A company is deploying a wireless network in the distribution facility in a Boston suburb. The warehouse is quite large and it requires multiple access points to be used. Because some of the company devices still operate at 2.4GHz, the network administrator decides to deploy the 802.11g standard. Which channel assignments on the multiple access points will make sure that the wireless channels are not overlapping?

In the 2.4GHz frequency band used by 802.11g, there are up to 14 channels available (depending on the country), with each channel being 5MHz apart. However, because the Wi-Fi channel width for 802.11g is 20MHz, each channel overlaps with several of the adjacent channels. To avoid overlap, it is recommended to use channels that have at least 20MHz of separation from each other.

In most countries, including the United States, the non-overlapping channels that are commonly used are 1, 6, and 11. These channels are chosen because they have sufficient separation to ensure that their frequency bands do not overlap.

So, the correct channel assignments to ensure that the wireless channels are not overlapping would be:

channels 1, 6, and 11.

This spacing allows for the use of multiple access points in close proximity without interference between them, which is critical in a large environment like a distribution facility.
