Wireless Networking: Signal Behavior


When wireless signal hits an object it does not just stop or bounce straight back it could turn, bend, breakup, slow down, or even turn a corner. If you do not take into account these possible senerios wireless network could have large big issues that could plague network

distribution :. Scattering takes place when a wireless signal hits an object that has many irregular angels causing the signal to shoot off in many directions. This could happen when a signal hits a mountain side, hills or large buildings

Reflection :. Reflection happens when the signal bounces just completely share. This can be good and bad. Reflection can be good because customers do not need to rely on LOS (Line or Sight) service. Signals can be trasmitted and bounced off large buildings to the client. Reflection can be bad of it causes signals to bleed into uneeded area

refraction :. Refraction bends the wireless signal as it passes through the medium of greater density than its origin. If you signal has to travel thought industrial smoke stacks valleys warmer air pockets this will produce refraction

Absorption :. Shoot your signal at a larger brick building and signs could be sucked up and disappear

diffraction :. This is often confused with refraction. Diffraction occurs when your wireless signal hits a very large object, slows down and actually turns around the corner. This is great if you want your signal to bend around the corner but if you do not suck. Plus it slows down your signal making it weaker.

If you are having trouble with weak signals or clients being dropped from the WLAN you may be interference from above signal behavior. Also know that the signal can reflect or turn corners will help you avoid potential security threat.
