Today some of the difficulties that wireless networks of local area (WLAN) have in internal spaces, for example, buildings offices, distribution of cubicles between floors, is the adequate coverage that has access to various types of artifacts such as cell phones, laptops, computers, through the wireless connection that provides the various access points (AP) distributed in various spaces where people walk or work. In this paper, we present an analysis of the internal scenarios, considering name of AP, MAC address, channel, standard, bandwidth, type of frame and frequency at the time of the planning of a wireless network. The paper gives the idea about the utility that offers and presents the simulation software AirMagnet Survey in planning and design of wireless LAN Networks 802.11 a/b/g/n/ac in obtaining performance, security and optimal compliance of the network using heat maps. The main contribution of my proposal is the results obtained through experimentation allows obtaining relevant information for the network planner responsible for designing and implementing the wireless LAN. Similarly, it makes use of a series of scenarios for the simulation which are configured with certain characteristics, which allows the verification of the connection speed, frequency of the signal and transmission capacity facing the stages of network congestion.
