Basically a command-line mesh-debugging tool :-) Recommended by Freifunk wiki.

"horst" is a small, lightweight IEEE802.11 wireless LAN analyzer with a text interface. Its basic function is similar to tcpdump, Wireshark or Kismet, but it’s much smaller and shows different, aggregated information which is not easily available from other tools. It is mainly targeted at debugging wireless LANs with a focus on ad-hoc (IBSS) mode in larger mesh networks.

AirView Spectrum Analyzer

The Ubiquiti AirView Spectrum Analyzer running on a Bullet M5

This is a non-libre tool that comes with Ubiquiti's AirOS (that all of their routers run).

It can show both real time and averaged views of power levels (in dBm) plus a waterfall diagram view.

For the Ubiquiti Bullet M5, it operates at frequencies from 4.9 to 6.4 ghz.

It is a Java Web Start tool. Runs fine on Linux.
