Do I need a public, static IP address for ARM600? |
When using standard “off the shelf” public cellular network SIM cards in the Arctic field devices, they are routed over the Internet. ARM600 is a server equipment and it requires a public, static IP address when public networks are used. The public IP address may be associated to the company’s border router and VPN packets can be port forwarded to ARM600. Thus, the public IP address does not need to be associated directly to ARM600’s Ethernet interface. |
|
Why is there no SIM card inside ARM600? |
ARM600 requires more bandwidth than a SIM card can provide, especially when there is a large number of connected wireless gateways. |
|
Can IEC 61850 GOOSE be transferred over this system? |
Yes, with Layer 2 OpenVPN tunnels. However, note that the contemporary cellular networks are not capable of providing the required latency and speed for higher speed GOOSE message classes. |

Our company has a private APN in cellular network. Do we need ARM600? |
Arctic Gateways/Controllers can be used without ARM600, if a private APN is available. However, ARM600 is still highly recommended because of the Patrol centralized management functionality, secure VPN tunnels, firewall and for not needing complex D- NAT configurations in the field devices. |
