Survey
Interference and RF propagation

Interference
Always mount the antennas in an open area for the best signal propagation. Avoid objects that may affect the RF signal. There are a number of objects that can cause interference. Some of the objects that may have a detrimental effect on a signal are shown in Figure .

Avoid the following sources of Electromagnetic Interference (EMI):

  • Fluorescent lights and Fusion 2.4-GHz lighting systems
  • Microwave ovens
  • Air conditioning ductwork
  • Other radio equipment

Always attempt to mount the AP and antennas as far away from these items as possible.

RF Propagation
RF propagation is covered in Module 3. Remember the characteristics listed in Figures , , and when performing a site survey.


Lab Activity

Lab Exercise: Site Survey Active Mode

In this lab, the student will determine the best placement and coverage for the APs through the use of the wireless client adapter site survey utility.

Lab Activity

Lab Exercise: Survey the Facility

In this lab, students will perform a site survey of an assigned location. Students should include channel selections and data rates in site survey results. Antenna selection can also be included.
