I am conducting some inside site surveys, I have a lot of documentation on doing a survey and have good equipment but one question I have is what should be the minimum signal strength or quality that I want to look for? For example I am thinking that a signal strength of 10 percent is as low as I want to go and would consider that the edge of the range for that access point. I am just wondering if there is a suggested limit or rule to go by.
The tool I am using it is easier to see strength than quality. I have always been putting more emphasis on quality because you are right that quality is more important than strength. We have a Fluke Optiview with the wireless option and it does a good job showing strength and throughput. The big point you pointed out is application requirements which not only is going to be hard to measure, we have a lot of different users with different requirements.
Thanks for the info and stimulating some more thought on this.
Our rule of thumb is a minimum Mb connection. As an example, we will guarantee at least 2 Mb at any location that is covered by wireless. This works well for us. Keep in mind that the type of device you are using makes a big difference too. We use mostly hand held units for our warehouse operation. The radio is not as strong as a laptop with a wireless NIC. With this in mind, we survey with the hand held unit.
