2.5. Task 2.5: Measuring Wireless Signal Strength
Various factors influence the signal strength in your wireless LAN, including proximity to the wireless access point (WAP), output capability of the access point, interference from other wireless/cordless devices and electronics operating on a similar frequency, and physical obstructions.
This task suggests various scenarios that you can duplicate while you note the effect on wireless signal strength using your own equipment.
You are interested in positioning your access point in the best place possible for overall reception. You must consider sources of signal interference and blockage, as well as how far away wireless clients are expected to be.
