Municipal WiFi just won’t die. The scheme has failed in city after city, even stumbling in tech-heavy Silicon Valley, yet companies have continued, on and off, to get funding. The latest is SkyPilot Networks, with a comparatively small $3.4 million (compared to its $70+ million total).

SkyPilot makes broadcasting equipment like base stations, as well as tools for mesh networks like antennae. It’s mesh networks, in fact, which are driving much of the remaining growth for city-wide WiFi — mostly for use in security systems, or for emergency responders like fire departments.

The funding is the last bit needed to get SkyPilot to profitability, the CEO said in in a release. August Capital and Mobius Venture Capital provided the funding, along with other existing investors.
