How Can I Evaluate Influence of Co-Channel Interference on Bandwidth on an AP's Air Interface? How Can I Avoid Interference Between Devices Using the Same Channel?
Co-channel interface is a major factor that reduces an AP's maximum throughput. When APs are placed close to each other, their signals have a large overlapping coverage area, resulting in severe co-channel interference. In this case, APs' maximum throughput decreases greatly.
To avoid co-channel interference, adjust APs' transmit power and increase the intervals between APs. You can also use directional antennas and smart antennas to restrict the signal coverage area.
