Avoiding Co-Channel Congestion for 2.4 GHz Access Points

A

When installing access points (APs) that use the 2.4 GHz frequency, it's important to avoid co-channel congestion, which occurs when multiple APs use the same channel, causing interference and degrading wireless performance.

To avoid co-channel congestion, the recommended approach is to use different non-overlapping channels. In the 2.4 GHz frequency band, there are three non-overlapping channels: 1, 6, and 11. This means that these channels do not overlap with each other and can be used simultaneously without interfering with each other.

For example, if you have three APs, you could set each AP to use a different non-overlapping channel: AP1 on channel 1, AP2 on channel 6, and AP3 on channel 11. This ensures that each AP is using a separate channel, reducing interference and improving wireless performance.

Option B (one overlapping channel) and option D (different overlapping channels) are not recommended because they both involve using overlapping channels, which can cause interference and reduce wireless performance.

Option C (one non-overlapping channel) could work if there is only one AP, but if multiple APs are being installed, it's important to use different non-overlapping channels to avoid co-channel congestion.
