New Install Site

This past Monday I toured a New Site for installation of wireless hardware. This site is a key piece in the network design as it links several area's together. The building is a old book press that is being transformed into and apartment complex. This site has by far had the nicest route to the roof. The building is so large that we are placing equipment in two different locations on the roof.



This is a overall shot of the site



We are contemplating using a non-penetrating roof mount here



This is a diagram of the layout of equipment in the A/C Pit on the roof, having the uni-strut there will make the installation much faster.



On the other side of the building there is another grouping of A/C units with a sewer stack in the center that we would like to band clamp a light aluminum mast to with a NanoStation2 strapped to it to link a site 3 blocks up obscured by trees.

Simple Command to Search for a Known ESSID

I was looking for a simple way to scan for a specific ESSID and display all of the information about it. So with some help I came up with this.

pyramid:/# iwlist ath1 scan |grep linksys -B1 -A8

          Cell 02 - Address: 00:18:F8:EF:XX:XX
