryption, passwords, and VPN networks.

Network Connectivity

All nodes will have full network connectivity to flexible connectivity of SCADA host, RTU. RS232 and RS485 connectivity will be provided  at each node for serial devices. Network connectivity allow network based fail over mechanisms.

System Operation

Distances between nodes will range from 1 to 5 miles depending on the terrain, the node locations, and the antenna heights.  Cellular connectivity for backup will depend on the cellular coverage footprint and antenna ights.  System data rates range from 300kbs to 1 Mbs, allow full SCADA control and web browser access.

Network Dashboard

A key feature of the Nomadic network is a system dashboard that provides communication monitoring and diagnostics. This is especially important in the set-up and operation of networks in areas with rugged terrain.  Monitoring and diagnostics ensure optimum connectivity. At sites with unreliable signals, repeater nodes or elevated antennae may be required

Mobile Network SCADA


The architecture as show above provides full network connectivity for devices on the node to connect to the SCADA host via Ethernet. WiFi network access is provided at by a WiFi hotpot at every node. WAN connectivity is provided at the Master Node, so the network can be provided with Cloud connectivity. WAN connectivity can be via VSAT, Microwave, or Wireless Broadband. Any internet access only provided via the Master Node to provide network security.
