Which of the following environmental conditions can prevent network transmission on an 802.11b network?
1. Walls that block line of sight
2. Bright lights
3. >>Electromagnetic interference
4. Humidity
Explanation : An 802.11b network is a wireless network that transmits data over radio waves. Therefore, it is subject to electromagnetic interference, such as electrical motors or other electrical devices. Some cordless phones have also been known to interfere with 802.11b transmissions.
Radio waves do not depend on line of sight. Therefore, walls that block the line of sight will not be a problem. However, some walls might contain material that prevents radio transmission.
Bright lights do not interfere with radio waves.
Humidity does not interfere with radio waves.
Objective: Networks
