A customer installs a wireless access point at home in the closet next to the kitchen. The customer mentions that the wireless communication performance seems degraded when the cordless phone or the microwave oven is in use. What is the possible reason for this degradation?

• The access point is close to walls.
• The cordless phone joins the WLAN and shares the available bandwidth.
• The wireless signal is in the same radio frequency range as the household devices are in.
• The access point is on the same electrical circuit as the phone base unit and microwave oven are.
• The surge of electricity when a microwave oven is in use disrupts the operation of the access point.

Explanation: Because wireless networks use air as a medium, interference from other sources commonly cause degradation issues. Sources can include cordless phones, fluorescent lighting, microwave ovens, and other wireless devices that use the same frequencies.
