We use 2.4 GHz 802.11g or 802.11n WiFi gear with omni or semi-directional antennas to provide connectivity to devices such as laptops and smartphones at street level and within buildings. We are currently using a variety of gear including Ubiquiti Picostation M2 HP and Ubiquiti Bullet M2 HP routers for outdoor APs. | |||
We | We're currently deploying a wireless backbone of point-to-point and point-to-multipoint links. These devices are mounted in high places such as on rooftops, flagpoles, or antenna towers. We currently have firmware support for a variety of Ubiquiti M5 (802.11n) routers, such as NanoBridges, NanoStations, and Rockets. As of June 2018, we're currently working to establish gigabit links with 5GHz and 24GHz Ubiquiti airFiber routers, as well as 60GHz Microtik wireless wires. | ||

All routers run the Babel mesh routing protocol. The street-level 2.4 ghz routers should ideally be able to function in the event that e.g. an earthquake takes out all of the point to point and point to multipoint rooftop nodes (more alignment sensitive) and the mesh should remain functional, though it could become segmented. | All routers run the Babel mesh routing protocol.

The relays / [[VPuN]] servers (see the internet connectivity section) also run Babel, so mesh traffic can flow from one part of the mesh, through the internet, through a relay, and into another part of the mesh if some of the mesh nodes are connected to the internet. | The relays / [[VPuN]] servers (see the internet connectivity section) also run Babel, so mesh traffic can flow from one part of the mesh, through the internet, through a relay, and into another part of the mesh if some of the mesh nodes are connected to the internet. | ||

* We have the opportunity to establish a Gigabit link between Oakland and San Francisco, with a connection in San Francisco near the Western most part of 24th street in the [https://goo.gl/maps/TzMBTsadiCL2 Noe Valley] neighborhood. This location has great line of sight with many locations in the East Bay. We would like to establish a relationship with anyone that can grant permission to mount equipment on Laney Tower at [http://www.laney.edu/wp/ Laney College] in Oakland. | * We have the opportunity to establish a Gigabit link between Oakland and San Francisco, with a connection in San Francisco near the Western most part of 24th street in the [https://goo.gl/maps/TzMBTsadiCL2 Noe Valley] neighborhood.
