Given: ABC Company is an auto parts manufacturer, and they have contracted you to perform a WLAN site survey to relieve their wVoIP quality problems. Your initial site survey shows a minimum signal strength of -75 dBm around the facility. This is less than the -70 dBm recommended by the wVoIP manufacturer. You recommend increasing each AP’s output power, and after a follow-up site survey, the new minimum signal strength is -60 dBm. Unfortunately, the wVoIP problems are now worse than before.
How can you remedy this problem?
A.
Increase each AP’s output power even further to overcome the RF noise problems.
B.
Install directional antennas that focus the RF signal away from obstacles causing multipath.
C.
Increase each wVoIP phone’s output power to overcome the RF interference sources.
D.
Change the polarity of each AP’s antennas.
E.
Move the APs closer together.
