Discuss how radio signal interference can affect wireless devices.
What will be an ideal response?
Because wireless devices operate using radio signals, the potential for two signals to interfere with each other exists. Virtually any wireless device can be a source of interference for other devices. Several common office devices emit signals that may interfere with the receivers in a WLAN. These devices include microwave ovens, elevator motors, and other heavy electrical equipment, such as manufacturing machines, photocopiers, certain types of outdoor lighting systems, theft protection systems, and cordless telephones. These may cause errors to occur
in the transmission between a wireless device and an access point. In addition, Bluetooth, WLAN 802.11b/g/n, and ZigBee devices can all operate in the same radio frequency, potentially resulting in interference between such devices in spite of efforts to design these radios to automatically avoid interference.
