Network Discovery Tools
There are several service programs that can assist in visualizing or mapping an AREDN® network, as well as for viewing local RF conditions near your node. Some of these programs are discussed below.
KG6WXC MeshMap Network Visualizer
Eric KG6WXC created this useful tool and makes it available as an open source project. MeshMap can be installed on any mesh services computer having LAMP software, which allows it to run on a Raspberry Pi in your shack or in the field. MeshMap runs continuously and discovers/polls live nodes to display their current configuration, services, and network link information. It maintains a persistent database of all nodes that have been discovered.

KP4MSR MeshMap Network Visualizer
Manuel KP4MSR originally created this software for the Puerto Rico AREDN® network, with a current fork and rewrite of the code maintained by Tim KN6PLV. This program does not run continuously and does not maintain a persistent database of nodes, so it is less resource-intensive on the network. Once the static pages are built, it can be run on any device with a web server, including on a node with enough free memory.

KN6PLV Network Waterfall Scanner
Tim KN6PLV created this program to assist with discovering the RF conditions around your node. It is installed as a node package which is available here: KN6PLV Waterfall. Once installed it is accessible via URL from any web browser on the network (
http://[NODENAME]/cgi-bin/waterfall). It will disconnect your node from the mesh while it continuously scans for nearby RF signals, so it does require authentication with the node’s login credentials in order to run. The Spectral View shows the strength of nearby signals, while the Waterfall maintains a record over time of the RF environment.
