Wireless communication solutions utilizing public cellular networks offer users a cost-effective and secure platform for substation automation, condition monitoring, remote maintenance and easy access to remote locations. The solution is fully application independent, meaning that any type of remote application can be connected to any central application. For utilities, these remote applications can be e.g. pole-top equipment or ring main units. The central application in turn is typically a supervisory, control and data acquisition system (SCADA). In addition, special applications can be built to comply with user requirements.
A typical complete communication system consists of Arctic 600 series gateways and a central M2M Gateway ARM600. A completed system offers secure VPN tunnels from the central location to the remote Arctic 600 series gateways. The condition monitoring application, called Patrol, supervises the communication links and alarms the user of any disruptions. In addition, automatic back-ups of 600 series gateway configurations are taken and stored in the M2M Gateway ARM600. Patrol also offers statistical data of the network usage, speed and uptime.
Thanks to the routing capabilities of the solution, it is possible to connect entire Local Area Networks together. For example, a network in a remote substation can be connected to the company internal network.
