What’s The Biggest Cause Of Co-Channel Interference?

In my last blog, What is a Clear Channel Assessment?, we discussed the difference between the signal detect (SD) threshold and the energy detect (ED) thresholds used by Wi-Fi radios to determine if the RF medium is busy. The ED threshold is used to detect any non-Wi-Fi transmissions while the SD the threshold is used to […]

What is a Clear Channel Assessment (CCA)?

The CSMA/CA protocol utilizes a line of defense to ensure that any Wi-Fi radio does not transmit while another is already transmitting on the same channel. The 802.11-2016 standard defines a physical carrier sense mechanism to determine if the radio frequency (RF) medium is busy. Physical carrier sense is performed constantly by all Wi-Fi radios […]
