According to the U.S. [[~~FCC~~Federal Communications Commission]] (FCC), UWB can use from 3.~~1–10~~1 to 10.6  GHz. That means it could interfere with [[WiMAX]], [[3G]] or [[4G]] networks.{{citation needed\|date=April 2014}} ==References== ~~DAA is enforced only in some European countries.~~ {{reflist}} ~~==See also==~~ * [[Ultra-wideband]] == External links == * [https://web.archive.org/web/20080512201116/http://www.wisair.com/technology/detect_avoid/ Detect & Avoid] --– Short page on DAA * [https://web.archive.org/web/20070922071627/http://www.wisair.com/wp-content/DAA_WP.pdf Detect and Avoid Technology: For Ultra Wideband (UWB) Spectrum Usage] --– whitepaper presenting an experience with DAA.
