The objectives of this work are the analysis of wireless networks based on IEEE 802.11a, 802.11b 802.11g and 802.11n standards. We study various parameters and characteristics to later carry out a statistical study on its current utilization. The parameters studied are: standards used, bit rates supported by the devices, rates required by APs, security features supported, use of frequency channels, type of wireless networks, hardware manufacturers, coexistence between standards and efficiency of the management frames. The methodology of the work consisted in sniffing IEEE 802.11abgn frames with a specific software and hardware. Hardware tools were portable devices and dual band antennas (2GHz and 5GHz). As for the software, Kismet was the packet sniffing application the output of which was analyzed by a custom-made Java application, responsible for providing statistics about the aforementioned network configuration parameters and features. The results allowed us to obtain an overview of the current state of 802.11abgn networks and the coexistence issues that arise
