Portland, Ore., was the big win for MetroFi, back in the day, the flagship network that never was: MetroFi was unable to make its gear and business model work in a way that let them move forward, and I won't rehash the process that led them to exit the working world. However, the company left behind hundreds of SkyPilot distribution and backhaul nodes, and a $30,000 bond to remove them. The city estimates the cost will be double, and the equipment has nearly no resale value.
Mike Rogoway of the Oregonian reports that the first batch of removed gear will be handed off to Personal Telco, one of the longest-running community wireless efforts in the world, which operates a variety of free service around town. The group hopes to be able to repurpose the nodes, but I'm dubious. SkyPilot's end-point nodes had two radios, one designed for 2.4 GHz 802.11g access, and the other at 5 GHz to work with its unique point-to-point system.
(SkyPilot's approach had 8 antennas in a sectorized in its backhaul units that used GPS time synchronization to make precise, very high power point-to-point connections at scheduled intervals. One backhaul node could deliver narrow extremely high-signal power zaps of wireless communication in 8 directions seemingly "at once.")
This means that the Wi-Fi nodes have to be served by SkyPilot backhaul devices, which in turn require precise orientation and placement along with back-end management software, which was typically licensed separately.
Personal Telco suggested to Rogoway that it might disassemble them for parts, but four-year-old gear that's designed for this particular a purpose probably has little of interest, even for free.
