Another important feature is programmable Clear Channel Assessment (CCA). A CCA threshold can decrease the receiver sensitivity by changing the absolute receive power level above which the channel is normally considered busy. The threshold is set to -62 dBm by default; however, you can increase the CCA threshold to reduce noise in environments. CCA values can be set independently for root and non-root bridges. You can perform a clear channel assessment at the deployment site by sweeping the UNII-3 band using a spectrum analyzer. Always attempt to choose the channel with the least interference for the bridge link.
You can also adjust the Fragmentation Threshold value in the bridge. This value determines the size at which packets are fragmented (sent as several pieces instead of as one block). Use a lower setting in areas where communication is poor or radio interference exists. Also, you can run the link test at every frequency and watch for signal quality, signal level, and the number of retries. Choose the best channel with good signal quality and minimum number of retries. Notice the relationship between signal level and quality. For example, a high signal level might have poor signal quality indicating potential interference
