Upstream Backhaul Connection
Neighborhood Othernet Wifi
We use Ubiquiti LiteBeam AC 5GHz 120 Degree 16dBi Sector antennas to distribute connectivity to the 5 blocks surrounding POWRPLNT.
Connecting the Equipment
We use a Mikrotik OmniTIK to connect the sector antennas, the directional backhaul antenna and the othernet server.
Our central server is housed at POWRPLNT in Bushwick, our central node. In terms of form factor we needed something small and quiet that could be left in a room for long periods of time. We also needed something with a fair amount of processing power so we could scale up all of our Othernet Services.

Inside the ethernet cable, there are 8 color coded wires. These wires are twisted into 4 pairs of wires, each pair has a common color theme. One wire in the pair being a solid or primarily solid colored wire and the other being a primarily white wire with a colored stripe (Sometimes ethernet cables won't have any color on the striped wire, the only way to tell which is which is to check which wire it is twisted around). Examples of the naming schemes used are: Orange (alternatively Orange/White) for the solid colored wire and White/Orange for the striped cable. The twists are extremely important. They are there to counteract noise and interference. It is important to wire according to a standard to get proper performance from the ethernet cable. The TIA/EIA-568-A specifies two wiring standards for an 8-position modular connector such as RJ45. The two wiring standards, T568A and T568B vary only in the arrangement of the colored pairs. Tom writes to say "...sources suggest using T568A cabling since T568B is the AT&T standard, but the US Government specifies T568A since it matches USOC cabling for pairs 1 & 2, which allows it to work for 1/2 line phones...". Your choice might be determined by the need to match existing wiring, jacks or personal preference, but you should maintain consistency. I've shown both below for straight through cabling and just T568B for crossover cabling.
