As of 2009, the IEEE officially defined 802.1l standard has a / b / g / n, 1 shown. As the technology matures and the popularity of chips, related equipment costs also will be reduced. In recent years, 802.11n standard equipment has been gradually popularized in the practical application of hotel engineering, more and more management companies and construction units have adopted 802.11n technology
