Q

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.
