IEEE 802.11af

IEEE 802.11af is a standard that enables Wi-Fi devices to operate in TV broadcast bands (lower-frequency TV white spaces). This allows wireless networks to use these unused TV channels, especially in rural or underserved areas, providing better coverage and potentially less interference. By intelligently sharing TV spectrum, 802.11af aims to extend Wi-Fi connectivity beyond traditional Wi-Fi frequencies, improving internet access and network performance in challenging environments. It involves sophisticated cognitive radio technology to detect available channels and avoid disrupting TV signals, ensuring safe and efficient wireless communication in designated spectrum.
