This will show you real world utilization information. The client application will connect and run quality tests to the server while you walk around. You can choose which ones you want to actively see.Īctive surveys are done by loading software on a server somewhere in your network. At this point it will list all of the found APs on the left. It is as easy as clicking on the map where you are, walking, clicking when you turn, then clicking stop once you are done. The software is run, you load a floor plan image, set the scale of the image, then click start. Passive surveys are done with a supported wireless NIC. These obviously aren’t going to be perfect, but it is a great way to create a good working model. If you aren’t getting the coverage you want, you can click and drag the AP and instantly see the results of the adjustment. You can then place APs on the map and watch the software predict what the signals will look like. It allows you to load in a floor plan, then quickly add walls and doors of varying materials and thicknesses. Predictive allows you to make a best guess to see what the environment will look like before you install equipment. When you do these surveys using TamoGraph you can do it in one of a few ways: Predictive, Passive, or Active. This information often includes: signal level, signal to noise ratio, signal to interference ratio, and expect physical rates. So what is a site survey? A SS is basically creating a map that shows different information corresponding to the environment where you will/have installed wireless equipment. Often price is the difference between getting the product or not, but in this instance, you have tremendous functionality/features and for a quarter the price! From all the research I’ve seen they are all very good pieces of software perfectly adequate in most instances…although TamoGraph is up to 25% the cost of the others! Price isn’t everything, and I don’t mind paying more for the right product. I’ll go ahead and admit that I’ve not used AirMagnet or Ekahau. You have Fluke’s AirMagnet, Ekahau, and TamoGraph. So there are really only a handful of competitors out there. How do you tame this invisible beast?!?! You need some good site survey kit. If you think about it, Wifi is this moving, living creature…that you can’t see. A tool that I’ve recently been using that I have NO idea how I got along without is TamoGraph Site Survey. I’ve found several tools and techniques lately that really help in design/testing/deployment. I’m doing both high density(HD) and standard user access. As it just so happens I’ve been doing a LOT of Wifi work lately.
