Which of the answers listed below refers to example of an unlicensed wireless frequency band? 900 MHz 2.4 GHz 5 GHz 5.8 GHz All of the above

All of the above

Which of the following actions would be of help while troubleshooting intermittent wireless connectivity problems? Check physical connections (e.g., loose/faulty cables, expansion cards, etc.) Increase the signal strength (adjust power level controls on a WAP, move closer to a WAP, or switch to a different WAP) Configure a WAP to operate on a different wireless channel (1, 6, or 11) Check for interference from wireless devices operating in the 2.4 GHz frequency band (e.g., cordless phones, Bluetooth devices, or microwave ovens) If possible, check the network's performance on a different frequency band (2.4 GHz or 5 GHz) Reduce the number of wireless devices using up available bandwidth on the network All of the above

All of the above

A common example of channel overlapping in wireless networking would be the 2.4 GHz band used in 802.11 networks, where the 2.401 - 2.473 GHz frequency range is used for allocating 11 channels, each taking up a 22-MHz portion of the available spectrum. Setting up a wireless network to operate on a non-overlapping channel (1, 6, and 11 in this case) allows multiple networks to coexist in the same area without causing interference. True False
