Difference between signal strength and quality

j2sw — Wed, 07 Jul 2010 15:31:10 +0000

One of the things I have to explain to clients on a regular basis is the difference between signal strength and quality of that signal. It is possible to have a good signal strength but poor quality. Think of receiving a wireless signal as a person with a megaphone at the opposite end of a football field. You might be able to hear the person talking through the megaphone (ie. Signal Strength) but you might not be able to make out their words clearly due to over-modulation, poor quality megaphone, etc. (ie. Signal quality).

The following was taken from an AP on the second floor of my house. This AP connects, via a second wireless card, to an AP on the 3rd floor. As you can see the signal strength is good, but quality is poor.

This link has a bandwidth test running to it. About 3 megs of traffic is traveling over the wireless link. As you can see the quality is quite poor. This results in quite a bit of jitter and poor performance. There could be several reasons for this. Maybe I have some other 2.4GHZ devices interfering. Since it is one level down it could be going through too much material (aka house). I could also have a hardware issue. Antenna not resonating correctly or a card with a bad transmit or receive.
