What is a difficulty in locating a wireless client based on the RSS value when received by only one AP?

  • The orientation where the client is situated in relation to the AP cannot be determined.
  • The RSS value is affected by the air temperature.
  • The distance from the client to the AP cannot be accurately determined.
  • The RSS value is affected by moisture in the air.

Explanation: To improve the accuracy of locating a device, an AP can use the received signal strength (RSS) of a client device as a measure of the distance between the two. However, if the distance is measured from a single AP only, it is difficult to determine where the client is situated in relation to the AP. In the case of an indoor AP with an omnidirectional antenna, the client could be located anywhere along a circular path of fixed distance because the received signal strength would be consistent at all points on the circle.
