Wallplug-01
You need a Meraki (wireless mesh router) somewhere to use this, but it’s all part of a free internet effort for low-income housing – using one of the Merkai’s and these Wi-Fi repeaters it looks like you could cover up to 4 apartments with a total of 50 on one DSL line…

The standard Meraki Mini housed in a Wall Plug case for fast, secure, commercial-grade installations. Everything is inside this small enclosure: Mini, power supply, and on-board antenna. Installation is as simple as plugging it into an outlet and securing it via the outlet’s center screw. Highly recommended for apartments, hotels and public areas as there are no exposed wires or lights and its bone color blends into most walls. Even includes a Torx screw for extra security.
