Amateur Radio Emergency Data Network
AREDN is a high-speed ad hoc data network for use in emergency and service oriented communication. It can provide regular computer related services over a WiFi mesh network using amateur radio frequencies. The mesh network consists of point to multipoint links utilizing the OLSRv1 routing protocol to create a complete routable network. The core of the AREDN network consists of a special AREDN firmware based upon the popular OpenWRT base. This firmware is compatible with numerous commonly available WiFi endpoints such as those from Mikrotik, Ubiquity, TP-Link and more.
In Tromsø members of LA3T are connected through a AREDN mesh network with a wide network coverage. We have multipoint antennas at Fløya, Kjølen, Håkøya and at LA3T. In addition, any member installation can be used as a relay station in the mesh network. Currently, our network is based on the Ubiquity NanoBridge M5 running AREDN firmware.
This network is a great asset under emergency operations and also has a secondary usage under sport events such as Midnight Sun Marathon. Using portable stations a user can have access to the services within the network from anywhere within the coverage area.
