[WLAN]Q&A: How Can AP's Channels Be Distributed to Avoid or Reduce Internal and External Interference?

When interference exists in the radio environment, the interference affects radio signal transmission and may cause signal transmission failure. How to avoid and reduce the interference?

Here's the answer.

Use a cellular channel distribution to avoid channel overlapping. For example, there are only three non-overlapping channels in the 2.4 GHz frequency band: channel 1, channel 6, and channel 11. A proper channel distribution can greatly reduce co-channel interference on a WLAN network. Follow these principles when distributing radio channels:

• Use non-overlapping channels in adjacent areas.

• Adjust APs' transmit power to avoid co-channel interference between areas.

• Use a cellular channel distribution so that channels can be multiplexed without causing overlapping coverage areas.
