Wi-Fi channels A big premise This article is a mix of what I’ve learned in the past few years and more recent studies on the RF physical layer which forced me to investigate in depth concepts like: encoding, spectral mask, Clear Channel Assessment or the Shannon limit.

The protocol is not widely used and Cisco does not support it yet. UWB is useful for real-time location systems, and its precision capabilities and low power make it well-suited for radio-frequency-sensitive environments, such as hospitals....
