Wires Are Evil : A look inside the Nanostation 2
“… . The Nano Station 2 is a small, waterproof CPE with a 400mw 802.11b/g radio and a dual polarity 10dbi antenna. It does POE (with included adapter), mounts to a pole, and has an external SMA (regular, not reverse polarity) connector. Added bonus, LEDs for RSSI while you set it up. It runs AirOS, which is Ubiquiti’s linux variant, and it’s only a matter of time before they’re running OpenWRT (check the support page for updates on firmware). As far as price goes, nothing out there beats it. It even comes with an offer for a free shirt! …”
